What Makes Springfield's Water Unique?
Local geology and source profile
Springfield, Virginia, in Fairfax County — a major northern Virginia Washington DC suburban community (Springfield is a significant Fairfax County unincorporated community — one of the most strategically located northern Virginia communities, situated at the intersection of I-95, I-395, and I-495 (the Capital Beltway); the Springfield Interchange (known locally as the 'Mixing Bowl') is one of the most complex and heavily-trafficked highway interchanges in the United States, connecting the major Washington DC area interstates), home of significant shopping (Springfield Town Center is one of the major regional malls in northern Virginia), home of the National Geospatial-Intelligence Agency (the NGA headquarters campus is in Springfield — one of the most important US intelligence agencies responsible for satellite imagery and geospatial intelligence), a diverse Fairfax County community with a significant federal government contractor, military, and diverse immigrant population, and a major northern Virginia transit hub — draws its municipal water supply via Fairfax Water. Water hardness in Springfield measures 139 mg/L — classified as moderately hard.
Springfield's moderate hardness reflects the northern Virginia Fairfax Water Occoquan Reservoir supply characteristics. The Fairfax Water distributes Occoquan Reservoir and Potomac River supply through the Springfield zone with effective treatment, producing the moderate 139 mg/L.
At 139 mg/L, Springfield residents encounter moderate scale accumulation. Monthly cleaning is recommended. Fairfax Water consistently delivers water meeting all Virginia DEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Potomac River (Occoquan Reservoir) via the Fairfax Water — the Fairfax County northern Virginia Springfield corridor (Precambrian calcareous-poor Piedmont gneiss — the calcareous-moderate northern Virginia Fairfax Water Occoquan supply; Fairfax Water effective treatment to Springfield zone); moderately hard supply at 139 mg/L in Fairfax County.
