Dear Marcel:
Re: Hatheway and Patterson
Site Number 4-0571
On July 26, 1990, Keystone Environmental Resources, Inc., on behalf of Hatheway
and Patterson Company, Inc., submitted the 'Preliminary Design Report for the
Short Term Measure:' Due to the absence of groundwater contours in the
immediate vicinity of the river bank where a floating material periodically (typically
after heavy rainfall events) discharges to the Rumford River, Hatheway and
Patterson has agreed to a limited field investigation. The purpose of this
investigation is to identify the extent of affected soils along the river bank and to
complete the groundwater contours to the river's edge. The results of the
assessment will facilitate the finalization of the design of the Short Term Measure
barrier and collection system.
As requested in MA DEP" s 7/5/90 correspondence, Keystone is presently arranging
to have a soil sample collected from the visibly stained area along the bank of the
Rumford River. Details pertaining to the sampling and analytical work are outlined
in Keystone's 8/15/90 correspondence.
Keystone proposes to perform six soil borings along the Rumford River where
seepage has been observed. These borings will be spaced on approximately twenty
foot centers from the center of the seepage in both upstream and downstream
directions. These borings will be drilled to a maximum depth of feet below the
groundwater surface or to below any stained soil, whichever is deepest. Soil samples
will be collected continuously with split spoon samplers to determine the extent of
potential horizontal and vertical contamination. Soil samples will be field classified
according to the Unified Soil Classification system. Evidence of visible and odoKous
contamination will be noted on the lithologic logs. A photoionization device, the
