University City Water Hardness & Quality Report (2026)

University City, Pennsylvania, in Philadelphia County — a Philadelphia County neighborhood adjacent to West Philadelphia and Spruce Hill near the University of Pennsylvania and Drexel University campus corridor — receives its municipal water from the Philadelphia Water Department (PWD), drawing from the Schuylkill River at the Queen Lane Water Treatment Plant or the Delaware River at the Baxter Plant (both Philadelphia).

The moderately hard 112.5 mg/L hardness and TDS of 196 mg/L are softer than other Philadelphia neighborhood readings (Tacony: 135.5 mg/L, Hunting Park: 141 mg/L), suggesting University City may receive a greater proportion of the Delaware River softer supply (which draws more Piedmont crystalline insoluble water from the Wissahickon and north Delaware tributaries). Philadelphia's distribution system blends Delaware and Schuylkill River sources across distribution zones.

At 112.5 mg/L, University City's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 5.7 ppt warrants a certified drinking water filter — the Philadelphia West University industrial corridor, Naval Air Station Willow Grove (AFFF), and the Delaware Valley PFAS background contribute to University City's readings.
