Frequent Questions

States are required to make the results of source water assessments available to the public (SDWA 1453(a)(7)). How does EPA define "public?" Does EPA provide guidance on recommended methods states may use to make these assessments available to the public?

Public is defined as all consumers in a source water protection area as well as all other members of the public, including federal, state, and local government agencies. Public water systems must include information on the availability of completed source water assessments in their annual consumer confidence reports (141.153(b)(2)). Additional methods for making assessment results available to the public can be found in the State Source Water Assessment and Protection Programs Final Guidance (EPA816-R-97-009, August 1997) available at
