What Makes Munhall's Water Unique?
Local geology and source profile
Munhall, Pennsylvania, in Allegheny County — an Allegheny County borough adjacent to Homestead and McKeesport on the Monongahela River south of Pittsburgh — receives its water from Pennsylvania American Water, drawing from the Monongahela River through the southwest Pennsylvania distribution.
The hard 158 mg/L hardness and TDS of 345 mg/L reflect the Allegheny County Monongahela River supply's hard character — the Pennsylvanian Conemaugh Formation and Devonian Catskill Formation are calcareous to highly calcareous formations in the Pittsburgh area Appalachian Plateau, with mine drainage from the Mon Valley coal fields contributing additional dissolved mineral content (compare Homestead PA: 155/338 in Allegheny County comparable; McKeesport PA: 161/352 in Allegheny County comparable; Munhall consistent hard from the same Allegheny County Monongahela River Pennsylvanian calcareous supply). The Monongahela watershed — Pennsylvanian Conemaugh Formation (calcareous — primary hardness contributor), Devonian Catskill Formation (calcareous — secondary contributor), and Quaternary Monongahela alluvium (calcareous — TDS contributor).
At 158 mg/L with TDS 345, Munhall's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 8.3 ppt is elevated — a certified drinking water filter with PFAS removal is recommended — the Allegheny County Pittsburgh steel and industrial Mon Valley legacy contributes to Munhall's elevated PFAS readings.
Geology & Source: Munhall in Allegheny County draws from the Pennsylvania American Water on the Monongahela River (Allegheny County, southwest Pennsylvania) — the Monongahela watershed drains Pennsylvanian Conemaugh Formation (calcareous) and Devonian Catskill Formation (calcareous) — Pennsylvania Allegheny County Monongahela River Pennsylvanian calcareous supply produces hard water at 158 mg/L with TDS 345 mg/L.
