Wells: EPA lists 7 active wells. ODNR well logs locate 4 public-supply wells inside Kenton City's wellhead protection zone, 255 to 315 ft deep, in limestone. Zoom in to see them as dots.

Kenton sits directly on the Scioto River headwaters, so its 7 wells plausibly tap a Scioto River valley sand-and-gravel aquifer, but the city's CCR/well-field location could not be confirmed in available sources; kept as SDWIS 'local wells' hypothesis with low confidence.

Did you know
  • Kenton sits on the headwaters of the Scioto River, but its water does not come from the river valley at all - all seven city wells draw on the carbonate limestone aquifer of northwest Ohio.
  • Kenton's own 2025 water quality report lists CCR content violations in four separate years - 2018, 2020, 2023 and 2024 - including a 2024 report in which the fluoride number was wrong and barium and cyanide were left…
  • The city's report states plainly that Kenton 'currently has no program in place' to act on its Ohio EPA source water assessment.
  • Ohio EPA has ordered Kenton to submit, by September 1, 2026, a feasibility study on whether to build an entirely new treatment plant or hand its water over to a regional system.
  • Rebuilding the water and sewer lines under downtown Kenton is estimated at $16-20 million in total; the $5 million state grant announced in 2023 covers a single phase.

History6
  • 2018Kenton's 2018 CCR omitted gross alpha and radium-228 data from the table of detected contaminants (disclosed later as a past CCR content violation).
  • 2020The 2020 CCR omitted gross alpha data and listed contaminants that had not been detected.
  • 2023Ohio awards Kenton a $5 million Ohio BUILDS Water Infrastructure Grant (announced July 21, 2023) for Phase 2 of the Historic Courthouse District project - nine downtown blocks of water, storm and…
  • 2023The 2023 CCR wrongly printed radium-228 at 2.7 pCi/L and gross alpha at 0.88 pCi/L (both were actually non-detects) and omitted unresolved significant deficiencies.
  • 2024Ohio EPA informs Kenton on December 31, 2024 of a significant deficiency for failing to report the most recent gross alpha and radium-228 data on the 2023 CCR; the city corrects it in the 2024 CCR…
  • 2024The 2024 CCR is itself found deficient: the fluoride figure was incorrect, barium and cyanide were left out, and unresolved significant deficiencies were not disclosed.

Treatment & pressure

How it is treated

Seven city wells draw on the carbonate aquifer of northwest Ohio - not a Scioto River valley sand-and-gravel aquifer, despite Kenton sitting on the Scioto headwaters. Water is treated at the city's groundwater plant with chlorination (2025 average total chlorine 0.758 ppm), fluoridation, and…

Supply stress

Kenton's own CCR says its seven wells 'ensure an adequate supply of water for future needs and growth,' and Ohio EPA rates the carbonate aquifer's susceptibility to contamination as MODERATE, based on the presence of significant contaminant sources inside the protection area. The city states outright that it has no program in place to…

Sewers

Sanitary

The City of Kenton operates its own wastewater treatment plant, but publishes essentially nothing about it - the city's wastewater plant page is a 'coming soon' placeholder, and no design flow, peak capacity, treatment process, receiving stream or NPDES/consent-decree detail could be substantiated from any retrievable source. Phase 2 of…

Storm

Downtown storm sewer mains are being replaced alongside water and sanitary mains in the $5 million Ohio BUILDS-funded Historic Courthouse District project. No separate stormwater utility fee was identified.
