Abstract |
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 ensure that EPA has valid and reliable data on the conditions of these sites. Wheeling Disposal Superfund Site near Amazonia, Missouri, is one of eight sites reviewed. We collected ground water and surface water samples and compared our results to historical results reported by Region 7. We also compared results to applicable federal and state standards and conducted a site inspection. Wheeling Disposal Superfund Site operated from the 1970s through 1986. Wastes disposed at the site include leather tanning sludges, pesticides, asbestos, laboratory wastes, building debris, paint sludges, battery wastes, cyanide wastes, and miscellaneous crushed drums. The site's 20-acre central disposal area sits in the middle of the 200-acre site. Surface runoff flows to tributaries and creeks north and south of the site and eventually discharges into the Missouri River 2 miles south of the site. |
