Overview
Northern Virginia's Fairfax Water and the Washington Aqueduct deliver top-tier Potomac and Occoquan supply; Virginia Beach and Norfolk manage sophisticated reservoir networks. Richmond's 2025 treatment-plant failure, which left the capital region under a days-long boil advisory, exposed how much rides on aging plants even in compliant systems.
Occoquan's system is a national landmark in planned water reuse (highly treated wastewater sustains the reservoir), coalfield counties in the southwest wrestle with failing small systems and mining-legacy wells, and kepone's long shadow still keeps James River fish advisories alive without affecting treated drinking water.
Common Contaminants in Virginia
Richmond and older Tidewater housing carry legacy lines; utilities run corrosion control and replacement
Warm reservoir systems manage seasonal THMs; small southwest systems record most exceedances
Detections near defense installations (Oceana, Langley area) and scattered industrial sites; treatment planning proceeds under federal limits
Violations & Compliance
The large systems comply consistently; Richmond's 2025 outage was an infrastructure failure rather than a standards violation and accelerated state scrutiny of plant resilience. Coalfield small systems remain the chronic weak point.
Water Hardness in Virginia
Moderate, typically 50–120 mg/L. Reservoir- and river-fed systems in northern Virginia and Hampton Roads are soft to moderate; Shenandoah Valley limestone groundwater is hard.
Hardness affects taste, limescale, and soap — not safety. Compare levels across all cities or read the water hardness guide.
