SDWIS
The Safe Drinking Water Information System (SDWIS)/FED (federal version) contains information about public water systems and their violations of Environmental Protection Agency (EPA) drinking water regulations, as reported to EPA by the states. These regulations establish maximum contaminant levels, treatment techniques and monitoring and reporting requirements to ensure that water systems provide safe water to their customers.
SDWIS/STATE (state version) is a database designed by EPA to help states administer and manage their own drinking water programs. SDWIS/STATE is the state counterpart to EPA's federal drinking water information system.
