Remediation System Evaluation, Groveland Wells Superfund Site

The Groveland Wells Superfund site is located in Groveland, Essex County, Massachusetts and has soil and ground water contaminated with trichloroethylene (TCE) and its degradation products. Soil and ground water impacts result from operations and disposal practices associated with screw machine manufacturing at the Valley Manufactured Products facility, which is located at the southern part of the site. An estimated volume of 3,000 gallons of TCE was released into the subsurface. Persistent and elevated concentrations of TCE (as high as 150,000 ug/L) on the Valley Manufactured Products property indicate the presence of a continuing source of ground water contamination.
