Work accomplished during the first year is broadly divided into: (1)Procedures Manual,(2)Water Quality Data Collection,(3) literature Review. 2 -SUMMARY OF 1980 WATER QUALITY PROGRAM 2.1 Water Quality:Data Collection Procedures Manual The water quality data collection procedures manual was completed and submitted to Acres American,Inco in July 1980 and is presented in Appendix A.The only significant deviation to ~he water quality monitoring program as described in the manual is relative to organic carbon. Total organic carbon and total inorganic carbon were not routinely analyzed.Consequently,there are few data points for these parameters. susi2/b - 1 - ..... ..... i - ..... 2.2 2.3 1980 Water Quality Data Collection Water quality data were collected during summer at the Vee Canyon site four times (Table 1)and once at Gold Creek (Table 6).Detailed suspended solids analyses were performed on two sets of samples collected using a depth integrated sampler at the Vee Canyon site during summer (Tables 2 and 3).Winter sampling was conducted during October 1980 and January 1981 at both sites.The water quality data are presented in Table 1 (Vee Canyon)and Table 6 (Gold Creek),and the detailed suspended sediment data are presented in Tables 4 and 5 (Vee Canyon)and Tables 7 and 8 (Gold Creek).It should be noted that suspended solids concentrations presented in the tables of water quality data are not comparable to the suspended solids concentrations presented in the tables of detailed suspended sediment analyses because of differing collection techniques.The detailed suspended sediment analyses are representative of the entire water column since the samples were collected using a depth integrated sampler. Watana Continuous Water Quality Monitor A continuous water quality monitor,recording the date and time as well as temperature,pH,oxidation reduction potential,dissolved oxygen,conductivity,and temperature -corrected conductivity I was established near the Watana site in October 1980.A computer program to process the data tapes is currently under development by the supplier of the instrument,and it will provide summaries of the data on a daily and a monthly basis.The probe assembly is scheduled to be removed from the river just prior to breakup and re-installed as soon after breakup as practicable. susi2/b - 2 - .- The ,-and been and are r 2.4 Summary of Existing Data A review of existing water quality data resulted in a compilation of historical U.S.Geological Survey (USGS)data from four sites on the Susitna River.Tables 9 through 12 present the maximum,minimum,and mean values and number of observations for parameters measured by the USGS at the following stations:Near Denali I Vee Canyon I Gold Creek,and Sunshine.Five Alaska Department of Fish and Game (ADF&G)reports,published between 1974 and 1978,were reviewed for water quality data.These reports were primarily concerned with fish distribution and secondarily with water quality.The water quality data contained in these reports has not been summarized because most of it deals with sloughs and tributaries of the Susitna . R&M Field Data Index,first published in July 1 1980, revised in January,1981,identifies data that have collected by the USGS and others on the Susitna River its tributaries.Names of sites and periods of record given for locations where water quality,water temperature,and suspended sediment data are available. Appendix C of the index highlights the ADF&G reports prepared from 1974-1977. --,3 -RECOMMENDATIONS FOR 1981 WATER QUALITY DATA COLLECTION The same sample locations utilized during the 1980 water quality monitoring program will be used during 1981.Samples will be collected at Vee Canyon and Gold Creek during the following periods: susi2/b - 3 - 1.Spring breakup 2.Summer Jow-flow 3.Summer after a heavy rainstorm 4.Immediately prior to freeze-up 5.Winter low-flow An objective of the 1981 program will be to sample the spring snowmelt and summer rainstorm flood events,during the rising and falling limbs of the hydrograph.These should produce three to five sampling points during each event which will provide an opportunity to determine the variance in short-term water quality. All field parameters will continue to be measured.Although settleable solids have been·0.1 mill or less,another summerJs worth of data should be collected to insure that this parameter is determined during a variety of hydrologic events. All of the nitrogen and phosphate forms,chloride,color, hardness,sulfate,TDS,TSS,and turbidity will be measured.It is also recommended that COD values be determined because of two high values measured during last year's program. Since all four measurements of uranium were below the detection limit,this parameter will be eliminated.Gross Alpha radioactivity will also be eliminated