Fox Chase Water Hardness & Quality Report (2026)

Philadelphia Water Department (PWD) serves Fox Chase in Northeast Philadelphia, Pennsylvania, drawing from the Schuylkill and Delaware River reservoirs including the Queen Lane, Belmont, and Torresdale treatment plants. Primary sources are the Schuylkill River (via reservoirs like Green Lane and Blue Marsh) and Delaware River intakes at Baxter and Torresdale. Fox Chase falls within PWD's Northeast Water Pollution Control Plant service area, covering Philadelphia County with over 1.6 million customers. Treatment involves conventional processes at plants with capacities exceeding 1 billion gallons daily.

The Delaware River Watershed spans 14,000 square miles across Pennsylvania, New York, New Jersey, and Delaware, fed by tributaries like the Schuylkill. Underlying Paleozoic bedrock — Devonian Catskill Formation sandstones and Mississippian limestones — dissolves readily, yielding a hard supply rich in calcium and magnesium. No major aquifers are tapped; surface water dominates, with geology promoting mineral pickup during transit through fractured rock and glacial till, resulting in characteristically hard water without natural softening.

Very hard water promotes scale buildup in pipes, heaters, and fixtures, reducing efficiency by up to 24% and shortening appliance life. Hot water heaters, dishwashers, washing machines, and coffee makers suffer most, with visible deposits on faucets and glassware. Regular vinegar descaling, low-flow aerators, and magnetic descalers help; a water softener is strongly recommended. Water meets all EPA standards with pH at 8.2, lead below 0.007 mg/L, and TDS estimated at 433.7 mg/L. Treatment includes coagulation, sedimentation, filtration, chloramination, and fluoride addition.
