Drinking water in Cayey, Puerto Rico is delivered through 7 EPA-regulated community water systems serving an estimated 21,000 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 36 violation records across the 7 active community systems shown here. Monitoring and reporting records are not present in the extract. The records carry 7 distinct EPA contaminant codes: Revised Total Coliform Rule, LEAD AND COPPER RULE REVISIONS, CARBON, TOTAL, Total Haloacetic Acids (HAA5), TTHM and 2 others. 1 TRI-reporting industrial facility is also located within the city limits.
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. For current water-quality status and treatment practices, review your local utility's most recent Consumer Confidence Report or contact the Puerto Rico drinking water program. All records above reflect federal EPA SDWIS data and are not independently verified against state databases.

About This Data
Figures here are the current EPA SDWIS extract joined to the 7 community water systems whose service area lists Cayey, ranked against the 69 Puerto Rico 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.
TRI facility data comes from the EPA Toxic Release Inventory. Facilities shown are those that self-report to the TRI program. PlainEnviro presents this data without advocacy framing.
