- - 1 -INTRODUCTION 1 .1 -Objectives This report describes the water quality program conducted by R&M Consultants during Phase 1 of the Susitna Hydroelectric Project, and presents all the water quality data collected to date under Subtask 3.03. The aim of the data collection program is to provide basic water quality information for fisheries studies,reservoir 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 dam construction and impoundment with regulated flow might have on water quality upstream and downstream of the proposed damsites. 1 .2 -Report Contents Following a general description of the water data collection program,the data are presented with respect to the year in which they were collected.Any variances from the procedures in the R&M Consultants Procedures Manual,July 1980,are described relative to each data set.Water quality data collecte.d during 1980 are presented in Section 3.0,and 1981 data in Section 4.0. Suspended sediment analyses results are also divided into the year in which the samples were collected along with a description of sampling techniques.A summary of water quality parameters collected by the u.S.Geological Survey is included in Section 5.0 with R&M data summarized in the same format for comparison. Section 6.0 presents the data collected by the continuous water quality recorder in a summarized format with a description of its operation to date.Attachment A contains water temperature data available from the U.S.G.S.dating back to 1974 at Gold Creek. Also included are existing data from Vee Canyon,Susitna Station and temperature data collected by R&IVI during 1980 and 1981.A revised version of the R&M Consultants Procedures Manual for Water Quality Data Collection is presented in Attachment B. s9/L 1 - 1 2 -SAMPLING LOCATIONS AND FREQUENCY R&M Consultants has collected samples for water quality analysis on the Susitna River at Vee Canyon (U.S.G.S.linear Cantwell ll site),Figure 2.1,and at Gold.Creek,Figure 2.2,on an event oriented basis.During the 1980 field season five analyses were conducted at Vee Canyon and two at Gold Creek.For 1981 the program was expanded'to include two complete hydrograph samples for a total of nine analyses at Vee Canyon and nine at Gold Creek. The dates and descriptions of specific events along with sampling results are further outlined in Sections 4 and 5. Generally the sampling was scheduled according to the following events. 1.Breakup 2.Early summer (maximum effect of glacier runoff and snowmelt) 3.Heavy rainstorm 4.Pre-freezeup - ~, 5.Winter (under ice cover) For the purposes of this schedule the seasons are defined: Breakup -from the time ice begins to breakup until recession of spring runoff. Summer from the end of breakup until the water temperature drops to essentially OOC in the fall. Winter -from the end of summer until breakup begins. The sampling schedule should satisfactorily supplement the U.S.G.S.program,which is oriented towards a fixed sampling time interval. Table 2.1 presents a listing of the parameters monitored by R&M Consultants with respective methods used for analysis and their detection limits.In some instances the detection limits vary below or above the values in Table 2.1.This is attributed to inconsistencies in values received from the laboratory.All values are presented as received from the lab with few exceptions.The exceptions include typographic errors made at the laboratory which were verified as mistakes. susi8/j 2 - 1 TABLE 2.1 WATER QUALITY PARAMETERS ANALYSED FROM VEE CANYON AND GOLD CREEK BY R&M CONSULTANTS,INC.(1) Data Available Detection from the ~ Method(2)Limit(3)(4)U.S.G.S.

