Abstract

The Environmental Protection Agency's (EPA) Contract Laboratory Program (CLP) provides a variety of state-of-the-art chemical analysis services in support of the Superfund program. The CLP utilizes inductively coupled plasma (ICP), flame atomic absorption (FAA), graphite furnace atomic absorption (GFAA), and cold vapor techniques to analyze water and soil/sediment samples for inorganic priority pollutant constituents. The data generated through the sample analyses is used by EPA to determine the existence and potential threat posed to the public and the environment by identified hazardous waste sites. The extensive quality assurance/quality control (QA/QC) system ensures that data generated by the CLP laboratories is of known quality and is legally defensible in Agency enforcement cases.
