MUNICIPAL WASTE SURVEY
OILMAN, VERMONT
AND CONNECTICUT RIVER
June 30, 1971
On June 30, 1971, Ray Thompson, sanitary engineer; Kerry Anderson,
aquatic sample collector; Robert Atwood, engineering trainee; and
Robert Myers, student aide, collected samples of the sewer outfalls and of
the Connecticut River in Oilman, Vermont. Howard Davis was in charge of
the mobile field laboratory. Mr. Thompson aided Mr. Davis in the analyses.
The location of each sampling station is shown in Figure 1.
Gilman, Vermont
The village of Gilman occupies some 500 acres along the west bank
of the Connecticut River. The existing sewer system is composed of some
9,300 feet of pipe discharging approximately 0.065 ingd (million gallons
per day) of untreated sewage into the river from a number of outfalls
spread over some 1,200 feet along the river bank.
Sampling Information
Figure 1 shows the two municipal outfalls sampled (CMV—l) and (GNV—2)
as well as the outfalls of the Georgia—Pacific Corporation located in
Oilman and the two river stations (CN—03 and CN—04). Table 1 presents
the location of the stations.
The mobile field laboratory crew conducted tests for dissolved oxygen,
pH, and bacteria, plus filtered for nonfilterable residue. The remaining
samples including the filtered residue samples were returned to the
Environmental Protection Agency Laboratory in Needham, Massachusetts, for
analyses.

-------
Sampling was done by two different techniques. The first technique
used was filling the storage and transport containers directly from the
sampling source by dipping the container. This was done at Stations CN—03,
GMV—l, and GNV—2. The second method involved using an initially clean
3—liter kenunerer—type sampler. The instrument was first thoroughly washed
with sample water prior to sample collection. The sample was transferred
to the storage and transport container. This method was used at river
Station CN—04.
All stations were sampled three times at approximately two hour
intervals starting at 0700 hours. All sample containers were either one
gallon or one quart plastic cubitainers except those for bacterial and
dissolved oxygen analyses samples. Bacteria sample bottles and DO sample
bottles were used respectively for these samples. All samples were preserved
according to EPA standardrmethods.
Sample Identification
Each sample was tagged with one chain of custody tag giving collecting
agency, laboratory number, time, date, source of sample, collector’s
signature and title, and 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,
the temperature of the sample and the sampling location.
Results
Tables 2 and 3 stnnmnrize the results of the laboratory analyses. At
the outfall GMV—l, based on a calculated flow rate of 33,200 gallons per
day and measured effluent concentrations, the loading rates are 23.2
pounds per dayorganic matter measured as BOD 5 (5—day biochemical oxygen

-------
demand), 14.7 pounds per day suspended solids measured as total non—f ilter—
able residue, and 0.75 pounds per day total phosphorus. This discharge
has a total coliform bacterial density ranging from 420,000/lOOmi to
4,500,000/lOOthi which is indicative of untreated domestic sewage.
At outfall GMV—2, again based on a calculated flow rate of 34,140
gallons per day and measured effluent concentrations, the loading rates
are 42.6 pounds per day BOD 5 , 41 pounds per day suspended solids, and 4.15
pounds per day total phosphorus. This diécharge also contains a total
coliform bactçrial density indicative of untreated somestic sewage, i.e.,
in excess of l6,000,000/lOOml.
Stream sample analysis does not indicate the full effect of said
discharges to the Connecticut River because of the close proximity of
the Gilman Dam. However, an increase in downstream concentrations of the
measured parai ieters can be observed in many cases.
The combined loading rate8 of these two discharges is:
BOD 5 : : loading rate 65.8 lbs./day
Suspended Solids 55.7 lbs./day
• Total Phosphorus 4.9 lbs./day
Since thi village of Gilman discharges untreated domestic wastevater
through various other outfalls (Figure 2),rit can be said that actual
loading rates are in excess of those tabulated.
