The Claremont Polychemical Superfund Site, located in a light industrial area of Old Bethpage, Nassau County, New York, is approximately 10 acres in area. The site addresses contamination stemming from the operations of a former manufacturer of pigments for plastics, inks, coated metallic tanks, and vinyl stabilizers. Leaking drums of hazardous chemicals, primarily volatile organic compounds (VOCs) were discovered by the Nassau County Health Department (NCHD) in 1979, and soil and groundwater
contamination beneath the site were discovered in 1980. A series of remedial actions by the property owners began later that year, but subsequent investigations revealed additional contamination. The site was placed on the National Priorities list in June 1986.
