About this area's water

Did you know
- Maysville Regional Water is a private district with no website: EPA's national inventory lists its contact as a P.O. box in White Cottage and a Gmail address.
- One of its former drinking water sources was literally a flooded quarry - the Frazers Quarry intake, retired in February 2026 along with the Kent Run intake.
- The system has been cited for exceeding the trihalomethane limit in 39 separate quarters since 2014, and was still in violation as of the first quarter of 2026.
- In February 2026 the district switched its own treatment plant off for good and became a pure reseller, buying every gallon from Muskingum County's wells north of Duncan Falls.
History5
- 2009Maysville Regional Water's Lake Isabella surface intake is deactivated, leaving the Kent Run and Frazers Quarry intakes as the district's raw water sources (EPA SDWIS facility record).
- 2014The first of a long run of quarterly TTHM maximum contaminant level violations is recorded (Q3 2014, 0.094 mg/L against an 0.080 mg/L MCL).
- 2018Ohio EPA and the district enter negotiated Director's Final Findings and Orders over the system's compliance problems.
- 2024Ohio EPA issues amended Director's Final Findings and Orders and a conditioned license to operate for the system.
- 2026On February 12 the district's Kent Run and Frazers Quarry intakes, its treatment plant pumps and its finished-water clearwells are all deactivated; Maysville switches entirely to purchased…

How it is treated
None of its own any more. Until February 2026 Maysville Regional Water treated its own surface water drawn from the Kent Run and Frazers Quarry intakes (and, until 2009, Lake Isabella) at its own plant. Since 2026-02-12 those intakes, the intermediate and high-service pumps and the finished-water…

Supply stress
Not a supply-quantity problem but a supply-quality and single-point-of-failure problem. The district's own reservoir and quarry sources produced water with such persistent disinfection byproducts that it has been in and out of TTHM violation since 2014 and is in open violation now, under Ohio EPA findings and orders. Having retired its…
Sewers
Sanitary
Muskingum County's sewer department describes the Maysville area as served by a septic tank effluent system: a septic tank at each customer's site removes settleables and floatables, and the effluent is collected in small-diameter lines laid at flatter slopes. County-wide the sewer system serves more than 5,400 homes and businesses over…
