INTRODUCTION
At the request of the New Hampshire Water Supply and Pollution
Control, the U.S. Environmental Protection Agency’s (EPA) Surveillance
and Analysis Division conducted time of travel studies and water
quality studies on the Spicket River. New Hampshire considers
the Spicket River basin to be a priority basin which requires assigning
waste load allocations to polluters discharging to the basin. EPA
was requested to collect hydrologic and water quality data which
could be used to prepare a mathematical model of the river. Using
the model, the state plans to allocate loads. This report will deal
with the studies and the field data generated.
Abbreviations used in this report are defined in Table 1 and
station locations are described in Table 2.
BACKGROUND
The Spicket River rises as the outflow from the Arlington Mill
Reservoir, Salem, New Hampshire, and flows southerly 14.5 kilometers
(9.0 miles) to the Massachusetts — New Hampshire state line and then
another 8.5 kilometers (5.3 miles) south through the cities of Methuen
and Lawrence, to the Merrimack River (see Figure 1).
New Hampshire’s water quality standards assign Class B water
quality criteria to the entire portion of the Spicket River in New
Hampshire. The Massachusetts standards assign a Class B criteria
-------
2
from the Massachusetts — New Hampshire state line to the dam at Stevens
Pond in Lawrence. From the darn to the Merrimack River, Class C criteria
were adopted. The respective criteria are shown in Tables 3 and 4.
New Hampshire’s concern lay with the portion of the river from
the Salem, New Hampshire, wastewater treatment plant (RK 10.1 (RM 6.3)]
to the Massachusetts — New Hampshire state line. Because EPA felt
that the effects of the treatment plant’s discharge would continue
downstream in Massachusetts, the studies encompassed the Massachusetts
portion of the river as well as New Hampshire’s area of interest.
WASTE SOURCES
The only reported point source discharge to the Spicket River
in New Hampshire is the Salem wastewater treatment plant. The Salem
plant uses trickling filters to achieve secondary treatment and discharges
approximately 3,400 m 3 /day (0.9 tngd) of chlorinated effluent. During
the sununer months, the plant receives increased flows and organic
loadings from Canobie Lake Park (a recreation facility) and Rockingham
Park (a horse track). During this period, BOD 5 loadings to the plant
range between 180 — 240 mg/l. The plant discharges an effluent BOD 5
of 20 — 40 mg/l. During the study period, the plant began construction
of another trickling filter which is to be used in series with the
existing filter.
Other potential waste sources exist in the New Hampshire basin
area. The shores of Arlington Reservoir are heavily populated and
subsurface waste disposal may be introducing substantial nutrient loads
to the reservoir and the river. Just upstream from the treatment
-------
3
plant, the river bank is heavily commercialized. Runoff from parking
lots drain to the river, and illegal waste discharges are suspected.
Other potential sources of pollution are runoff from the horse yard
area at Rockingham Park and unknown sources along Policy Brook, a
tributary which enters the Spicket River at RK 8.8 (RN 5.5).
In Massachusetts, the banks of the river are highly developed,
and many undetected and unreported discharges may exist. Also, urban
runoff may contribute a significant waste load.
During the studies, the crews made several observations:
1. 011 slicks were visible at and downstream from the Massachusetts’
Route 113 Bridge in Methuen (Station SPKTO5, see Figure 1).
Upstream from the bridge, the east bank showed indications
of recent oil dumpings.
2. The waters of Stevens Pond are used as cooling water for
the condenser tubes at the Arlington Mill’s power plant and
then returned to the pond. Water is also withdrawn from the
pond for air conditioners in the Arlington Mill complex. This
water is discharged downstream from the Stevens Pond Dam.
3. Combined sewers and possibly a sanitary sewer spews wastes into
the Spicket River at the bridge near the Lawrence General Hospital
(Station SPKTO8).
During the study, no attempt was made to isolate and characterize
other pollution sources discharging to the river.

