Laboratory Certifications
The Laboratory Certification Program operates under the authorization of the Michigan Safe Drinking Water Act, 1976 PA 399, as amended (Act 399), and the United States Environmental Protection Agency (USEPA) to certify laboratories for the analysis of drinking water. All laboratories testing Michigan drinking water samples for regulatory and compliance monitoring must be certified by this program.
The Laboratory Certification Program certifies laboratories to ensure that proper methods and quality control are used in the testing of drinking water samples. The certification process includes an extensive review of the applicant laboratory Quality Assurance Program Plan, Standard Operating Procedures, as well as an on-site audit of the facility and analytical data. Areas of certification include Bacteriology, Wet Chemistry, Organic Chemistry, and Inorganic Chemistry.
