An excellent source of water requiring only disinfection would have a turbidity of 0 to 10 units. A good source of water supply ra~uiring usual treatment wo~1ld have a turbidity of drinking water and finished 10 to a~o units. For disinfection purposes, rdw sources should be limited to 5 turbidity units, water should have a maximum limit of 1 turbidity the water enters tha distribution system. Most where people find water with 5 or more turbidity units obJectionable. The water ~uality requirements for particulates varies among industrial uses. At one extreme, rayon manufacture requires water with· only 0.3 turbidity units, wheraas water use~.for cooling can have up to ~0 turbidity units. Most other industrial usas re~uira maximum turbidity levels within this range. Placer mining is one industry where water containing turbidity or suspended solids levels significantly higher than 50 units may be acceptable. 4.0 PARTICULATES REQUIREMENTS FOR RECREATION The noticeable threshold for water contact recreation is 10 turbidity units and the limiting threshold is ~0 units.

By comparison, only limited numer1cal data are available regard1ng the effects of sediment on fish emergence time and population changes. The percentage of fines and level of spawning gravel embeddedness ~re critical factors to developing eggs and emerging fry. I r• genera 1, sal rnon, trout, and char egg survival and emergence success are adversely affected when the fraction of fine sediment exceeds 20 pet•cent. Although the critical particle si%e is highly variable among species, sediment smaller than 3 mm in diameter appears to be the most deleterious to fish egg survival, emergence success, A number of investigators empha~i%e· the deleterious effect of particles smaller· than 1 mm in spawn~ng gravels. In addition, it is generally recogni%ed that deposited sediments smother fish eggs and benthic macroinvertebrates by blanketing the substrate. The adverse impacts of a wide range of suspended solids and turbidity levels have been reported for a diversity of aquatic plamts, macroinvertebrates, devel,~pmer.t.

In many instances, th• data presented in on• investigation either do not support or cannot be readily compared to the results of other investigations. An organism's level of sensitivity to suspended solids is dictatad by its age, specias, relative mobi 1 ity, feeding and reproductive habits, tha season, the size and nature of the . sadimant, the duration of exposure, the general health and stress level of the individual, and the degree and d~ration to which the individual was previously expo;:,sed. Furt het•m.;:,re, an individual's level of susceptibility depend$ to some degree upon its origin. For instance, one REVIEW DRAFT 9/09/85 PAGEt¥ - - - ~ ~ - - - r - - investigator corts i derab 1 y indicates that hatchery-raised coho salmon are more sensitive to suspended solids than are wild coho. do not Moreover, the results derived from laboratory experiments necessarily reflect field conditions be6ause of the stress factors involved and because many organisms possess innate adaptation capabilities in response to changes in their environment. These variables are not always presented in the literature. It is relatively common to find the results from one particular study cited in three or more literature reviews. Upon reviewing the original document, it appears that some of the data have been presented without discussing other pertinent factors. ConseQuently, it is difficult to draw definitive conclusions concerning the impact of a specific suspended solids concentration or turbidity level on a particular species or age class of organism. With these limitations in mind, the following summary statements are made co~cerning the effect~ of suspended solids and turbidity on freshwater aqu~tic organisms. Lethal suspended solids concentrations vary widely depending on the species and duration of •~posure. Arctic grayling can survive high concentrations (10,000 mg/L) of suspended solids but not extremely high concentrations <2~0,000 m;/L) for a few days. High levels of turbidity (up to 8200 NTU) appear to have no adverse effect on grayling survival. Rainbow trout are capable suspended mortality several of withstanding 30 to 90 ppm of certain types of solids for several months bYt suffer significant <~0 percent> at levels greater than 100 mg/L for weeks. At extremely nigh levels of suspended solids (160,000 mg/L), rainbow trout suffer total mortality in 1 day. Total egg mortality may occur at much lower concentrations (less than or eQual to 2~00 mg/L) in less than a ~eek. The amount of sediment required to cause ~0 percent mortal1ty in JUVenile coho salmon in 4 days is much higher in November <35,000 pprn) than in August ClZOO ppm). Chum salmon egg survival is decreased by about half wh•n suspended solids levels are in~reased from 97 to 111 mg/L. RE'v'IEW DRAFT 9/09/8~ PAGE V In general, salmonid feeding, growth, reproduction, and behavior are not significantly affected by turbidity levels less than 25 mg/L. at 35 NTU or suspended solids concentrations less than 30 An exception is the cutthroat trout, which c~ases feeding ppm suspended solids. With one exception, there is no indication that suspended solids concentrations less than SO mg/L have any adverse affect on salmonid gill or fin tissues, or respiratory functions. In one instance, an in ~i~Y concentration of 34 mg/L produced moderate to marked gill hypertrophy and hyperplasia in Arctic grayling in 5 days. Furthermore, suspended may be stressful to 1 eve l s. solids concentrations as low as 50 mg/L grayling, as indic•ted by blood glucose Algal-based productivity may begin to be reduced at turbidity levels greater-than about 5-NTU in ~-trearns and lak-~s. Ror.:•ted aquatic plants may be absent at suspended sol ids concer1trations greater than 200 mg/L. Benthic macroinvertebrate populations may be adversely affected by suspensions of 40 mg/L or more and zooplankton may be harmed by more than sa mg/L suspended solids. Lethal and sub-lethal effects of sediments have been determined for a diversity of marine organisms. Numerical data pertain primarily to the effects of suspended solids and turbidity as opposed to sediments deposited on the bottom. Much of the work done in the marine system involves estuarine invertebrates. With few exceptions, marine invertebrates are rnore tolerant of high suspended sol ids concentrations tharr are anadromous fish and freshwater invertebrates. Primary production has been reduced at turbidity levels of 41 JTU near offshore mining activity. However, mixing and ~ilution limited the eKtent to which pr1mary ~roduction was reduced by localized or temporary sediment increases. The let Mal sus;:~ended solids concentration for adult bivalves, REVIEW DRAFT 9/0S/85 PAGE VI - - - - - crustaceans, tunicates, and polychaetes is in all instances greater than 400 mg/L and in most cases greater than 1500 mg/L. The survival of a ~ariety of estuarine fish eggs and. larvae is not reduced by suspended solids concentrations iess than 100 mg/L. However, the feeding rate of larval herring is significantly reduced at 20 mg/L. Tha sub-lethal effects of suspended solids and turbidity on mollusks are quite variable. The feeding rate of some oysters is unaffected at 100 to 700 ppm turbidity. Some clams cease feeding at 1000 JTU. The water pumping rate of the American ,;:,yster is 101) mg/L. significantly The feeding reduced at concentrations greater than rate of the mollusk ~~~eig~l~ sp. is significantly reduced at 200 mg/L. Clam eggs develop normally in silt suspensions of 3000 mg/L, whereas American oyster eggs are affected by. silt concentrations as low as 166 mg/L. Seed scallops exhibit elevated respiration rates at 250 mg/L or greater. The mussel !!!~ti.l~~ sp. is well adapted to silt concentrations up to SO mg/L. The shell growth of certain gastropods is decreased when natural suspended solids are increased to 250 mg/L. 5.0 CONCLUSIONS 1. The level of protection afforded by the existing Alaska particulates criteria for the designated water uses is generally supported by scientific data. However, a number of proposed modifications to the existing criteria have been made to attain the best criteria based on information presented in this report. Use categories for which turbidity criteria have been retained include industrial water su~ply and contact and secondary recreation in fresh water. Under the proposed criteria, no distinction is Mada between lakes and streams for recreational uses.

Set t 1 ea b l e aquatic biota solids have direct and detrimental effects on and habitat by smothering fish eggs, alevins, and invertebrates, reducing intergravel flow, and by coating aquatic vegetation, thus reducing the potential for photosynthesis. Solids in suspension can cause invertebrate drift, cause fish to avoid previously usable habitat, prevent fish from seeing their prey, and cause physical damage such as gill irritation to fish. The lethal tolerance of salmonids and other a~uatic organisms to suspended solids appears to be relatively high. In most instances, sublethal effects occur at Much lower concentrations. Turbidity prevents the growth and photosynt~e­ sis of green plants and can also cause fish to avoid otherwise -suitable habitat and prevent them from seeing their prey. 4. Gravimetric techniques represent a mora accurate measure of the affects of suspended solids on aquatic biota while optical measurements may be more appropriate for photosynthetic or aesthetic purposes. 5. Sed irner1t is, surface water. by volume, the greatest single pollutant of The transport and deposition of natural sediments is often related to local storm events and stage of hydrograph. The fate of man-induced sediments differs from natural sediments in that the former is not necessarily ass•:.ciated with or dependent upon fluctuations in runoff. In some instances man-caused magnitude, duration, and sediment fre~uency inputs than are greater in natural inputs. Furthermore, with natr..tral the timing of man-caused inputs may be out of phase occurrences. Consequently, the ultimate fate of man-caused •adiments may be different than natural sediments. REVIEW DRAFT 9/09/S~ PAGE lX Also, the sequence of artificial sediment lc•adirtg may ind1..1ce abnormal behavioral responses in resident and anadromous fish. 6. Because many investigators have not adh~red to the definition of turbidity and instrument design specification applied by §1sn9sr9--M~~bgg~ __ fgr __ 1b~-s~sm1ns1~gn_gf_~s1~r-sn9 ~s§!§~s~.@r, there is a significant amo1.tnt •jf variability in the way turbidity is mRas~rea and reported. This factor makes it extremely difficult to assess and compare the effects of turbidity on various water uses. Common sour~es of error 1n turbidity measurements include the ~ollection of representative samples in the field, extraction of subsamples, dilution technique, and reporting data to the ~orrect number of signifi~ant figures. Although it is recognized that turbidity measurements may be diffi~ult to evaluate, turbidity is the most applicable of th• potential optical p&rama~ars for w1despr~ad •.tse in Alaska. 7.

Turbidity is generally less than 5 to 10 NTU, but may be 25 to 50 NTU during periods of high water. Settleable solids levels rarely exceed o. 1 ml/L. Glacial stre_ams carry large suspended sediment loads during-summer, but normally become clear water streams during winter. During summer, glacial streams and lakes may exceed 1000 mg/L total suspended solids and turbidity typically ranges between 50 and 1000 NTU. Wetlands are a common and important type of a~:~uatic habitat in Alaska. Many lakes are surrounded by both tundra bogs and marshes with emergent a~:~uatic plants. These peripheral wetlands furnish energy to the lake system in the form of insects, plankton, and plant material. The same is true for many rivers. Streams often receive much of their water from surrounding wetlands. Wetlands also supply nutrients and furnish rearing areas for fish such as coho salmon and grayling. Nearly all wetlands in Alaska can be classified as clear water systems. Hence, they seldom exceed 1 to 2 m;/L total suspended solids and turbidity is typically less than 1 to 2 NTU. 2.2.2 Marine Measurements of turbidity and/or suspended sediment load within the marine waters of Alaska are highly variable and dependent on several factors such as season, proximity to sediment sources <mainly rivers>, distance from shore, current structure, depth, temperature, and salinity. Particulates data summarized herein are based on Burbank <1974) and Sharma <1979) except as otherwise noted. Within Boca de Quadra and Smeaton Bay in southeast Alaska, the suspended sediment load is relatively low. The mean water column concentration in the central basins is less than 0.5 mg/L and less than 1.0 mg/L in the inner basins <Burrell 1984). Conversely, Taku Inlet, also in southeast Alaska, Mas REVIEW DRAFT 9/09/85 PAGE 10 - - ~I - - - - - - - - - - - - e)(traordinarily the Taku Riv•r load at the high suspended sediment levels from discharge of and subglacial streams.