Data were collected similarly at Gold Creek at the following dates and events. 8/8/80 10/14/80 After a heavy summer rain. Pre-freezeup. - Results are listed in Table 3.2. Procedures for water sample collection and field measurements are detailed in Attachment B.These are,however,the revised procedures and the following variances in methods were applied to the 1980 season. Field measurements of dissolved oxygen,pH,conductivity, temperature,alkalinity and settleable solids were taken from samples collected with a Van Darn,2.2 liter,sampling bottle. Samples were obtained one foot below the surface and at three locations across the channel.These locations are marked on a cableway at both Vee Canyon and Gold Creek to insure that the samples are taken at consistent points throughout the season.The width of the channel at high water is roughly divided into quarters,and sampling is conducted at the left quarter,at midchanneJ and at the right quarter.When a sufficient quantity of water is collected at each site,each sample is analysed for dissolved oxygen,temperature and settleable solids.The three samples are then combined and mixed well before measuring the pH,conductivity and al kalinity.This composite is then stirred again before separating into five 1-quart.bottles for quantitative analysis.The 5 unfiltered samples (3 preserved)were then sent directly to the lab on ice. susi4/u 3 - 1 Additional samples for the analysis of·organic chemicals (pesticides,herbicides),gross alpha radiation,and uranium were collected on August 8,1980 at Vee Canyon and Gold Creek. However,only a low concentration of gross alpha was detected. Problems with instrument calibration prevented the measurement of dissolved oxygen on August 8 and September 5 at Vee Canyon. The low D.O.reading on August 8 at Gold Creek is possibly further evidence of calibration problems.Another significant deviation to the program is the lack of data points for total organic carbon and total inorganic carbon.These parameters were not routinely analysed in 1980. 3.2 -Suspended Sediment Analysis During the 1980 field data collection season,R&M acquired a depth integrated sampler for the purpose of obtaining more representative sediment samples to facilitate a detailed analysis of suspended sediment.Previous studies were limited to measurement of total suspended sediment from the composited grab samples obtained at a depth of one foot.The use of a depth integrated sampler provides a representative sample from the entire column. Total suspended sediment from the grab samples is still measured. These values,however,are not directly comparable to the depth integrated values since variations in sediment concentrations can be expected throughout the water column. At least ten depth integrated samples are collected across the channel at each site.Three of these samples were selected for particle size analysis.The particle size count is done by Chemical and Geological Laboratories of Alaska,Inc.The procedure is basically to count,under a microscope,the suspended sediment particles of a certain size range,then calculate the percentage of that size range within a grid. The results from the 1980 suspended sediment analyses are presented in Tables 3.3 to 3.5,for Vee Canyon,and Table 3.6 for Gold Creek. - - - - - - susi4/u 3 - 2 TABLE 3.1 R&M CONSU LTANTS,INC. 1980 WATER QUALITY DATA -SUSITNA RIVER AT VEE CANYON .- NOTE:Dash indicates data not available.

Samples were obtained at the same locations at Vee Canyon and Gold Creek as in 1980.The collection procedures were modified so that the depth integrated sampler was substituted for the Van Dorn grab sampter.Late in May of 1981,following breakup,a comparative analysis was conducted at Gold Creek between the grab sampling technique and a sample obtained through the water column using the depth integrated sampler.The results from the grab sample appear in Table 4.3 under May 27,1981 (A),and the data from the depth integrated analysis are listed under May 27, 1981 (B).These data and U.S.G.S.data also collected on May 27,1982,are compared in Section 4.4.Although no significant differences in most data points were immediately evident it was nevertheless felt that the depth integrated method could provide a more representative sample.Therefore this technique was incorporated into the field procedures for all subsequent sampling.During freezeup and winter sampling the depth integrated sampler could not be used due to frazil ice blocking the inlet port.Logistics involved in cutting a hole through the ice to accommodate the sampler were also not feasible.Consequently during these events the grab sample method was employed. The standardization procedure for the YSI Model 51 B dissolved oxygen meter has been modified somewhat.An air calibration method has been added to verify the calibration setting from the saturated oxygen method.Using the latter method only introduces the possibility of inaccurate calibration due to misreading of the barometer or taking a reading from a barometer out of calibration. See the revised procedures manual in Attachment B for further detai Is. Three of the five samples for quantitative analysis are now filtered in the field through a glass fiber filter and a 0.45 micrometer (um) membrane filter. Procedures for measurement of the field parameters have under- gone further modification,after recommendations were made by Dana Schmidt (TES).Dissolved oxygen and temperature measure- ments are taken directly in the river at the sampling locations. Conductivity and pH are measured in each sample,instead of the composite,and a mean value is reported.Al kaJinity is determined from a well mixed composite of the three samples. s9/j 4 - 1 Due to time restraints,from sampling both Vee Canyon and Gold Creek on the same day,titration of the alkalinity sample is performed at Watana Camp.However,the sample is kept on ice until titration begins.The pH sensor failures prevented the measurement of al kalinity during several sampling periods at both sites.When this problem occurred in August 1981,the alkalinity was determined in the laboratory and it should be noted that there was a significant delay between obtaining the sample and al kalinity measurement. Uranium measurements have always fallen below the detection limit and random samples of gross alpha radiation show levels below 15 pCi/l,the minimum standard for drinking water. Organic chemicals were measured twice this season,once during a hydrograph peak in July and again at a low discharge in September,at both sites.Concentrations of PCBls,chlorinated hydrocarbons and phenoxy acids (pesticides and herbicides)fall below the minimum detection limits for all samples collected. Total organic carbon and total inorganic carbon have been determined for all sampling events.This parameter is measured out of state which means a lag period in reported data. Sampling was conducted on the folloWing dates and corresponding events. - - - - - Vee Canyon 1/13/81 5/20/81 6/18/81 6/30/81 8/2/81 8/3/81 8/3/81 9/15/81 10/7/81 s9/j Gold Creek 1/14/81 5/27/81 6/17/81 6/30/81 7/1/81 8/2/81 8/3/81 9/14/81 10/8/81 Event Winter,under ice cover.

