Water Quality Snapshot: Caroline Utility System
Caroline Utility System is a local-owned community water system that delivers drinking water to 4,235 residents in Ruther Glen, Virginia (Caroline County) through 1,596 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 32 total violations for this system , of which 4 (13%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 22 monitoring and reporting violations are on file. The most recent violation on record dates to 2019.
The most frequently cited contaminant at this system is Coliform (TCR), recorded in 8 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 3.2 ppt (parts per trillion). PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.
Across Virginia, EPA tracks 2,821 public water systems serving 7,911,199 people, with 146,670 cumulative violations and 25,642 health-based violations on record. About 90% of systems in the state carry at least one violation, and state-wide the average per system is 52 violations. Statewide, 70 of 171 UCMR5-tested systems have reported PFAS detections (40.9%).
Caroline Utility System's 32 violations sit below the Virginia average.
All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
1 PFAS "forever chemicals" detected in testing under EPA's UCMR5 monitoring program.
