Water Quality Snapshot: Chatham Co-North
Chatham Co-North is a local-owned community water system that delivers drinking water to 23,088 residents in Sanford, North Carolina (Chatham County) through 9,235 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 321 total violations for this system , of which 107 (33%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 164 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 Coliform (TCR), recorded in 39 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 2 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 4.8 ppt (parts per trillion). PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.
Across North Carolina, EPA tracks 5,020 public water systems serving 9,877,724 people, with 524,053 cumulative violations and 38,492 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 104.4 violations. Statewide, 174 of 287 UCMR5-tested systems have reported PFAS detections (60.6%).
Chatham Co-North's 321 violations sit above the North Carolina average.
All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
2 PFAS "forever chemicals" detected in testing under EPA's UCMR5 monitoring program.