HYDROLOGY
Physical Characteristics
The Spicket River drops approximately 28 meters (95 feet)
during its 10.1 KM (6.3 RN) course from the Salem Wastewater Treatment
Plant to the Merrimack River (see Figure 2 for approximate river
profile). Three dams, operated as run—of—the—river dams, are in
this stretch of the river. Their locations are shown in Figure 1.
Upstream from the uppermost dam (RK 5.8 (RN 3.6)] the river has a
very flat gradient and meanders greatly except for a 1.3 kilometer
(.8 mile) portion which was channeled during the construction of
highway 1—93. The channel has sharply cut banks and a relatively
uniform width and depth.
Downstream from this dam, the water tumbles over a natural
falls and the stream bed is littered with rocks which break the
flow and increase aeration. The gradient increases and correspondingly
the flow becomes more shallow.
The middle dam [ RK 5.0 (RN 3.1)) is broken at the east bank.
Thus, the water channels to that side and then flows into a channeled
bed to Stevens Pond.
The last dam on the river forms Stevens Pond. The pond has
a surface area of approximately 43,700 square meters (10,8 acres)
and a storage capacity of approximately 52,200 cubic meters (42.3
acre — feet).
Downstream from the Stevens Pond Dam the river is channeled
and drops quickly to the Merrimack River. The river bed is littered
with rocks up to 0.3 meters (one foot) in diameter. Typical cross sections
of the river are shown in Figures 3 and 4.
-------
5
Flow
There are no established gaging stations on the Spicket
River. The only gaging records available are estimates provided
by the Salem wastevater treatment plant operator. Based upon his
estimates, the seven day one—in—ten—year low flow immediately upstream
from the effluent is assumed to be 0.1 m 3 fsec (3.5 cfs).
Arlington Mills, a factory in Lawrence, Massachusetts, exercises
some flow control on the river. The mill controls water releases
from Arlington Mill Reservoir in Salem, New Hampshire. As previously
stated, the mill uses water from and returns heated water to Stevens
Pond. The net effect is that the pond temperature increases until
the waters are inefficient for use in the condenser tubes. When
this temperature level is approached, the mill releases water from
Arlington Mill Reservoir to replace the high temperature waters
in Stevens Pond.
ThE STUDIES
Hydraulic Studies
To provide the requested data, EPA performed two time
of travel studies. Time of travel studies are used to determine
the time it takes for a water course to transport a suspended or
dissolved substance from one point to another at various stages
of flow. If two studies are conducted when the stages of flow are
in or close to the same order of magnitude, it is possible to interpolate
between or extrapolate short distances from data points obtained
and determine relatively accurate travel times at other flow stages.
-------
6
EPA conducted time of travel studies May 7 — 9 and July 15 — 17,
and 25 and 26. During the study periods, the flows were stable and
contained within the natural banks, i.e., no backwaters. During the
July studies, some local thundershowers occurred but dry ground conditions
minimized runoff and any change in flow, attributable to the rain, was
imperceptable. For purposes of the time of travel studies, the Hampshire
Roads bridge at the Massachusetts — New Hampshire state line was the
primary gaging station. Other sites were gaged randomly. Flow data are
shown in Table 5.
The study area was broken into six reaches for determining times of
travel. These reaches are defined in Table 6. The resultant time of
travel data points for these reaches are plotted on Figures 5 — 9.
Water Quality Study
The water quality study ran from July 17 — 19. During the
study, the crews attempted to follow a “slug” of water as it travelled
downstream. The crews sampled the river upstream from the outfall
(SPKTO1), at the outfall (SWWTP), and downstream from the outfall
after mixing (SPKTO2) to determine the chemical characteristics of the
initial unit of water. Seven other sampling stations were selected
downstream. The stations are listed in Table 2. In theory, if this
same unit is characterized as it travels downstream, one can determine
the combined hydrological and physical effects of the river and the
time related biological effects upon the water unit.
