What Makes Tonawanda's Water Unique?
Local geology and source profile
Tonawanda, New York, in Erie County — a Erie County city adjacent to North Tonawanda and Kenmore on the Niagara River in western New York — receives its water from the Erie County Water Authority (ECWA), drawing from Lake Erie (Erie County) through the Buffalo metro distribution.
The moderately hard 141.5 mg/L hardness and TDS of 333.2 mg/L are consistent with other ECWA Erie County communities (Kenmore: 147.5 mg/L) — reflecting the same western New York Lake Erie Silurian dolomite character. Lake Erie at Erie County receives drainage from the Great Lakes Basin — Silurian Lockport Dolomite (dolomite — primary TDS contributor), Silurian Niagara Group (calcareous — primary hardness contributor), and Devonian Hamilton Formation (calcareous shale). The Silurian dolomite and calcareous input produce the moderately hard western New York supply.
At 141.5 mg/L, Tonawanda'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 7.0 ppt warrants a certified reverse osmosis drinking water filter — Niagara Falls Air Reserve Station (Niagara County — AFFF, the primary western New York PFAS source), the Niagara River chemical industrial corridor (former Hooker Chemical and Love Canal legacy), and the Lake Erie industrial PFAS background contribute to Tonawanda's elevated readings.
Geology & Source: Tonawanda in Erie County draws from the Erie County Water Authority on Lake Erie (Erie County, western New York) — Lake Erie receives drainage from Silurian Lockport Dolomite and Silurian Niagara Group calcareous — New York Erie County Lake Erie Silurian dolomite watershed produces moderately hard water at 141.5 mg/L with TDS 333.2 mg/L in this Erie County New York city.
