The 850-acre Groveland Wells site is located in the Town of Groveland, Essex County, Massachusetts within the lower Johnson Creek drainage basin. The site includes the watershed and aquifer which recharge two municipal supply wells, Station Nos. 1 and 2, and three known sources of soil, surface water, and ground water contamination: the Valley site, the A.W. Chesterson site, and the Havenhill Municipal Landfill site. The selected remedial action for the Valley site operable unit includes: in situ vacuum extraction of approximately 20,000 cu yds of unsaturated soil followed by activated carbon treatment of the extracted VOCs; onsite ground water pump and treatment by carbon adsorption and aeration, with recharge to the aquifer of a portion of the treated ground water.
