What Makes Geneva's Water Unique?
Local geology and source profile
Geneva, New York, in Ontario County — an Ontario County city adjacent to Seneca Falls and Canandaigua on Seneca Lake in the Finger Lakes region — receives its water from the City of Geneva Water, drawing from Seneca Lake (Ontario County) through the Finger Lakes distribution.
The hard 163 mg/L hardness and TDS of 417.6 mg/L reflect the Finger Lakes Ontario County Seneca Lake supply's hard calcareous character — Seneca Lake's watershed drains the Appalachian Plateau's Devonian limestone and Silurian Lockport Dolomite, producing hard dolomitic water typical of the Finger Lakes communities (compare Jericho NY: 154 mg/L on Long Island glacial; Geneva harder from the Devonian-Silurian calcareous Finger Lakes watershed). The Seneca Lake watershed at Ontario County — Devonian Tully Limestone (calcareous — primary hardness contributor), Silurian Lockport Dolomite (dolomitic — secondary contributor), and Pleistocene glacial till (calcareous — TDS contributor).
At 163 mg/L with TDS 418, Geneva's water is hard. A water softener is recommended to prevent scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 7.9 ppt warrants a certified drinking water filter — the Ontario County Finger Lakes industrial corridor contribute to Geneva's elevated readings.
Geology & Source: Geneva in Ontario County draws from the City of Geneva Water on Seneca Lake (Ontario County, Finger Lakes region, New York) — Seneca Lake at Ontario County drains the Appalachian Plateau (Devonian Tully Limestone — calcareous) and Silurian Lockport Dolomite (dolomitic) — New York Ontario County Seneca Lake Devonian-Silurian Finger Lakes calcareous supply produces hard water at 163 mg/L with TDS 417.6 mg/L.