It should be noted that the U.S.Geological Survey reports particle distribution as a percentage by weight and R&M Consultants is reporting percent by size.Therefore,these values are not directly comparable. 4.3 -Bedload Sampling During the summer of 1981,R&M Consultants,in cooperation with the U.S.Geological Survey,collected bed load samples on the Susitna River at Sunshine and Gold Creek,on the Talkeetna River near Tal keetna,and on the Chulitna River at the Chulitna gauging station (near Tal keetna).The purpose of the investigation was to define a value for bedload transport as related to discharge.Each site was sampled three times,covering a broad range of river discharges.The U.S.G.S.is responsible for sample analysis and data reduction.Provisional data is presented in Table 4.21. 4.4 -Comparison of Sampling Technigues A comparison was made by L.A.Peterson &Associates of the laboratory analyses of water samples collected by R&M at Gold Creek on May 27,1981,using grab and depth-integrated sampling techniques.The following conclusions were made concerning the comparison of grab and depth-integrated sampling at Gold Creek . 1.Generally,there was no major difference in the water quality characteristics of the two samples.The magnitude of variation for those parameters that displayed a difference was much less than an order-of-magnitude. s9/j 4 - 3 2.The different levels displayed by some parameters were too minor to be able to draw a definite conclusion as to the reason(s)for their respective differences.However,it is likely that TSS and turbidity varied as the result of the two sampling techniques.Chloride data showed minor differences, but still indicated very low values. - -3.Any of the following possibilities could account for the different values noted in some paramters: A.Sampling techniques caused the difference, B.Sample times were different by 21a hours and the water quality may have actually changed slightly during this period,and, C.Laboratory error. A comparison was also made between depth-integrated samples collected by R&M and by U.S.G.S.Significant differences in values were apparent for TOC and nitrogen.Toe data collected by R&M are believed to be in error for this sample.Discussion with U.S.G.S.personnel indicated that the variances in nitrogen values may have been due to differences in the analytical procedures used in the laboratories.Both values were within the range of observed values for summer. - - - - ~I s9/j 4 - 4 .... ,~......

The R&M Field Data Index,revised in July 1981,identifies data that have been collected by the U.S.G.S.and other agencies on the Susitna River and its tributaries.Names of sites and periods of record are given for locations where water quality,water temperature,and suspended sediment data are available. susi11/x 5 - 1 susi6/s7 TABLE 5.1 WATER QUALITY DATA SUMMARY SUSITNA RIVER - - - Agency: Station: Elevation: u.s.Geological Survey HR.DENALI -1957-1981 2440 FT.

