Mechanicsville Water Hardness & Quality Report (2026)

Henrico County Water serves Mechanicsville, Virginia, providing drinking water to approximately 292,000 people in Hanover County and surrounding areas including Henrico, Chesterfield, and other localities via wholesale contracts. The water originates from the James River and is treated at the Richmond Department of Public Utilities (DPU) Water Treatment Plant, originally built in 1924 on the river's banks. This facility has been significantly upgraded over the decades and can produce up to 132 million gallons per day to meet regional demand.

The James River watershed spans the Blue Ridge, Piedmont, and Coastal Plain physiographic provinces, draining diverse geology from granitic gneisses and schists to sedimentary basins. In the Piedmont section relevant to the intake, water interacts with fractured metamorphic rocks and minor limestone formations of Paleozoic and Mesozoic age, imparting a soft water character with limited mineral content. This surface water supply avoids the higher mineralization typical of groundwater from deeper carbonate aquifers.

As soft water, Mechanicsville's supply produces minimal scale buildup in pipes, fixtures, or appliances like water heaters and dishwashers. Soap lathers easily, reducing residue on skin, hair, and laundry without the need for extra detergent. No water softener is required or recommended, simplifying maintenance and avoiding associated costs. Two contaminants exceed EPA health guidelines (not legal limits), including bromodichloromethane; certified filters are advised for added protection. PFAS data indicates 4 contaminants above MCLGs per some analyses; treatment at the DPU plant involves coagulation, sedimentation, filtration, and disinfection.
