Superfund Site: NORTH SEA MUNICIPAL LANDFILL
NORTH SEA, NY
Superfund Site Profile
The North Sea Municipal Landfill is located in Southampton, New York. The 131-acre North Sea Landfill Superfund site is an inactive municipal landfill owned and operated by the Town of Southampton, New York. The landfill accepted trash, construction debris and septic system waste from 1963 to 1995. The site consists of four areas: Cell No. 1, Cell No. 2, Cell No. 3 and former septic sludge or scavenger lagoons. Site monitoring found that disposal activities resulted in the contamination of groundwater, surface water and soil with heavy metals. Monitoring also found evidence of leachate from the landfill. In 1986, EPA placed the site on the Superfund program’s National Priorities List (NPL). Cleanup activities included closure of Cell No. 1 by constructing a landfill cap and perimeter gas venting system. EPA determined that groundwater required no action because contaminant levels were within EPA's acceptable risk range. All cells are now permanently closed and Cells No. 2 and No. 3 are no longer part of the site. The New York State Department of Environmental Conservation regulates those cells under its municipal waste landfill closure program. EPA deleted the site from the NPL in 2005.