The purpose of the continuous recorder is to provide a record of water quality parameters through the winter months when a thick ice cover makes conventional sampling techniques arduous,and during the summer to supplement the water quality data collected at Vee Canyon and Gold Creek. The percentage of usable data on the summaries received to date has been less than expected.Problems with siltation around the sensors,calibration and equipment damage have prevented a continuous record.Inaccessibility of the sensors in the winter prevents an accurate calibration procedure and maintenance of the sensors is not feasible. Several problems with the sensors have developed over the span of this program.A design limitation of the pH sensor prevents its use during the winter due to freezing of the gel,and this sensor must be disconnected before freezeup.The stirrer on the dissolved oxygen sensor is likely to be mired in accumulated debris if not periodically cleaned.This problem is evident in the November 1980 summary where the dissolved oxygen values steadily decrease as the month progresses.The electric stirrer motor attracts magnetic particles in the sediment and this eventually jams the stirring paddle so that water is no longer circulated sufficiently about the sensor membrane.Therefore,the pH and D.O.values from November (freezeup)until April could be unreliable. On April 16,1981,the sensor assembly was extracted from the ice to prevent damage to the unit during breakup.The unit remained inoperable through lVlay while a damaged cable was repaired and the sensors cleaned and calibrated.The monitor was put back in service on May 21,1981,and recorded data through June.At this time it was evident that the damage to the cable was more extensive than previously realized and the entire unit was shipped to Martek for repair.The resultant data summaries for May and June contain data believed to be invalid'for dissolved oxygen and conductivity.Temperature,pH and oxidation reduction potential susi8/i 6 - 1 appear to be reasonable values I however,due to the problems experienced with the other parameters,these values could be unreliable as well. Some temperature values on the May summary have been modified to exclude erroneous readings found on the raw data printout.All the dissolved oxygen values have been lined through and are to be dismissed as inaccurate. Through the month of July the monitor was out of service while the manufacturers repaired the sensor cables. The recorder and sensor assembly were reinstalled at the same location on August 5,1981 and has remained in service since then. All values on the August summary appear to be valid and compare well with periodic measurements made with the YSI portable instruments.The dissolved oxygen values listed on the summary become less accurate towards the end of the month as magnetic sediment particles accumulate around the electric motor shaft. This problem remains unsolved. The adjustments noted on the summary during August 12 and 13 are due to a period when the instrument was being calibrated,and 14 of the 24 daily readings had to be omitted from the mean values.The last 14 readings on August 12,and the first 14 readings on August 13 had to be disregarded while the instrument stabilized.The values noted on the summary are,therefore, means from only 10 values per day.Tables 6.1 to 6.13 present the summarized data recorded by the monitor. -. ..... susi8/i 6 - 2 I J j j 1 J )~J 1 1 I J 1 I i I,~ J~ l\1 U t ~ ::\ OCTOBER,1 '?flO MIN.1iAX.MEAN MEAN [I;)'{TEMI"TfliP TEliP l~f'l (C)(C)(C) n "00.21 '-00.04 -00.16 08.09 24 '''00 •~!2 00.05 '-00.10 OB.15 ~~~:;00.06 00.18 00.13 08.4', ~~6 00.1.6 00.26 00.20 00.~)O ;:~'7 O().:19 00.2'7 00.22 00.60 20 00 •:ll3 00.24 00.20 08.::;'7 29 O()•18 00.21 00.19 08.56 31 00.06 00.16 00.10 08.29 :31 -·00.~~2 00.2'7 00.09 013.41. 0 ....

This manual describes the methods employed by R&M Consultants for collecting water samples and measuring various parameters in the field.Included also are procedures for filtering,processing and handling samples for quantitative analysis in a laboratory . PROCEDURES At the sampling cross-section a tag line must be strung across the channel to mark the sampling locations.If possible the tag line should be left up for the duration of the season so the same sampling locations can be used in subsequent operations.Three sites are marked on the tag line for water quality sampling.The locations should be equally spaced with one site at mid-channel and the remaining two at an equal distance between mid-channel and the left and right ban k.Ten sites will be required for suspended sediment sampling.All locations must be clearly marked with flagging or paint on the tag line. All water samples are collected with a U.S.P-61-A1 Point Integrating sampler,except during the winter when frazil ice will clog this device.Then the van Dorn sampling bottle is used. Refer to the section entitled IISuspended Sediment Sampling"for a detailed description of the P-61 operation.The van Dorn sampler makes use of a "gra b ll