WALLOOMSAC RIVER STUDY
1977
OVERVIEW
The State of Vermont Agency of Environmental Conservation (AEC)
requested assistance of the U. S. Environmental Protection Agency's
(EPA), Region I, Surveillance & Analysis Division (S&A) and Systems
Analysis Branch (SAB) in modeling a portion of the Wailoomsac River
from Bennington, VT to just above its confluence with the Hoosic
River. The modeling effort was divided among the three participants
as follows:
1. AEC - Provide time of travel information at two flow regimes
and cross sectional data.
2. S&A - Provide 3 days of ambient and source water quality data.
3. SAB - Provide modeling capabilities based on information obtained
by the AEC and S&A.
S&A was subsequently asked by SAB to collect additional time of
travel and hydrology information.
With the exception of chlorophyll a_ and pheophytin a_ results, all
data requested of S&A has been sent piecemeal to the AEC and SAB.
This report is intended to summarize all the data under one cover
including the chlorophyll a_ and pheophytin a_ results.
-------
GENERAL
From August 23, 1977 to August 26, 1977, S&A personnel conducted
a water quality and major discharge study on the Walloomsac River from
just below the confluence with Roaring Branch in Bennington, VT to the
Route 22 bridge in North Hoosick,NY. The sample station locations are
shown and described in Figure 1 and Table 1 respectively.
On November 10, 1977, S&A personnel conducted a time of travel
study from the dam just above the Henry Covered Bridge in Bennington, VT
to the Columbia Corporation Dam in Walloomsac, NY.
AMBIENT WATER STUDY
S&A personnel collected ambient water samples from eleven locations:
nine on the main stem of the Walloomsac River and two on major tributaries.
Samples collected from two of the stations on the main stem were analyzed
for dissolved oxygen only, while water samples collected from the tribu-
taries and other main stem stations were analyzed for the parameters
sjiown in Table 2. The number and types of samples collected at each
ambient station are also shown in Table 2.
The ambient sampling was split into three 8 hour crews. Each crew
made one sample run to record water temperature and collect the necessary
samples to perform the types of analyses presented in Table 2 and one
run for water temperature and dissolved oxygen information only.
Composite samples consisted of equal aliquots of sample from the first
daily run of each crew. These composites then represented a 24 hour
composite made up of three samples collected at approximately 8 hour
intervals.

-------
Ambient water results are presented in Table 3. Long term BOD results
are presented in Table 4.
In addition to the sampling effort, temperature - dissolved oxygen
recorders were set up at three locations during the study. Table 5
indicates the recorder locations and lists the results.
Flows during the study period were obtained from the U.S. Geo-
logical Survey gage located at river mile 9.99 (kilometer 16.08)
approximately 0.02 miles (0.03 kilometers) downstream from the Henry
Covered Bridge. These flows are given in Table 6.
MAJOR WASTEWATER DISCHARGES
Most of the major discharges in Vermont having access to the
Walloomsac River and its tributaries discharge into the Bennington
Wastewater Treatment Facility (WWTF). The only other major Vermont
discharger is Fairdale Farms, Inc. which discharges its treated waste-
water to an unnamed tributary which joins the Walloomsac River just
above the Bennington, VT WWTF discharge. Columbia Corporation, a
paper company discharging treated"wastewater ,into. th£..Walloomsac River
±n''Walloomsac N.Y. was also sampled.
Wastewater sampling consisted of using automatic samplers to
collect 24 hour composite samples. In several instances, the samplers
malfunctioned and grab samples were collected. Table 7 lists the
results of the wastewater sampling effort and indicates whether the
sample was a 24 hour composite or grab. Table 8 lists WWTF flows.
TIME OF TRAVEL AND OTHER HYDROLOGICAL INFORMATION
To supplement data provided by the AEC, S&A conducted one time
-3-
-------
of travel study on November 10, 1977 from the dam just above the
Henry Covered Bridge in Bennington, VT to the Columbia Corporation
Dam. The results of this study is attached as Appendix I. On Nov-
ember 9, one cross section was determined and notes made relative
to the physical appearance of the river seen by car from Paran Creek
in Bennington, VT to the Columbia Corporation Dam. This information
is included as Appendix II.

JECT: vfalloomsac River Time of Travel Study
FROM: Donald P. Porteous
Sanitary Engineer, Water Section
TO: Allen Ikalainen, Acting Chief
System Analysis Branch
Attachment 1 contains the results of our time of travel study of
November 10, 1977 on the Walloomsac River. When comparing our
results with those supplied by the Vermont AEG in their letter of
October 06, 1977, please note that the station designations and the
absolute mileage between stations are different. Taking these
factors into account, the times of travel appear to be compatible.
Also, to clear up the station designations used by EPA and the AEG
during these studies, please see Attachment 2.
If you have any questions, please call me.
