The Site, located in a rural, residential area at 91 Western Avenue, Henniker, New Hampshire (Long. N71° 50' 34", W Lat. 43° 10' 09"), consists of the former disposal location of sludge and solid waste for the Contoocook Valley Paper Company (CVPC). The parcel of concern is across the street from the former location of the CVPC facility where the Environmental Protection Agency (EPA) conducted a removal action in 1992 and 1993.
This inactive two acre parcel is generally flat with some mounds and depressions created during previous test-pitting activities. The Site is bordered by moderate to steep banks leading down to the river and sluiceway. The area is covered by young pine trees and mixed vegetation throughout with older hardwood trees along the north and south edges of the property.
The Site is bounded by:
• North - Sluiceway;
• South - Residential property;
• East - Contoocook River; and
• West - Western Avenue.
From 1999 through 2002, New Hampshire Department of Environmental Services (NH DES) conducted a Brownfields assessment to characterize the environmental conditions on both parcels and referred the eastern parcel for further investigation. On May 6-9, 2003, and June 3, 2003, the EPA OSC and EPA contractors, together with NH DES staff, conducted a Removal Program Preliminary Assessment/Site Investigation (PA/SI).
The key finding of the PA/SI was heavy metal contamination of surface and subsurface soils due to burial of sludge waste and on-site placement of bulk paper products. The primary metals of concern and their maximum concentrations are shown in the table below:
Substances Media Maximum
Lead soil 7,979ppm
Cadmium soil 1,340ppm
Barium soil 24,480ppm
Chromium soil 1,622ppm
