Beavercreek Water Hardness & Quality Report (2026)

Beavercreek, Ohio, in Greene County east of Dayton — a major Dayton east suburban community, home of the National Museum of the United States Air Force (the world's largest aviation museum, at Wright-Patterson Air Force Base), a premier Dayton east suburb with a highly educated Air Force research community, and one of Ohio's wealthiest suburban communities — draws its municipal water supply from the Mad River Valley alluvial aquifer via Greene County Water (Ohio American Water). Water hardness in Beavercreek measures 188 mg/L — classified as hard.

Beavercreek's hard supply reflects the Greene County calcareous glacial outwash terrain. The Mad River–Little Miami River Valley alluvial aquifer at Beavercreek–Greene County is recharged from: Greene County Wisconsin Age calcareous glacial outwash (highly calcareous Tinley and Valparaiso Moraine-era outwash from the Michigan Basin Silurian Niagara Dolomite and Devonian Columbus Limestone terrain); the Silurian Niagara Dolomite subcropping at shallow depth across Greene County (the southwest Ohio Silurian dolomite platform, which is a very calcareous formation); and the Mad River Valley alluvial deposits (calcareous outwash gravel recharging the aquifer). The Silurian dolomite subcrop and calcareous glacial outwash produce the hard 188 mg/L at Beavercreek.

At 188 mg/L, Beavercreek residents face regular hard water challenges. Scale deposits form on faucet aerators, showerheads, and appliances within weeks — monthly descaling with citric acid solution is standard maintenance. Ohio American Water / Greene County Water consistently delivers water meeting all Ohio EPA and federal EPA Safe Drinking Water Act requirements.
