Lawndale Water Hardness & Quality Report (2026)

Lawndale, Pennsylvania, in Philadelphia County in the northeast section of Philadelphia near Rhawnhurst and the Frankford commercial corridor, receives its municipal water from the Philadelphia Water Department (PWD), which draws from the Schuylkill River and Delaware River through its three major water treatment facilities: Baxter Water Treatment Plant on the Delaware, Queen Lane Water Treatment Plant on the Schuylkill, and Belmont Water Treatment Plant on the Schuylkill. PWD blends these two river sources and distributes treated water throughout Philadelphia's neighborhoods including northeast communities like Lawndale.

The moderately hard 155 mg/L hardness and TDS of 328.1 mg/L reflect the blended character of Philadelphia's two-river supply. The Schuylkill River drains the Piedmont Province and Valley and Ridge Province of southeastern Pennsylvania — including the Great Valley carbonate corridor (Elbrook Limestone, Conestoga Limestone) and the anthracite coal region with associated carbonate formations — contributing higher dissolved minerals to the blend. The Delaware River draws from a larger mixed watershed spanning New Jersey and New York with moderate hardness. PWD's treatment and blending produces a moderately hard finished supply consistent across Philadelphia's neighborhoods.

At 155 mg/L, Lawndale residents deal with moderately hard water that is familiar across Philadelphia. Scale forms gradually in kettles and coffee machines over months, the dishwasher benefits from rinse aid to prevent glassware spotting, and bathroom fixtures develop calcium rings over time. Quarterly descaling of heating appliances is the standard maintenance schedule. The PFAS level of 7.9 ppt warrants use of a certified drinking water filter — Philadelphia's river supply draws from watersheds with known PFAS sources in the southeast Pennsylvania manufacturing corridor.
