Safe drinking water is essential.

NSF International Strategic Registrations (NSF-ISR) serves as one of only two approved accreditation bodies for the Ontario Ministry of the Environment Drinking Water Quality Management Standard (DWQMS).

The Ontario Safe Drinking Water Act, 2002 requires an accredited operating authority to be in charge of a municipal residential drinking water system. This authority must establish and maintain a quality management system that meets the requirements of Ontario Ministry of the Environment DWQMS.

NSF-ISR provides the required third-party verification that, for a specific drinking water system, an operating authority has a quality management system in place that meets the requirements of the standard.

Accreditation Process

The process of earning accreditation to the Ontario Ministry of the Environment DWQMS includes these steps:

  1. Your company fills out a DWQMS quote questionnaire and transfer acknowledgement form for the Ministry of Environment, and signs a contract (master agreement).
  2. NSF-ISR assigns an auditor team.
  3. We perform an off-site Systems audit (when required) for the drinking water quality management system (DWQMS) and prepare a report of conformance or nonconformance.
  4. Our audit team conducts an on-site audit to verify conformity to the specified standard.
  5. A certification board reviewer recommends the final DWQMS accreditation/DWQMS reaccreditation decision.
  6. Once you receive accreditation, we advise you in writing, issue the certificate and publish the DWQMS accreditation on our website.
  7. We perform annual audits to verify the DWQMS is being maintained.
  8. We perform on-site verification audits in accordance with requirements for reaccreditation.
