What Makes Linton Hall's Water Unique?
Local geology and source profile
Linton Hall, Virginia, an unincorporated community in Prince William County — a major north Prince William County DC exurban community (Linton Hall is in the rapidly growing Gainesville–Bristow corridor of Prince William County — one of the fastest-growing suburban areas in the greater Washington DC metro area), adjacent to the Innovation Technology Park corridor in the Prince William–Loudoun tech and data center hub, a diverse Prince William County community with a significant Indian-American, Korean-American, and Latino-American population, and part of one of the largest data center concentrations in the world (Prince William County — the 'Data Center Alley' — hosts the largest concentration of data centers globally) — draws its municipal water supply from the Occoquan Reservoir via the Prince William County Service Authority. Water hardness in Linton Hall measures 167.5 mg/L — classified as hard.
Linton Hall's hard supply reflects the north Prince William County Occoquan Reservoir watershed's calcareous-moderate Piedmont geology and PWCSA distribution characteristics. The Occoquan Reservoir (Bull Run watershed) drains the Northern Virginia Piedmont (Precambrian–Paleozoic calcareous-moderate Bull Run Mountains crystalline gneiss and schist — the north Virginia Piedmont crystalline belt; Triassic Culpeper Basin calcareous-moderate red sediment). PWCSA distributes to the north Prince William County Linton Hall zone, producing the hard 167.5 mg/L.
At 167.5 mg/L, Linton Hall residents face regular hard water challenges. Monthly descaling with citric acid solution is recommended. PWCSA consistently delivers water meeting all Virginia DEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Occoquan Reservoir (Bull Run watershed) via the Prince William County Service Authority (PWCSA) — the Prince William County north Virginia DC exurban corridor (Precambrian–Paleozoic calcareous-moderate Virginia Piedmont gneiss and the Occoquan watershed Bull Run calcareous-moderate crystalline supply; PWCSA north Prince William distribution); hard supply at 167.5 mg/L in Prince William County.
