| Abstract |
The 9.5-acre Claremont Polychemical site is an abandoned production facility in Oyster Bay, Nassau County, New York. The principal wastes generated were organic solvents, resins, and mineral spirits wash wastes. In 1979, the State identified improper storage practices onsite, including stockpiles of over 2,000 uncovered or leaking drums of wastes and an onsite spill area. Organic solvents from several onsite spills and discharge incidents may have contaminated onsite soil and ground water. By 1980, most of the onsite drums were sorted and removed offsite, reused, or burned onsite. Subsequently, contaminated soil was excavated and placed on a plastic sterile liner, which has degraded over time. Ground water investigations in 1980 revealed ground water contamination directly under the site. The remedial actions for the site have been divided into two Operable Units (OUs). The Record of Decision (ROD) focuses on OU2, overall remediation of ground water and soil/wastes contained onsite in drums and holding basins. The primary contaminants of concern affecting the soil, debris, and ground water are VOCs including PCE, TCE, toluene, and xylenes; other organics; metals including arsenic, chromium, and lead; and inorganics including asbestos. |
