What Makes Mount Lebanon's Water Unique?
Local geology and source profile
Mount Lebanon, Pennsylvania, in Allegheny County — a major south Pittsburgh suburban community (Mount Lebanon is one of the most prestigious south Pittsburgh suburbs — an affluent Allegheny County community known for its excellent public school district, Victorian and Craftsman architecture, and one of the higher property values in the Pittsburgh metro area), home of one of the most highly rated public school districts in Pennsylvania (Mount Lebanon School District consistently achieves among the highest standardized test scores in Pennsylvania), a diverse Allegheny County community with a significant professional and academic population (many University of Pittsburgh and Carnegie Mellon University faculty reside in Mount Lebanon), and a community with a distinctive early 20th century planned suburban character — draws its municipal water supply via the Pennsylvania American Water. Water hardness in Mount Lebanon measures 130.5 mg/L — classified as moderately hard.
Mount Lebanon's moderate hardness reflects the south Pittsburgh Allegheny County supply characteristics. The Pennsylvania American Water (Ohio River–Monongahela River system — draining the Pennsylvanian Pittsburgh Coal Measures, calcareous-moderate) distributes to the Mount Lebanon south Allegheny zone, producing the moderate 130.5 mg/L.
At 130.5 mg/L, Mount Lebanon residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended. Pennsylvania American Water consistently delivers water meeting all Pennsylvania DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Ohio River (Monongahela and Allegheny Rivers) via the Pennsylvania American Water — the Allegheny County south Pittsburgh suburban Mount Lebanon corridor (Pennsylvanian calcareous-moderate Pittsburgh Coal Measures — the calcareous-moderate southwest Pennsylvania Carboniferous Coal Measures; Pennsylvania American Water south Allegheny distribution to Mount Lebanon zone); moderately hard supply at 130.5 mg/L in Allegheny County.
