EPA has published an updated version of the State Emergency Drinking Water Supply (EDWS) guidance, which can be used by state drinking water primacy agencies as a starting point in the development of a state-wide EDWS Plan.

An EDWS Plan is an important tool that will allow for optimum coordination with the state Emergency Management Agency and other stakeholders. The plan maps out emergency water supply needs and other logistics to be coordinated during drinking water incidents. It also details how a state will locate, secure, and deliver an EDWS, specifically outlining the roles and responsibilities of local, state, tribal, and federal agencies, and other stakeholders. This updated guidance also has more information on EDWS distribution management and provides several examples and case studies to assist state primacy agencies in developing robust EDWS Plans that fully comply with 40 CFR 142, Subpart B.
