What Makes Carnot-Moon's Water Unique?
Local geology and source profile
Carnot-Moon, Pennsylvania, in Allegheny County — an Allegheny County unincorporated community (Moon Township) adjacent to Imperial and Coraopolis near Pittsburgh International Airport — receives its water from Pennsylvania American Water, drawing from the Allegheny River through the southwest Pennsylvania distribution.
The soft 97 mg/L hardness and TDS of 160 mg/L reflect the Allegheny County Allegheny River supply's soft character — the Pennsylvanian Pottsville Formation and Devonian Chemung Formation are slightly calcareous clastic sedimentary rocks in the Pittsburgh area Appalachian Plateau, and the Allegheny River at Pittsburgh averages quite soft from its forested Appalachian headwaters (compare Imperial PA: 95/156 in Allegheny County comparable; Coraopolis PA: 99/164 in Allegheny County comparable; Carnot-Moon consistent soft from the same Allegheny County Allegheny River supply). The Allegheny watershed — Pennsylvanian Pottsville Formation (slightly calcareous — primary hardness contributor), Devonian Chemung Formation (calcareous — secondary contributor), and Quaternary Allegheny alluvium (slightly calcareous — minor TDS).
At 97 mg/L with TDS 160, Carnot-Moon's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 5.1 ppt is moderate — a certified drinking water filter provides added protection. Review Pennsylvania American Water's annual water quality report.
Geology & Source: Carnot-Moon in Allegheny County draws from the Pennsylvania American Water on the Allegheny River (Allegheny County, southwest Pennsylvania) — the Allegheny watershed drains Pennsylvanian Pottsville Formation (slightly calcareous) and Devonian Chemung Formation (calcareous) — Pennsylvania Allegheny County Allegheny River supply produces soft water at 97 mg/L with TDS 160 mg/L.
