Reference Samples for Water-Related Programs in the U.S. Environmental Protection Agency


The Environmental Monitoring and Support Laboratory at Cincinnati provides quality assurance (QA) support for U.S. Environmental Protection Agency (EPA) water-related programs in response to the Clean Water Act (P.L. 92-500), the Safe Drinking Water Act (P.L. 93-523), the Marine Protection, Research, and Sanctuaries Act (P.L. 92-532), the Resources Conservation and Recovery Act (P.L. 94-580), the Comprehensive Environmental Response and Liability Act (P.L. 96-510), and the Toxic Substance Control Act (P.L. 94-469), and their amendments.

Two important segments of this support are the Quality Control Sample Program, which furnishes samples of known concentrations for use as independent checks on intralaboratory QA activities, and the EPA's Repository for Toxic and Hazardous Materials, which provides calibration standards and spiking solutions for trace organic analyses of interest to the Agency. Each series contains one or more analytes, with true or reference values. The samples and standards are prepared as stable concentrated solutions in all-glass ampuls for dilution to volume, and analyses by EPA, its contractors and grantees, and other federal, state, and local agencies.
