Laboratory Certification Information & FAQ

Ohio EPA certifies laboratories that test environmental samples which support voluntary cleanups. Before any certification is issued, Ohio EPA will conduct an evaluation of the laboratory’s documents and staff in order to determine its qualifications for certification. This evaluation includes a detailed technical review of all laboratory documents associated with an application and an on-site inspection to assess analysts skills and knowledge in conducting the analyses.
