SEWER OUTFALL STUDY
Town of Hartford, Vermont
(Villages of White River Junction, Hartford, and Wilder)
July 15, 1971
On July 15, 1971, personnel from Region I of the Environmental Protection
Agency (EPA) under the supervision of David Stonefield, sampled the Town
of Hartford, Vermont for possible enforcement action. Samples were col-
lected at various sewer outfalls in the Town of Hartford, the influent
and effluent of the Wilder Water Pollution Control Facility and the
Connecticut and White Rivers (Figure 1 and Table 1).
Messrs. Stonefield and Murray collected samples from the ‘Connec ticut River’
above the Wilder Darn (CN13) and from the Wilder Water Pollution Control
Plant, (HRF1 & HRF2) .Mesars Anderson and Myers collected the remaining
samples.
White River
The White River, an intrastate body of water, was sampled at the Hart-
ford Village Bridge (WHR1) and the Railroad Bridge just above the con-
fluence of the White and Connecticut Rivers (WHR2)
Connecticut River
The Connecticut River, an interstate body of water, was sampled at the
upstream side of the Wilder Darn (CN13) and below the confluence of the
Mascoma and Connecticut Rivers (CN14).
White River Junction
The Village of White River Junction is situated at the confluence of the
White and Connecticut Rivers. Samples were collected at the Rail-
road Yard sewer outfall (HRF4), the Bridge Street sewer outfall (HRF5)
and the Harrison Avenue outfall (HRP6).During the sampling, flows
through the outfalls averaged 0.40 million gallons per day (MCD), .11
MCD, and 0.03 MCD respectively.
Wilder
The Village of Wilder is situated on the Connecticut River and has a
primary water pollution control plant. The influent and effluent of
this plant were sampled (HRFL & 11R12 respectively). At the time of
the sampling, the flow through the WPC plant averaged 0.22MCD.

-------
Hartford
The Town of Hartford also contains the Village of Hartford. In the
Village, the Maple Street sewer discharge was sampled at its outfall
to the Connecticut River (HRF3). At the time of sampling, the flow
through this outfall averaged 0.07 MCD.
Sampling Procedures
The Connecticut River at the Wilder Dam, and the influent and effluent
samples of the Wilder Water Pollution Control Facility, were collected
with a Kemmerer-type sampler and divided into their storage and ship-
ping containers. All other samples were hand dipped and collected
directly in their storage and shipping containers.
The bacterial samples were filtered and incubated in the Mobile Field
Laboratory for both total and fecal coliforms. The solids samples
were filtered in the Field Laboratory for nonfilterable residues while
other samples were analyzed in the Field Laboratory for DO, pH and turbidity.
All other samples were preserved as necessary and returned the same day
by car to the Environmental Protection Agency Laboratory in Needham,
Massachusetts for analysis. All Field Laboratory analyses were conducted
under the supervision of. Howard Davis.
One bacterial bottle sample was used for bacteria, solids, turbidity,
and pH analyses; one gallon cubitainer for 5-day BOD analyses, one
quart cubitainer for total phosphorus analysis; and one 300 ml bottle
for DO analysis.
The dissolved oxygen samples were preserved with 2ml manganous sulfate
and 2m1 alkali azide reagents, and the phosphorus samples preserved
with 5m1 Chloroform. Al]. samples were iced. Sample temperatures were
obtained with metal thermometers.
Sample Identification
Each sample was tagged with one chain of custody tag giving collecting
agency, lab number, time, date, source of sample, collector’s signature
and title, witness’s signature and title, plus information on the
transfer of the sample. In addition, a prenumbered field data card was
filled out for each collection time to record weather conditions, temp-
erature of the sample, and sampling location.
Results
The results of the sampling are summarized in Tables 2 and 3.
