摘要

The 1-acre Action Anodizing, Plating, and Polishing (AAPP) site is an active metal finishing shop located in Babylon, Suffolk County, New York. Land use in the area is primarily residential and commercial. An estimated 1 million residents use public wells within 3 miles of the site for their drinking water supply. From 1938 to 1968, a commercial laundry facility operated onsite; subsequently, AAPP has operated at the site as a small metalfinishing plant. Site features include the AAPP operating facility, an adjacent storage area, and a residence. Onsite operations involve sulfuric acid anodizing of aluminum parts for the electronics industry, cadmium plating, chromate conversion coatings, metal dyeing, and vapor degreasing. Liquid wastes from these operations include rinses of spent caustic and acidic solutions contaminated with cadmium, chromium, zinc, and sodium cyanide. Prior to 1980, these spent solutions and rinses flowed from a concrete waste-holding trough to a septic tank and several leaching pits for tank overflow. In 1980, the county identified elevated levels of cadmium, chromium, and nickel in the onsite leaching pits. That same year at the direction of the county, AAPP removed the contaminated substances from the leaching pits, backfilled, and closed the pits. This ROD addresses OU1, which includes the whole site. Samples of ground water, soil, and sediment taken from onsite and offsite areas during the RI showed that contaminant levels were generally well below state and federal standards and risk levels. Therefore, the AAPP site does not pose an unacceptable risk to human health or the environment.
