INTRODUCTION
Purpose
The Federal Water Pollution Control Administration (FWPCA),
Pollution Surveillance Branch, maintains a system of water quality
sampling stations on interstate waters in the Northwest Region.
Throughout the year the water samples are collected at these stations
and analyzed, and the data are used to evaluate water quality. Know-
ledge of conditions peculiar to these stations is valuable in the
evaluation of the data obtained. This study documents conditions
at Station No. 153018 located on the Snake River seven miles down-
stream from the Lewiston-Clarkston bridge (Fig. 1). Diurnal and
spatial variances occurring at the station were observed during a
24-hour period.
On February 25 through 29, 1969, a similar study was conducted
at the station which was then located two miles upstream from the
present Station No. 153018. This survey showed that an incomplete
mixing condition is present at that location. As a result, the station
was relocated at the present site to allow more mixing time and to
take advantage of more homogenous sampling conditions.
Objectives
-The objectives of the study were to answer the following
questions:
-------
FIGURE I. General Location Map
-------
1. Does a uniform cross-section pattern exist at the sampling
site?
2. What are the diurnal changes occurring in water quality
at the station?
3. What are the influencing factors on water quality at this
location?
Authority
Authorization for this study was from the Federal Water Pollution
Control Act (33 U.S.C. et seq.) as amended. The study was performed
by the Technical Assistance and Investigations Branch of the Office
of Technical Programs as requested by the Pollution Surveillance
Branch.
Sampling Program
1. Six water samples were collected every two hours for a 24-
hour period. The initial sample collection was at 1200 hours (noon)
on July 29, 1969, with the final samples taken at 1200 hours on
July 30, 1969. Samples were also taken at six sites extending upstream
from Station No. 153018 to above the confluence of the Clearwater River
(Fig. 1).
2. Pre-survey soundings confirmed that the cross-section at
Station No. 153018 had a uniform depth of 17.0 feet. Three equally-
spaced sampling points were selected across the river. The sampling
-------
points were located by means of airplane markers on a gauging car
wire extended across the site. Samples were taken at 5-foot and
15-foot depths at each of these sampling points.
3. The following analyses were performed on the samples: pH,
specific conductivity, dissolved oxygen, total alkalinity, total
coliform, fecal coliform, and turbidity.
-------
SUMMARY
Findings
1. The river had a uniform depth of 17 feet at the transaction
location.
2. The only discrepancy in cross-section station parameter
values occurred in bacteriological concentrations and turbidity
measurements.
3. The diurnal temperatures ranged from a high at 1200 hours
(noon) of 23.5° C-/ to a low of 19.1° C at 0600 hours (Fig. 2).
4. The percent dissolved oxygen saturation values displayed
a high of 115 percent at 1800 hours, decreasing to a low of 86 per-
cent at 0600 hours, and then rising again (Fig. 3).
5. The dissolved oxygen concentration pattern indicated a high
of 10.0 milligrams per liter (mg/1) at 1800 hours, then dropped to
a low of 7.8 mg/1 at 0600 hours (Fig. 2).
6. The pH ranged from 7.5 to 8.5. Two maximum peaks occurred,
the first at 1600 hours with an 8.4 value, and the second at 1800
hours with a value of 8.5. The minimum was 7.5 at 1200 hours (Fig. 4)
7. Specific conductivity values ranged from a maximum of
190 micromhos per centimeter (jumho/cm) at 1400 hours, to a low of
158 Ximho/cm at 0600 hours (Fig. 4).
8. The bacteriological concentration count was the only param-
eter "that did not display the general pattern of higher values occur-
l/ All parameter values quoted in the Findings are bi-hourly
averages for the six cross-section samples.

