Water Quality Snapshot: MONROE TWP UTILITY DEPARTMENT

MONROE TWP UTILITY DEPARTMENT is a local-owned community water system that delivers drinking water to 36,000 residents in MONROE TOWNSHIP, New Jersey (Middlesex County) through 22,379 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 538 total violations for this system , of which 15 (3%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 507 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 Xylenes, Total, recorded in 21 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 20.7 ppt. 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. MONROE TWP UTILITY DEPARTMENT's 538 violations sit above the New Jersey average. Statewide, 208 of 264 UCMR5-tested systems have reported PFAS detections (78.8%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
