What Makes Trenton's Water Unique?
Local geology and source profile
Trenton, Ohio, in Butler County — a Butler County city adjacent to Middletown and Hamilton on the Great Miami River in southwest Ohio — receives its water from the City of Trenton Water, drawing from the Great Miami River (Butler County) through the southwest Ohio distribution.
The hard 177 mg/L hardness and TDS of 367.8 mg/L reflect the southwest Ohio Butler County Great Miami River supply's hard dolomitic character — the Silurian Niagaran Dolomite and Ordovician Cincinnatian Series limestone produce hard water throughout the Great Miami valley communities (compare Loveland OH: 238.5/606 in Hamilton County harder on the Little Miami-Ohio River draw; Trenton softer from the upper Great Miami Butler County reach). The Great Miami River at Butler County — Silurian Niagaran Dolomite (highly dolomitic — primary hardness contributor), Ordovician Cincinnatian Series limestone (calcareous — secondary contributor), and Quaternary Great Miami alluvium (calcareous — TDS contributor).
At 177 mg/L with TDS 368, Trenton's water is hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 6.9 ppt warrants a certified drinking water filter — the Butler County southwest Ohio industrial corridor contribute to Trenton's elevated readings.
Geology & Source: Trenton in Butler County is served by City of Trenton Water drawing from the Great Miami River — the Great Miami watershed drains Silurian Niagaran Dolomite (highly dolomitic) and Ordovician Cincinnatian limestone (calcareous) — OH Butler County Great Miami River Silurian dolomitic supply produces hard water at 177 mg/L with TDS 367.8 mg/L.
