What Makes Sharonville's Water Unique?
Local geology and source profile
Sharonville, Ohio, in Hamilton County — a Hamilton County city adjacent to Cincinnati and Mason in the north Cincinnati metro — receives its water from the Greater Cincinnati Water Works, drawing from the Ohio River (Hamilton County) through the Cincinnati metro distribution.
The very hard 214.5 mg/L hardness and TDS of 506.6 mg/L reflect the southwest Ohio Hamilton County Ohio River supply's very hard calcareous character — typical of Cincinnati metro communities (Circleville: 200 mg/L; Maumee: 233.5 mg/L) driven by the Ordovician Cincinnati Arch limestone dissolution with the Ohio River's calcareous tributary input from Kentucky and the Ohio Valley karst terrain. The Ohio River at Hamilton County — Ordovician Cincinnati Limestone (highly calcareous — primary hardness contributor), Ordovician Eden Shale (slightly calcareous — secondary contributor), and Quaternary calcareous glacial outwash (calcareous — TDS contributor).
At 214.5 mg/L with TDS 506, Sharonville's water is very hard. A water softener is strongly recommended to prevent rapid scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 8.4 ppt warrants a certified drinking water filter — Wright-Patterson Air Force Base (Greene County — AFFF) and the Cincinnati Hamilton County industrial corridor contribute to Sharonville's elevated readings.
Geology & Source: Sharonville in Hamilton County draws from the Greater Cincinnati Water Works on the Ohio River (Hamilton County, southwest Ohio) — the Ohio River at Hamilton County drains the Ohio Valley (Ordovician Cincinnati Limestone — highly calcareous) through thick calcareous glacial till — Ohio Hamilton County Ohio River Ordovician calcareous watershed produces very hard water at 214.5 mg/L with TDS 506.6 mg/L.
