About this area's water
Did you know
- West Jefferson softens its drinking water with reverse osmosis — four RO skids since the 2018 plant upgrade — and the village claims the result is 'some of the highest quality water in the state of Ohio.' RO softening…
- The village's 1872 town seal pictured the original covered bridge that carried the National Road over Little Darby Creek — the same creek the village's wastewater plant discharges into today.
- West Jefferson's wastewater plant is literally at the end of Sewer Lane, tucked behind the Community Center, and takes about 61 hours to move waste through seven processes.
- The village's February 2026 charter review notes discuss changes to take up 'after the Village becomes a city,' and put total outstanding village debt at $11,154,403 as of December 31, 2024.
- Sampling in 2025 covered 49 different contaminants, most of which were not detected.

- 2006Source water assessment study completed for the village wellfield; a copy remains available for public inspection at the water department.
- 2018Water treatment plant upgrade begun: two additional reverse-osmosis skids (four total), two additional sand filters (four total), a larger high-service clear well, a new booster pump station and a…
- 2018Village monitored finished water for radon.
- 2020Sampled under Ohio's PFAS initiative — six PFAS compounds, none detected; also voluntarily sampled raw and finished water for hexavalent chromium, all results below 0.010 mg/L.

Treatment & pressure
How it is treated
Four wells adjacent to the northeast corner of the water treatment plant at 199 Taylor Blair Road supply the village. Water is aerated as it comes out of the wells to oxidize iron and manganese; the oxidized metals and other particulates are removed by sand filtration; the water is then softened by…

Water pressure
Not published. The 2025 CCR describes a new booster pump station and a larger high-service clear well from the 2018 upgrade but gives no system pressure figure, and no…

Supply stress
The 2025 CCR states plainly that the aquifer supplying West Jefferson has a high susceptibility to contamination: although the production aquifer is deep, the surface deposits give it limited protection, as shown by elevated sodium and chloride levels detected in the village's wells. Thirteen potential contaminant sources have been…
