Figures here are the current EPA SDWIS extract joined to the 1 community water system whose service area lists Oil City, ranked against the 329 Louisiana places with at least one system on file. Data current as of 2026-08-25.

Water system data comes from the EPA's Safe Drinking Water Information System (SDWIS). PlainEnviro's violation fetch is restricted upstream to records EPA flags as health-based and then joined to active community water systems. Monitoring and reporting violations are not included.

A health-based violation row in this extract is a historical EPA registry entry. It does not describe water delivered today or current compliance status. Many records are later resolved, and public water systems notify customers when required. For current conditions, contact your local water utility or the state drinking water program.
