groveland wells


The Groveland Wells Superfund site includes the watershed and aquifer supplying two municipal water wells, as well as three properties known to be polluting groundwater and soil in the area. The entire site area covers a total of approximately 850 acres. Groveland production wells #1 and #2 were the sole source of drinking water for the town. Both were shut down in 1979 when the State detected Trichloroethylene (TCE) contamination above drinking water maximum contaminant limits (MCLs). The town instituted emergency conservation measures and temporarily obtained water hookups from neighboring communities. Groveland developed well #3 along the Merrimack River in the early 1980's, however the water supply fell short of the town's needs and growth trends. The main source of contamination was determined to be from the former Valley Manufacturing Products Company (VMPC) site located on Washington Street in Groveland, where metal parts, screws and cable connectors had been made since 1963. Operators used subsurface disposal systems which dispersed liquids into buried leachfields and also had a major leak from an underground storage tank (UST) containing Trichloroethylene (TCE). VMPC also routinely dumped hazardous materials on the surface of the ground which eventually leached down to the groundwater. Hazardous substances that were released included cutting oils, mineral spirits, TCE , volatile organic compounds (VOCs), and acid bath wastes. In 2000, EPA funded and built a groundwater extraction, treatment and discharge system to clean up the TCE contaminated groundwater in the aquifer near the former Valley Manufacturing building. From April of 2009 thru February of 2011, EPA funded, constructed and operated the ERH thermal treatment system in the Source Area. According to the 2010 U.S. Census, approximately 6,459 people live within the town of Groveland.
