What Makes Countryside's Water Unique?
Local geology and source profile
Countryside, Virginia, in Loudoun County — a Loudoun County community adjacent to Sterling and Ashburn in the north Virginia DC suburbs — receives its water from Loudoun Water, drawing from the Potomac River through the north Virginia distribution.
The hard 169 mg/L hardness and TDS of 404.9 mg/L reflect the Loudoun County supply's hard upper Potomac character — the Cambrian Tomstown Formation contributes calcareous mineral content from the Shenandoah Valley limestone corridor, while the Precambrian Blue Ridge Basement provides insoluble dilution; Loudoun Water's Potomac River supply at the north Virginia suburban distribution concentrates higher hardness than the DC downstream supply (compare Sterling VA: 165/394 in Loudoun County comparable; Ashburn VA: 172/415 in Loudoun County comparable; Countryside consistent hard from the same Loudoun County Potomac River Cambrian calcareous supply). The Potomac River at Loudoun County — Cambrian Tomstown Formation (calcareous — primary hardness contributor), Precambrian Blue Ridge Basement (insoluble — primary dilutant), and Quaternary Potomac River alluvium (calcareous — TDS contributor).
At 169 mg/L with TDS 405, Countryside's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 8.8 ppt warrants a certified drinking water filter. Review Loudoun Water's annual water quality report.
Geology & Source: Countryside in Loudoun County draws from the Loudoun Water on the Potomac River supply (Loudoun County, north Virginia) — the Virginia Piedmont at Loudoun County draws from Cambrian Tomstown Formation (calcareous) and Precambrian Blue Ridge Basement (insoluble) — Virginia Loudoun County Potomac River Cambrian calcareous supply produces hard water at 169 mg/L with TDS 404.9 mg/L.
