Shpack Landfill is a hazardous waste site in Norton, Massachusetts. After assessment by the United States Environmental Protection Agency (EPA) it was added to the National Priorities List in October 1986 for long-term remedial action. The site cleanup is directed by the federal Superfund program. The Superfund site covers 9.4 acres, mostly within Norton, with 3.4 acres in the adjoining city of Attleboro. The Norton site was operated as a landfill dump accepting domestic and industrial wastes, including low-levelradioactive waste, between 1946 and 1965. The source of most of the radioactive waste, consisting of uranium and radium, was Metals and Controls Inc. which made enriched uranium fuelelements for the U.S. Navy under contract with the U.S. Atomic Energy Commission.
