What Makes Logan Square's Water Unique?
Local geology and source profile
Logan Square, Pennsylvania, in Philadelphia County — a Philadelphia County neighborhood adjacent to Fairmount and Spring Garden in northwest Center City Philadelphia — receives its water from the Philadelphia Water Department, drawing from the Schuylkill River through the southeast Pennsylvania distribution.
The hard 202.5 mg/L hardness and TDS of 513 mg/L are notable for Philadelphia — the Cambrian Chickies Formation and Triassic Newark Formation contribute significant calcareous mineral content to the Schuylkill watershed, and the Logan Square distribution zone may reflect localized treatment differences or elevated hardness aquifer blending (compare Fairmount PA: 198/503 in Philadelphia County comparable; Spring Garden PA: 206/523 in Philadelphia County comparable; Logan Square consistent hard from the same Philadelphia County Schuylkill River Cambrian calcareous supply). The Schuylkill watershed at Philadelphia — Cambrian Chickies Formation (calcareous — primary hardness contributor), Triassic Newark Formation (slightly calcareous — secondary contributor), and Quaternary Schuylkill alluvium (calcareous — TDS contributor).
At 202.5 mg/L with TDS 513, Logan Square's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 10.4 ppt is very high — a certified filter with PFAS removal is strongly recommended — the Philadelphia County Schuylkill River industrial and Superfund legacy contributes to Logan Square's very elevated PFAS readings.
Geology & Source: Logan Square in Philadelphia County draws from Philadelphia Water on the Schuylkill River (Philadelphia County, southeast Pennsylvania) — the Schuylkill at Philadelphia drains Cambrian Chickies Formation (calcareous) and Triassic Newark Formation (slightly calcareous) — Pennsylvania Philadelphia County Schuylkill River Cambrian calcareous supply produces hard water at 202.5 mg/L with TDS 513 mg/L.
