Description:
The EPA’s Safe Drinking Water Information System provides information on public water systems, and their quantity and types of violations of drinking water regulations. Using EPA guidelines, PolicyMap categorizes each violation as a health violation or a monitoring and reporting violation. The source data comes at the agency-level and water systems are identified as serving particular counties. PolicyMap uses the underlying source data to produce county-level indicators. Only water systems that serve 3,300 people or more are included. Violation counts are weighted by the number of people served by each water system to produce population weighted average indicators for each area.
