Water Quality Snapshot: JAYUYA URBANO

JAYUYA URBANO is a local-owned community water system that delivers drinking water to 7,644 residents in JAYUYA, Puerto Rico (Jayuya Municipio County) through 2,863 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 302 total violations for this system , of which 116 (38%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 167 monitoring and reporting violations are on file. The most recent violation on record dates to 2020.

The most frequently cited contaminant at this system is Surface Water Treatment Rule, recorded in 57 violations (TT, health-based). Under EPA's UCMR5 PFAS monitoring program, 2 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 0.0124 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

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. JAYUYA URBANO's 302 violations sit below 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.
