What Makes Blue Ash's Water Unique?
Local geology and source profile
Blue Ash, Ohio, in Hamilton County — a Hamilton County city adjacent to Sycamore Township and Symmes Township in northeast 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 234.5 mg/L hardness and TDS of 588.4 mg/L reflect the Cincinnati metro Hamilton County Ohio River supply's very hard dolomitic character — the Silurian Niagaran Dolomite and Ordovician Cincinnatian limestone produce very hard water throughout the Ohio River valley communities (compare Loveland OH: 238.5/606 in Hamilton County comparable; Blue Ash essentially the same Greater Cincinnati Water Works supply — the eastern Hamilton County distribution end). The Ohio River at Hamilton County — Silurian Niagaran Dolomite (highly dolomitic — primary hardness contributor), Ordovician Cincinnatian limestone (calcareous — secondary contributor), and Quaternary Ohio alluvium (calcareous — TDS contributor).
At 234.5 mg/L with TDS 588, Blue Ash'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 9.2 ppt warrants a certified drinking water filter — the Hamilton County northeast Cincinnati industrial corridor contribute to Blue Ash's elevated readings.
Geology & Source: Blue Ash in Hamilton County is served by Greater Cincinnati Water Works drawing from the Ohio River — the Ohio River watershed drains Silurian Niagaran Dolomite (highly dolomitic) and Ordovician Cincinnatian limestone (calcareous) — OH Hamilton County Ohio River Silurian dolomitic supply produces very hard water at 234.5 mg/L with TDS 588.4 mg/L.
