BELFAST BAY
BELFAST, NAThE
At the request of the Maine United States Attorney, the outfalla
from Maplewood Poultry and Poultry Processing (also known as Penobscot
Poultry) were sampled on November 3 and le, 1970.
Arthur Johnson and David Stonefield collected the samples and Howard
Davis was in charge of the mobile laboratory. The sampling crew assisted
in the mobile lab after the samples were collected.
Maplewood Poultry
Maplewood Poultry is located in Belfast, Maine, on the west side
of Belfast Bay between the new Veterian Memorial bridge and the old
bridge across the bay (Figure 1). On arrival at Maplewood Poultry at
1500 hours on November 3, David Stonefleld talked to Mr. Steven Glass,
plant manager. Mr. Glass pointed out the three outfalls (Figure 2) and
showedhim the effluent screens and the grease separator.
The southern most outfall (MP-0l) is a concrete pipe which Mr.
Glass said carried the waste from the picking room area where the
birds were killed and plucked. The effluent was blood colored and
varied markedly in quantity.
The middle outfall is located below high water mark just north of
an old pier. Mr. Glass said that the corrugated steel pipe carries
melted ice from the floor drains in the preparing room. This had the
smallest flow of the three outfalls.
The northern most outfall (MP-03) is a corrugated steel pipe which
carries from the eviscerating area. This waste is the largest of the
three effluents and is passed through screens and a grease separator
before it is discharged.

-------
Two samples were collected at each of the three outfalla on
November 3 - one for bacteria and, one for a general na1yais. The
general sample was analyzed for pH, color, turbidity, settleable solids,
and suspended solids. The temperature of the effluents was also obtained,.
On November 1 the three outfaU.s were sampled for BOO 5 and oil-grease
analysis. The temperature of the sample was again recorded.
Poultry Processing
This plant is also located on the west side of Belfast Bay in
Belfast, Maine. It is about a half mile south of Maplewood Poultry
Plant (Figure 1). Upon arrival at the plant at 1600 hours on November 3,
David Stonefield learned from Mr. Gilbert Knight, plant manager, that
the plant had shut down at lli 3O hours. Mr. Knight showed the FWQJi
representatives the source of the waste and the location of the outfall.
He said that the plant would start operation at 0700 hours on November i.
The samplers decided to return to collect the samples.
The outfall is located at the low water mark of Belfast Bay near
the salt water pump house for the condensers (Figure 3). Two pipes
were discharging to the Bay. The northern most outfall appeared to be
from the condensers. Since the e:ffluent was not colored and did not
carry many solids, it was not sampled. The southern outfall effluent
was yellowish-red in color. Four samples - bacteria, BOD, oils and
greases and a general sample - were taken on Wednesday morning, November
ii. All were returned to the mobile laboratory.
Samnie Identification
Each sample was tagged with two tags - one sample tag giving lab
number, station, date, time, collector and a diagram of the sampling
-2 -

-------
location; and one chain of custody tag giving collecting agency, lab
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 preriumbered field data card was filled out
for each collection time to record weather conditions and the temperature
of the sample.
All samples were returned to the mobile laboratory, located at
the Belfast Motor Inn, where the BOD 5 and oil-grease samples were
prepared for return to the NEBO laboratory for analysis. The suspended
solids and. bacteria samples were filtered in the mobile laboratory and
returned to the NEBO laboratory for completion of the analysis. All
other tests were performed in the mobile laboratory.
Results
Table I smmn -rizes the results of the effluent analysis. These
results show that two of Maplewood Poultry effluents, -Ol and -3,
and the ultry Processing effluent, PP.01, were highly colored, turbid
and contained large quantities of suspended solids. The oil-grease
content and the BOD of these three effluents were above that of normal
raw sewage. The bacterial content of MP-Ol was extremely high, similar
to raw sewage.
The results of analysis on the other outfall from Maplewood Poultry
(MP-2) were similar to those expected for diluted raw sewage.
