somersworth sanitary landfill

BLACKWATER RD

The 26-acre Somersworth Sanitary Landfill is located approximately 1 mile southwest of downtown Somersworth. The City of Somersworth operated a disposal site on the property from the mid-1930s until 1981. Originally, the City burned residential, commercial, and industrial wastes at the site. In 1958, the dump was converted to a landfill. Unknown quantities of sludges, solvents, acids, dyes, metals, laboratory or pharmaceutical wastes, and potash were disposed of at the site. In 1981, four groundwater monitoring wells installed as part of site closure activities indicated that volatile organic compounds (VOCs) and inorganic contaminants were present. The landfill is located in a predominantly residential area of Somersworth. The former Forest Glade Park (currently known as St. Laurent Park), which was reclaimed as a recreational park in 1978, sits atop the easternmost 10 acres of the site. As of June 6, 2011 this park was removed from the City's Park Ordinance by vote of the City's Council. An apartment building for senior citizens, a fire station, and a National Guard Armory abut the property to the east, and an elementary school is located approximately 2,300 feet northeast. Approximately 11,000 people live in Somersworth. Most of the residences in the area obtain drinking water from the Somersworth municipal supply system; however, there are at least seven private wells in the area. Peter's Marsh Brook, located adjacent to the western edge of the landfill, is a tributary of Tate's Brook, which, in turn, is a tributary of the Salmon Falls River. Both the City of Somersworth and the City of Berwick, Maine withdraw water from the river for their drinking water supplies. Water intakes are located approximately 1 mile from the landfill.