Concentrations of suspand•d sediment in continental shelf surface waters off Icy Bay in the northeast Gulf of Alaska generally decrease seaward Ci.a., 1.3 mg/L nearshore and 0.1 mg/L at 6~ km from snore in March>. The particulate concentration is relatively constant with depth from the surface to within about 10 m above tna bottom, and from snore to 30 km offshore at the 100 m depth. A steady increase in suspended solids levels within 10 m of the bottom suggests the presence of a naphloid or turbid layer along the bottom. In the northern Gulf· of Alaska during heavy runoff, t~a glacial streams typically carry 1000 to 2000 mg/L of suspended solids. Peak discharge in the Copper River in summer carries appro)(imataly 1700 mg/L of suspended material at the delta. Offshore from the Copper River during low discharge and minimal glacial malt, surface values as high as 30 mg/L are present. Coarse sediments rapidly settle out within the first few kilometers, depending on the anergy of the environment. At distances greater than 10 km offshore, surface suspended solids levels of 2 to 10 mg/L are typical. The lowast concentrations indicated by ERTS imagery in waters greater than ~0 km offshore generally range from 1 to 3 mg/L. Suspended sediment concentrations in Cook Inlet vary from 2000 mg/L near Anchorage to 1.0 mg/L near the east side of the Inlet mouth. The Matanuska River, ona of several sediment sources in the Inlet, has suspended sediment levels that appro)(imata 3800 mg/L. The suspended load is mostly of glacial ori§lin and ma)(imum values occur at depths of appro)(imataly 10 m near the Inlet head. Concentrations increase with depth south of the' Forelands, and concentrations in the lower Inlet generally vary between 1 and 100 mg/L. REVIEW DRAFT 9/09/Be PAGE 11 In the western Gulf of Alaska from Resurrection Bay thro~gh Shelikof Strait to Unimak Pass, surface suspended solids vary from O.S to 2.0 mg/L in July and August. Values are generally higher to the east near the Kenai Peninsula and Shel1kof Strait. On the shelf east, south, and southeast of Kodiak Island, there is an app.arent absence of any input of suspended sediment. In the Bristol Bay region of the southeastern Bering Sea, streams flowing from the Alaska Peninsula contribute as much as 500 to ~000 mg/L of suspended solids. The dominant sediment sources are the Kvichak and Nushagak Rivers at the head of the bay. The Kuskokwim and Yukon rivers to the north provide sediment input appro~imating 4 and 100 million metric tons per year, respectively, which e~uates to more than 90 percent of all river sediment input into the eastern Bering Sea. Suspe_nded sediment levels for surface waters off the Yukon River and ,in Norton Sound are between 1 and 5 mg/L in July. Surface concentrations generally average between 0.5 and 2.0 mg/L in the northern Bering Sea. Concentrations increase with depth. The near-bottom sediment level from near Cape Romanzof to Nome ranges from 7.5 to greater than 20 mg/L, respectively. Susper•ded range from solids levels in the Berin; Strait and vicinity 1.2 to 4.1 mg/L for surface waters.

North and northeast of the Strait, surface and sub-surface levels increase fourfold to nearly 10 mg/L. Surface water concentrations reach 5.3 mg/L near Point Hope while at depth, only about 1 mg/L is in suspension in July and August. In the northern Chukchi Sea, the suspended load at the surface is low <less than 1 mg/L) and increases with depth. Nearshore loads in suspension are higher than offshore. REVIEW DRAFT 9/09/65 PAGE 12 -· - - - - - - - - - - - - Measurements during twc open-water seasons in the Beaufort Sea demonstrate the inter-annual variability of suspended solids levels. During 1972, inshore surface waters had concent~aticns av&raging 1.0 mg/L with a range of 0.1 to 4.2 mg/Lf however, in the following year, nearly a threefold increase was noted. Levels ranged from 0.5 to 31.0 mg/L and the average was 2.6 mg/L. Except during floods, waters low in suspended matter <about 1.0 mg/L) are commonly discharged in late summer from the maJor distributary mouths, while the presence of relatively turbid waters can be delineated at some distance from the mouths. These observations suggest that in mid-and late-summer, turbidity in coastal waters for the most part is associated with wave-induced resuspension from shallow water regions <U.S. Coast Guard 1972; 1974). 2.3 AQU~TIC ECOLOGY In a bread sense, freshwater ecosystems are divided into two cat,agories, lent ic or standing water systems, and let ic or running water systems. ~ll rivers, lakes, and wetlands support communities of aquatic organisms. ~s such, these communities are interrelated and interdependent, forming networks of distinctly different habitats with respect to flora and fauna, as well as the source of ener;y which drives the biological system. Freshwater aquatic communities derive carbon energy from terrestrial sources <allochthonous organic matter> or through instream <autochthonus) productivity or a combination of these sources.

Salmon favor clear water streams but, in Alaska, often use turbid rivers as migratory corridors. In soma cases, redds are dug in the turbid streams, but the newly hatched fish move to clearer backwater sloughs or tributaries to rear. This is the case with both the Kenai and Susitne rivers.

In addition, the report examines Canadian water quality obJectives for turbidity, supporting rationale, guidelines for setting turbidity and sediment standards, and recommended levels for the protection of a variety of water uses ir. Canada. The ~~g~212~i~--~••!•--!2~--3~•~•ng•g __ 32lig•--g~i1•~!~ by Clarkson et al. (19SS) discusses several factors that are important to the development of a water quality criterion for suspended solids/turbidity for the protection of aquatic biota. These factors include regional, physiographic, and seasonal considerations, and related hydrologic: phenomena. The natural solids loading to a wat.rbody will vary from site to si~e, depending upon physiographic factors (including slope, soil type, and type of ground cover) and upon rainfall and runoff. Hence, seasonal and regional criteria need to be developed that take into account the significance of natural and other nonpoint source loadings. Water quality criteria should be developed for suspended solids in the water column as well as for settled sediment, and these criteria need to address the complex situation of toxics sorbed to suspended and settled solids. Additionally, the effects of sustained exposure to suspended solids versus short-term storm-related pulses need to be quanti- fied. ~lthough the report does not recommend criteria to protect aquatic life, it does establish a framework for consideration of regional, seasonal, and biological factors. 3.3 CANADIAN PROVINCES AND TERRITORIES The Canadian federal government, through the o'f'fices of Environment Canada and the Canadian Council of Resource and Environment Ministers <CCREM>, establishes guidelines and obJectives for water quality parameters for the provinces and REVIEW DRAFT 9/09/SS PAGE 34 - - - - - -i te~ritories.

Fresh water uses include drinking, culinary, and food processing; agriculture; a~uaculture; and industrial. Marine uses include a~uaculture, seafood processing, and indus- trial. The affects of particulates on these various water uses are ~uantified in this section where possible. The extant ~o which suspended solids can be tolerated .in water supplies varies widely. Solids in water used for drinking, culinary, and food processing can support growth of harmful microorganisms and reduce the effectiveness of chlorina- tion, resulting in health hazards. For most water supplies, high levels of suspended solids are obJectionable for aesthetic reasons and can interfere with treatment processes and chemical and biological tests. Suspended solids may also transport nutrients and toxic substances, such as pesticides, herbicides, and certain metals. The amount of particulates allowable in raw water supplies depends on the type and dagraa of treatment used to produce finished water. Sorensen at al. (1977> note that an excellent source of treatment, good source filtration water supply, ra~uiring only disinfection as would have a turbidity range of 0 to 10 units. A of water supply, requiring usual treatment such as and disinfection would have a turbidity range of 10 to 250 units. Waters with turbidities over 250 units are poor sources of water supply ra~uiring special or auxiliary treatment REVIEW DRAFT 91d9/S3 PAGE4~ - - - - - - "'"" ! and disinfection. The ability of common water treatment processes (i.e., coagulation, sedimentation, filtration, and chlorination) to remove suspended matter to achieve water with acceptably low turbidity is a function of the compo~ition of the material as well as its concentration <EPA 1976). The type of plankton, clay, or earth particles, their siz•, and electrical charges, influence coagulation more than the number of turbidity units <NAS 1973>. For eMample, a water with 30 turbidity units may coagulate more rapidly than one with ~ to 10 units and water with 30 turbidity units sometimes may be more difficult to coagulate than water with 100 units <NAS 1973>. Although the Alaska criteria for drin~ing water refer to a ~ NTIJ increase in turbidity above background in raw water, the following information pertaining to turbidity levels ·in finished drinking water is provided to giv• the read•~ a feeling for ~he importance of low turbidity levels. It should be noted that raw wa1;er at a low tl.lrbidity level is the same as finished drinkirq; water with respect to the following information. Sruvold <H~7~>, reporting the results of a consl.lmer acceptance survey of finished tap water conducted by Harris, notes that 11 percent of tho respondents Judged ~ turbidity units to be acceptable for drinking water. This water also had 1~ color units and a tht .. eshold odor nl.lmber of 3. For drinking water, ~ units of turbidity become obJectionable to a considerable number of pec)ple, and many people t~Jrn to alternate Sl.lppl ies which may be letls safe. Symons and Hoff <197:i) discuss the relationship bet: ween particulates in water and the presence of disease- causing organisms. Low levels of particl.llates interfere with d it1infect ion and can prevent maintenance of an affect iva dit.infectant a;ent Ca.;., chlorine) throughout the distribl.ltion syt'.tem. Indic:at ions are that bactaria and viruses can be protected by certain kinds of particles from inactivation by chlorine. Inorganic particles can cal.lse turbidity and probably have no bearfng on tha potential protection of pathogens. Small organic particles, however, may protect pathogens. Therefore, REVIEW DRAFT ~/49/S:; PAGE~l in evaluating water supplies, the nature of the particles in the water should be taken into account. Hence, if only disinfection is applied, the raw water source should be limited to low levels of particulates. George and Lennig (1984> note that a level of 5 turbidity units should not be e)(ceeded for drinking water. EP~ C1976> notes that finished drinking water should have a ma)(imum limit of 1 turbidity unit where the water enters the distribution system. be adversely affected sediments reduces the in many capacity ways. Deposition of suspended of irrigation structures and systems 1'378). and decrease reservoir storage capacity (King et al. . Deposition on land can produce crusts that innibit water infiltration and plant emergence, impedes soil aeration, and car. contribute to salinity problems by hindering -leaching of saUna soils <King et al. 1978>. High colloidal content in water used for sprinkler irrigation may result in deposition of films on leaf surfaces that may reduce photosyntnetic activity and, therefore, growth. The films may also affect marketability of leafy vegetable crops such as lettuce CNAS 1973>. Quality requirements regarding tne amount of particulates vary among different industrial uses. For e)(ample, rayon manufacture requires water with only 0.3 turbidity units, whereas water used for cooling can have up to ~0 turbidity units <McGauhey 1968). Although industrial cooling water can tolerate relatively high levels of suspended solids without significant problems, modern high pressure boilers require water that is virtually free of all impurities <Hach 1983). The quality requirements even vary within some industries, such as the p1.1lp and paper industry. Different processes within this industry require different levels of turbidity. The groundwood process is the least sensitive to particulates and can tolerate up to SO turbidity units, the kraft process up to 2S units, the soda and - - r I sulfite process up to 15 units, &nd light paper production tol•r&tes up to 3 turbidity units <McGauhey 1968>. Crit•ria •stablish•d for evaluating and id•ntifying water treatment n•eds for fish hatch•ries by Sigma Resource Consult&nts <1979) includ• limits on susp•nd•d solids.

