What Makes Baileys Crossroads's Water Unique?
Local geology and source profile
Baileys Crossroads, Virginia, in Fairfax County in the inner Northern Virginia corridor between Falls Church and Arlington — a dense, diverse commercial and residential community along the Columbia Pike corridor — receives its municipal water from Fairfax Water, the regional utility serving Fairfax County. Fairfax Water draws from Occoquan Reservoir (impounded on Bull Run in Prince William County) and the Potomac River via the Griffith Water Treatment Plant in Great Falls, blending and treating both sources for distribution throughout Fairfax County's service area.
The moderately soft 112 mg/L hardness and TDS of 205.5 mg/L reflect the Occoquan Reservoir's dominant contribution to Fairfax County's inner suburb supply. Occoquan Reservoir collects water from the Northern Virginia Piedmont — an ancient terrain of Precambrian Grenville-age metamorphic gneisses, Paleozoic metavolcanic rocks, and the Triassic Manassas Sandstone of the Culpeper Basin — terrains with low carbonate content. The result is a moderately soft supply in the inner Fairfax County service zone, where the Occoquan share is typically higher than in outer Fairfax communities that may receive more Potomac River blending.
At 112 mg/L, Baileys Crossroads' water is moderately soft — comfortable for everyday household use in this urban Northern Virginia community. Scale forms gradually in kettles and appliances over several months, soap lathers well, and the dishwasher produces clean results without special treatment. Semi-annual descaling of heating appliances is adequate. The PFAS level of 5.7 ppt is moderate for inner Northern Virginia — Baileys Crossroads' proximity to Arlington's defense installations and the dense Crystal City/Tysons technology corridor contributes to the regional PFAS background.
Geology & Source: Baileys Crossroads in Fairfax County is served by Fairfax Water drawing from Occoquan Reservoir on the Bull Run watershed and supplementary Potomac River supply — Occoquan's watershed drains the Virginia Piedmont Province over Precambrian metamorphic rocks — Piedmont reservoir drainage combined with seasonal Potomac supply produces moderately soft water at 112 mg/L.
