Drinking Water Laboratory Certification

The Remediation and Redevelopment Division (RRD), within the Michigan Department of Environment, Great Lakes, and Energy (EGLE), has the responsibility for the certification of drinking water testing laboratories under the authority of Public Act 399 of 1976, as amended. These laboratories must be certified for the protection of public health.


Certification for Drinking Water Testing Laboratories

 1.  Applicability (activities that require the permit)

All laboratories used for testing of potable water as required for compliance and monitoring purposes.

 2.  Pre-Application Requirements
  • Laboratories must have sufficient space, required instruments/equipment, trained technicians, use of approved methodology, and maintain appropriate records.
  • Laboratories must successfully analyze proficiency test samples (when available) on a running 12-month basis from an approved proficiency test provider.
3.  Application Submission Requirements

Laboratories must have a true and updated address, an identified contact person officially representing the laboratory, results of the analysis of performance evaluation samples, parameters where certification sought, copy of the Quality Assurance Plan, and a full payment for the appropriate certification fee.

 4.  Procedures and Time-Frame for Obtaining Permit or Approval

An application is submitted to the RRD, Laboratory Certification Program. Laboratories must apply for recertification at the end of each three-year certification period. Recertification applications will be mailed by the program officer.

5.  Operational Requirements
  • Laboratories must pass physical inspection and meet the requirements set forth in the Manual for the Certification of Laboratories Analyzing Drinking Water: Criteria and Procedures Quality Assurance Manual, 4th Edition, March 1997, U.S. Environmental Protection Agency (U.S. EPA), and the requirements periodically published in the Federal Register.
  • Laboratories are evaluated at least once every three years by an evaluating officer assigned by RRD and approved by the U.S. EPA. Laboratories may be evaluated any time within the standard three-year certification period for continued compliance with the standards. These inspections may be announced or unannounced.
 6.  Fees

Fees adjusted annually based on Consumer Price Index.

 7.  Appeal Process
  • The person in charge of a laboratory may informally appeal questionable areas with laboratory certification office.
  • Formal appeal from a laboratory may be made in accordance with the Administrative Procedures Act.
 8.  Public Input Opportunities

This is a science-based certification program to assure that drinking water laboratories are performing at a level consistent with protecting public health. Complaints related to a facility may be filed with the EGLE at any time. The complaints are investigated and considered in the decision-making process when the facility applies for renewal. The Laboratory Certification Officer will make a determination through consultation with the Chief of Laboratory Services. These facilities are inspected for deficiencies which must be addressed before their certification.