Th• guid•lin•s for Canadian REVIEW OR~FT 9/49/83 PAGE4~ recreational· water ~uality <National Health and Welfare 1983) note that the ma~imum limit for turbidity is suggested as 50 turbidity units and the water should be sufficie~tly clear so that a Secchi disk is visible at a minimum of 1.2 meters (4 feet>. These obJectives insure the protection of waters suitable for contact recreation, diving, water skiing, and surfing. including wading, swimming, Fishermen tend not to fish in areas of turbid water because game fishes are not found there in as great abundance as in clear waters <Bartsch 1960). Fishing success is reduced where turbidity is greater than 2~ ppm <Phillips 1971> to 30 JTU <Grundy 1976). According to Townsend (1983), one of the most popular fishing from the recreational activities on the Chatanika River is sport for Arctic grayling. He notes that numerous-complaints public were received about muddy water conditions-in the Chatanika drainage in 1979, the first season of increased placer mining activity in this drainage. Townsend states that fishermen probably refrained from fishing because of turbid conditions. He also notes that in 1977 and 1978 the Chatanika was the second most popular waterbody for sport fishing in the Interior but it fell to seventh place in 1979. Boating, canoeing, and kayaking are enJoyed in ~laska in a variety of clear and turbid systems. There is really no upper limit to the amount of turbidity for these activities. For e)(ampla, river boating (for pleasure and transportation) is popular on the Tanana and Yukon rivers and kayaking and rafting are popular on the Nenana Riverf all are turbid systems. ~ccording to McGauhey <196&>, the noticeable threshold is 20 turbidity units for boating and aesthetic uses but "no level tisJ likely to be found in surface waters CthatJ would impede ttheseJ usetsJ." That is, high turbidity levels do not eliminate boating and aesthetic uses. However, given a choice, most people prefer clear water conditions for these uses. REVIEW DRAFT '?109/8:5 PAGE Iff. ~I ~I -· - - - - 4. ~~. 3 Biota Scientific data describe many ways in which turbidity and excessive concentrations of sediment may adversely affect aquatic organisms. In general, these effects include• (1) Direct actions which either kill or reduce growth rate and resistence to diseaset (2) Prevention of the successful development of eggs and/or larvae, (3) Modification of natural movements and migration, and, (4) Reduction in the abundance of available food items. A substantial amount of information exists ragarcling tne general effects of suspended solids, settleable solids, tu~bidity, and the accumulation-of ~ines in spawning ;ravel on f'rttshwater aquatic organisms. A large percentage of the published literature summarizes the results of investigations undertaken by other authors, and relatively few present original data that quantify the levels which cause deleterious effects. Furthermore, many of the frequently cited publications address the• effects of part ieulates on organisms not found in Alaska waters. Difficulties arise in deriving conclusions about the ef1~eets of part ieulates on speci fie organisms •• a result of the wide range of tolerance among different species, among individuals of different a;•• and stag•• of d•v•lopm•nt, and amcmg individuals of th• sam• sp•eies which have adapted to di1'f•r•nt natural conditions. For example, salmonid egg inc:ubation is advers•ly affected by suspttnd•d sol ids concentrations not: adversely ;rttater than ;r•ater than 3 mg/L, but som• adult salmonids are affected by short-term exposur• to concentrations 100,000 mg/L. Th•r• is a wid• rang• of effects on i ncl i v id•.lals, par•t iculat• their age class, and habitat over a wide range of typas and lev•ls. Furthermore, the various units of REVIEW DRAFT 9119/Se PAGE~? measure and methods of measuring turbidity and suspended matter make it difficult to compare results. Particulates hava direct and indirect effects on aquatic biota. Direct effects include anatomical and physiological influences on the organisms themselves, whereas indirect effects involve impacts al tarat ion. such as a reduction in prey species or habitat ~dditionally, the biological effects of particulates are interactive in that a change in natural levels may affect the structure of an entire aquatic community, as opposed to only one functional group of organisms. Data from early field studies indicate that it is often difficult to assess the effects of suspended solids independent of factors such as sorbed toxic metals and pesticides, biochemi- cal oxygen demand, and nutrient content. -Consequently, ~he obJective of more recent studies has been to identify the biological effects of inert particulate material, similar in size and composition to those found in natural waters. Another problem with early studies is that investigators used a variety of units for turbidity. Hence, there are a variety of units, ppm, mg/L, JTU, FTU, NTU <not directly translated one to another>, making it appear that there are inconsistencies in tha reported data. The actual units reported in the literature appear in the following discussion of the affects of particulates on biota. Particulates, especially turbidity, are considered to have a deleterious effect on plant communities within waterbodies. Few quantitative results are reported in the literature. Bell <1973> reported that algal-based food production for JUvenile •almonids was reduced at turbidities above 2~ JTU. In Sraat Britain, Nuttall and Bilby (1973) stated that rooted aquatic ve!iletation was exceeded 2000 Read et al. absent at stations where suspended solids levels ppm in a river polluted with china-clay wastes.

Sedimer~t which settled out caused a reduction of 40 percent in population density regardless of susper~ded sediment concentration. Invertebrate drift increased immediately when introductions of 160 mg/L sediment were made to the stream. Wilber <1983>, citing Herbert et al. <1961>, reported that mac1rooinvertebrate populations are reduced at turbidity levels of S:61 to 390 ppm ar~d that der~sity is reduced at 1000 to 6000 ppm. Red,Jced numbers were reported for turbidities of 40 to 200 JTU <Sorensen et al. 1977).

NCASI (19S4b) conducted a literature review pertaining to the effects of sediments on salmon habitat. It was discovered that the time necessary for coho fry_ to emerge from the gravel in. wh-ich. they were hatched increased from 10 to 47 d·ays when the amount.·of fines <less than 3.327 mm in diameter> was increased from 36.6 to 42.3 percent <Koski 1966>. sediment levels increased from 27 to 51 percent. Coho biomass decreased 65 percent when sediment smaller than o.e mm increased from 20 to 31 percent as a result of road construction <Burns 1972). Juvenile coho productivity was reduced from 8.8 grams per square meter to 5.0 grams per square meter as sediment embeddedness was increased from 0 to 100 percent in a laboratory stream <Crouse at al. 1961; NC~SI 1964a).

At S':J,spended sediment concentrations of 3 to 1810 mgiL, where the permeability was 7 to 2950. cm/hr and dissolved O)(ygen-was 3.8 to e.G mg/L, survival of the eggs ranged from 24 to 98 percent. Witzel and MacCrimmon ( 19Si1 > found that only 1 percent of the rainbow eggs survived when the gravel was 2 mm in diameter but that 76 percent survival was achieved when the gravel diameter was 26.5 mm. The main concern with regard to the protection of aquatic fauna from lethal sediment concentrations is the amount of solids in suspension that can potentially settle out <settleable solids> as flow decreases <Duckrow and Everhart 1971>. It is the sessile, immobile forms in or on the streambed which are the most susceptible to being smothered. Sedimentation of the str•am substrate, particularly the gravel used for spawning, produces significant detrimental effects on salmonid resources <Iwamoto et al. 1978). Iwamoto et al. <1978) note th.at there are subst.anti.al data describing the deleterious effects of p.articles of si:es less than 0.850 mm in diameter when they e)(ceed approMimately 20 percent of the ·total. They also note that sediments ranging between 0.1 and 3.3 mm appear to cause the most significant impact. REVIEW DRAFT lf/49/95 PAGE SS Sediment deposited on the streambed sur~ace or within the gravel can reduce the gravel <Cooper and direction of the exchange of water between the stream and 1965>. Three factors affect ~he magnitude water interchange in spawning beds: (1) The surface profile of the streambed; (2) depth of the streambed; and <3> streambed permeability. Water exchange occurs in stream gravels as either downwelling or upwelling. Downwelling is predominant in convex streambed surfaces, whereas upwelling occurs where the streambed is concave. Furthermore, increased stream gravel permeability induces downwelling, whereas decreased permeability induces upwelling <Vaux 1968>. Substantial reductions in flow through the gravel may result from a reduction in the size of particles in the gravel bad <Cooper 196~>. Permeability may be increased by removing fine material from the stream gravels CMcNeil and ~hnell.1964> such as during flood events that wash fines out ofi the gravel. The intrusion of fines into •tream ;ravels is a complicated and not fully understood process <Beschta and Jackson 1979>. Presently there is little known about the mechanisms and rates of sediment interchange between the water column and the inter- stitial environment <Carling 1984>. Sediment intrusion involves the transport and deposition of particles into gravel voids at the surface, and the settling of particles into deeper gravel voids under the influence of gravity, assisted by turbulent pulses at the gravel surface <Beschta and Jackson 1979>. Since there is o~ten an exchange of flow between a stream and the gravel bed of a stream, it is logical to expect that suspended sediments might be carried into the gravel and deposited even if they are not deposited on the streambed. While conducting bedload experiments with gravel, Einstein <1968> noticed that murky water gradually cleared up at low bedload rates, and postulated that the deposition of suspended silt particles must occur in the pores o~ the gravel bed. Subse~uent experiments showed that the depo~ition rate of suspended silt particles begin to fill the pores of the ;ravel ~rom the bottom up. The concentration of silt ranging from 3.~ to 30 microns decre~sed REVIEW DRAFT 9/G9/S:i PAGE Si - - - - - .... r exponentially. downstream as sediment was deposited in the stream gravels. As a result of these experiments, Einstein (1'368> concluded that the deposition of silt is primarily a function of the sediment concentration close to the sediment-watlfr interface and that hydraulic controls are of secondary importance. Carling <1'364) notes a similar experiment in which low concen- trations of silty clay <less than 300 mg/L) decreased exponentially downstream although high concentrations decreased logarithmically. A series of experiments conducted by Beschta and Jackson (1'379> demonstrate that flow conditions, as indexed by Froude numbers, significantly influenced the degree of gravel intrusion by sand. Other flow indicators such as shear velocity and Reynold's number did not significantly affect the amount of intrUsion. At low F~oud~ numbers, 0.~ mm sand quick~~ established a sand "seal" withir'l the upper :5 ern of the gravel. Or'lce the sar'ld seal had formed and the intergravel spaces had filled with fines, the downward movern•nt of additior'lal sediment was prevented ar'ld the ir'ltrusion process stopped. In comparison with 0.:5 mm sand, the intrusior'! of 0.2 mm sand was more extensive suggestir'lg that particle size is an important variable affecting the intrusior'l of stable gravels. Instead of forming a sand seal in the upper gravels, the finer sands generally migrated dowr'l through the test gravels by gravity ar'!d began to fill tnem from the bottom up. The amour'!t of ir'ltl"'usion of 0.2 mm sand decreased as the Frouda r'!umber increased from 0.6 to 1. 1. These observatior'ls support the findings of Einsteir'l <1'368> that intrusior'l by fine sediments fills stream gravels from the bottom up. !Ex;~eriments were cor'!duc:ted by Cooper <1963) using 0. 5 to 74 micron silt in concentrations of 200 ar'ld 2000 ppm to determine the rate ar'!d magr'litude of fine sediment deposition. Data show that stream gravels act as a filter il"1 removir•Q SI..ISpended sediments from the water flowing through the gravel. The rate REVIEW DRAFT 910'3/85 PAGE5'7 of silt accumulation in the gravel varied in proportion to the flow through the gravel. Carling (1984) found that porous gravels could physically entrap particles in the dead zones on the lee side of gravel grains and prevent resuspension. In base level flow conditions an.d low concentrations of sediment, the grain size of particles settling onto the gravel bed is similar to particles filling the gravel void spaces. For all concentrations, the deposition rate was strongly linearly correlated with the suspended sediment concentration. Results indicate that open-work gravels will rapidly become silted even with water containing low concentra- tions of suspended solids. Thus, the amount of silt and. larger particles trans~orted in suspension may have a pronounced affect on the natural qual~ty and composition of gravel substrates in streams. However, McNeil and ~hnell <1964) report that fines in the gravel can be locally removed by salmon during spawning. Nevertheless, additional sediment deposition and infiltration after spawning may reduce the rate and magnitude of water eMchange in spawning gravels, to the detriment of developing eggs. ~lthough particles in of clay-sized embedded ness this proJect. it is well documented that silt .and larger suspension may fill streambed gravels, the effects and other non-settleable particles on streambed are not reported in the literature reviewed for In summary, numerous field and laboratory investigations have documented lethal and sub-lethal effects of suspended and deposited sediments on freshwater aquatic organisms. These effects are summarized in Tables 4-1 through 4-4. Most of the numerical data appearing in these tables pertain to salmonids and their t•Jrbidity habitat.

