Strathcona Water Hardness & Quality Report (2026)

Strathcona County Utilities supplies water to more than 100,000 residents in Sherwood Park and surrounding areas east of Edmonton, Alberta. The utility draws from the North Saskatchewan River and local groundwater aquifers. Treated water comes from the Ross Creek Water Treatment Plant and the Poppy Wind Lake Water Treatment Plant, with additional supply from wells. The Strathcona County watershed stretches across 1183 km² and its headwaters originate in the Rocky Mountains, with the North Saskatchewan River basin flowing into the central plains.

Geologically, the area features the Edmonton Formation, a Tertiary bedrock unit composed of sandstones, shales, and siltstones. This formation sits atop the Cretaceous Mannville Group. Glacial till and outwash deposits help recharge local aquifers. Within the sedimentary layers, lenses of limestone and dolomite weather, releasing calcium and magnesium ions. This mineral content contributes to a moderately mineralised groundwater supply. Surface waters tend to be softer due to less contact with these mineral-rich rocks.

When water reaches this moderately hard level, you might notice scale buildup affecting appliances like water heaters, dishwashers, and washing machines. This can reduce their efficiency by 20-30% over time, leading to higher energy costs. Faucet aerators and showerheads can also become clogged, potentially causing spotty dishes or a less satisfying shower. To manage this, regular descaling with vinegar, installing low-flow fixtures, and flushing your water heater annually can help. For persistent issues like soap scum or stiff laundry, a water softener is often recommended.
