Wissinoming Water Hardness & Quality Report (2026)

Wissinoming, Pennsylvania, in Philadelphia County — a historic Northeast Philadelphia neighborhood along Torresdale Avenue and the Frankford Creek corridor, a working-class rowhouse neighborhood with deep Polish, Ukrainian, and Italian American community roots — receives its municipal water from the Philadelphia Water Department (PWD), which draws from the Schuylkill River at the Queen Lane intake and the Delaware River at the Baxter Water Treatment Plant. All of Philadelphia, from Center City to the Northeast, receives the same PWD dual-river supply.

The moderately hard 112.5 mg/L hardness and TDS of 195.8 mg/L reflect Philadelphia's PWD supply in the Northeast Philadelphia distribution zone. The Schuylkill River drains the Reading Prong (Precambrian Grenville gneiss — crystalline, low-carbonate) and the Valley and Ridge carbonate zone (Devonian and Ordovician limestone and dolomite of the Pennsylvania anthracite country), while the Delaware River drains the Catskill Mountain shale-sandstone watershed. PWD's blended and treated supply produces consistently moderate hardness throughout Philadelphia, and the Wissinoming Northeast zone shows typical finished water character consistent with the PWD Northeast distribution loop.

At 112.5 mg/L, Wissinoming's water is moderately hard — consistent with the Northeast Philadelphia PWD supply. Scale builds in kettles and appliances over months, the dishwasher benefits from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling of heating appliances is the standard schedule. The PFAS level of 5.6 ppt is moderate for Philadelphia — the PWD's active PFAS monitoring and treatment program, the Schuylkill and Delaware watershed upstream industrial sources, and Philadelphia's refinery and chemical corridor all contribute to the background.
