Port Richmond Water Hardness & Quality Report (2026)

The Philadelphia Water Department (PWD) provides water to Port Richmond, a neighborhood in Philadelphia, Pennsylvania, within Philadelphia County, serving over 1.7 million people across the city and suburbs. PWD draws raw water from the Schuylkill River — treated at the Queen Lane, Wissahickon, and Belmont treatment plants — and the Delaware River, treated at the Baxter and Torresdale treatment plants. Port Richmond is served specifically by the Torresdale Water Treatment Plant on the Delaware River.

The primary watersheds are the Schuylkill River Basin (upstream from Perkiomen Creek) and the Delaware River Basin (above Trenton). Water contacts Paleozoic sedimentary rocks including Devonian Catskill Formation sandstones and Hamilton Group shales, plus Mississippian-Pennsylvanian limestones and dolomites from the upstream Piedmont and Valley & Ridge provinces. These carbonate-rich formations dissolve to yield elevated calcium and magnesium, imparting a moderately mineralised, hard character to the surface water supply.

At moderately hard levels, scale buildup affects kettles, dishwashers, and water heaters — reducing efficiency by 20–30% over time — and causes spotting on laundry machines and faucets. Recommended maintenance includes monthly vinegar cleaning of fixtures, installing scale inhibitors, and annual flushing of water heaters; a water softener is advised for households noticing spots or dry skin. PWD water maintains an average pH of 7.5 adjusted for corrosion control; the utility complies with the Lead and Copper Rule (90th percentile copper <1.3 mg/L, lead <15 ppb action level), no PFAS exceedances appear in recent CCRs, and treatment includes coagulation, sedimentation, filtration, chlorination, and fluoridation.
