The Oklahoma Department of Environmental Quality operates the laboratory accreditation program to insure the quality of analytical data received by the DEQ Water Quality Division and other state agencies for compliance and decision making purposes. Our goal is to provide standards for accreditation of privately and publicly owned laboratories for performance of analyses of water, wastewater and sludge.
Laboratories are accredited to do general water quality, sludge testing, and drinking water analyses. A laboratory may not be accredited to perform all the possible parameters offered for accreditation. To verify that a laboratory is currently accredited for a particular parameter, please contact