ring from 1200 hours to 2400 hours, with the lower values present
during late night and early morning (Fig. 5).
9. The total and fecal coliform densities displayed two maxi-
mum peaksone of 3300 total coliforms per 100 milliliters
(TC/100 ml), and 160 fecal coliforms per 100 milliliters (FC/100 ml)
at 2400 hours, and another at 0600 hours with values of 3880 TC/100 ml
and 196 FC/100 ml (Fig. 5). The increases were both 100 times the
low values of 333 TC/100 ml and 1 FC/100 ml recorded at 1600 hours.
10. The flow measurements for the study period show an average
hourly flow of 22,500 cubic feet per second (cfs) . The data, as
obtained from the U. S. Geological Survey, are shown in Table 1.
Conclusions
1. The sampling station is located far enough downstream from
pollution sources to allow sufficient mixing to produce optimum
sampling conditions.
2. The differences in the diurnal values for coliforms and
turbidity among the three cross-section sampling locations indicate
incomplete mixing of solids . Data from previous surveys indicate
this condition exists for an undetermined distance downstream from
the sampling station.
3. With the exception of the bacteriological counts, the diurnal
parameter patterns displayed higher values between 1200 hours and
2000 hours. The minimum recorded values appeared between the hours
of 2400 and 1000.

4. The upstream factors that would have an influence on water
quality are:
a. Potlatch Forest, Inc., manufacturers of lumber, pulp,
paper, and fuel products, discharges effluent into the Snake River a
quarter of a mile above the confluence of the Clearwater River.
b. The Lewiston city sewage treatment plant discharges
effluent into the Clearwater River 0.8 miles above its confluence
with the Snake River.
c. The Clarkston city sewage plant is located on the
Snake River, one mile below the confluence of the-Clearwater River.
d. Asotin sewage treatment plant discharges into Asotin
Creek, just upstream from the mouth.
e. Seabrook Farms Co. and Smith Frozen Foods, both
processors of peas, are located in Lewiston and both have discharges
into the Snake River.
f. Meats, Inc., and Bristol Packing Co., located in
Clarkston, discharge floor drainage and kill blood directly into
the Snake River.
g. A few feedlots are located adjacent to the rivers above
and below the cities of Lewiston-Clarkston.
Recommendations
1. Sampling Station No. 153018 should be maintained as a
permanent water quality monitoring station.
-------
13
2. The samples should be collected on the south side of the
transect station to provide better access and decrease travel time.
3. To maintain consistency, samples should be collected be-
tween mid-morning and mid-afternoon.
4. If feasible, during the low-flow periods, two samples
(one on the north side and one on the south side) should be collected
to confirm river mixing conditions.
5. An extensive study should be conducted, concentrating on
the significance of bacteriological contributors located upstream
from the sampling site.
-------
14
STATION LOCATION AND DESCRIPTION
The station is located at river mile 132.9 of the Snake
River, seven miles below the towns of Lewiston, Idaho and Clarkston,
Washington. At this point, the Snake River turns westward after
flowing through Hells Canyon (Fig. 1).
The specific location is:, lat 46°25'30", long 117°10'30".

SAMPLING AND ANALYTICAL METHODS
Sampling Methods and Schedule
Water samples were collected every two hours during the 24-hour
period. Collection was made at three pre-determined cross-section
points, with two vertical profile samples taken at each of the three
points. The samples were obtained using a Kemmerer' sampler. A
single "haul" provided enough water to fill containers for chemical
(dissolved oxygen, conductivity, pH, alkalinity, and turbidity) and
bacteriological (total and fecal coliform) analyses.
Turbidity samples were shipped to the Federal Water Pollution
Control Administration Laboratory in Portland, Oregon for analysis.
Dissolved oxygen samples were chemically stabilized at the time
of collection for titration upon return to the field laboratory.
With the exception of turbidity measurements, all of the analyses
were performed in a 17-foot enclosed laboratory trailer stationed
near the sampling point.
Analytical Procedures
The following laboratory methods were used for analysis:
pH was determined with a Beckman Zeromatic Model pH meter.
Specific conductivity analyses were performed with an Industrial
Instruments Model RC-16-B2 conductivity bridge.
Dissolved oxygen samples were titrated for quantity, using the

