Water Quality Snapshot: CENTRAL TERMOELECTRICA
CENTRAL TERMOELECTRICA is a private-owned non-transient non-community water system that delivers drinking water to 390 residents in GUAYANILLA, Puerto Rico (Guayanilla Municipio County) through 146 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 391 total violations for this system , of which 8 (2%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 373 monitoring and reporting violations are on file. The most recent violation on record dates to 2021.
The most frequently cited contaminant at this system is Coliform (TCR), recorded in 102 violations (MR). This system has not yet been sampled under EPA's UCMR5 PFAS monitoring program, so no PFAS detection data is available here.
Across Puerto Rico, EPA tracks 458 public water systems serving 3,328,141 people, with 164,144 cumulative violations and 34,657 health-based violations on record. About 100% of systems in the state carry at least one violation, and state-wide the average per system is 358.4 violations. CENTRAL TERMOELECTRICA's 391 violations sit above the Puerto Rico average. Statewide, 40 of 99 UCMR5-tested systems have reported PFAS detections (40.4%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
