About this area's water
Did you know
- Chickasaw historically operated four wells (1E, 2W, 3N, 4S by compass direction), but two (1E, 2W) were taken offline in 2019 — the system now runs on just 3N and 4S, matching modern records rather than the four-well…
- Unlike most villages this size, Chickasaw runs real iron/manganese treatment — greensand and pressure-sand filtration, with pre-ozonation used at its since-retired original plant — rather than just chlorinating raw well…
- EPA facility records show both a current and an 'old' Chickasaw Village treatment plant on file, with the old plant, two of the four original wells, and an old storage tank all deactivated together in 2019, evidence of…
- The village adds an orthophosphate corrosion inhibitor to protect pipes and control lead/copper leaching.

Treatment & pressure
How it is treated
EPA treatment records show the active plant (facility 47315) using greensand filtration, pre- and post-hypochlorination, an orthophosphate corrosion inhibitor, and a reaction step for iron/manganese removal and disinfection. A separate, now-deactivated 'old' plant (facility 5585, retired 2019) is…

Supply stress
System now draws on two active wells (3N, 4S) after wells 1E and 2W were deactivated in 2019 (four wells — 1E, 2W, 3N, 4S — were operated historically). Iron/manganese treatment (greensand filtration, ozonation at the retired plant) suggests naturally mineral-rich groundwater typical of Mercer County's glacial aquifers. No drought or…