Ft.~rthermore, quantit&tive analyses nave been to determine the effects of sediment on feeding, growth, prodtJctivity, biomass, and behavior. Nonetheless, a abundance, anatomy~ physiology, number of data g&ps exist with regard to threshold levels having a specific effect on a particular species. The above discussion demonstrates that particulates have detrimental effects on freshwater aquatic biota. (1) Turbidity reduces the •mount of light available for green pl&nt growth and photosynthesis within water bodies, can inhibit instream movements of fish, and may inhibit the &bility of fish to see their prey. <~> Turbidity and sett1ed solids can cause reductions in invertebrate populations and can cause an increase in invertebrate drift. <3> Ability of fish to withstand various concentrations of settled and/or suspended solids depends on their life stage. Adult fish can withstand relatively high concen- trations of suspended solids for limited amounts of time without suffering mortality, although other physiologi- cal effects such as fin and ;ill damage and stress reactions may result. C4> Survival of fish eggs and JUVeniles may be significantly reduced by settled solids in spawning and rearing areas. <S> Settled solids have direct effects on aquatic biota and habitat by smothering fish eggs, alevins, and inverte- brates, reducing intergravel flow, and by coating aquatic vegetation, thus reducing the potential for photosynthesis. <6> Solids in suspension can cause invertebrate drift, cause fish to avoid previously usable habitat, prevent fish from seeing their prey, and cause physical damage, such as gill irritation, to fish. REVIEW DRAFT ~/QS/85 PAGE'~ .~. - - I"'"' - - (7) Silt ~nd larger particles in the water column can fill open-work gravels •ven when the concentration of suspended solids in the water is low. The biological effects of inorganic suspended solids on marine communities are complex and extremely difficult to quantify. The effects on zooplankton and higher aquatic organisms are more difficult to evaluate than the effects on phytoplankton <:Brehmer 1965). With the exception of a few commercially important species, little is known about the effects of turbidity and suspended material on marine i r1vert ebratas <Stern and Stickle 1978). Different species of marine organisms are affected to different degrees by the same concentrations of turbidity~causing sediments <Loosanoff 196~i Moor~e 1977; McFarland and Peddicord 1 980). Many species of -marine ~hellfish and finfish are sensitiv• to increases in suspended solids, which undoubtedly have an inJurious effect on the estuarine community as a whole <Brehmer 1965). Filter feeders and early-life stages of estuarine fish are more sensitive to suspended sediments than bottom dwelling organisms and adult fish <Sherk et al. 1973). As filter feeders, bivalves are particularly susceptible to the mechanical or abrasive action of suspended sediments <Cairns 1967; Moore 1977). Other filt•r-feeding invertebrates at risk from inorganic suspensions include mollusks, certain crustaceans, sponges, ascidians, and E!metl.!.2!i~! (Moore 1977). The effects of particulates on marine biota are divided into discussions of plankton, egg development and hatching success, larva• survival and development, and adult survival. This is followed by a discussion of feeding and growth and finally distribution. REVIEW DRAFT 9/QS/85 PAGE6S Carbon assimilation rates by four species of phytoplankton were si;nificantly reduced by the light attenuating properties of fine silicon dioxide suspensions. A concentration of 1000 mg/L caused a ~0 to 90 percent reduction in carbon uptake among the four species tasted. A concentration of asoo mg/~ caused an eo percent reduction in one of the species tested <Sherk et al. 1 S7G>. The presence of an open-ocean turbidity plume in the North Equatorial Pacific, havin; an average suspended sediment concen- tration of 440 ug/L, reduced primary productivity by 40 percent over the entire euphotic zone. However, because particulate concentrations return to ambient within a few days, it is believed that <Ozt urgut et speci•s composition changes would not take place al. 1981). The results of two sets ~f plankton tows indicated there was no maJor.de~rease in the abun~ance~of neustonic macrozooplankton or sufficient amounts of particulates ingested to cause alteration in their chemical composition at turbidity concentrations of less than 1 mg/L. The relationship between gastropod eggs and suspended solids concentrations is discussed in a literature review by Stern and Stickle C197S). One species of planorbid snail showed normal egg development at 190 to 3&0 ppm, while another species experienced high mortality at the same concentrations. A third species did not lay eggs in the 360 ppm water but did so in water containing 190 ppm suspended solids. Loosanoff and Davis <1963) report that silt is considerably more harmful to oyster e;;s than to clam eggs. at concentrations of 2~0 mg/L silt, only 73 percent of oyster eggs survived, while more than 9~ percent of clam eggs developed normally. Practically all clam eggs developed in concentrations of 500 mg/~ silt, while only 31 percent of oyster eggs survived. In a 1000 mg/L suspension of kaolin and Fuller's earth, on the other hand, practically all oyster aggs developed normally, REVIEW DRAFT C1 /~9/SS PAGE hh - - - llllm!o.• - - - ~·, .~ - - - while showed eggs earth only 37 to that the decreased increased 57 percent of clam eggs survived. Davis <1'360) normal development of clam CY~n~§ m~rs~n~r1~l as concentrations of clay, chalk, and Fuller's up to 4000 mg/L. The same was ~~ue for silt concentrations exceeding 750 mg/L. Furthermore, no clam eggs developed normally in silt concentrations of 3000 or 4000 mg/L. In a subsequent paper, Davis and Hidu <1'369>, report that 188 mg/L silt, 3000 mg/L kaolin, or 4000 mg/L Fuller's earth significantly reduced the normal development of American oyster eggs. Oyster eggs were not, however, affected by 4000 mg/L silicon dioxide, . regardless of the particle size. These findings suggest that the composition, as well as the concentra- tion of different sediments may be critical to the normal development of bivalve eggs. Auld and. Sch•Jbel ( 1 '376> note that suspe-nded sediment concen- trations up to 1000 mg/L did not significantly affect the hatching success of a variety of non-salmonid anadromous and estt.Larine fish. The same concentrations did, however, reduce the hatching success of white perch and striped bass. Kiorboe et al. <1'381) report that herring eggs are unaffected by s•Jspended silt. They note that the embryonic development of herring is unaffected by either short-term exposure to 500 mg/L, or long-term exposure to 5 to 300 mg/L suspended silt. With respect to larval survival and development, experimental results indicate that suspended sediment concentra- tions of 500 mg/L significantly reduced the survival of striped bass and white perch larvae, whereas short-term exp9sure to 100 mg/L reduced the survival of American shad larvae CAuld and Schubel 1'378). As in the case of clam and oyster eggs, Loo:sanoff and Davis ( 1'363) found silt to be more harmful to oyster larvae than to clam larvae. At a concentration of 750 mg/1_ silt, oyster larvae growth was markedly decreased, while clam larvae grew normally in 1000 mg/L silt. Moreover, clam larvae survived for 1i2 days in 3000 to 4000 mg/L silt. In REVIEW DRAFT 9/0'3/85 PAGE lt7 contrast to si 1 t, 1000 mg/L kaolin caused total mortality in clam larvae in 12 days, while the growth of oyster larvae was not affected by 1000 mg/L kaolin. Silicon dioxide particles ranging from S to 50 microns had little effect o~·the survival of either pert icles clam or American oyster larvae. The smallest <<5 microns> had the greatest affect on the larvae of both species. Growth of American oyster larvae decreased progressively as the size of silicon dioxide particles decreased <Davis and Hidu 1969>. From these studies, it was concluded that bivalve larvae grew faster in low concentrations of suspended solids than in clear sea water <Davis and Hidu 1969). With respect to adult survival, McFarland and Peddicord (19S0) observed a wide range of sensitivities to suspended kaolin among the 16 marine species they studied. Eight species exhibit•d lass than 10 percent mortality aft•r exposure to ~00 g/L suspended sediment. Several other species were found to be rnore sens it i ve. was 96 giL. Two species of tunicates we~e relatively tolerant of suspended solids with a 12-day LC~O of 100 giL. The 200-hr LCSO for the spot-tailed sand shrimp was ~0 g/L. The 400-hr LC30 for the same species was 40 giL indicating a high tolerance to suspended clay. The euryhaline grass shrimp was even less sensitive to suspended kaolin. The Oungeness crab, ~Ans~r m~a1§t@~, was found to be more sensitive than any of the shrimp species, with a 200-hr LC50 of 32 giL. The amphipod, 8n1~2QA!!!!!l!.~Y~ sensitivity to £2Df•c~i~2!Y•• demonstrated an intermediate suspended sediment with a 100-hr LCSO of 78 g/L. The kaolin concentration which caused SO percent mortality in the polychaete Er•gl ish sole, 10 days at a percent mortality occurred after 10 days at 117 giL. The shiner perch, ~.!. §~.;r•.;§1.!h was the most sensitive sp•cies tested with only one fish alive after 26 hotirs i~ 14 g/L suspe~ded kaolin <McFarland and Peddiccrd 1960). In a similar publication, REVIEW DRRFT <J /09/65 PAGE "8 - - - - - - - - Peddicord <1980> states that marine and estuarine invertebrates were able to tolerate continuous exposure to suspensions of kaolin and bentonite in the grams/liter range for several days to several weeks without substantial mortality. Fi~h tolerated similar concentrations for similar periods under similar conc:l it ions. Even at high temperatures and low dissolved oxygen concentrations, most invertebrates tolerated continuous exposure to 60 g/L suspended bentonite for several days before mortality occurred. An exception is noted for JUVenile Dungeness crabs which were affected to a greater degree by kaolin suspensions than other species. Moore <1977) notes an experiment in which shrimp <gr~!!.EI.2!! sp.> survived immersion for 14 days in a clay suspension of 3000 mg/L.. In another experiment, grs!!.EI2!! sr~!!.EI.2!! survived red mud suspensions up to 33 g/L for 72 hours, but were heavily coated on the gills.

