Town officials have agreed to amend a consent decree with the U.S. Environmental Protection Agency regarding the town’s superfund landfill and arsenic accumulating in the sediment at Hoyt Brook. The Winthrop landfill, which consists of two contiguous parcels of 11 acres, 9.5 of which are along the shore of Annabessacook Lake, was deemed a superfund site in 1985. According to the Nov. 22, 1985, decision, “it is estimated that more than three million gallons of chemical wastes, mostly complex organic compounds including resins, plasticizers, solvents, and other process chemicals were disposed at the site.”
