What Makes Dunmore's Water Unique?
Local geology and source profile
Dunmore, Pennsylvania, in Lackawanna County — a Lackawanna County borough adjacent to Scranton in northeast Pennsylvania — receives its water from the Scranton-Dunmore Water System, drawing from Elmhurst Reservoir (Lackawanna County) through the Scranton metro distribution.
The hard 177.5 mg/L hardness and TDS of 411.5 mg/L reflect the northeast Pennsylvania Lackawanna County Pocono Plateau supply's hard calcareous character — reflecting the Elmhurst Reservoir watershed's contact with calcareous Silurian Clinton Group limestones beneath the Devonian-Mississippian insoluble shale and sandstone cap, producing elevated calcareous hardness typical of the Scranton metro supply. The Elmhurst watershed at Lackawanna County — Silurian Clinton Group limestone (calcareous — primary hardness contributor), Devonian Catskill Formation (insoluble — dilutant), and Mississippian Pocono Formation (insoluble — dilutant).
At 177.5 mg/L with TDS 412, Dunmore'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 9.1 ppt warrants a certified drinking water filter — the Lackawanna County Scranton metro industrial corridor contribute to Dunmore's elevated readings.
Geology & Source: Dunmore in Lackawanna County draws from the Scranton-Dunmore Water System on Elmhurst Reservoir (Lackawanna County, northeast Pennsylvania) — the Elmhurst watershed drains the Pocono Plateau (Devonian Catskill Formation — insoluble) and Mississippian Pocono Formation (insoluble) over calcareous Silurian Clinton Group — Pennsylvania Lackawanna County Elmhurst Devonian-Silurian calcareous supply produces hard water at 177.5 mg/L with TDS 411.5 mg/L.
