What Makes Aspen Hill's Water Unique?
Local geology and source profile
Aspen Hill, Maryland, an unincorporated community in Montgomery County — a major Montgomery County inner suburb north of Wheaton with significant Jewish-American, Salvadoran-American, and Ethiopian-American populations, part of the dense Montgomery County suburban corridor along Georgia Avenue — draws its municipal water supply from the Potomac River via the Washington Suburban Sanitary Commission (WSSC). Water hardness in Aspen Hill measures 95.5 mg/L — classified as moderately soft.
Aspen Hill's moderate softness reflects the WSSC Potomac River supply in the Montgomery County distribution. The Potomac River above Washington draws from: the West Virginia Allegheny Mountains (Devonian–Silurian calcareous-poor shale and sandstone of the Allegheny Front — calcareous-poor); the Virginia–Maryland Catoctin Formation (Proterozoic metavolcanic greenstone — calcium-moderate mafic rock); and the Maryland Piedmont crystalline (calcareous-poor gneiss). WSSC applies advanced treatment (coagulation, filtration, and lime softening) at its Potomac and Patuxent Water Filtration Plants, producing the moderate 95.5 mg/L in the Montgomery County distribution zone.
With hardness at 95.5 mg/L, Aspen Hill residents enjoy moderately soft water with minimal scale challenges. WSSC consistently delivers water meeting all Maryland MDE and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Potomac River via the Washington Suburban Sanitary Commission (WSSC) — the Montgomery County Maryland upper Potomac River corridor (Blue Ridge–Catoctin Formation and Piedmont crystalline terrain watershed); moderately soft supply at 95.5 mg/L in Montgomery County.
