What Makes Uxbridge's Water Unique?
Local geology and source profile
The Uxbridge Drinking Water System, operated by Durham Region, supplies water to residents in Uxbridge, Ontario. Its supply comes from a mix of sources, including surface water drawn from Lake Ontario through regional connections, and local groundwater wells. Water undergoes treatment at conventional municipal facilities before distribution throughout the Uxbridge service area within Durham County. This system is part of the larger Greater Toronto Area water network.
Geologically, Uxbridge sits atop Paleozoic limestone and dolomite bedrock, a common characteristic of southwestern Ontario and the Greater Toronto Area. As rainwater filters through the soil and these mineral-rich rock layers, it picks up dissolved calcium and magnesium. This natural geological process is the main reason why the water supply for Uxbridge is classified as very hard.
Homeowners in Uxbridge will likely notice significant scale buildup on appliances like kettles, dishwashers, washing machines, and hot water heaters due to the water's hardness. Limescale can also form on plumbing fixtures and inside pipes, potentially reducing their lifespan and efficiency. Installing a water softener is highly recommended to mitigate these issues, protect household appliances, and improve how effectively soaps and detergents work. For those without a softener, regularly descaling fixtures with vinegar or other cleaning agents is a good practice.
Geology & Source: Paleozoic limestone and dolomite bedrock; these formations naturally dissolve calcium and magnesium, producing very hard water
