Drinking water in Cotton Valley, Louisiana is delivered through 1 EPA-regulated community water system serving an estimated 1,380 people. Each system is tracked in the EPA Safe Drinking Water Information System (SDWIS) under the Safe Drinking Water Act, which requires testing for regulated contaminants, consumer notification of violations, and publication of an annual Consumer Confidence Report.
PlainEnviro's health-based SDWIS extract shows 5 violation records across the 1 active community system shown here. Monitoring and reporting records are not present in the extract. The records carry 1 distinct EPA contaminant code: Groundwater Rule. 2 TRI-reporting industrial facilities are also located within the city limits.

All records above reflect federal EPA SDWIS data and are not independently verified against state databases.
