What Makes Wyomissing's Water Unique?
Local geology and source profile
Wyomissing, Pennsylvania, in Berks County — a Berks County borough adjacent to Reading and West Reading in the Schuylkill River valley — receives its water from Pennsylvania American Water, drawing from the Schuylkill River through the east-central Pennsylvania distribution.
The hard 133 mg/L hardness and TDS of 256.5 mg/L reflect the Berks County supply's hard Great Valley character — the Ordovician Annville Formation and Cambrian Elbrook Formation are calcareous-dolomitic formations in the Pennsylvania Great Valley limestone corridor, and the Schuylkill River acquires moderate dissolved mineral content from its Berks County limestone drainage (compare Reading PA: 129/247 in Berks County comparable; West Reading PA: 136/265 in Berks County comparable; Wyomissing consistent hard from the same Berks County Schuylkill River Ordovician calcareous supply). The Schuylkill watershed at Reading — Ordovician Annville Formation (calcareous — primary hardness contributor), Cambrian Elbrook Formation (dolomitic calcareous — secondary contributor), and Quaternary Schuylkill River alluvium (calcareous — minor TDS).
At 133 mg/L with TDS 257, Wyomissing's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 6.8 ppt warrants a certified drinking water filter. Review Pennsylvania American Water's annual water quality report.
Geology & Source: Wyomissing in Berks County draws from the Pennsylvania American Water on the Schuylkill River supply (Berks County, east-central Pennsylvania) — the Schuylkill watershed at Reading draws from Ordovician Annville Formation (calcareous) and Cambrian Elbrook Formation (dolomitic calcareous) — Pennsylvania Berks County Schuylkill River Ordovician calcareous supply produces hard water at 133 mg/L with TDS 256.5 mg/L.
