Water Quality Snapshot: Edison Water Co

Edison Water Co is a local-owned community water system that delivers drinking water to 35,000 residents in Edison, New Jersey (Middlesex County) through 11,810 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 50 total violations for this system , of which 10 (20%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 28 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 Lead and Copper Rule, recorded in 13 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 4 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 5.4 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%).
