The Safe Drinking Water Information System (SDWIS) contains information about public water systems and their violations of EPA's drinking water regulations, as reported to EPA by the states. Each year, EPA reports drinking water violations at America's public water systems (PWS). The 1996 Safe Drinking Water Act (SDWA) requires the Administrator to annually prepare a publicly available national compliance report summarizing PWS’s violations reported by primacy agencies (i.e., states, tribes, and territories). The national compliance report also separately summarizes:
1. the violations at systems in Indian country;
2. EPA's enforcement and compliance assistance activities with respect to tribal systems;
3. recommendations for improving compliance; and
4. the financial assistance EPA provided to the tribes that they may have direct access to safe drinking water.
The target audiences for the national report are the drinking water regulators and environmental professionals, although anyone interested in a summary of PWS compliance may find the report useful.The Enforcement and Compliance History Online (ECHO) Drinking Water Dashboard presents the national PWS compliance report in an interactive format. Beginning with calendar year 2014 data, users can access summarized national statistics as well as individual violations and enforcement responses reported by the primacy agencies. Each dashboard report shows the annual compliance data to provide context either at the national level or within a state, tribe, or territory. Note: For the Drinking Water Dashboard the user should ensure for the “Year View” drop down menu that the calendar option is selected.
