The Re-Solve, Inc. site is a former waste chemical reclamation facility situated on six-acres of land in North Dartmouth, Massachusetts. Bounded by wetlands to the north and east, the land surrounding the site is predominantly zoned for single family residential use. All residences obtain their water from private wells located on their property. The Copicut River, located about 500 feet from the site, has been designated for protection. Between 1956 and 1980, Re-Solve, Inc. handled a variety of hazardous materials including solvents, waste oils, organic liquids and solids, acids, alkalies, inorganic liquids and solids and PCBS. Residues from the distillation tower, liquid sludge waste, impure solvents and burnt tires were disposed of in four onsite unlined lagoons. An oil waste that accumulated at the bottom of the degreaser distillation still was disposed of on one portion of the site through landfarming. In 1974 the Massachusetts Division of Water Pollution Control issued Re-Solve, Inc. a license to collect and dispose of hazardous waste. In December 1980 the Massachusetts Division of Hazardous Waste agreed to accept Re-Solve's offer to surrender its disposal license.
