Water Quality Snapshot: NAPLES WATER DEPT

NAPLES WATER DEPT is a local-owned community water system that delivers drinking water to 82,000 residents in NAPLES, Florida (Collier County) through 16,400 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 46 total violations for this system , of which 8 (17%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 12 monitoring and reporting violations are on file. The most recent violation on record dates to 2024.

The most frequently cited contaminant at this system is E. COLI, recorded in 10 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 5 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 0.011 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Florida, EPA tracks 5,093 public water systems serving 22,381,282 people, with 184,355 cumulative violations and 24,266 health-based violations on record. About 93% of systems in the state carry at least one violation, and state-wide the average per system is 36.2 violations. NAPLES WATER DEPT's 46 violations sit above the Florida average. Statewide, 218 of 402 UCMR5-tested systems have reported PFAS detections (54.2%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
