Mounds View Water Hardness & Quality Report (2026)

Mounds View Municipal Water Company supplies water to roughly 12,959 residents in Mounds View, Ramsey County, Minnesota. Their entire water supply comes from groundwater wells, with treatment happening at facilities managed from City Hall at 2401 Mounds View Boulevard. The utility doesn't use any surface water sources like reservoirs or rivers; all water is drawn from local aquifers. This groundwater originates within the Mississippi River Basin, specifically from sub-basins within the Anoka Sand Plain physiographic province.

The region's geology consists of glacial deposits from the Wisconsinan glaciation lying atop fractured bedrock. These bedrock aquifers include the Jordan Aquifer, which is Cambrian sandstone, and the dolomitic limestones of the Prairie du Chien Group situated above it. Because the water spends a long time interacting with these carbonate minerals, it picks up significant amounts of calcium and magnesium, giving it a hard quality. This is typical for karst-influenced systems in central Minnesota, where dissolving limestone formations greatly impacts the water's chemistry.

This hard water can lead to considerable scale buildup, posing a serious risk to appliances like water heaters, dishwashers, and washing machines. Such buildup not only reduces efficiency but also shortens the lifespan of your plumbing fixtures. Hot water appliances are particularly vulnerable, as minerals tend to precipitate out when heated. To combat this, homeowners should consider annual descaling of heaters, installing filters that inhibit scale, and regularly flushing their systems. A water softener is highly recommended to prevent appliance damage, extend their life, and improve how effectively soap lathers, while also preventing unsightly spots on dishes and fixtures.