Using data obtained during the dye studies, the crews established
times for sampling the water unit at downstream locations. The crews
determined also that the unit sampling concept was not valid in or
-------
7
downstream from Stevens Pond. During the July dye studies, the dye had
dispersed throughout the pond indicating that Stevens Pond acts as a holding
and mixing basin. Thus, a plug flou concept is not valid downstream from
the pond during low flows, and saripi.ing was at random time intervals.
At all stations except SWWTP and SPKTO2, three grab samples were
collected one hour apart. At SPKTO2, the field crew collected two grab
samples and a six hour composite sample comprising six grab samples collected
at one hour intervals. Temperature and pH were determined on each grab
sample. At SWWTP, the crew collected a six—hour composite sample consisting
of six grab samples collected at one—hour intervals. Three of the grab
samples were used also as bacteriological samples. Temperature and p11 were
determined on each sample increment. The parameters sampled and analytical
results from each station are shown in Tables 7 and 8.
On July 18, field crews made two runs to develop temperature and DO
profiles along the river. The data are presented in Table 9, and the
profiles are shown in Figures 10 and 11. During one of these runs, the
crew developed vertical DO profiles as well. These data are in Table 10.
Figure 12 shows the average DO and temperature profiles developed from the
regular sampling program.
During July 22 — 26, DO temperature recorders were operated at the
Massachusetts — New Hampshire state line, SPKTO5, and in Stevens Pond.
The data from these recorders are plotted in Figures 13 — 15.
Benthic Study
During August 8 — 9, EPA biologists conducted a qualitative
benthic macro—invertebrate study. They established control stations
upstream of the Salem Wastewater Treatment Plant (SPB1) and in Policy
Brook near its confluence with the Spicket River (PBB1). An additional
-------
8
five stations were selected in the Spicket River downstream from the
vastewater treatment plant. These stations are described in Table 2.
The organisms found at each station are listed in Table 11.
During the biological sampling, sediments were collected at three
stations (SPB4, SPB7A, and SPB7B) for in vitro sediment oxygen demand (SOD)
determinations using a bench model benthic respirometer. These data are
shown in Table 12 and were generated using the following equation:
2 ( Oi — Of) (V )
SOD gm 0 2 /m /day = At
Where: 0 2 1m 2 /day = Oxygen consumed per square meter per day
01 = Initial dissolved oxygen concentration (mg/i or gin/rn 3 )
Of = Final dissolved oxygen concentration (mg/i or gm/rn 3 )
V = Volume of confined water in cubic meters
A = Surface area of sediment in square meters
t = Time in days
-------

DISCUSSION
During the water quality study . the river flow 60 meters (200
feet) downstream from the Salem Wastewater Treatment Plant outfall
was approximately 0.54 m 3 lsec (19 cfs). This flow translates to
approximately 5.3 times the assumed one in ten year, seven day low
flow.
DO and BOD
The five—day biochemical oxygen demand in the Spicket River
is normal for New England streams which are not heavily polluted.
Upstream from the Salem Wastewater Treatment Plant organic loadings
are minimal as evidenced by the less than 1.0 mgIl BOD 5 loading at
SPKTO1. The BOD 5 load from the treatment plant increases the stream’s
BOD 5 concentration slightly. The BOD 5 concentrations in the river
were generally 2 — 3 mg/i from the treatment plant downstream
to the Merrimack River. While such an organic loading may seem
small, the physical characteristics upstream from Station SPKTO5
makes this a critical loading in the Spicket River. The quiescent
flow provides minimal aeration; thus, the BOD upsets the oxygen
balance in the stream.
At Station SPKTO3, the DO concentrations were less than 4.0
mg/i or approximately 40 percent of DO saturation, and at SPKTO4
and SPKTO5, the DO concentrations were less than 2.0 mg/i or approximately
30 percent of saturation. These concentrations are in violation
of the “B” classification which New Hampshire’s and Massachusetts’
Temperature at Station SPKTO3 assumed to be 23°C.
-------
10
water quality standards assigned to these portions of the river.
