EPA Adds New Hazardous Waste Sites to the NPL
On September 23, 2004, EPA added two hazardous waste sites to the Superfund National Priorities List (NPL): Ravenswood PCE Ground Water Plume (Ravenswood, WV) and White Swan Cleaners/Sun Cleaners Area Ground Water Contamination (Wall Township, NJ). EPA also proposed the addition of 14 other sites.
EPA selected these sites based on various factors, including risk to human health and the environment; the urgency of the need for response; projected total costs to the Fund; maintenance of a strong enforcement program; leverage of cleanups by others; and the level of support for listing from the States and communities.
Detailed information on the proposed NPL listing, including the Federal Register notice announcing the listing, supporting documents and instructions for submitting public comments, may be found at:

EPA is adding the Ravenswood site because tests of three of the city's five municipal drinking water wells showed tetrachloroethylene (PCE) contamination up to 91.4 parts per billion (ppb). (As an interim solution, the city pumps the contaminated water to a treatment plant, cleans it, then blends it with water from uncontaminated sources. In addition, EPA installed two new wells in areas unaffected by the contamination.) The Ravenswood blended water supply system provides drinking water to over 7,800 people and five schools.
The addition of the White Swan Cleaners/Sun Cleaners site is necessary because of actual and potential contamination of municipal drinking water wells. The site consists of a broad area of PCE contamination from at least two dry cleaning establishments. PCE was detected in one municipal well at a concentration of 0.54 ppb, in irrigation wells as high as 1,546 ppb, and in monitoring wells near the dry cleaners at concentrations as high as 200,000 ppb.
The 14 proposed sites present an array of contaminants, including lead, arsenic, cadmium, perchloroethylene, trichloroethene, pesticides, polycyclic aromatic hydrocarbons (PAHs), polychlorniated biphenyls (PCBs), radionuclides, volatile organic compounds (VOCs), and semivolatile organic compounds (SVOCs). The sites are:
- Klau/Buena Vista Mine, San Luis Obispo County, CA;
- Hegeler Zinc, Danville, IL;
- Sigmon's Septic Tank Service, Statesville, NC;
- Parkview Well, Grand Island, NE;

- Copley Square Plaza, Copley, OH;
- South Dayton Dump & Landfill, Moraine, OH;
- Price Battery, Hamburg, PA;
- Safety Light Corporation, Bloomsburg, PA;
- Pesticide Warehouse I, Arecibo, PR;
- Brewer Gold Mine, Jefferson, SC;