Adult bivalves <Br.EI2Q§SI~!! 1rrs912!!~> also showed higher respiration rates at ~00 and 1000 mg/L kaolin.

Furthermore, they note that scallop and quah1og <clam> reproduction may be impaired by high concentrations of suspended solids. Pedd ic:ord et al. < 197~> note several investigations in which deposited sediments increased the mortality rate of bottom dwelling marina invertebrates. Oysters <gr•~~Q3Ir§2 ~ira1niss> suffered ~7 percent mortality where they were covered with 2 to 15 em of sediment near a dredge spoil site. This compared to 17 percent mortality in the same oyster bed where little sedimentation had occurred. Cumaceans and harpacticoid c:opeoods were killed by deposition of 15 em of sediment. The same amount of deposition reduced the number of large bivalves by 50 percent.· In experiments conducted by Peddic:c•rd at al. < 1'375>, REVIEW DRAFT 9/119/85 PAGE"" the rnc•rt ali ty 60 percent of mussels C~L §lMll~> was 10 percent under 4 em under 6 and 8 em of sediment deposited on the Static bioassays conducted by Sherk et al. <1'375> established the lethal concentration of Fuller's earth on a variety of non-salmonid estuarine fish. Species were classified as tolerant 010 g/L), sensitive <1.0 to 10 g/L), or highly sensitive <<1.0 giL.>, based on a ~4-hour L.C10. Lethal concentrations ranged from O.~a to 24.~ giL., depending on the species. E~posure to sublethal concentrations of Fuller's earth significantly increased the hematocrit value, hemoglobin concen- tration, and erythrocyte numbers among the species tested. With ( 1 '380) levels respect to feeding and growth, Johnston and Wildish conducted an lnvestigation to determine if increa~~d of suspended sediment reduced the feeding rate of larval herring. the same However, Larvae fed in water containing 4 and a mg/L. consumed quantity of zooplankters as those fed in clear water. larvae fed at 20 mg/L consumed significantly fewer zoo- plankters than did the controls.

At greater suspended sediment concentrations (20 mg/L), light intensity and visibility of prey are reduced sufficiently to cause depressed feeding rat••· Brehmer <196~) reports that the feeding activity· of certain filter-feeding shellfish is ir·1hibited by high suspended solids levels. At"t &K&mple is noted by Moore <1977) in which the filtration rate of a mollusk <~r-~1gY1A sp.) was significantly reduced as turbidity increased from 140 to 200 mg/L. Likewise, Johnson <1971) found that the filtration rates of ~. fQ~nl~&t~ decreased as natural suspended solids levels increased from 2 to 250 mg/L. Ha also found that the filtration rate decreased significantly as the concentration of silt, Fuller's earth, and kaolin was increased up to 6 g/L under experimental conditions. It is interesting to note the REVIEW DRAFT q;Q3/85 PAGE 70 - - - - l/lliil)l - - - ..... - difference between natural and e~perimental sediment concentrations which produced the same reported effect.

In contrast, Stern and Stickle <1978) cite a report which states that oyster feeding rates were not impaired by 100 to 700 ppm of suspended mud. The ingestion rate of two calanoid copepods was significantly reduced during exposure to a 2~0 mg/L mixture of Fuller's earth, fine silicon dioxide, and river silt <Sherk et al. 197~; 1976>. At a concentration of 300 mg/L river silt, the ingestion rate was reduced by 77.3 percent <Sherk et al. 1976>. The distribution of marine organisms may be affected by turbid conditions.

Several anadromous salmonid investigations perfo~med in fresh water are cited in the marine literature. The results of such studies apply to both fresh water and marine systems and are presented above in Tables 4-1 through 4-4. The quantitative effects of suspended solids and turbidity on marine plankton and macroinvertebrates are summari:ed in Tables 4-5 and 4-6. The above discussion demonstrates that particulates may_ have detrimental . effects on marina biota. These effects ~re summarized below. <1> The biological affects of particulates on marine biota are similar to the affects on freshwatar aquatic biota. Particulates in the water column reduce the amount of light availabla for photosynthasis, can inhibit move- ments of fish, and may inhibit the ability of fish and other sight-feeders to sae their prey. Filter feeders, which are p&rticularly susceptible to the mechanical or abrasive action of suspandad sadimants, and early-life stages of astuarina fish are more sensitive to suspended sadimants than bottom dwalling organisms and adult fish. <2> Much of the marine literatura refers to the effects caused by clay, silt, chalk, Fullar's aarth, and kaolin.

This section presents these suggested criteria. It should be noted that there is general agreement on the criteria for water supply and recreation, aquatic biota are varied. but the criteria for the protection of 4.3. 1 Water Supply For drinking water, ··the raw water source should be limi1;ed to 5 turbidity units if only disinfection is applied <George and Lehnig 1984>. Higher levels of particulates are acceptable if the source water is adequately treated <coagulation, sedimentation, prior to chlorination or other means of disinfection. EPA C1976) notes that finished drinking water should have a maximum limit of 1 turbidity unit where the water enters the distribution system. The water quality criteria for particulates varies amor-1g industrial uses. At one extreme, rayon manufacture requires water with only 0.3 turbidity units, whereas water used for cooling can have l.lp to ~0 turbidity units CMcGauhey 1 968>. Other industrial uses require maximum turbidity levels within this range. Criteria established for evaluating and identifying water treatment Consultants needs ( 1 979) for fish include hatcheries by Sigma Resource limits on suspended solids. The suggested limit for sr.tspended solids for incubating eggs is 3 REVIEW DRAFT CfiQ9/S~ PAGE 'Tw - - - ~ -· ~ - - - - - - - - - rtJt!L. and for rearing and holding the limit is 25 mg/L in the absence of other pollutants. 4.3.2 Recreation The noticeable turbidity units, <Mc6auhey 1968>. threshold for water contact recreation is 10 and the limiting threshold is 50 units Tha suggested maximum turbidity limit for Cana1dian contact recreational water quality is 50 turbidity units and the minimum Secchi disk visibility depth is 1.2 meters <National Health and Welfare 1983>. Fishing success is reduced whar·e turbidity is greater than 23 <Phillips 1971) to 30 NTU <Grundy 197S>. According to McGauhey (1968>, the noticeable threshold for boating and aesthetic uses is 20 turbidity units. However, there is no evidence that boating and aesthetic uses are precluded at higher t~rbiditias. 4. 3. 3 Biota Sugestad particulates criteria from the literature are divided into two categories in the following discussion: <1> Criteria for sediment in the water column <suspended solids and turbidity)f and, <2> Criteria for sediment deposited on the substrata <settleable solids and substrate measurements>. by aqu•.t ic SUQ!;i&Sted m1aters surf' ace. suspended sadim•nt criteria were initially proposed (1937; 1944) with respect to light penetration and life. For the restoration of streams, Ellis (1937) th• silt load should not reduce the light intensity at by mora than one millionth of its intensity at the Ellis (1944) restated this criterion for the prevention of direct damage to the gills and delicate exposed structures of fish, mollusks, and insects. For the protection of fish, Berger (1977> suggests that turbidity shall not average REVIEW DRAFT q/49/83 PAGE7~ more than 27 times the natural level during any a-hour period, or more than 9 times the natural level during any 96-hour period, or more than 3 times the natural level during any 30-day period. These suspended sediment standards shall apply during and for 2 years after they have ceased. turbidity and macroinvertebrates during period were stated as follows. In the construction activities Berger's criteria for the post-construction year that starts 12 m~nths after completion of a construction should not exceed one-half of the levels and the Shannon Diversity Index for macroinvertebrates shall not be changed from the natural value as a result of activity, recommended t•..lrbidity above bottom-living aquatic more than as percent finely-divided solids. The first definite suspended solids criteria for ·fresh water were proposed by the European Inland Fisheries Advis~ry Commission CEIFAC> ln 1965. According to the commission, there is no evidence that suspended solids levels less than 25 ppm have any harmful effects on fish; suspended sol ids ir• the range of 25 to 80 ppm will maintain good to moderate fisheries; eo to 400 ppm suspended sol ids are unlikely to support good freshwater fisheries; and, at best only poor fisheries are present in waters containing greater than 400 ppm suspended solids. These tentative criteria proposed by EIFAC were based on a survey of existing literature, and were presented as a basis for discussions of criteria necessary for the maintenance of freshwater fish. They are by far the most frequently cited criteria. Not all authors, however, indicate if they simply concur with the criteria suggested by EIFAC or are suggesting identical criteria based on conclusions derived independently. Those who suggest or state criteria similar to EIFAC include Gammon <1970>, Alabaster (1972), Bell <1973>, NAS (1973>, Sorensen et al. (1~77>, Alabaster and Lloyd <19Sa>, Wilber <1SS3>, and George and Lehnig (1984>. In addition, Van Nieuwenhuyse <1983> and Simmo~s <1984> suggest turbidity criteria levels <NTU> similar to the EIFAC criteria for suspended solids Cppm>.

In their_ review of the EPI=I Red Book, Thurston et al. <1979> support a limit of 100 mg/L of suspended solids to prevent the mortality of fresh and marine organisms. However, one of the r·evtewet•s felt that 100 mg/L is too restrictive and t-hat concen- trations could be much higher without causing adverse effects. These values are higher than those suggested by EIFI=IC (1965) to r11a i rlt a in effetcts a good fishery, but do not account for the sublethal discussed by several authors and presented in this 1 it e1rat ure review. Thurston et al.

(1979) regarding lethal universal agreement allowed. ~erbert fairly distinct cont:aining fish recc)mmandat ion conc:entrat ions. The most conservative recommended turbidity standard is 25 NTU above natural conditions in streams and ~ NTU above natural conditions in lakes for moderate protection, and 5 NTU in both lakes and streams for a high level of protection <Lloyd 1985). With regard to incubating eggs, Sigma Resource Consultants <1979) propose an acceptable limit of 3 mg/L suspended solids and 25 mg/L would be acceptable for fish rearing and holding in the absence of other pollutants. OFO <1983> has proposed sediment discharge standards, as opposed to receiving water standards, for five different classes of streams. For streams which are important as salmon and trout spawning habitat (1=1 classifications>, the recommended sediment standard is 0 m;/L. Streams which are rearing areas for salmon and trout <B crassifications> and those which provide habitat for grayling, whitefish, and burbot <C classifications> would have a discharge limit of 100 mg/L. In streams having low or no use by any of the above fish except as migration routes, the recommended standard is 100 or 1000 mg/L. The same is true for all streams having a reduced biological capacity due to past placer min1ng activities <X classification). REVIEW ORI=IFT q;~9/8~ PI=IGE 79 Sherk. et al. <1975) state that the use of lethal concel"rtra- tions <LC30) to establish suspended solids criteria ignores biologically significant sublethal effects on estuarine organisms. Therefore, in establishing criteria for the protection of estuarine organisms, the sublethal effects of suspended sediment on the most sensitive biological cofl1pol"lel"lts <important species and life stages> must be considered. Adequate knowledge of local conditions, such as life-history stages, sediment types, sediment concentrations, species, duration of e~posure, and habitat preference, is required. Tarzwell ( 19~7) numerical criteria states that it is not possible to establish for settleable solids which are applicable over wide areas. The criteria should be established to protect environmental conditions but will vary from stream to stream, depending on local concditions. With regard to deposited sediment, EIF~C <196S> concluded that spawning grounds for salmon and trout should be l<ept as free as possible from finely divided solids. BJornl"l et al. (1974) suggested that the amount of sediments that should be allowed to enter a stream before detrimental effects will occur on the aquatic habitat will depend on the amount of fines already contained within the stream channel. The amount that can enter the stream is the difference between the present level and the allowable, plus the amount transported. BJornn et al. <1977> state that fine sediment should not be allowed to fill pools or fully embed the larger substrate rocl<s, to avoid reducing the salmonid production capacity. They advocate using the percentage of fine sediment in selected riffle areas as the primary inde~ for monitoring fine sediment deposition in streams. Along these sarne lines, I~amoto et al. <1'378> indicate that the best alternative appears to ba the establishment of criteria which limits the percentage of fines i~ the streambed, and suggest a limit of 10 to ZO percent for sediment less than 0.95 mm in REVIEW PR~FT q;Q9/S~ P~GE So - - - - - - - ~- - diameter. 1n an earlier report, Ellis (1944) thought that fine sediment should be controlled to the extent that it does not blanket the bottom to a depth of more than one-quarter of an inch. Van Nieuwenhuyse ( 1 '383) and Simmons (1'384) propose a settleable solids standard of <0.1 ml/L for a high level of protection in receiving waters. Simmons (1984) goes a step further and suggests settleable solids levels of 0.1 to 0.2 ml/L for a moderate level, protection. and )0.2 ml/L for a low level of 4.4 REFERENCES ADEC, 1985.