sampling method.The sampler is opened and held underwater at a depth not less than one foot.Care should be taken to avoid creating turbulence around the sampler. When filled,the release button is pressed which closes both ends simultaneously,entrapping the water sample. Prepare a level surface and set up the YS I model 5'1 B Dissolved Oxygen meter,the YSI model 33 S-C-T meter and the VWR Scientific Model 55 pH meter.The I mhoff cones are placed in the rack built onto the equipment box.Carefully rinse out all containers used for the handling of samples. Conductivity Conductivity is measured with a YSJ Model 33 Salinity Conductivity-Temperature meter.Before an actual measurement, the sensor probe should be cooled to the temperature of the s14/j - 1 - sample.This can be done by submerging the probe in a container of river water about 15 minutes prior to measurement. To measure conductivity the sensor probe is placed in the sample to be tested.-Momentary agitation should free any air bubbles trapped in the sensor.These air bubbles must be eliminated for an accurate measurement.The instrument is standardized by adjusting the needle to coincide with the red line on the scale. The temperature of the sample is read and recorded.The temperature compensating dial on the "meter is adjusted to that water temperature.The conductivity is measured using the lowest scale on the meter.All data are recorded on the field log or a field notebook.Temperature-corrected conductivity (for a standard 25°C)is determined by applying one of the following conversion factors,where °C is the temperature of the sample. Conductivity is reported in micromhos/cm @ 25°C. The VWR Scientific Model 55 pH meter is very sensitive to cold water temperatures and moisture within the housing.Cold water temperatures affect the gel within the sensor so that the meter will require a long time to stabliize,about 15 -20 minutes per reading.The meter should only be calibrated just prior to pH measurements.The buffer solutions and sensor should be cooled to sample temperature before calibrating.Submerging the bottled buffer solutions in a container filled with river water is adequate for cooling. The pH meter is calibrated.by placing the sensor probe in the pH 7 buffer solution.Assuming the buffer solution is the same temperature as the water sample,set the TEMPERATURE dial on the meter to the temperature of the water sample.Turn the meter on and depress the push-button on the left side to illuminate the digital display.Adjust the meter to pH 7.00 with the dial labelled CALIBRATE.Rinse the sensor in distilled water,then place in the pH 4 buffer.Adjust the TEMP ERA TU REdial until the meter reads 4.00.Measurements of the water sample should be taken - - - s14/j - 2 - -immediately after calibration.Carefully rinse the sensor in distilled water and place in the sample.The meter reacts slowly so a sufficient amount of time must be allowed for stabilization. The meter reading will II s t ep "up slowly until stabilized.The most accurate pH reading is when the meter has stopped stepping up. In cold weather this may take as long as 25 minutes.Under these conditions it might be advantageous to take the pH of the "composite"instead of each individual sample. Dissolved Oxygen Since the dissolved oxygen is measured from the boat,this meter should be calibrated first upon arrival at the site.The YS I model 51 S Dissolved Oxygen meter is standardized by two methods found to be efficient in the field.For the most accurate readings the meter should not be moved once it is calibrated.Therefore,these procedures are best carried out on the boat with the meter in the same operating position as when the measurements are taken. Adjust the meter pointer to zero with the instrument turned off, using the screw in the center of the plexiglass panel.Position switch to ZERO and again adjust pointer to zero but this time with the zero control knob.Position switch to FU LLSCALE and adjust to the "15"mark on the P.P.M.scale using the full scale control knob.Allow instrument to stablize for 10 -15 minutes,without turning it off.Shake a bottle,2/3 full of distilled water,to saturate with air.Then wait until no more bubbles rise to the surface,about 10 minutes.Remove the end cap from the sensor and submerge the probe in the bottle.Set switch to READ TEMP and set the OXYGEN SOLLI BI L1TY FACTOR to correspond with the water temperature reading.Read the actual (not adjusted to sea level)barometric pressure from the barometer and record.Select the appropriate saturated water oxygen value from Figure 1. Place the sensor probe in the sample and stir (stirring is accomplished by moving the probe vertically at approximately 1-foot per second).Position switch to READ a and adjust the CALIS knob so that the pointer indicates the vafue obtained from Figure 1.The meter is now calibrated. As a check to verify the accuracy of the calibration a second method is used.Position the switch to CALIS.With the probe in the protective bottle (insure that the cloth inside the bottle is moist)to provide