because the values at both sample stations were less than 15 pC ill ,the drinking water standard. Total organic carbon and total inorganic carbon will be.determined during all sample periods because these parameters were only measured once at each sample station last year.These parameters were added subsequent to initiation of the water quality program last year at the request of Acres American,Inc. susi2/b - 4 - -- !"'" I The sampling frequency for organic chemicals will be reduced for this year1s program.During 1980,the concentrations of pesticides were essentially at or below their respective detection limits for the procedures used by Chemical &.Geological Laboratories of Alaska,J nco The detection limits for these parameters match the drinking .water standards,but are really not low enough to meet the criteria for freshwater aquatic life.Therefore,it is recommended that a PCB and pesticide scan be run on samples collected at the two sites during the summer high-water and summer low-water periods.This scan will quantify pcals, chlorinated hydrocarbons,and phenoxy acids,the organic chemicals of interest in the study area that appear on EPA's list of priority pollutants. The ICAP Scan will be continued because many of the elements measured by this method exceed their detection limits.These include aluminum,barium,calcium,iron,potassium,magnesium, manganese,sodium,silicon,strontium,titanium,and tungsten.It is also important to note that Chemical &Geological Laboratories of Alaska,Inc.analyzes all 33 elements in the scan for $50.00,less than the cost t9 analyze six of the above using different procedures.Since the detection limits for many of the remaining parameters are not low enough to determine their impact on freshwater aquatic life,it is recommended that the following parameters be analyzed at both sample stations during the summer low-water period and during the winter low-water period using techniques that provide appropriate detection limits:Arsenic, boron,cadmium,chromium,copper,lead,mercury,nickel, selenium,silver,strontium,vanadium,and zinc.Additionally, beryllium and cyanide should be determined at the same time as arsenic,etc.,using techniques that provide detection limits that will enable a determination of their potential effects on freshwater aquatic life. susi2/b - 5 - susi.4/e ..... .- TABLE I WATER QUAL1TY DATA -SUSITNA RIVER NEAR CANTWELL (VEE CANYON SITE) DATE SAMPLED Field Parameters (1) " Date Date Date Date Date Date 6/19/80 8/8/80 9/5/80 9/17/80 10/17/80 1/13/81 Dissolved Oxygen 12.4 8.7 9.7 13.8 10.7 P~r'cent Saturation 98 82 84 104 84 '"""pH,pH Units 7.8 7.9 7.8 7.6 7.6 7.2 Conductivity,umhos/cm @ 25°C 150 144 171 124 142 242 .-Temperature,°C 5.7 9.3 5.3 5.9 -0.1 0.1 Free Carbon Dioxide (2)2.0 l.7 3.6 4.5 5.5 22.0 Alkalinity,as CaC0 3 47 54 81 63 88 187 r- Settleable Solids,mill 0.1 <0.1 <O.l <0.1 <0.1 «0.1 ~Laboratory Parameters (1)(3) ~Ammonia Nitrogen 0.26 0.10 <0.05 0.26 <0.05 Organic:Nitrogen <0.1 0.22 0:62 0.28 0.85 KjE~ldahl Nitrogen 0.26 0.32 0.62 0.54 Nitrate Nitrogen 0.19 0.15 0.15 0.09 <0.10 <0.1 Nit.rite Nitrogen <0.01 <0.01 <0.01 <0.01 <0.01 """.,Total Nitrogen 0.45 0.47 0.71 0.54 0.85 Ortho-Phosphate <0.01 0.03 0.05 <0.05 <0.01 <0.01 ~Total Phosphate 0.05 0.03 0.09 0.10 <0.01 0.07 AI kalinity 106 '66 ~Chemical Oxygen Demand 28 12.6 124 156 12 6 Chloride 3 9 11 8 18 18 Conduc.tivity 190 ~ True Color,Color Units 40 10 10 10 Hardness,as CaC0 3 (4)51 61 69 55- - 3 -_________~---------------_t ~ .Laboratorv Parameters (1 )(3)(continued) Sulfate 4 9 9 7 13 16 ,<:;!~Total Dissolved -90 114 38 149Solids70115 Total Suspended Solids 242 310 25 132 8.3 0.6 TUI-bidity,NTU 95 95 10 33 1.8 0.35 Uranium '.<0.05 <0.05,-Radioactivity,Gl-OSS Alpha,pCi/1 11.6:!:0.6 ,Total Organic Carbon 23 Total Inorganic Carbon 106 Organic Chemicals Endrin <0.0001 0.000.

For Acres American,r ncorporated 1) PROCEDURES FOR WATER QUALITY DATA COLLECTION '. PURPOSE The aim of the data collection program is to provide basic water quality information for fisheries studies,reservoi r studies and for the establishment of baseline parameters on the Susitna River.From the data,regional and local variations in water quality will be defined,as well as seasonal variations as they relate to streamflow and climate. This information can then be used to determine the effects that dam construction,impoundment and regulated flow might have on water quality upstream and downstream of the proposed damsites. .- 2)SAMPLING:LOCATIONS AND FREQUENCY Tables 1 and 2 outline the proposed water quality data collection pro- gram.The first table shows locations of data collection sites I para- meters to be measured,frequency of observation and agencies collecting the data.Table 2 lists field and laboratory·parameters to be collected by R&M and the U.S.Geological Survey.

