What Makes Shiloh's Water Unique?
Local geology and source profile
Shiloh, Ohio, in Montgomery County — a Montgomery County unincorporated community adjacent to Dayton and Trotwood in the Greater Dayton area of southwest Ohio — receives its water from Montgomery County Water Services or Miami Valley Water, drawing from the Great Miami River through the southwest Ohio distribution.
The very hard 223.5 mg/L hardness and high TDS of 542.7 mg/L reflect the Montgomery County Great Miami River supply's very hard dolomitic character — the Silurian Lockport Dolomite and Ordovician Cincinnatian Group are highly calcareous formations in the Cincinnati-Dayton limestone belt, and the Great Miami River acquires substantial dissolved mineral content from its extensive dolomite drainage (compare Dayton OH: 218/529 in Montgomery County comparable; Trotwood OH: 228/555 in Montgomery County comparable; Shiloh consistent very hard from the same Montgomery County Great Miami River Silurian dolomitic supply). The Great Miami River at Montgomery County — Silurian Lockport Dolomite (highly dolomitic — primary hardness contributor), Ordovician Cincinnatian Group (calcareous — secondary contributor), and Quaternary Miami River alluvium (calcareous — TDS contributor).
At 223.5 mg/L with TDS 543, Shiloh's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 8.8 ppt is elevated — a certified filter with PFAS removal is recommended. Review Montgomery County Water Services' annual report.
