What Makes Stony Plain's Water Unique?

Local geology and source profile

Source: RiverTDS: 274 mg/LpH: 7.8

The Town of Stony Plain water utility supplies residents in Stony Plain, Alberta, and surrounding areas of Parkland County. This mixed supply relies on both surface water from the North Saskatchewan River watershed and groundwater drawn from local aquifers. Water undergoes treatment at a primary facility before distribution to the community.

The region's geology features Cretaceous-age sedimentary formations, including significant layers of limestone and dolomite. These carbonate-rich rocks, common in central Alberta's geological landscape, are highly soluble. As precipitation filters through these formations into the underlying aquifer system, it picks up substantial amounts of calcium and magnesium, resulting in a naturally hard water supply.

Homeowners in Stony Plain may notice the effects of this hard water, such as scale buildup on faucets and inside kettles, and a diminished lather from soaps and detergents. Appliances like dishwashers and water heaters can also suffer reduced efficiency and a shorter lifespan due to mineral deposits. Installing a water softener is often recommended to counteract these issues. Regularly descaling fixtures and maintaining appliances can help manage the accumulation of mineral deposits.
