What Makes Forestville's Water Unique?
Local geology and source profile
Forestville, Ohio, in Hamilton County — a Hamilton County community adjacent to Anderson Township and Milford on the Ohio River corridor in east Cincinnati — receives its water from the Greater Cincinnati Water Works, drawing from the Ohio River through the southwest Ohio distribution.
The very hard 245 mg/L hardness and high TDS of 634 mg/L reflect the Hamilton County supply's very hard calcareous character — the Ordovician Cincinnatian Limestone and Silurian Clinton Formation are highly calcareous formations in the Cincinnati Arch, and the Ohio River acquires substantial dissolved mineral content from its extensive Appalachian-limestone drainage (compare Anderson Township OH: 241/622 in Hamilton County comparable; Milford OH: 248/646 in Clermont County comparable; Forestville consistent very hard from the same Hamilton County Ohio River Ordovician calcareous supply). The Ohio River at Hamilton County — Ordovician Cincinnatian Limestone (highly calcareous — primary hardness contributor), Silurian Clinton Formation (calcareous — secondary contributor), and Quaternary Ohio River alluvium (calcareous — TDS contributor).
At 245 mg/L with TDS 634, Forestville's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 9.7 ppt is very elevated — a certified filter with PFAS removal is strongly recommended. Review Greater Cincinnati Water Works' annual water quality report.