(See Tables 3 and 4.) In fact, these concentrations violate
both states t “C” classifications.
After tumbling over the dam and falls downstream from SPKTO5,
the DO concentration increased to more than 5.0 mg/l. Although
the higher DO concentration continues downstream to the Merrimack
River, Stevens Pond is the only area where the 75 percent saturation
DO water quality criterion was maintained. The increased temperature
in the pond and correspondingly lower DO saturation index
combined with a slight increase in the actual DO concentration resulted
in an increased percent saturation. However, the temperature
in the pond violated Massachusetts’ water quality standards.
Dissolved oxygen/temperature recorders showed that very
little photosynthetic oxygen production occurred at Hampshire
Roads [ approximately 60 meters (200 feet) downstream from SPKTO3].
From the Salem WWTP downstream to Hampshire Roads, the river is
well shaded by trees in the swamp. Relatively speaking, the DO
and temperatures were stable throughout the day. Based upon the
recorder data, the DO concentration was approximately 40 percent
of saturation.
Downstream at SPKTO5, photosynthesis had a more pronounced
effect. Dissolved oxygen ranged from a low of 2.5 mg/l to a high
of 5.1 mg/i. The daily fluctuation was approximately 2.0 nig/l.
The high value usually occurred at approximately 1400 hours, but
the minimum daily value would occur at 2300 hours and then begin
to increase; begin to increase at a time when photosynthesis cannot
-------
11
oCCur. Even trying to correlate the high DO’s with a low loading
from the Salem treat’nent plant (i.e. early morning flows) did
not explain the reason for DO concentrations beginning to increase
at approximately 2300 hours. Exai ’ination of the recorder charts
showed that the observation tines were correct. No satisfactory
conclusions have been dra m to explain the times when the DO
concentrations begin to increase. Also, the temperature recorder
malfunctioned at this location (see Figure 14).
In Stevens Pond, photosynthesis is rampant. The DO ranged
from 6.4 mgll to 10.3 mg/i, and the temperature remained near 23°C.
Based upon this temperature, DO saturation ranged from 73 — 117
percent. The supersaturation indicates the presence of algal blooms
which were substantiated by the algae and chlorophyl a data. The
high DO values occurred at approximately 2100 hours, later than
normally expected. The low DO concentrations were at approximately
1000 hours; again later in the morning than normally expected.
However, examination of time checks on the recorder tapes show
the times to be accurate.
Overall DO concentrations from the recorders correlate well with
values obtained during the water quality sampling program. At
Stevens Pond, the temperatures do not correlate with the temperatures
reported at SPKTO7. This is because the recorder was set up near
the center of the pond upstream from the coo].ing water discharge.
-------
12
Microbiology
The coliform data show that New Hampshire and Massachusetts
water quality criteria are violated at all stations except SPKTO5.
The analytical data indicate that sanitary waste discharges occur
upstream fron the treatment plant, in Policy Brook and especially
in the Methuen — Lawrence area.
The Salem Wastewater Treatment Plant is providing adequate
disinfection. Based upon the fecal coliform data, plant effluent
may be disinfecting a portion of the river flow. Chlorine residuals
were not measured during the study.
The total coliform data provides presumptive evidence that
an “after growth” occurs at SPKTO2. Further increases are experienced
at SPKTO3. At times high total coliform counts occur In streams
passing through swampy areas and high counts in these areas are
sometimes attributed to soils bacteria ( Enterobacter aerogenes).
Another cause of the “after growth” effect may be that the stream
was nutrient deficient and could not support additional bacteria,
but the Salem WWTP effluent may be supplying the necessary nutrients,
and the bacteria are multiplying accordingly. The fecal to total
coliform ratio indicates that direct discharges are not a problem in this
reach.
Based upon the total coliform data, SPKTO5 appears to have a toxicity
problem; however, the 80D 5 ’s and fecal coliform counts do not indicate
the same toxicity problem. This is where oil slicks were observed.
