claremont polychemical

501 WINDING ROAD

The Claremont Polychemical Site, situated on an approximately 9.5-acre site, is a former manufacturer of pigments for plastics and inks that operated from 1966 to 1980. During its operation, Claremont Polychemical Corporation (Claremont) disposed of liquid wastes in three leaching basins and deposited solid wastes and treatment sludges in drums or in old, aboveground metal tanks. During a series of inspections in 1979, the Nassau County Department of Health (NCDOH) found 2,000 to 3,000 drums containing inks, resins, and organic solvents throughout the site. Some of the drums were uncovered, while others reportedly were leaking. NCDOH inspectors noted that an area east of the building was contaminated with organic solvents that resulted from spills and discharges. Claremont sorted and removed the drums from the site in 1980. A subsequent investigation by NCDOH revealed most of the drums were gone, but an area of soil (referred to as the "spill area") was visibly contaminated with inks and solvents. As a result, Claremont was directed to install groundwater monitoring wells. The closest residences are located approximately 1/2 mile from the site. Approximately 47,000 people draw drinking water from wells located within 3 miles of the site. The nearest public water supply well is 3,500 feet northwest of the site.
