Frequent Questions

What are the requirements for becoming certified as an operator of a public water system (PWS)? Does EPA have some sort of test procedure?

EPA does not provide PWS operator certification. Pursuant to the Safe Drinking Water Act Amendments of 1996, EPA developed and issued guidelines specifying minimum standards for certification and recertification of the operators of community and non-transient, non-community PWSs. States are required to implement these guidelines or an equivalent state program. In addition, EPA will reimburse the training and certification costs for operators of smaller systems (those serving less than 3,300 persons) by providing grants to states.
