What Makes West Carrollton City's Water Unique?
Local geology and source profile
West Carrollton City, Ohio, in Montgomery County — a Montgomery County city adjacent to Dayton and Miamisburg on the Great Miami River in southwest Ohio — receives its water from the Dayton Water Department, drawing from the Great Miami River (Montgomery County) through the Dayton metro distribution.
The moderately hard 109.5 mg/L hardness and TDS of 172.2 mg/L reflect the southwest Ohio Montgomery County Great Miami River supply's moderate dolomitic character — consistent with the Dayton metro Great Miami corridor (compare Englewood OH: 110.5 mg/L; Monroe OH: 116 mg/L), all drawing from the same Great Miami River buried valley aquifer system underlain by the Silurian dolomite platform. The Great Miami River at Montgomery County — Silurian Lockport Dolomite (dolomitic — primary hardness contributor from buried valley aquifer), Ordovician Galena Dolomite (dolomitic — secondary contributor), and Quaternary Great Miami alluvium (slightly calcareous — TDS contributor).
At 109.5 mg/L, West Carrollton's water is moderately 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 4.2 ppt warrants a certified drinking water filter — the Montgomery County Dayton metro industrial corridor contribute to West Carrollton's readings.
