- Sand and gravel (glacial outwash/buried valley) aquifer
- Active wells
- 9
- Serves
- 8,400 people · Preble County

No specific named well field found for the city system itself; regional groundwater in the area is documented as sand-and-gravel Pleistocene aquifer over Silurian-Devonian bedrock, but this is inferred from nearby monitoring wells rather than confirmed for Eaton's own wellfield.
About this area's water
Did you know
- Eaton runs two water plants with different jobs: the Eaton Water Plant (3 wells) only strips iron, while the Black Water Plant (5 wells) removes both iron and manganese, dosing potassium permanganate to do it.
- One tank does most of the work -- the city's own annual report warns that if the 1.5 MG elevated tank goes out of service, normal fire flows could be a problem in a major fire. The other tank holds 0.75 MG.
- About 3,700 accounts are served by roughly 55 miles of main ranging from 2 to 12 inches, with around 475 fire hydrants.
- In 2020 Ohio EPA tested Eaton's finished water for six PFAS compounds under a statewide initiative and detected none.
- Eaton's wastewater plant treated 486 million gallons in 2025 and still averaged 98-99% removal of CBOD, solids and ammonia.