REVIEW DRAFT 9/09/85 PAGE 89 -5.0 POTENTIAL USE OF OTHER PARAMETERS This section presents a discussion of potential alternatives to the parameters c::urrer.tly used by Alaska -for defirdng particulates criteria for tha various protected water uses. Parameters currently employed include turbidity, total suspended solids, settleable solids, and the percentage accumulation of fine particles in the substrate. This discussion is divi~ed into water column measurements and substrate measurements. The settleable solids test, although a water column measurement, is discussed frequently with substrate measurements because settleable solids become part of the substrate. A discussion of the between turbidity and suspended solids appears r•el at i onsh i p before the of' water column and substrate 5. 1 RELATIONSHIP BETWEEN TURBIDITY AND SUSPENDED SOLIDS The accepted technique for measuring suspended solids <APHA 1985) is time consuming, costly, and normally performed in a laboratory. Due to these constraints, many field investigators have used turbidity as an indirect measurement of the concentra- tton of suspended solids. In order to adequately assess the potential for a relationship, if one exists, one must understand the principles of turbidity and suspended solids measurement, be familiar with the various methods of measurement and analysis, an~ be awar• of the potential variability inherent in each of these methods. In the simple terms, turbidity may be interpreted as a measure relative clarity of water <Hach et al. 1984). However, t~rbidity is not •• precisely defi~ed as dissolved oxygen, pH, alkalinity or many other water quality parameters. It must be recognized that turbidity, like color, is a visual or optical property. Consequently, the word means different things to different people. Pickering <1976> notes that turbidity should REVIEW DRAFT 3/03/25 P~GE qo -I - - ~' ~- .~ - r II i be treated as a non-quantitative term similar to the term "wa1rmtn," in the respect that one measures temperat1.1re and not warmth. With respect to measuring particulates, turbidity has received the most attention. Some water quality experts believe that the turbidity measurement is subJect to great uncertainty and variability as a unit of measurement. This belief primarily originates from a number of studies related to placer mining where exceedingly high levels of turbidity have been measured. Turbidity measurements are less precise at high levels. Attempts to quantify turbidity have led to the development of methods, instruments, standards, and units of measure. Consequently, there is a gr~at deal of c:onfus~on over whi1:h methods, instrument's, standards, and units of measure are the most appropriate. McCluney C1975) has summarized the various definitions of turbidity. These include tha intensity of light transmitted (unscattered) through the sample, ratio of the intensity of light scattered by a sample to the intensity of the light source, the amount of light scattered and absorbed rather than transmitted in straight lines through the sample, and a reduction in transparency of a sample due to the presence of particulate matter. Turbidity has also been defined as the amount of suspended matter, in ppm, as ascertained by optical observation, and in terms of different measurement techniques <e.g., Jackson Candle and nephelometric: turbidity>. The units of measure for turbidity have included mg/L, ppm, Jackson turl::~idity units CJTU), formazin turbidity units <FTU>, and nephelometric: turbidity units <NTU>. Because of the variety of different methods, instruments, standards, and units of measure, many of the supposed equivalent measurements presented in the literature are actually expressions of different properties of nat1.1ral water (McCarthy et al. 1974). Today, however~, mos·~ investigators use nephelometers and report results in NTU rather than the older units. Hence, recent data are more comparable. REVIEW DRAFT 9/09/65 PAGE q1 Comparability of turbidity measurements may not only be affected by the numerous ways of measuring it, but may also be influenced by the variability among instruments <Beschta 1980>. Even among nephelometers, there is a variety 6f different physical designs. This situation makes it difficult to compare turbidity levels. Even using the same standard suspension for calibrating different instruments does not insure that turbidity values will be the same. Pickering (1976) reports that different types of instruments were calibrated with the same formazin standard and then used to measure various natural water samples. This resulted in a variety of turbidity values for the san1e sample. The only means for reducing the confusion surrounding turbidity measurements is to standardize the definition of turbidity and th~ instrum~nt design specifications. This has been accomplished according to §t~OQ~~g-~~t~2Q~ <APHA 1985) and _. the EPR < 1983} methods mar.ual. §t9'0Q~~Q_M!!th2Q§ is JOintly published by the American Water Works Association, a drinking water group, the Water Pollution Control Federation, a waste and sewage group, and the American Public Health Association, a public health group. The EPA methods manual is used by many among these groups as well as scientists interested in streams, lakes, wetlands, estuaries, and coastal areas. Hence, much of the confusion could, and should, be avoided by adhering to the definition of turbidity and instrument design specified by APHA ( 1985) • APHA <1985) defines turbidity as an expression of the optical property that causes light to be scattered and absorbed rather than transmitted in straight lines through the samples. Turbidity in water is caused by suspended matter, such as clay, silt, finely divided organic and inorganic matter, soluble colored organic compounds, and plankton and other micro$COpic REVIEW DRAFT 9/09/SS PAGE q~ - - - - - - - - - r_ - According_ to APHA (1985), the standard instrument for measuring low turbidities is the nephelometer, for which a formazin polymer is used as the standard reference suspension. The light source is a tungsten-filament lamp operated at a color temperature between a,aoo and 3,000 K, where the angle of light acceptance by the detector is 90 degrees plus or minus 30 degrees. The distance traversed by incident light and scattered light with1n the sample tube is not to exceed 10 em. Turbidity measurements less than 40 NTU can be read directly from the instrument. Turbidities above 40 NTU need to be diluted with turbidity-free water until turbidity falls between 30 and 40 NTU. The precision and accuracy of nephelometric turbidity measurements are highest at lower levels, the leve1s at which c:r•it:eria are currently set. This s_tatament is supported by t':'e proper reporting of significant figures according to APHA ( 19E~5) , which is: Turbidity R.-nge _____ t:iiY ______ _ 0-1.0 1-10 10-40 40-100 100-400 400-1000 >1000 Report to the _t:i!Ult:t!.t_t:iiY_ 0.0!5 o. 1 1 3 10 30 100 There are fewer direct methods for measuring total suspended solids than there are for turbidity. Hance, there is less variability in suspend•d solids determinations. Total suspended solids represent the m•terial retained on a standard glass-fiber filter after a well-mixed sample is filtered, then dried at 1<)3 to 103 degrees C <APHA 1985). Some investigators have inappropriately used 0.45 micron filters. Some marine scientists have used centrifugation for concentrating suspended REVIEW DRAFT 9/09/83 PAGE q3 particulates-followed by drying and weighing.

Hence, some investigators obtain composite samples ove~~i~e-by manually collecting grao samples acl"'os~ a cross-section or.by the use of automatic samplers. Automatic samplers, however, are usually set to sample only one location at a cross-section and may not collect all particle sizes. Composite samples can be time-weighted by combining equal volumes of individual samples at a specified time interval, or discharge-weighted where the volume of each individual sample is proportional to the stream discharge, Each type of composite can result in different report~d particulates levels. The difficulty in obtaining representative and reliable particulates data from automatic samplers has been documented for municipal wastewater treatment plants. Reed <1977) reported the results of Harris and Keffer who note that the suspended solids data for a raw municipal wastewater treatme~t stream, rnonitored conc•Jrrently with more than one commercial automatic: sampler, can vary by as muc~ as 300 percent depending on the type of automatic sampler used, The most reliable suspended solids data al"'e those collected using depth-integrated samplel"'s.

The number of verticals collected across a stream depends on the accuracy being sought and on the the variation of sediment concentrations across the stream. Variability typically increases as the concentration of sediment increases. Another source of variability in turbidity and suspended solids analyses occurs in the analytical process. Subsampling a relatively small sample for analysis is difficult when the particulates concentration is moderate to high, and when the particle size is equivalent to sm~ll sand or lar~er. This situation arises when rel~tively l~rge samples <typically 250 ml to 1 liter> are collected in the field but the volume required for turbidity and total suspended solids analyses is small. Turbidity requires about 25 ml and suspended solids requires a few to 100 ml or more depending on ·the ~oncentration qf particulates. Consequently, the analyst must thoroughly mix the sample ~nd then obtain a representative subsample by decanting, pipetting, or other appropriate means. This process is exceedingly difficult and is a source of significant variability among samples containing high particulates concentrations and/or samples containing sand-sized particles. Sand settles too fast to enable an analyst to obtain a representative subsample. Assessment of the relationship between turbidity and total suspended solids must consider the sources of variability discussed above: C 1) Variabi 1 i ty in the turbidity analysis; <2> variability in the suspended solids analysist (3) sample variability; and (4) subsample variability. These sources produce variability in the relationship between turbidity and suspended solids. Many authors <Black and Hannah 1965; Duckrow and Everhart 1971; Peterson 1973; McGirr 1974; Carlson 1976; Pickering 1976; Stern and Stickle 1978; Langer 1980; McCart et al. 1980; LaPerriere 1983t Wilber 1983; Ge•::.rge and Lehni; 1984; Hach et al. 1984> recognize that turbidity is not necessarily a good quantitative indicator of the concentration of suspended REVIEW DRAFT S/09/85 PAGE qS solids becaase of the inconsistent correlation ~etween these parameters. Table 5-1 and Figure 5-1 present numerous correlations, both linear and logarithmic, between_turbidity and suspended solids concentrations reported by many authors. This information clearly demonstrates that there is no single equation relating these two parameters. Furthermore, most of the authors listed in Table 5-1 failed to consider percentage error. Kunkle and Comer (1971: reported a percentage error for their correlation ranging from -69 to +333 percent. Rllen (1979) studied a turbidimeter to determine its accuracy in pr~ed ict i ng suspended sediment concentrations. His res•.1ll;s showed maximum errors of -194 percent at one gaging station, +261 percent at another, and average prediction errors of 31 and 25 percent. Allen attributed the poor correlation to changes in the particle-size distribution of the sediment. Turbidity, an optical property, must be rscogni:ed as being entirely different from a weight concentration of suspended matter. This occurs because the si;e, shape, and refractive index of suspended particles which influence turbidity measure- ments are not directly related to the concentration and specific Qravity of the suspended matter. Particle size and particle si~e distribution are two key factors required in comparing suspended solids measurements to the actual turbidity present in a sample CBooth 1974>.

