Uxbridge Water Hardness & Quality Report (2026)

The Uxbridge DPW Water Division provides drinking water to the residents of Uxbridge, Massachusetts, drawing its supply from local groundwater aquifers. The Uxbridge water system, located at 80 River Road, Uxbridge, MA 01569, utilizes groundwater wells that tap into the town's aquifer system. This groundwater originates within the New England Upland physiographic province, where the underlying geology is characterized by Precambrian metamorphic bedrock, mainly gneiss and schist, covered by Quaternary glacial deposits like till, sand, and gravel. As water filters through these geological layers, it dissolves minerals, notably calcium and magnesium, which contribute to the supply's moderate mineralization.

The water's journey through the New England Upland's Precambrian metamorphic bedrock, specifically gneiss and schist, along with overlying Quaternary glacial deposits, dictates its mineral content. As groundwater percolates through these formations, it picks up dissolved minerals. This process, typical of crystalline aquifer systems in New England, leads to the water having moderate levels of hardness due to the dissolution of calcium and magnesium.

With its moderately hard water, Uxbridge residents might notice gradual mineral buildup in fixtures, pipes, and water heaters over time. You may also find that soaps and detergents aren't as effective, and appliances like dishwashers and washing machines could operate less efficiently. To combat scale, periodically descaling hot water tanks is a good idea. Using rinse aids in your dishwasher and laundry additives can also help. While most households won't need a water softener for everyday use, installing one could extend appliance life and improve cleaning. It's also worth noting that the groundwater supply has reportedly contained trace organic compounds; for current compliance and treatment specifics, consulting the town's annual water quality report is recommended.
