The 8-acre Diamond Shamrock Corp. Landfill site is located in Cedartown, Georgia. The site includes an area used to dispose of waste oil and other waste products from chemical manufacturing operations in the late 1960s or 1970s. EPA placed the site on the Superfund program�s National Priorities List (NPL) in 1990 because of contaminated groundwater resulting from the disposal area waste. EPA, the Georgia Environmental Protection Division (Georgia EPD) and the site�s potentially responsible party (PRP) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site. Residents and businesses use the public water system for drinking water. By monitoring groundwater and undertaking Five-Year Reviews, EPA, Georgia EPD and the site�s PRP continue to protect people and the environment from site contamination.
