Water Quality Snapshot: CEDRO ARRIBA

CEDRO ARRIBA is a local-owned community water system that delivers drinking water to 5,482 residents in NARANJITO, Puerto Rico (Naranjito Municipio County) through 2,053 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 623 total violations for this system , of which 379 (61%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 207 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 Interim Enhanced Surface Water Treatment Rule, recorded in 232 violations (TT, health-based). This system was sampled under EPA's UCMR5 PFAS monitoring program and no PFAS compounds were detected above the minimum reporting level.

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. CEDRO ARRIBA's 623 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.
