What Makes Danville's Water Unique?
Local geology and source profile
Danville, Virginia, on the North Carolina border — the 'Last Capital of the Confederacy' (Confederate President Jefferson Davis's final government was headquartered at the Sutherlin Mansion in Danville in April 1865), a historic tobacco market and textile manufacturing city, a diverse community rebuilding from the decline of Dan River Mills (one of the world's largest denim producers, closed 2006), and a Virginia gateway to the Piedmont Triad — draws its municipal water supply from the Dan River via the City of Danville Utilities. Water hardness in Danville measures 95.5 mg/L — classified as moderately soft.
Danville's moderate softness reflects the Dan River's calcareous-moderate Piedmont Virginia geology. The Dan River drains: the Blue Ridge (Precambrian Catoctin Formation metavolcanic greenstone — calcareous-poor volcanic terrain); the Dan River Triassic Basin (Triassic Dan River Formation calcareous-moderate red arkose — a Newark-type Triassic rift basin in south-central Virginia, moderately calcareous); and the Piedmont Province (Precambrian–Paleozoic calcareous-poor crystalline rocks — the Virginia Piedmont metamorphic terrain). The City of Danville's treatment produces the moderate 95.5 mg/L.
With hardness at 95.5 mg/L, Danville residents enjoy moderately soft water. City of Danville Utilities consistently delivers water meeting all Virginia DEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Dan River (Danville Water Treatment Plant) via the City of Danville Utilities Water Division — the Pittsylvania County south-central Virginia Piedmont Dan River corridor (Triassic Dan River Basin calcareous-moderate arkose and Precambrian–Paleozoic Piedmont calcareous-moderate metamorphic terrain); moderately soft supply at 95.5 mg/L in Pittsylvania County.
