SEWER OUTFALL STUDY
CITY OF LEBANON, NEW HAMPSHIRE
JULY 15, 1971
On July 15, 1971, personnel from Region I of the U.S.Environmental
Protection Agency, under the supervision of David Stonefield sampled
various sewer outfalls in the city of Lebanon, New Hampshire, as well
as the Mascoina and Connecticut Rivers (Figure 1 and Table 1).
Kerry Anderson and Robert Myers collected the downstream
Connecticut River samples (CN14), and David Stonefield and Paul Murray
collected samples from the remaining stations.
This study was designed to develop a case against the city of
Lebanon, New Hampshire, under 33 USC 1160.
Connecticut River
The Connecticut River, an interstate body of water, was sampled
above the Wilder Dam (CN13) and below its confluence with the Mascoma
River (CN14).
Mascoma River
The Mascoma River, an intr astate body of water, was sampled at
the Bank Street Bridge in Lebanon, New Hampshire (MSR1) and the
Route 12A Bridge in West Lebanon, New Hampshire. (MSR2)
Lebanon
The city of Lebanon, New Hampshire, including the village of West
Lebanon, is located on the Mascoma and Connecticut Rivers. Sampling
stations were established at the Taylor Street sewer outfall, (LEB1),
and the Eldridge Street sewer outfall, (LEB2), in Lebanon and the
Bridge Street sewer outfall, (LEB3) in West Lebanon. During sampling,

-------
flow from the Taylor Street sewer was 0.20 mgd and 0.03 mgd from the
Bridge Street sewer.
Sampling Procedures
Samples at stations MSR1 and MSR2 were collected with a Kemmerer-
type sampler and transferred into their storage and shipping containers.
A].]. other samples were hand dipped and collected directly in their
storage and shipping containers.
Samples for bacterial density, pH, turbidity, and nonfilcerable
residue were placed in clean, sterile glass bottles. The dissolved
oxygen samples were placed in 300 ml BOD bottles and preserved with
2rn1 manganous sulfate and 2znl of alkali azide reagent. The phosphorus
samples were placed in a quart cubitainer and preserved with 5m1 of
chloroform. The BOD samples were placed in a gallon cubitaiqer. All
samples were iced. A metal thermometer was used to obtain the sample
temperature.
The dissolved oxygen, pH and turbidity analyses were performed
in the field laboratory. The bacterial (total and feca]. coliform)
and nonfilterable samples were filtered and the bacterial sample
J ncubated in the Mobile Laborat9 y.and returned the same day with
the remaining samples to the Environmental Protection Agency Labora-
tory in Needham, Massachusetts for analyses.
Sample Identification
Each sample was tagged with one chain of custody tag giving collect-
ing agency, lab number, time, date, source of sample, collector’s signa-
ture 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, tempera-
ture of the sample, at d sampling location.
Results
The resuics of the sampling are sunmiarized in Tables 2 and 3.
