Apple Valley draws its municipal water from the Prairie du Chien-Jordan aquifer, where hardness levels average 17 to 18 grains per gallon. That mineral load coats fixtures, clogs valves, and wears out water heaters faster than normal. Many homeowners notice cloudy glassware, stiff laundry, and scale on heating elements long before realising the source is their water.
At Peterson Salt, we have served the Twin Cities for decades, helping families and businesses across the city manage those same conditions. We install and maintain professional-grade softeners, filtration systems and deliver high-purity salts backed by accurate local testing. Our recommendations come from real water data and years of field experience with Minnesota’s unique aquifers.
