Rogers Water Hardness & Quality Report (2026)

Rogers, Minnesota's drinking water comes from groundwater, drawn from the Twin Cities aquifer system. This vital resource is treated at the city's water treatment facilities before being delivered to homes and businesses throughout Rogers and nearby communities in Hennepin County. The Twin Cities aquifer, a vast underground network of Ordovician and Cambrian-age sandstones, dolomites, and limestones, is the primary source for the region's water supply. This geological makeup is typical for south-central Minnesota, where the subsurface is characterized by extensive carbonate bedrock.

The Ordovician and Cambrian layers, particularly the dolomite and limestone, are rich in dissolved calcium and magnesium. As groundwater naturally flows through these rock formations, these minerals are leached into the water, giving Rogers its characteristic hard water. This geology is common in the Twin Cities aquifer system, influencing the water quality delivered to Minnesota residents in this region.

This very hard water means you'll likely notice scale buildup in appliances like water heaters and kettles, and it can reduce the effectiveness of soaps and detergents. You might also see mineral deposits on fixtures and glassware. Appliances such as dishwashers and washing machines can suffer from reduced efficiency and mineral accumulation over time. Installing a water softener is highly recommended to combat these issues, lower maintenance costs, and help your appliances last longer. You'll want to regularly descale your water-using equipment for peak performance. The water also contains iron, typically between 1.3 and 1.6 milligrams per liter, as reported in the city's 2023 Drinking Water Report.
