What Makes Monroeville's Water Unique?
Local geology and source profile
Monroeville, Pennsylvania, in Allegheny County — a major east Pittsburgh suburban community (Monroeville is a significant Allegheny County municipality — an east Pittsburgh suburb in the US Route 22 and Pennsylvania Turnpike corridor adjacent to Penn Hills and Plum; Monroeville has a unique place in pop culture history — it is where George A. Romero filmed 'Dawn of the Dead' (1978) at the Monroeville Mall (the Monroeville Mall was the primary filming location for one of the most important horror films in American cinema history; the Monroeville Mall 'Dawn of the Dead' is one of the most celebrated genre films ever made; the mall is now a tourist attraction for horror fans and zombie culture devotees); Monroeville is also a major east Pittsburgh corporate and technology corridor), a diverse Allegheny County community with a significant Indian-American (Monroeville has one of the most significant Indian-American communities in the Pittsburgh metro — there is a substantial South Asian community with temples, restaurants, and cultural institutions in Monroeville), African-American, and working-class suburban population — draws its municipal water supply via the PWSA. Water hardness in Monroeville measures 105 mg/L — classified as moderately hard.
Monroeville's moderate hardness reflects the east Pittsburgh Allegheny County Pennsylvania Coal Measures watershed's calcareous-poor geology with distribution characteristics. The PWSA distributes Allegheny River–Monongahela River blended supply to the east Pittsburgh Monroeville zone, producing the moderate 105 mg/L.
At 105 mg/L, Monroeville residents encounter moderate scale accumulation. Monthly cleaning is recommended. Pittsburgh Water and Sewer Authority consistently delivers water meeting all Pennsylvania DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Allegheny River Basin (Pennsylvania Aquifer — Allegheny County groundwater) via the Pittsburgh Water and Sewer Authority (PWSA) — the Allegheny County east Pittsburgh suburban Monroeville corridor (Pennsylvanian calcareous-poor Conemaugh and Monongahela Groups — the calcareous-poor east Pittsburgh Allegheny County Pennsylvania Coal Measures watershed; effective treatment); moderately hard supply at 105 mg/L in Allegheny County.
