The Spence Farm site is located in Plumsted Township, New Jersey. From the 1950s to the 1970s, hazardous wastes were disposed of across 20 wooded, low-lying acres of the 87-acre site. Dumping contaminated groundwater and surface water with volatile organic compounds (VOCs). VOCs are potentially harmful contaminants that can easily evaporate into the air. The site is one of four Superfund sites, including Pijak, Hopkins and Goose Farms, within a two-mile radius. Following immediate actions to protect human health and the environment, the site�s long-term remedy was put in place. After cleanup, EPA took the site off the Superfund program�s National Priorities List in March 1997.
