Gentlemen:
I have made a percolation test on land to be purchased by
the Sun Oil Company, located on the Westerly side of the Mount
Tom Highway just South of the Atwood Airport hangar building.
This test was done on the level farmland area to the West of the
Highway.
Type of Soil:
0" — 9" silty loam
9" — 48" very fine sand and silt; some
clay
Percolation Rate: 1" = 8 minutes
No ground water or ledge was encountered at this site.
Please note that at this site, if the permit is granted, a modern
filling station will be built. However, the filling station will
be built on approximately 6' to 8' of fill above the existing
ground level. This will enable the station to be erected level
with the proposed new Highway running South to Mount Tom Junction.
At the time the new station is constructed, the area in which the
septic tank and leaching facilities would be constructed should be
of coarse bank run gravel.
If you have any questions regarding this site, please do not
hesitate to contact me.
Very truly yours,
es

channel. The open channel stream is referred to locally as Borowski Brook and runs for
approximately 4,000 feet adjacent to Mountain Street before discharging to the Mountain Street
Reservoir.
Mountain Street Reservoir is supplied by discharge from the West Whately reservoir and storm
water runoff from the adjacent hillsides along Mountain Street. A portion of the adjacent
drainage area to the north of the reservoir is diverted around the reservoir by a system of dykes
and a swamp drain. The swamp drain discharges south of the Mountain Street Reservoir dam
through a pipe along the bottom of the reservoir. Discharge over the Mountain Street Reservoir
spillway enters Beaver Brook and eventually flows to the Mill River in Northampton. Currently
only about 10% of Northampton's supply comes from the Mountain Street Reservoir as water
from this source cannot feed the WTP by gravity and must be pumped.
The treatment processes at the WTP include chemical addition, mixing, clarification, filtration,
pH adjustment, and disinfection. After the raw water from one of the sources referenced above
enters the WTP, liquid aluminum sulfate (alum) and a coagulant aid polymer(Kemira®
Superfloc C-572 Cationic ployamine) are added to enhance coagulation and flocculation in the
adsorption clarifiers. The chemically treated water is then mixed by a static mixer (flocculated).
Once the water has passed the static mixer, it is equally divided between the adsorption
clarifiers. The WTP uses a high rate up-flow clarification process that separates solids from the
water by attachment of the flocculated solids onto the surface of a buoyant media that is
installed in the clarifier. The solids collected on the media are removed by a backwash cycle
which introduces air into the tank to expand and agitate the media bed. The solids released
from the media are flushed away with incoming raw water and transferred to the equalization
tank and two lagoons for settling. Overflow from these lagoons is then discharged to the
Mountain Street Reservoir.
From the adsorption clarifiers, water flows by gravity to the filter header which supplies water to
activated carbon filters. The media in the filters must be backwashed periodically to remove
collected solids. Backwashing forces water to flow in the reverse direction, up through the filter
underdrain and media, to dislodge the solids collected in the media. The spent wash water
generated from a backwash cycle is collected in the filter wash water troughs, and then flows
into the filter gullet and into a spent wash water pipe leading to the equalization tank prior to the
lagoons. Filtered water flows by gravity through the air break box, then through the flow meter
chamber, and finally into the clearwell. Sodium hypochlorite is added to the filtered water
downstream of the air break box for disinfection. Treated drinking water flows by gravity from
the clear well to the transmission mains which deliver potable water to the City's distribution
system.
Residuals Lagoon System:
As noted above, process wastes from filter and clarifier backwashing are discharged to one of
two onsite lagoons for dewatering. The lagoons operate on an alternating annual cycle where
the active lagoon receives all the WTP waste flow, while the inactive lagoon goes through a
freeze/thaw air drying and dewatering cycle.
Residuals concentrated in the inactive lagoon are then removed on an annual basis or when the
residual layer reaches an average depth of three feet. Table 1 summarizes chemicals used in
the water treatment process at the Northampton WTP:

Sampling and Analysis Plan Approval
MassDEP Project 214-002
PWS ID 1214000
Transmittal X267686
The Department of Environmental Protection (MassDEP or the Department) is in receipt of an
application from the City of Northampton, submitted in accordance with 310 CMR 32.00,
"Regulations for the Land Application of Sludge and Septage". The application contains
documentation to support a BRP WP 28 Permit "Sampling and Analysis Plan Approval for
Approval of Sampling and Analysis Plan"(SAP).
Project Background:
Northampton' eceives and treats raw water
from the Ryan, West Whately and Mountain Street Reservoirs. The Mountain Street WTP
provides potable drinking water to the City of Northampton's distribution system.
The Ryan Reservoir is constructed on Avery Brook, north of and adjacent to the West Whately
Reservoir. Ryan reservoir was originally designed and operated to provide additional storage
for the West Whately and Mountain Street reservoirs but in the mid-1990's the water mains
were reconfigured to allow Ryan Reservoir operate as an independent water source. Ryan
Reservoir is currently the primary source of water for the WTP. Ryan Reservoir is supplied by
Avery Brook and other unnamed streams and tributaries.
The West Whately Reservoir operates as a diversion dam on West Brook with overflow from the
source to the Mountain Street Reservoir. West Whatley Reservoir is supplied primarily by an
upper tributary of West Brook. Source water originating from the West Whately Reservoir, flows
cross-country through a 20-inch diameter cast iron transmission line that discharges to an open

Plan Summary
This SAP approval application indicates that Northampton has a Beneficial Use Determination
(BWP SW40 BUD; since expired and not currently renewed)to utilize the residuals from the
WTP as alternate daily cover at its solid waste landfill. Since this landfill is no longer available
to the City, and alum based sludge may be land applied for fill material, Northampton proposes
to use the residuals in various public works projects that are currently undefined.
All Type 1 approvals require an Acceptable Process for Pathogen Reduction (PFPR). In order
to comply with this requirement, Northampton proposes to utilize the Air/Freeze Drying method
in its lagoons as a PFPR.