The oil slicks may contain toxicants, but no chemical analyses
were performed to verify their presence. The drop In total coliforms Is
Inexplicable.
-------
13
At SPKTO6, total and fecal coliforms increased markedly.
Thus, somewhere in the reach between SPKTO5 and SPKTO6 are one
or more pollution sources. Because the surrounding area is urban,
combined or storm sewers and runoff are probable causes. The
remaining downstream stations show similar effects. Coliforms
at SPKTO8 indicate gross pollution at that location. During the
reconnaissance and biological studies, crews observed a storm
sewer spewing wastes from the west bridge abutment and a suspected
sanitary sewer discharging near the east abutment.
Nutrients
Nutrients at SPKTO1 are negligible, but the Salem wastewater
treatment plant discharges nitrogen and phosphorus in quantities
which can create large algal blooms New Hampshire, however, has
established no water quality criteria for nutrients. The nitrogen
compounds are not well stabilized at SPKTO2 as is evidenced by
ammonia—nitrogen to nitrate plus nitrate—nitrogen concentration
ratio. In two of the three samples collected ammonia—nitrogen
concentrations were approximately four and six times the nitrite plus
nitrate—nitrogen concentrations. The ammonia—nitrogen did not
stabilize until Station SPKTO6. Figure 16 shows the average nitrogen
concentrations and ne can observe the transition occurring between
NH 3 — nitrogen and NO 2 + NO 3 — nitrogen. Thus, nitrification is exerting
an added oxygen demand upon the river. Stations SPKTO4 and SPKTO5
violate the assigned Massachusetts water quality criteria.
-------
14
Total phosphorus concentrations are relatively constant from
the treatment plant to the Merrimack River and average 0.44 mg/i.
Total phosphorus water quality criterion is exceeded at all stations
in Massachusetts.
Biology
The qualitative biological study showed the Spicket River
to be a relatively healthy stream. At SPB1, seven kinds of aquatic
benthic life were found which included mayflies and caddisflies
typical of clean, fast—flowing water. Eight kinds of organisms
were recovered from the stream bottom at PBB1, and the fauna is
typical of that found in a slow flowing ponded environment.
Stations SPB2, SPB3, and SPB4, have six, seven, and ten kinds
of organisms, respectively. The treatment plant apparently has
some adverse effect on the benthic biota as exhibited by the numbers
of kinds of organisms found (see Table 11). The effect, however,
is rapidly diminished downstream as ten kinds, including mayflies,
were found at SPB4.
Station SPB7 supported four varieties of benthic life. The
bottom sediments contained an oily residue, and the water temperature
exceeded 300 Centigrade at this location.
One kind of organism (midgefly) was recovered from Station
SPB8. This location is polluted by raw municipal waste discharges.
SUMMARY
During the water quality study, the Spicket River was organically
overloaded. Both the New Hampshire and Massachusetts established
-------
15
water quality criteria were violated. In New Hampshire, the dissolved
oxygen and coliform criteria were violated: ammonia—nitrogen and
total phosphorus concentrations were excessive. (New Hampshire
has no nutrient criteria.) In Massachusetts, dissolved oxygen,
temperature, ammonia, total phosphate, and coliform criteria were
violated.
Approximately 4.3 kilometers (2.7 miles) downstream from the
Salem, New Hampshire, WWTP’s discharge (SPKTO5) the low point in
the oxygen sag occurred. The average DO concentration from collected
samples was 2.5 mg/i. A DO — temperature recorder installed at SPKTO5
recorded diurnal fluctuations ranging from 2.5 — 5.1 mg/l.
Policy Brook which enters the Spicket River at RK 8.8 (RM 5.5)
contains evidence of fecal contamination and has BOD 5 concentrations
similar to those in the Spicket River near their confluence (SPKTO3).
In Methuen, Massachusetts, oil slicks were observed (SPKTO5, and
in Lawrence the river is heated by cooling water discharges. Bacteriological
and biological examinations evidenced that other pollution loads are
entering the river in the Methuen — Lawrence area.