I 1 I I o o o o Both R&M and the USGS will be collecting data at the Gold Creek station so there should be a very good record at this site.This will allow more accurate extrapolation of data collected at other sites.R&M will conduct event-oriented sampling at Gold Creek.The site will be occupied during flood events and water quality sampled three to five times through the hydrograph. R&M will install a continuous water quality recorder for key parameters at the proposed Watana damsite.These parameters will include: a)pH b)Dissolved Oxygen c)Temperature d)Specific Conductance Laboratory testing for uranium,organic chemicals and radioactivity, gross alpha will be done three times at two sites on the Susitna River during the 1980 season. As pal~t of the National ~tream Quality Accounting Network (NASQAN) The U.S.G.S.is conducting an expanded data collection program at Sustina Station.A more detailed description of the program can be found in Geological Survey Circular 823-A. -- 3)FI ELD PROCEDURES This section describes sample collection and handling,procedures for measuring field parameters (dissolved oxygen,pH,·temperature,carbon dioxide,conductivity,al kalinity,and settleable solids),analytical methods,detection limits,and procedures for preservation and shipment of sample~for laboratory analyses. A.Sample Collection and Handling Three grab samples are.collected at each water quality station - one at the left over-bank,one at the right over-bank,and the third at mid-channel.Grab samples are collected with a 2.2-liter Van'Dorn sampler at least one foot below the surface.Dissolved oXYf!en,.settleable solids and temperature are determined on each gr'ab sample and the values averaged to provide one IIcompositell value.Conductivity I pH and alkalinity I are determined on a composite sample made from equal parts of each grab sample. Samples for laboratory analyses are collected from the composite sample (see below for preservation and shipment). B.Field Parameter Procedures Standardize YS I Model 5"B Dissolved Oxygen Meter as follows: 1.Shake SOO-ml bottle containing about 300 ml distilled water to saturate the water with oxygen,wait 15 minutes to allow, oxygen bubbles to rise to the surface and disappear I 2.measure temperature of water and record, 3.record barometric pressure, 4.select standard dissolved oxygen value from chart of oxygen saturation versus temperature and barometric pressure to calibrate meter,. 5.set II zero ll and Ilfull sea/ell using appropriate knobs,and 6.calibrate meter to value dertermined in step 4. Temoerature and dissolved oxyaen are determined on each graD sample.Immediately after securing each grab sample,attach 5 .- tubing to Van Dorn sampler and fill 300-ml beaker from the .bottom,allowing at least three times the volume of the beaker to overflow into a 3-liter container.Insert oxygen probe into 300-ml beaker and determine dissolved oxygen in mg/l.Samples should be stirred continuously by raising and lowering the probe at a rate of about one foot per second during measurement.While one field-,team member measures dissolved oxygen,the·other empties.. the remaining sample from the Van Dorn sampler into the 3-liter container and measures temperature. Settleable solids is determined by filling an Imhoff cone to the 1000-ml level with each grab sample.Allow to remain undisturbed for'45 minutes,then run a rod around the inside of the cone (once),and wait 15 minutes.Read the settleable solids from the graduations on each Imhoff cone and report in mIll.These values can be averaged to provide one IIcompositeJl value. Conductivity,pH and alkalinity I are determined on a composite sample. Conductivity (or specific conductance)is measured using a YSI Model 33 S-C-T meter.The probe is placed in the sample to be tested,the instrument "red lined l1 ,and ,the conductivity read off the appropriate scale.Make temperature correction and report. results in umhos/cm at 25°C. E.!::!is determined with a VWR Scientific Model 55 pH meter.The meter is calibrated by placing the probe in 7.00 pH buffer,ad- justing the temperature knob to the temperature of the buffer,and adjusting the pH to 7.00 with the calibrate knob.The probe is rinsed with distilled water and placed in pH 4.0cr buffer.Adjust the meter to 4.00 by using the span control (temperature)knob. pH of the sample can be measured after rinsing the probe with distilled water. 6 Alkalinity is measured using a potentiometric titration to an end point pH determined by the alkalinity concentration as follows: Alkalinity,mg/l 1st End Point (C)2nd End Point (D) 30 5.1 4.8 150 4.8 4.5 '.500 4.5 4.2 Calibrate the pH meter.Measure 100-ml sample and pour into beaker.Titrate with 0.020 normal sulfuriC acid to appropriate end points.Calculate al kalinity as follows: A =(2C -D)X 0.020 X 50,000 100 where,C =ml titrant to 1st end point, D =ml titrant to 2nd end point. Report al kalinity in mg/l as CaC03 . Note:If initial pH exceeds 8.3,record the ml titrant used to reduce the ph to 8.3 aild proceed as above.The table below is taken from page 281 of Standard Methods,14th edition,and shows al kalinity relationships for determining the concentrations of bicar'- bonate,carbonate}and hydroxide alkalinity.
