Water Quality Snapshot: Ringwood Water Department
Ringwood Water Department is a local-owned community water system that delivers drinking water to 9,327 residents in Ringwood, New Jersey (Passaic County) through 3,195 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 644 total violations for this system , of which 29 (5%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 600 monitoring and reporting violations are on file. The most recent violation on record dates to 2025.
The most frequently cited contaminant at this system is Xylenes, Total, recorded in 24 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 8 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 12.3 ppt (parts per trillion). PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.
Across New Jersey, EPA tracks 3,428 public water systems serving 9,570,926 people, with 204,988 cumulative violations and 22,229 health-based violations on record. About 95% of systems in the state carry at least one violation, and state-wide the average per system is 59.8 violations. Statewide, 208 of 264 UCMR5-tested systems have reported PFAS detections (78.8%).
Ringwood Water Department's 644 violations sit above the New Jersey average.
All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
