What Makes Cherry Hill's Water Unique?
Local geology and source profile
Cherry Hill, Virginia, in Prince William County — an unincorporated Prince William County community adjacent to Dumfries and Lake Ridge in outer Northern Virginia — receives its municipal water from the Prince William County Service Authority (PWCSA), drawing from Occoquan Reservoir through the PWCSA water treatment plant — the same Occoquan supply system serving Buckhall (196 mg/L) and Sudley (187.5 mg/L) in Prince William County.
The hard 193 mg/L hardness and elevated TDS of 507.1 mg/L reflect the Occoquan watershed's calcareous Piedmont-Triassic character — dramatically harder than the Fairfax Water Potomac-supplied Northern Virginia communities (Vienna: 85.5 mg/L). Cherry Hill falls mid-range within the PWCSA service zone (between Sudley's 187.5 mg/L and Buckhall's 196 mg/L), consistent with the Occoquan Reservoir receiving varied Piedmont tributary inputs. The Occoquan watershed drains Triassic Newark Basin calcareous shale and Cambrian Catoctin Formation (calcareous) producing the hard Prince William supply.
At 193 mg/L, Cherry Hill's water is hard — scale builds steadily in kettles and appliances, dishwashers benefit from rinse aid, and water heaters should be descaled annually. Monthly descaling is recommended. The PFAS level of 10.1 ppt warrants a certified reverse osmosis drinking water filter — Quantico Marine Corps Base (Prince William County — AFFF) and the Washington DC metro PFAS complex contribute to Cherry Hill's elevated readings.
Geology & Source: Cherry Hill in Prince William County draws from the Prince William County Service Authority on Occoquan Reservoir (Prince William County, north Virginia) — the Occoquan drains the Virginia Piedmont (Triassic Newark Basin calcareous, Cambrian Catoctin Limestone) — Virginia Prince William County Occoquan Piedmont-Triassic watershed produces hard water at 193 mg/L with TDS 507.1 mg/L in this Prince William County Virginia community.
