Drinking Water Operator Certification

Welcome to the National Environmental Services Center's (NESC) Drinking Water Operator Certification Web page. The NESC recognizes the significance of operator training and education because the health of a community relies on having competent drinking water treatment operators. This site provides resources about drinking water operator certification.

Drinking water operator certification not only establishes minimal professional standards, it also gives drinking water operators the knowledge and understanding they need to provide safe, adequate drinking water supplies to their customers. In turn, system customers can have confidence in the drinking water treatment system, because they know that the person responsible for supplying drinking water is a skilled professional.

Drinking water operator certification requirements vary from state to state. Make sure you check with the primacy agency in your state to get accurate information about the requirements you will need to be familiar with.

State-by-State Information
Drinking water operator certification is managed on a state-by-state basis and each state has somewhat different rules. The Association of State Drinking Water Administrators (ASDWA) provides links to each state's primacy agency for specific information about your state's requirements. Access this information on the ASDWA Links page.

Use the U.S. Environmental Protection Agency's (EPA) Web site to find your state's primacy agency on their Local Operator Certification Information interactive map. This Web site offers many other resources. Information can be found in their Ground Water & Drinking Water section called Operator Certification.

The NESC houses many of the resources that operators need to be prepared for certification exams, including:
