SUSITNA HYDROELECTRIC PROJECT
ANNUAL REPORT
WATER QUALITY ASSESSMENT
1 -INTRODUCTION
This report presents a summary of work accomplished pertaining to
water quality by R&M Consultants,Inc.during the first year of
the Susitna Hydroelectric Project and recommendations for the
second year.
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.

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.

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.

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.

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.

Chemical &Geological Laboratories of Alaska,Inc.,has been contracted
to provide laboratory analyses.They are one of two private labora-
tories in Alaska certified by the Alaska Department of Environmental
Conservation to provide water quality analyses.The parameters,
methods,-,and detection limits follow:
~-
c)Recommended method outlined in the Federal Register f Vol.44,
No.233,pt.III,Appendix IV
d)Following accepted .method outlined by G.K.Turner Associates,
e)Reported as picocurie/liter
"
f)Recommended method outlined in the Federal Register,Vol 38,
No.75,Pt.II,Appendix A.
5)REPORTING
Data will be compiled to provide a range and mean for each parameter
during each of three seasons.The seasons and their respective
definitions are:breakup -from the time ice begins to break up until
recession of spring runoff,summer -from the end of breakup until the
water temperature drops to essentially OOC in the fall,and winter -
from the end of summer until breakup begins.
The format for data collected will consist of an alphabetical listing of
field parameters followed by an alphabetical listing of laboratory para-
meters..There will be one page per sample site and the heading will
have the site,date,·sample time,personnel doing the sampling,and
other relevant observations.

ADDENDUM
The following paragraph should be included in the Annual Report
at the end of Section 3,Recommendations for 1981 Water Quality
Data Collection:
The concentrations of suspended sediment during the winter
were extremely low at both sites (and have been
historically,according to USGS figures).Hence,depth-
iintegrated sediment sampling will be discontinued after
freeze-up in 1981.However,the total suspended solids
data reported with the water quality parameters will
continue to be collected.