However, these parameters may be correlated under certain circumstances. Conseq~~ntly, using turbidity to predict suspended solids concentrations may be useful but the investigator needs to recognize all the potential variables, calculate the correlation including periodic updates, and calculate the percentage error associated with the correlation. In addition to treating the data collectively, regression analyses should include calculations of coefficients of determination and confidence limits for data in the low, medium, and high ranges. Since the relationship between turbidity and suspended solids concentration is dependent on local geological ~nd hydro- lc•g ical par.ameters Thelr~e are ~ characteristics,. any c.orrelat ion between th~_se needs to consider drainage, season, and discharge. natural and man-made sources of particulates that improve the correlation between these parameters, such as glacial streams and placer mining. Particle sizes and shapes and particle-size distributions from these sources probably exhibit less variability than in natural clear water systems. WATER COLUMN MEASUREMENTS Particulate levels in water have been measured by numerous direct and indirect techniques. Direct measurements of the number or weight of particles include total suspended solids, microscopic analysis, electronmicroprobe analysis, use of a Coulter counter, X-ray methods, and radioactive absorption. The most widely accepted technique, the total suspended solids test described vo:•l•.lr•1e Of above in Section ~. 1, involves filter~ir·,g a 1-t.l"•Own water through a glass-fiber filter followed by drying and weighing. Centrifugation has samples followed by drying and disadvantages to this technique. been used to concentrate One dis~dvantage occurs when REVIEW DR~FT ~/0~/63 PAGE IOI fine-grained_ sediment has organic material associated with it. Some organic material can have a density close to that of water, making it very difficult to separate (Gibbs 1974). Another dis~dvantage is that centrifuging is not good for'dilute water having less than about 10 mg/L suspended solids <Campbell and ~lliott 1975), Radioactive absorption has been used because the absorption of radiation is proportional to the mass present and therefore directly measures the concentration of suspended sedu1er1t <Gibbs 1974>. However, this method is impractical because of its expense. Microscopic analysis and the Coulter counter rely on counting the number of particles present, both of which \"lurnbe~· of assessment are time consuming. Additionally, conversion of the particles to weight per unit volume requires of particle size and specific gravity. Electronmicroprobe analysis and X-ray methods require expensive equJ.pment ar•d a relatively high level of expertJ.se.

This is the method specified in the Alaska water quality standards <ADEC 1965). Measurements related to light penetration may, under certain c1rcumstances, be an indicatiQn of the concentration of particulates. These measurements include turbidity <described above in Section 5.1> and transmissivity, Qr its inverse, light extinction. Microspectrophotometry, Secchi disk depths, and remote sensing using color infrared photography are also indirect measurement techniQues. These optical methods rely on absorption and/or scattering. Nephelometric turbidity measures the scattering of light by suspended particles, whereas the beam transmittance meter measures the attenuation of light by scatter1ng and absorption.

Measures of light penetration, such as compensation point, light extinction coefficient, wave length analysis, and transmissivity have been related to primary production. Furthermore, extrapolations have been made from these measures to other effects of particulates on aquatic biota. A chief gr~ol..md truth cor1siidered in concern in estimating suspended solids in water by remote sensing is obtaining adequate data <Shelley 1976). Two aspects that must be obtaining ground truth data are timing actual sample collection with the remote sensor pass, and standardi%ing sampling equipment and techniques. It appears that remote sensing is less precise than nephelometric turbidity rneas;urement s. Although no single optical measurement technique stands out as being the most accurate and precise, the nephelometric turbidity measurement as defined by APHA (1985) is the most acceptable indirect technique for measuring particulates for a number of reasons. First, the instrument specifications are well defined, leading to improved accuracy and precision. Second, turbidity is more widely accepted than many of the other indirect methods. Third, tur~idity measurements have been applied to many different water uses including water supply, recreation, and th• protection of aquatic biota. Fourth, turbidity levels may b• highly corr•lated with total suspended solids concentrations under certain circumstances. Therefore, nephelometric turbidity measurements are th• most applicable indirect measurement technique for particulates. Alaska water quality standards <AOEC 1985) The existing specify that turbidity measurements are to be performed in accordance with APHI=I ( l '385).

In some cases, a criterion may be a narrative statement instead of a numerical limit. The water quality standards for a particular water body consist of those criteria associated with the uses for which that water body is protected. Water bodies are classified by the uses for which th•y ar• protected. In Alaska, all water bodies except th• low•r Ch•na Riv•r and Nolan Creek <and mos~ Qf its tributaries> are clas.si1"ied 1"or prot•ction of all uses. Ideally, able to be measured relatively simply and be inexpensive, fast, precise, and accurate. It is desirable to use techniques that can be performed in the field without compromising the pr•cision or accuracy of th• m•asurem•nt. Additionally, standards should include only th• most applicabl• param•t•rs 1"or •ach wat•r use. For axampl•, turbidity crit•ria ar• suffici•nt to protect secondary recreational uses, so there is no need to have suspended or settl•able solids criteria. Standards must be sta·ced in clear, und•rst&ndabl• terms so that confusion do•s not arise ov•r th•ir int•rpr•tation. Id•ally, th•y should be appropriate 1"or all types of aquatic syst•ms and should consider seasonal, geographicAl, and flow differenc•s in natural particulate conc•ntrations. Criteria should be p•riodically reviewed and updated as new data or techniques for obtaining fast and accurate measurements become available. The particulates criteria should not be viewed as permanent fixtures but as essential parts of an REVIEW DRAFT 9/09/85 PAGE fOq evolving system to safeguard the current and future uses of Alaska's waters. 6.2 PROPOSED CRITERIA This section outlines suggested changes to the Alaska water quality criteria for particulates. The current wording, proposed wording, each criteria. and The supporting rationale are presented for rationale for retaining, changing, or deleting each criterion is based on the literature reviewed for this document. That literature has been used to formulate the discussions in Chapters 1 through ~. Therefore, the rationale sections are necessarily summaries of the preceding discussions. The reader is referred to the earlier chapters for more detailed overviews of literature relating to the effects of partic.ulates on water supply, recreation, and biota. Given the status of defensible sediment and knowledge, there are probably as many turbidity criteria for cvrt•in use categories as there are informed agencies or individuals interested in proposing them. In reality, there is probably rto one definitive level or concentration that is detrimental to each use in all systems under all circumstances. In sor11e instances, the existing criteria have been refined or modified to reflect the findings of a variety of researchers. With regard to aquaculture, definitive maximum suspended solids concentrations for egg incubation and rearing have been identified in the literature. In other instances an absolute maximum turbidity level or suspended solids concentration may not be appropriate. s~ch is the case for growth and propagation of freshwater and marine organisms. The proposed standards for these categories reflect seasonal fluctuations and site-specific differences in natural turbidity and sediment levets. They l1mit any ap~reciable incr•ase above natural levels in systems which normally carry 1 ow particulate loads while all .;:.w i r,g for some increase in systems which per1odically exhibit moderate to M1gh natural levels. REVIEW DRAFT '3/0'3/85 PAGE IIO _, - - - - - - The pro~osed particulates criteria presented below are made with two caveats from the Alaska Department of Environmental Conservation. First, the Department does not want to assess revisions to the existing water use categories as ·part of this study. Second, since it is the Department's responsibility to fully protect the various water uses, in setting criteria the Department prescribes limits be set on the most sensitive usa in each water use category. For aquatic biota, this means setting criteria for the most sensitive life stage of the most sensitive species in the most sensitive season. This approach is prescribed by the EPA. Table 6-1 lists water uses and the parameters that are essential to each. Parameters not appearing in a particular category are considered unnecessary for the protection of that 1.

Although light attenuation is not an issue related to the acceptability of drinking water, most people find water with 5 or more turbidity units obJectionable <Bruvold 1975). Sorensen et al. <1977) stat• that 0 to 10 turbidity units provide ar1 excellent source of water supply requiring only disinfection. They also state that 10 to 250 units provide good sources requiring only usual treatment, and that waters with turbidities greater than ~50 units are poor sources requiring special o~ auxiliary treatment. Therefore, the existing criteria has been modified to protect naturally clear so~rces of drinking wat~r. At the same time, the proposed standard allows for a greater increase where water contai~s higher natural turbidity levels which would require usual treatment or would otherwise be unacceptable as a water supply. With regard to sediment, the primary concern d i si rtfect ion. is that sediment not interfere with Interference with disinfection is directly related to the type and amount of organic sediment <volatile suspended solids> present in the water <Symons and Hoff 1975>.

There shall be no increase in settleable solids above natural conditions. A definitive maximum concentration of 3 mg/L. for incubating salmonid eggs and 25 mg/L for salmonid rearing is presented in the literature CSigma Resource Consul~ants 1979>. Thus, the maximum concentration should be limited in order to facilitate adequat~ water supply treatment and ensure successful incubation and rearing. The 3 mg/L level is important because most hatcheries support egg incubation and use of this level is the most conservative. Thera is no apparent reason for a turbidity criterion as such. The proposed suspended solids criteria would insure that turbidity-causing sediments are kept to a minimum. It should be noted that ultraviolet disinfection may be inhibited by turbidity-causing sediments. However, there are no data in the literature reviewed regarding specific turbidity levels that inhibit ultraviolet disinfection. A low level increase in suspended solids C3 mg/L) will limit the volume of turbidity-causing particles. The rationale for limiting settleable solids include the well documented adverse impacts of sediment accumulation on egg incubation and fry development <see Tables 4-l and 4-2>. 4.

Aesthetics and safety are the primary considerations for contact recreation such as diving, swimming, and w~ding. Data show that people prefer to recreate in clear rather than turbid water. A 5 NTU change in turbidity levels is noticed by most people. Cloudy water can also obscure dangerous rocks or other underwater obstructions. The upper limit for achieving these goals is 50 NTU <McSauhey 1966>. There is no basis for having d i f·ferent •:Jf the standards for lakes and streams. Therefore, this part standard is deleted.

Tha existing turbidity criteria afford a moderate to high level of protection for aquatic organisms as evidenced by data frorn Herbert at al. <1961>, Alabaster (1972>, Sykora et al. <1972>, Sorensen et al. (1977>, Langer <1980), Sigler <1981), BiS!iOn and Bilby ( 1982), NCASI ( 19S4b), Sigler at al. ( 1984), and Simmons <1984). Although, the current state of knowledge in Alaska is inadequate to describe the energy base of more than a few str•eams and lakes, it should be assumed that many systems depend on primary productivity to at least some extent. Quantitative information presented by Bell <1973>, Nuttall and Bili:Jy (1973l, McCart et al. (1980>, Van Nieuwenhuyse <1983>, and REVIEW DRAFT 9/09/85 PAGE oq LaPe~~ie~e et al. <1983) indicate that turbidity c~iteria are necessa~y fo~ the protection of aquatic systems ~hich depend on prima~y prod•.Lct i vity. Fu~therrnc•re, there is substantial evidence that tu~bidity has a negative impact on salmonid feeding <Alabaste~ 1972; Sykora et al. 1972; Langer 1960; Simmons 1964), salmonid growth <NCASI 19S4b; Sigler et al. 1984), salmonid distribution <Sigle~ 1981; Bisson and Bilby 1982; Si,ler et al. 1984) t and benthic rnacroinvertebrate popul~tions <Herbe~t et al. 1961; Sorensen 1977; ~aPer~iere et al. 1963). The suggested changes in the turbidity standa~d address the fact that increases in very clear water are likely to have a greater effect on a~uatic organisms and primary productivity than the same magnitude of increase in naturally turbid water. The reason for limiting fines in spawning g~avels is:to avoid smothering This eg~s and alevins by filling interstices in the is a volumetric, not a gravimetric concern.

