Drinking water in Cabo Rojo, Puerto Rico is delivered through 1 EPA-regulated community water system serving an estimated 20,356 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 48 violation records across the 1 active community system shown here. Monitoring and reporting records are not present in the extract. The records carry 4 distinct EPA contaminant codes: TTHM, Interim Enhanced Surface Water Treatment Rule, Long Term 2 Enhanced Surface Water Treatment Rule, Total Haloacetic Acids (HAA5).
A past EPA health-based registry row does not describe water delivered today or current compliance status; utilities notify customers and remediate under state primacy oversight when required.
