The Office of Inspector General (OIG) of the U.S. Environmental Protection Agency (EPA) is evaluating long-term monitoring at Superfund sites deleted from the National Priorities List (NPL). This evaluation is to determine whether EPA has valid and reliable data on the conditions of these sites. PAB Oil and Chemical Services, Inc., Superfund Site, in Abbeville, Louisiana, is one of eight sites being reviewed. At PAB, we collected ground water samples and conducted a site inspection. We compared our results to past results reported by EPA Region 6.
