Water Quality Snapshot: Brookwood Comm Wtr System

Brookwood Comm Wtr System is a private-owned community water system that delivers drinking water to 15,380 residents in Cary, North Carolina (Cumberland County) through 6,152 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 1,529 total violations for this system , of which 1,342 (88%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 75 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 Combined Radium (-226 and -228), recorded in 1,254 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 8 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 63.3 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.