humid air around the membrane,the pointer shou ld set at the mark for the local elevation. If the water saturation procedure was carried out correctly,then no adjustment of the CALI B knob is necessary.If the pointer does not correspond to the local elevation,then adjust by turning the CA LI S knob.Then repeat the water satu ration method. s14/j - 3 - The instrument can easily go out of calibration if it is moved or jarred. Measure dissolved oxygen by positioning the boat at one of the three predetermined locations across the channel.It is important not to create a turbulent flow around the sensor probe,so for accurate readings the boat should be positioned upstream of the marked site and allowed to drift while the measurement is taken. Check the instrument setting of ZERO and FU LL SCALE.Remove the protective bottle and suspend the probe over the side of the boat.Set switch to READ TEMP and adjust the OXYGEN SOlUBI LITY dial to the temperature of the water indicated by the meter.Record the water temperatu re on the field data form. Agitate the sensor vertically at a constant rate.Position switch to READ 0::,and the pointer will indicate dissolved oxygen in p.p.m. Repeat tfiis procedure at the two remaining sampling locations. Percent saturation is computed by dividing the measured dissolved oxygen value by the saturated water oxygen value from Figure 1. Sampling After the measurement of water temperature and dissolved oxygen the water samples can be collected.This is done at the same three sites as used in dissolved oxygen measurement.Using the P-61 sampler,a depth-integrated water sample can be obtained. For some parameters,this method produces a more representative sample,as opposed to the grab sampling technique which can only sample at a fixed depth. To insure an adequate supply of water for field and laboratory analysis,a 3-liter container should be filled at each site.Since the P-61 can only hold 1 liter,this requires that three samples be taken at each site and combined in a 3-liter container.Care should be taken not to·aerate the water when combining these samples.When all the locations across the channel have been sampled,the remaining field parameters can be measured upon return to the bank. The pH and conductivity meters should be standardized just prior to making measurements.After calibration,the conductivity sensor and the pH sensor can be inserted directly into the first of the 3-liter containers.Depending on the temperature,a period of time should be allowed for sensor stabilization.The colder the temperature the longer the time required for an accurate measurement.Measure conductivity first since the pH sensor usually requires a longer stabilization period. s14/j - 5 - Insure the proper setting of the red line on the conductivity meter and adjust the temperature compensating dial to correspond with the water temperature.Read the conductivity with the switch set on the lowest scale.Record the value on the field data form. The pH meter needs no further temperature adjustment if the buffer solutions were cooled to sample temperature before calibration.Read the pH directly.An effort should be made to insure that the meter reading is stable and not slowly stepping up in value.Record the pH on the field data form. Transfer both sensor probes to the next 3-liter sample and repeat the measurement procedures. Stir the sample in each of the 3-liter containers so that all sediment is in suspension,then quickly transfer 1 liter of the sample to an Imhoff cone for determination of settleable solids. Note the time of the transfer to the cone.After 45 minues the sample in the Imhoff cone should be stirred to loosen any material ad herring to the side of the cone.One revolution of a stirring rod or the thermometer held against the side of the cone should be sufficient.Care should be taken not to disturb the sediment already settled to the bottom of the cone.Total settleable solids can be read after an additional 15 minutes from the time the sample was stirred.Read the settleable solids from the graduations on the Imhoff cones and report in ml/I. The sample remaining in each 3-liter container can be mixed together in a large clean bucket.After the Imhoff cone have been read I they can also be drained into the bucket with the other water quality samples.The water in the bucket now constitutes the "compositell sample. Filtering and Preservation. Prepare the filter assembly by rinsing out the container carefully and inserting a G.4S-micron membrane filter in the depression on the bottom plate.Lay the coarse fiber filter on top of the membrane filter with the rough side up.Mix the composite sample in the bucket thoroughly and pour into the filter.Using the air pump I pressurize the filter only enough to produce a slight stream of filtered water from the nozzle in the bottom plate.If,during the filtering process,the filters should break,any water already collected will be contaminated and should be discarded or filtered again. Recent quality control analysis has revealed a possible contamination