The 13-acre Winthrop Landfill site is located in Winthrop, Maine. The area is located west of Lake Annabessacook and consists of two adjacent properties, the Winthrop Town Landfill and the privately owned Savage Landfill. A sand and gravel pit initially operated on site in the 1920s. In the 1930s, parts of the site received municipal, commercial and industrial wastes. The site accepted hazardous substances between the early 1950s and mid-1970s. It is estimated that more than 3 million gallons of chemical wastes, mostly complex organic compounds including resins, plasticizers, solvents, and other process chemicals, were disposed of at the site. Following construction of the site’s long-term remedy, operation and maintenance activities and monitoring are ongoing.
