The Site is located in Troy, Cheshire County, New Hampshire, along an unpaved, gravel access road originating from Rockwood Pond Road in Fitzwilliam, Cheshire County, New Hampshire. The Site is an approximately 10-acre inactive landfill. It consists of an estimated 2-acre area where approximately 6,000 to 10,000 55-gallon drums are buried and an estimated 8-acre inactive solid waste landfill. Historical information shows that from 1967 until 1978, Troy Mills, Inc., used the 2-acre area as a landfill for the disposal of solid and liquid wastes generated at its off-site facility located in the Town of Troy, New Hampshire. Drummed wastes consisted primarily of plasticizers including bis(2-ethylhexyl)phthalate (DEHP); and Varsol, a petroleum-based solvent, also known as mineral spirits or Stoddard Solvent.
An estimated 3,886 people reside within 4 radial miles of the Site. Approximately, 3,111 are served by public or private drinking water supply wells. The nearest private drinking water supply well is presumed to be located within 0.5 radial miles of the Site. The nearest public drinking water supply well is located 2.8 miles southeast of the Site. Sensitive environments located within 4 radial miles include 2,173 acres of wetlands, a CWA-protected water body, and habitats for eight State-listed endangered or threatened species.
A September 2002, EPA conducted a Preliminary Assessment and Site Investigation Report (PA/SI) consisting of a geophysical survey, test pit excavation and sample collection activities, which confirmed historical information that the 2-acre area of the Site contains approximately 6,000 to 10,000 55-gallon buried drums. Drums excavated during the pit excavation activities were analyzed for content. Analytical results of the drum contents reveal liquids/sludges, consisting of flammable substances, volatile and semivolatile organic compounds (VOCs and SVOCs) as well as inorganic contaminants. Analytical results of surficial and subsurface soil samples, as well as surface water samples collected immediately down gradient from the drum burial areas, confirm visual observations that the buried drums are releasing the above mentioned substances.
Based on the conditions of the Site, EPA in a September 23, 2002, Closure Memorandum, determined that a time critical removal action under section 300.415 of the National Contingency Plan (NCP) was necessary and appropriate. The removal action activities were initiated on May 19, 2004 and will include the removal and disposal of drums and the surrounding contaminated soils.
