Re: Subsurface Disposal Services
IvCs. Starr,
Attached are copies of field notes for your files for tests performed on 160 Boston Road
and 106 Gray Road, as well as 1620 Turnpike Street. A short synopsis is as follows:
4/$/03 J
On site where Al Gala, Engineer,.__ ..
owner Charles Hat and the backhop,operator, This is a
r it to an existing system, percolation rates were 9 rain./inch and 12 min./inch. Water
Cables(Estimated seasonal high)were at 39”and 40"', fairly consistent over the site. This
is an ice contact ablation till, lots of stones in a loamy sand soil. Where was s wet area to
the rear of the lot near the Bence that had a likely predominance of wet veptation and
soils consistent with a potential wetland.I alerted the engifter to this and he informed me
he would have a wetland scientist view the area. No ledge or other site difficulties were
evident. There is a potential intermittent stream off site on adjacent lots,,though the
distance from this property do not seem to make it a problem.
160 Boston Road
`!/17/03
On site were Jim Garoulis,Engineer and Kim Hadeverian, owner, and the backhoe
operator,This was also a repair. Jim had five deep tests open,three to the&W right of
the lot and two to the rear. Water tables to the front were at 36", 30",and 30".To the rear
they were at 48"and 52". This is a basal till soil consisting of fine sandy loank compact
in plane, massive but friable. One percolation test(pert 2)performedl at 56"was started,
but was going at greater than ten minutes per inch. I believe this test was into the seasonal
high groundwater, or at least in the capillary layer resulting in the slower rate. A second
best was performed slightly higher with a final rate of 18 minutes per inch. I believe this
rate is representative of the soil. There are no wetlands, ledge, or other apparent
difficulties on the lot.
