What Makes Circleville's Water Unique?
Local geology and source profile
Circleville, Ohio, in Pickaway County — the Pickaway County seat adjacent to Columbus and Chillicothe on the Scioto River in south-central Ohio — receives its water from the Circleville Water Department, drawing from the Scioto River (Pickaway County) through the south-central Ohio water treatment system.
The very hard 200 mg/L hardness and TDS of 450.1 mg/L reflect the south-central Ohio Pickaway County Scioto River supply's very hard calcareous character — consistent with other Ohio Scioto basin communities and the Washington Court House Pickaway neighbor (250.5 mg/L) driven by the Ordovician Trenton Limestone dissolution through deep calcareous glacial till. The Scioto River at Pickaway County — Ordovician Trenton Limestone (calcareous — primary hardness contributor), Ordovician Black River Limestone (calcareous — secondary contributor), and Quaternary calcareous glacial till from Ordovician-Silurian carbonate bedrock.
At 200 mg/L, Circleville's water is very hard — scale builds rapidly in kettles and appliances, a water softener is beneficial, and water heaters should be inspected annually. Monthly descaling is recommended. The PFAS level of 7.8 ppt warrants a certified drinking water filter — Wright-Patterson Air Force Base (Greene County — AFFF) and the south-central Ohio industrial corridor contribute to Circleville's elevated readings.
Geology & Source: Circleville in Pickaway County draws from the Circleville Water Department on Hargus Creek or the Scioto River (Pickaway County, south-central Ohio) — the Scioto at Pickaway drains the Ohio Till Plains (Ordovician Trenton Limestone — calcareous) through deep calcareous glacial till — Ohio Pickaway County Scioto River Ordovician calcareous till Plains watershed produces very hard water at 200 mg/L with TDS 450.1 mg/L.
