What Makes Southwest Center City Philadelphia's Water Unique?
Local geology and source profile
Southwest Center City Philadelphia, Pennsylvania, in Philadelphia County — a Philadelphia County neighborhood adjacent to Center City and Point Breeze in south-central Philadelphia — receives its water from the Philadelphia Water Department, drawing from the Delaware River through the southeast Pennsylvania distribution.
The soft 86 mg/L hardness and TDS of 129.9 mg/L reflect the Philadelphia County Delaware River supply's softer character — the Precambrian Highlands Gneiss is highly insoluble, and Triassic Newark Formation basalt and sandstone contribute only modest dissolved minerals to the Delaware watershed in the Philadelphia metro area (compare Center City PA: 84/125 in Philadelphia County comparable; Point Breeze PA: 87/133 in Philadelphia County comparable; Southwest Center City consistent soft from the same Philadelphia County Delaware River Precambrian insoluble supply). The Delaware watershed at Philadelphia — Precambrian Highlands Gneiss (insoluble — primary dilutant), Triassic Newark Formation (slightly calcareous — primary hardness contributor), and Quaternary Delaware alluvium (slightly calcareous — minor TDS).
At 86 mg/L with TDS 130, Southwest Center City Philadelphia's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 4.3 ppt is moderate — a certified drinking water filter provides added protection. Review the Philadelphia Water Department's annual water quality report.
Geology & Source: Southwest Center City Philadelphia in Philadelphia County draws from Philadelphia Water on the Delaware River (Philadelphia County, southeast Pennsylvania) — the Delaware watershed at Philadelphia drains Precambrian Highlands Gneiss (insoluble) and Triassic Newark Formation (slightly calcareous) — Pennsylvania Philadelphia County Delaware River Precambrian insoluble supply produces soft water at 86 mg/L with TDS 129.9 mg/L.
