Water Quality Snapshot: MAYSVILLE REGIONAL WATER

MAYSVILLE REGIONAL WATER is a private-owned community water system that delivers drinking water to 6,540 residents in WHITE COTTAGE, Ohio (Muskingum County) through 2,414 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 406 total violations for this system , of which 217 (53%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 165 monitoring and reporting violations are on file. The most recent violation on record dates to 2025.

The most frequently cited contaminant at this system is TTHM, recorded in 186 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 0.004 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Ohio, EPA tracks 4,181 public water systems serving 11,085,226 people, with 288,388 cumulative violations and 52,412 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 69 violations. MAYSVILLE REGIONAL WATER's 406 violations sit above the Ohio average. Statewide, 204 of 346 UCMR5-tested systems have reported PFAS detections (59%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
