What Makes Huntington's Water Unique?
Local geology and source profile
Huntington, Virginia, in Fairfax County — a Fairfax County unincorporated community adjacent to Alexandria and Groveton in the south Fairfax County suburbs — receives its water from Fairfax Water, drawing from Occoquan Reservoir and the Potomac River through the north Virginia distribution.
The soft 87.5 mg/L hardness and TDS of 139.3 mg/L reflect the Fairfax County Occoquan supply's soft character — the Precambrian Blue Ridge Gneiss is highly insoluble, and Triassic Manassas Sandstone contributes only modest dissolved minerals to the Bull Run-Occoquan watershed (compare Alexandria VA: 85/133 in Fairfax/Alexandria comparable; Groveton VA: 89/145 in Fairfax County comparable; Huntington consistent soft from the same Fairfax County Occoquan Reservoir Precambrian insoluble supply). The Occoquan watershed — Precambrian Blue Ridge Gneiss (insoluble — primary dilutant), Triassic Manassas Sandstone (slightly calcareous — primary hardness contributor), and Quaternary Occoquan alluvium (slightly calcareous — minor TDS).
At 87.5 mg/L with TDS 139, Huntington's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 4.4 ppt is moderate — a certified drinking water filter provides added protection. Review Fairfax Water's annual water quality report.
