What Makes Wayne's Water Unique?
Local geology and source profile
Wayne, Pennsylvania, in Delaware County — a major Philadelphia Main Line suburban community (Wayne is one of the most prestigious Philadelphia Main Line communities — a Delaware County community on the Main Line (the historic Pennsylvania Railroad Main Line corridor from Philadelphia west through the most affluent western Philadelphia suburbs: Overbrook, Merion, Wynnewood, Ardmore, Haverford, Bryn Mawr, Wayne, Strafford, Devon, Berwyn); Wayne is a significant retail and commercial hub of the Main Line corridor, with a charming downtown village, high-end residential neighborhoods, and some of the most expensive real estate in Pennsylvania), a diverse Delaware County community with a primarily affluent professional, old-money Philadelphia WASP, and Main Line socially prominent population, home of significant independent schools (St. David's Episcopal Church — one of the historic Main Line congregations — and numerous private schools), and adjacent to the Valley Forge National Historical Park — draws its municipal water supply via Aqua Pennsylvania. Water hardness in Wayne measures 165.5 mg/L — classified as hard.
Wayne's hard supply reflects the northwest Philadelphia Main Line Piedmont watershed geology. The Aqua PA system draws from the Schuylkill River watershed draining Precambrian Wissahickon Schist and Philadelphia Gneiss (calcareous-moderate), producing the hard 165.5 mg/L.
At 165.5 mg/L, Wayne residents face regular hard water challenges. Monthly descaling is recommended. Aqua Pennsylvania consistently delivers water meeting all Pennsylvania DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Schuylkill River watershed (Pamoja and Unami Reservoirs) via the Aqua Pennsylvania (Aqua PA) — the Delaware County northwest Philadelphia suburban Wayne corridor (Precambrian calcareous-moderate Philadelphia Gneiss and Wissahickon Schist — the calcareous-moderate northwest Philadelphia Main Line Piedmont watershed; Aqua PA northwest Philadelphia suburban distribution to Wayne zone); hard supply at 165.5 mg/L in Delaware County.
