Samples taken from drums, tanks and other containers, and other samples suspected of having high concentrations of hazardous waste from 221 disposal sites in 41 states and one territory have been prepared for analysis by the Regulated Substances Laboratory (RSL), located at the Environmental Protection Agency's (EPA) National Enforcement Investigations Center (NEIC), and operated under contract to the EPA Contract Laboratory Program (CLP) by Fred C. Hart Associates, Inc. These samples were taken from a wide spectrum of hazardous waste sites by EPA and State personnel and contractors retained by EPA for the conduct of hazardous waste site evalutations. After preparation in the RSL, these samples were analyzed in environmental laboratories of the EPA Regions, the NEIC and in eight CLP laboratories. The data generated by these analyses are believed to represent, generally, a measure of the chemical content of drums and other waste containers on hazardous waste sites throughout the nation, and provide policy-makers, industry and regulatory agency managers, investigators, and analysts with a basis for greater confidence in decisions regarding exposure risks to the public and to personnel engaged in hazardous waste site evaluations. |
