What Makes Yeadon's Water Unique?
Local geology and source profile
Yeadon, Pennsylvania, in Delaware County — a Delaware County borough adjacent to Darby and Lansdowne in the inner Philadelphia suburbs — receives its water from Aqua Pennsylvania or Philadelphia Water, drawing from the Delaware River and Schuylkill River through the southeast Pennsylvania distribution.
The hard 142 mg/L hardness and TDS of 284.3 mg/L reflect the Delaware County Delaware-Schuylkill supply's hard character — the Precambrian Highlands Gneiss provides insoluble dilution, but Triassic Newark Formation red sandstone and limestone contribute dissolved minerals from the inner Philadelphia suburban zone (compare Darby PA: 139/278 in Delaware County comparable; Lansdowne PA: 145/290 in Delaware County comparable; Yeadon consistent hard from the same Delaware County Delaware River Precambrian-Triassic supply). The Delaware-Schuylkill watershed at Delaware County — Precambrian Highlands Gneiss (insoluble — dilutant), Triassic Newark Formation (slightly calcareous — primary hardness contributor), and Quaternary Delaware alluvium (calcareous — TDS contributor).
At 142 mg/L with TDS 284, Yeadon's water is hard — scale builds in appliances and fixtures. Quarterly descaling is appropriate. The PFAS level of 7.2 ppt warrants a certified drinking water filter — the Delaware County inner Philadelphia suburbs industrial legacy contributes to Yeadon's elevated PFAS readings. Review Aqua Pennsylvania's annual water quality report.
Geology & Source: Yeadon in Delaware County draws from the Aqua Pennsylvania on the Delaware River (Delaware County, southeast Pennsylvania) — the Delaware watershed at Delaware County drains Precambrian Highlands Gneiss (insoluble) and Triassic Newark Formation (slightly calcareous) — Pennsylvania Delaware County Delaware River Precambrian-Triassic supply produces hard water at 142 mg/L with TDS 284.3 mg/L.