However, beca,.tse the accepted technique is to weigh the f i rres, the pro:;~ posed criteria al"'e expl"'essed in terms of weight. Al thOI.Liijh, the percentage accumulation of fine sediment in a gravel bed is difficult to evaluate, the Department has found it to be a useful Cl"'iterion.

The criterion allowing a ma~imum of 30 percent fine sediment is not supported by the literature; this maximum should be lowered to 20 percent as a ma~imum <McNeil and Ahnell 1954; K•::.ski 1965; Shelton and Poll•ck 1966; BJornn 1969; Burns 1972; REVIEW DRAFT 9/09/85 PAGE flO - - - ~ - - - - BJ o~~nn et a 1.

The settleable 1'378; 8Jornl"l sol ids mea5H.Irement is re lat i vel y simple and reliable and can· be 1.1sed i 1"1 place of the percentage accumulation of fine sediment at the Department's discretion. EIFAC (1965) concluded that spawning gravels should be kept as free as possible from finely dividied solids. Van Nieuwenhuyse C1963) and Simmons <1964) suggest a settleable solids criterion of less than 0.1 ml/L for a high level of protection. Thus, the proposed criteria afford a high level of protection for salmonid spawning gravels. Suspended solids are also detrimental to aquatic organisms and, since suspended solids can not be correlated with turbidity on a state-wide basis, it is necessary to have a st~ndard for total suspended solids •. The propose~ criterion is rest~ictiy~ for naturally ·clear water but less restrictive for waters containing naturally high suspended solids concentrations. It is in agreement with the ~S mg/L criteria suggested by several authors CEIFAC 1965; Gammon 1970>; Alabaster 197~; Bell 1973; NAS 1973; Sorensen et al. 1977; Alabaster and Lloyd 1982; Wilber 1'383; and George and Lehnig 1984> to maintain optimal fisheries and prevent harmful effects on fish. This criterion offers a higr1 level of protection for sediment-free spawning and rearing waters while allowing some increase in streams and lakes which rece•ive natural sediment loads. It also accounts for the high degree of seasonal suspended sediment variability in Alaska's many streams and lakes. 1. Water supply: aquaculture a. Turbidity g~i~lins: Shall not e~ceed as NTU.

Hence, turbidity levels should be used as the primary criterion limiting the amount of particulates ~here light penetration is of paramount interest with compensation point as a secondary criterion. The suggested changes in the turbidity standard address the fact that increases in turbidity in clear waters are likely to have a greater affect on primary productivity and depth of the euphotic :one than the same magnitude of increase in turbid waters. The existing sediment criterion (no measurable increase in concentration above natural conditions> certainly affords a high level of protection.

The effects of' <6.35 mm diameter sediment on Juvenile salmonids and aquatic insects was assessed ln two Idaho streams. In a natural stream rif'fle, benthic insects ware 1.~ ·times more abundant in a plot cleaned of sediment, with mayflies And stoneflies '+ to 8 times more abundant, respectively. In small natural pools, additions of' sediment resulted in a proportional deer•••• in fish numbers. The amounts of sediment in the two streams studied did not have an obvious adverse effect on the abundance of fish or the insect drift on which they feed. In artificial stream channels, benthic insect density in fully sadimented riffles <>213 cobble embeddedness> was 1/2 that in unsedimented riffles. However insect drift was essentially the same in both. Fish in sedimented channels eMhibited hierarchical behavior, while those in unsedimented channels were territorial in behavior. Conclusions derived from experimental data are that sediments can affe~t aquati~ inse~t populations when deposited in riffles, reduce the summer rearing capacity of streams when deposited in pools, and reduce the winter fish capacity of streams when deposited in the larger interstitial spaces of stream substrate. If the percentage of fine sediment exceeds 20 to 30 percent in spawning riffles, survival and emergence of salmonid embryos begins to decline. When riffles are fully embedded with fine sediment, insect species composition and abundance changes. The abundance of Juvenile salmon in pools of small rearing streams declines in almost direct proportion to the amount of pool area or volume lost to fine sediment deposited in the pool. The number of salmonid fish a stream can support in winter is much reduced when the interstices in the stream substrate are filled with fine sediment. The percentage of fine sediment in riffles not only provides a measure of the suitability of the riffles for embryo survival, but is also an index of the amount of fine sediment being deposited in pools or substrate interstices. ·~ /c, I • REVIEW DRAFT 8/19/83 PAGE A-8 - - - - REFERENCE• ~larkson, C.C., D.

Fecundity levels were also greatly influenced by increased levels of suspended silt. The filtering rates for turbidities used in the life table experiment were 2.S ml/animal/hr at 2 NTU, but declined to 0.4 ml/animal/hr at 33 NTU. When assimilation efficiencies are factored in, animals feeding at 2 NTU would obtain 16 times more energy than animals feeding at 33 NTU. The mean body length for control animals was significantly smaller than the mean body length of Q QY!•!i raised in both low and high silt environments. The most likely reason for this discrepancy is that animals growing in the suspended silt environment channel more energy into increasing body size than into reproduction. Although the animals raised in suspended silt were larger, they were not as healthy as tho•• rai••d in the ab•ence of silt. Specifically, the individuals raised in silty water lacked carapace strength and re•iliency. It was concluded that both filtering efficiency and assimilation rates are severly depressed at even low concentrations of suspended silt and clay. Furthermore, the population growth rate of zooplankton was significantly diminished by suspended silts and clays. gjq REVIEW DRAFT 8/19/85 PAGE A-24 - - - - - - - i - REFI::RENCE 1 !V!c:C:art, P. 3. , P.

The relationship between particulates in the water and the presence of disease causing organisms was documented from literature. Turbidity .ven at low levels, above 1 turbidity unit, interferes with disinfection and prevents maintenance of an effective disinfectant agent <e.g., chlorine) throughout the distribution system. Indications are that bacteria and viruaea can be protected by certain kinds of particles from inactivation by chlorine. Inorganic ~rticles can cause turbidity and probably have no bearing on the potential protection of pathogens. Small organic particles, on the other hand, may protect pathogens. Therefore, in evaluating turbidity, the nature of the particles in the water must be taken into account. 9/q REVIEW DRAFT 6119/8~ PAGE A-40 - - fll'ii!l.· - - - - - REFIERENCE1 Tappal, P. D., and T.

PAGES: ~S-66 KEY WORDS: Turbidity, Settleable Solids, PAR, Gross Productivity, Algal Productivity, Recreational Activities, Criteria A strong positive correlation was observed between incident PAR and gross productivity, attesting to the importance of light in regulating primary production. This relationship provides the partial basis for a model which could be used to predict algal productivity at different turbidity levels, Recreational activities such as canoeing and fishing would probably be popular on Birch Creek if the channel were rehabilitated t6 allow fish· passage, and if turbidity could be maintained below 200 to 300 NTU. The results of this study support the contention that a settleable solids standard of <0.1 ml/L for receiving waters could be reasonable. With regard to turbidity, the following tentative criteria are suggested: 6 to 2~ NTU high level of protection, 25 to 100 NTU moderate, 100 to 300 NTU low, 300 to ~00 NTU very low. qf:4 REVIEW DRAFT -&1-19/S~ PAGE A-4~ REFEREBCE1 Vanous, R. 0., P.

Sur-vival to emergence, time of emergence, and alevin condition at emergence were significantly influenced by gravel size. Mean percent survival to emergence increased from 1 percent in 2-mm gravel to 76 percent in 26.-~-mm gravel. Survival of ova to swim-up stage in a gravel free incubator was aa percent. Differences in -!)ercent survival were inost significant within the 2 to a mm gravel range. Poor survival of trout alevins in tne 2 to 4 mm gravel was the result of entrapment. Tne time to emergence also increased with gravel size. ~arger alevins, which emer-ged later from coar-ser gr-avels had the least yolk reserve. Premature emergence of free embryos and shortening of the alevin emergence period in 2.0-mm gravel was identified as a stress response. q /·-1'-1 REVIEW DRAFT ~9/85 PAGE A-48 - -I r !

Egg experiments indicate that concentrations of up to 1000 mg/L did. not significantly affect the hatching success of yell~w perch, blueback herring, alewife or American .shad eggs. The •~m• concentrations did however significantly reduce the hatching success of white perch and striped bass, whereas lower c:oncentr-ation• did not. EMper-iments with larvae indicated that concentrations above ~00 mg/L significantly r-educ:ed the survival of striped bass and yellow per-ch. Concentrat ior'ls above 100 mg/1 significantly r-educed the survival of American shad lar-vae continously eMposed for-96 hours. The significance of these r-esults are discussed ir'l r-elation to changes in sediment loading in estuaries. q/q REVIEW DRAFT ~/8~ PAGE C-2 - -,1 - - - - -'' -r-:i i REFI5:RENCE REFI5:RENCE LOCI~TIONa IMPIJRTANT PAGIES1 B~•hm•~, M.

Generally, filter feeders and warly-life stages were mora sensitive than bottom dwellers and adults. Exposure to sublethal concentrations significantly increased tne hematocrit value, hemoglobin concentration, and erythrocyte numbers in tne blood of a variety of fish.

There is common agreement that optical instruments provide an inferred rather than a direct measurement of suspended solids and that it is almost iMpossiblit to relate sediment concentrations and optical characteristics from one turbidimeter, standard suspension, or unit of measure to another. Relatively few studies relate animal responses to the actual weight per volume concentration of particles in suspension. Ratner, they correlate response with - turbidity. It is unlikely that the light absorbing and scattering ~roperties of suspended particles directly affect animals. Because. turbidity involves optical properties that cannot be correlated with the weight/volume concentration of suspended material, which directly affects aquatic biota, several investigators suggest that turbidity only be used as a nontechnical descriptor. Gravimetric techniques probably """' represent a more accurate measure of the effects of suspended solids on aquatic biota while optical measurements may be preferable for photosynthetic or aesthetic purposes. Laboratory eKperiments often do not duplicate natural conditions or reflect natural levels of organism tolerance to turbidity and suspended material. The review also discusses the effects of suspended material and turbidity on corals, bivalves Cclams, oysters, mussels) copepods, and fishes. The discussion includes information about eff•cts on eggs, JUVenil•s, and adult organisms. yfct REVIEW DRAFT --8/19/8~ PAGE C-16 ,.,..., APPENDIX D GENERAL LITERATURE--MARINE The re~erances listed herein were reviewed by proJect team M8mbers and JUdged to bet (1) Too gerteral, (2) Inapplicable to the scope of this proJect (e.g., related topics such as biolLogical life history) 1 (3) The information contairted irt a sp~:ific re~erence was eKplained in more detail in one or more of the references appearirtg above in AppendiK c, or, Cit) Only a smalll of the reference Nas applicable and t~is information is cit1~ in the teKt of the report.
