Broadlands Water Hardness & Quality Report (2026)

Loudoun Water provides treated drinking water to residents and businesses in Broadlands, Virginia, a community near Ashburn. The primary sources for this supply are the Potomac River and Goose Creek, which are part of the Central Water System. Water undergoes conventional treatment processes at facilities like the Trap Rock Water Treatment Plant. These steps include coagulation, sedimentation, filtration, and disinfection, all designed to meet the stringent Safe Drinking Water Act standards set by the Virginia Department of Health. Customers can find detailed compliance information in annual Consumer Confidence Reports, usually distributed via bill notices or by contacting Loudoun Water directly.

The water's journey begins in the Potomac River Basin watershed, traversing both the Blue Ridge and Piedmont physiographic provinces. Underlying these regions are geological formations like the Cambrian-Ordovician carbonate sequences and metamorphic complexes. Goose Creek draws from a sub-watershed characterized by granitic and schistose bedrock near the Great Falls area. The presence of limestone and dolomite layers from Paleozoic periods means these source rocks naturally dissolve minerals, particularly calcium carbonate, into the surface waters. This geological influence results in a moderately mineralized water supply, distinct from softer groundwater sources.

This moderately hard water can lead to scale buildup in household appliances such as dishwashers, washing machines, and water heaters, potentially reducing their efficiency and lifespan. You might also notice reduced soap lathering and spotting on glassware after washing. For homeowners experiencing these issues, such as soap scum or dry skin, a water softener is often recommended. These systems use ion exchange to reduce mineral content, though they don't remove all beneficial minerals. Loudoun Water also adds fluoride for dental health and orthophosphate to help prevent lead leaching from plumbing. Recent reports show levels for disinfection byproducts, nitrates, radium, and PFAS well within EPA limits, with no recent lead or copper violations noted.