fo the filtered samples by certain metals. Consultation with laboratory technicians resulted in a procedure to prepare the filters.These procedures have not been incorporated - - s14/j - 6 - - to date,however are recommended for future sample handling, even if only for a comparative analysis. The filter papers (membrane and fiber)are to be rinsed with distilled water and then be allowed to soak in more distilled water for 24 hours prior to sample collection.An alternate method is to prepare a lIblankll sample.Prepare the filter assembly with dry filter papers and run 1 quart of distilled water through it. Submit this as a sample to the laboratory for analysis along with the other water samples. The filtered water should be collected in clean,1-quart bottles supplied by the laboratory.These bottles must be marked well in reference to their contents to avoid later confusion.Table 1 lists as a guideline how each bottle should be prepared,labelled and for which parameters each will be analyzed.Preservatives are supplied by the laboratory in glass or plastic vials.After the lab bottles are filled,the acid preservatives,either H2S04 (sulfuric) or HN03 (nitric),are added to the appropriate bottles. All samples for quantitative analyses are kept ina cooler full of ice during shipment to the laboratory.The water temperature should be kept below 4°C. Table 2 lists the detection limits and methods used for parameter measurements in the field and laboratory.The references on Table 2 and on the following page should be consulted for specific descriptions of procedures. Alkalinity AI kalinity should be determined on-site in the field to avoid effects of storage and air mixing with the sample.However,if this isnJt feasible,then it would be acceptable to delay this measurement until return to camp.A separate unfiltered sample is obtained from the composite sample.The sample container must be filled to the top and tightly capped to prevent any mixture with air.Keep the sample cool along with the other water quality samples and transport to camp.AI kalinity is measured using a potentiometric titration to an end point pH.The end point pH is determined by the expected al kalinity concentrations as follows. AI kalinity (mg/I of caC03 ) 1st End Point (C)2nd End Point (D) 30 5.1 4.8 150 4.8 4.5 500 4.5 4.2 ~ s14/j - 7 - Container TABLE 1 R&M CONSULTANTS WATER SAMPLE PREPARATION Field Preparation and Label Parameters Plastic 1 quart Plastic 1 quart Plastic 1 quart Plastic 1 quart Plastic 1 quart Glass (freon rinsed) 1 quart s14/j HN03Filtered No Preservative Filtered H2S0 4Filtered H2S0 4Unfiltered No Preservative Unfiltered No Preservative Unfiltered - 8 - ICAP Scan Uranium Radioactivity I Gross AI pha Total Phosphorus Ortho -phosphate Chloride True Color Sulfate Total Nitrogen Ammonia Nitrogen Organic Nitrogen Nitrate Nitrogen Nitrite Nitrogen Total Organic Carbon Chemical Oxygen Demand Turbidity Total Dissolved Solids Total Suspended Solids Organic Chemicals ern· - ..- -. Calibrate the pH meter (see pH meter section).Obtain a 100 mi. sample in a graduated cylinder and transfer into a beaker.Fill the buret with 0.02 Normal sulfuric acid and record the volume as indicated by graduations on the buret (read at bottom of meniscus).Determine the initial pH of the sample and record. Titrate to the appropriate end points. Example:Initial pH of a 100 ml sample was measured at 6.64. The buret was filled with 0.02 N sulfuric acid to 0.36 ml as read from the graduations on the buret.The sample was obtained from the Susitna River and al kalinity was expected to be between 30 and 150 mg/I of CaC03 .The end points to titrate to are therefore,5.1 and 4.8.:A.cid is added to the 100 ml sample until a pH of 5.1 is reached.At this point a reading is obtained from the buret.The volume of acid is now 6.74 ml,therefore 6.38 ml (6.74 -0.36)of acid have been used to reduce the pH from 6.64 to 5.10.Titration continues until the pH drops to 4.8.The buret now reads 6.93,indicating that a total of 6.57 ml.of acid was required to reduce the pH to 4.8. Alkalinity is calculated as follows: Alkalinity =(2C-D)xO.02 x 50,000 =10 (2C-D) 100 where C =ml titrant to the 1 st end point. where D =ml titrant to the 2nd end point. Thus,alkalinity in example =10 [ 2 (6.38)-6.57 ]=61.9,or 62 Note:If initial pH exceeds 8.3,record the ml titrant used to reduce the pH to 8.3 and proceed as above.See page 253 in Standard Methods,15th edition,for alkalinity relationships to determine the concentrations of bicarbonate,carbonate and hydroxide alkalinity. - After receiving the quantitative analysis results from the laboratory,free carbon dioxide and hardness can be determined. Free Carbon Dioxide Using the temperature,pH and alkalinity data obtained in the field and the lab values for total dissolved solids,the free CO 2 can be determined by the nomographic method (Figure 2). ~- s14/j -9 - --------- TABLE 2 WATER QUALITY PARAMETERS ANALYSED FROM VEE CANYON AND GOLD CREEK BY R&M CONSULTANTS,INC.(1) -, Data Available Detection from the - Method(2)Umit(3)(4)U.S.G.S.