Alsterberg (Azide) modification of the Winkler Method as found in
"Standard Methods." (1).
Alkalinity was determined by titration with a Hach Model DL-ER
portable laboratory.
Turbidity was measured at the Portland Laboratory with a Hach
Model 1860-A Turbiditimeter.
Fecal coliform determinations were conducted using the membrane
filter method according to the procedure described by Geldreich (2).
In studies by Geldreich (3) this method was confirmed as comparable
to the most probable number method for fecal coliform as described in
"Standard Methods" (1).
Total coliform densities were measured by the membrane filter
method technique in "Standard Methods" (1).
All the bacteriological samples analyzed were incubated and
counted in the field.
-------
17
DISCUSSION
The cross-section parameter values for the sampling points are
given in Figures 6 through 9. With the exception of bacteriological
and turbidity values, the transect discrepancy is minimal. The
cross-section pattern shows no location preference as to high or low
values.
The cross-section averages for total and fecal coliform con-
centrations (Fig. 8) show the increasing values beginning at
2000 hours, then dropping again to a low at 1000 hours the next day.
The patterns also indicate both values decreasing "at 0200 hours.
This pattern could be attributed to treatment plant operations up-
stream, with the daytime loads being detained in the plant system and
flushed out with the evening high flows. The times of high concen-
trations (considering flow time), also coincide with clean-up opera-
tions from upstream meat and industrial processors.
The conductivity, pH, temperature, dissolved oxygen and percent
saturation values all displayed an average (cross-section) diurnal
pattern of higher values occurring between 0800 hours and 2200 hours
(Fig. 6, 7 and 9). This pattern reflects the daytime schedule of
industrial activities and the processes of photosynthetic organisms
present in the river.
Examination of the data reveals that at times during the study
total coliforms, dissolved oxygen, and temperature did not meet the
Washington State Water Quality Standards'^' which state:

The dissolved oxygen values were below the Washington State
Standards for only one sampling period. The total coliform concen-
trations were in excess of the Washington State Standards during
the entire study. Temperature was in violation of the Standards
during 75 percent of the study period.
Municipal waste sources in the lower Snake basin are concen-
trated in the Lewiston service area, where primary is the prevail-
ing level of waste treatment. A total organic waste load equivalent
to that from a population of 34,900 is discharged from the service
area. The city of Lewiston accounts for about 30,000 population
equivalents (PE). The Idaho Water Quality Standards (5) call for
secondary x^aste treatment at Lewiston by June 30, 1970. In
addition, the Washington Water Quality Standards (4) require in-
stallation of secondary treatment, disinfection facilities, and
proper outfalls at Clarkston and Asotin by March 31, 1970.
The most significant source of waste in the area is the
Potlatch Forest Industries plant located in Lewiston. A complex of
.manufacturing operations, the plant includes a large lumber mill, a
plywood plant, wood fabricating facilities, and an integrated pulp,
paper, and paperboard mill. The pulp and paper plant provides no treatment
-------
23
of wastes, and available information on plant operations indicates
that it has a waste-to-product ratio well above the norm for modern
sulfate pulping plants. A total organic load of about 432,000 PE
is discharged to the Snake River. The Idaho Water Quality Standards
require that Potlatch Industries provide primary treatment.
Seabrook farms, Inc., a pea and potato processing plant at
Lewiston, also discharges without x^aste treatment. An organic load
of about 50,000 PE is discharged into the Clearwater River. The
Idaho State Water Quality Standards(5) require that primary treatment
be installed and connected to the city collection system by June 30,
1970.
Two meat packing plants in Clarkston, Washington have inadequate
treatment. Bristol Packing Co. and Meats, Inc., discharge a total
organic load of about 5,300 PE to the Snake River. The Washington
State Standards(^' call for primary treatment at these plants by
March 31, 1970.
Agricultural animal waste discharges in the Lower Snake are a
significant source of coliform bacteria and a source of some of the
biochemical oxygen demand. The estimated organic waste potential of
the animal population is equivalent to that from a population of
3.2.million people. An estimated 95 percent of the wastes generated
are reduced by deposit to the land and natural decomposition, so
that "about 160,000 PE eventually reach waterways. Grazing and feed-
ing farm animals are considered to be a major waste source, but their
-------
24
impact on water quality is difficult to determine. Stream bank feed-
lots and dairies are situated at a number of points, providing an un-
restrained source of serious bacterial contamination. Less concen-
trated but significant influences are pasture and grazing areas along
the water courses and drainage ditches. In many areas the stream
banks are not fenced, allowing the animals unrestricted access to the
water.
