Quality Assurance Support for the Superfund Contract Laboratory Program
SourceThe Environmental Protection Agency's Environmental Monitoring Systems Laboratory-Las Vegas (EMSL-LV) functions as the quality assurance (QA) arm of the Contract Laboratory Program (CLP). The EMSL-LV provides standards and quality assurance materials, maintains a quality assurance data base, and conducts data audits, performance evaluation studies, and on-site laboratory evaluations. In addition, the EMSL-LV is very actively involved in evaluating laboratory and method performance. Due to its unique position of receiving all of the data from all of the CLP laboratories, combined with its charge of quality assurance oversight, EMSL-LV is most able to assess intra- and inter-laboratory performance as well as programwide method performance. This paper describes the EMSL-LV QA program for the CLP as of October 1985.
