What Makes Halfway's Water Unique?
Local geology and source profile
Halfway, Maryland, in Washington County — a Washington County unincorporated community adjacent to Hagerstown and Maugansville in the Cumberland Valley of west Maryland — receives its water from Washington County Utilities or City of Hagerstown, drawing from the Potomac River and Hagerstown Valley wells through the west Maryland distribution.
The hard 184 mg/L hardness and TDS of 468.5 mg/L reflect the Washington County supply's hard Valley and Ridge character — the Cambrian Tomstown Formation and Ordovician Rockdale Run Formation are calcareous formations in the Hagerstown Valley's limestone-dolomite belt, and the Cumberland Valley groundwater acquires hard dissolved mineral content from the Appalachian carbonate corridor (compare Hagerstown MD: 180/457 in Washington County comparable; Maugansville MD: 187/479 in Washington County comparable; Halfway consistent hard from the same Washington County Potomac River Cambrian calcareous supply). The Hagerstown Valley supply — Cambrian Tomstown Formation (calcareous — primary hardness contributor), Ordovician Rockdale Run Formation (calcareous — secondary contributor), and Quaternary Cumberland Valley alluvium (calcareous — TDS contributor).
At 184 mg/L with TDS 469, Halfway's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 10.1 ppt is very high — a certified filter with PFAS removal is strongly recommended. Review Washington County Utilities' annual water quality report.
Geology & Source: Halfway in Washington County draws from the Hagerstown Water on the Potomac River supply (Washington County, west Maryland) — the Hagerstown Valley supply draws from Cambrian Tomstown Formation (calcareous) and Ordovician Rockdale Run Formation (calcareous) — Maryland Washington County Potomac River Cambrian calcareous supply produces hard water at 184 mg/L with TDS 468.5 mg/L.
