What Is in St. Louis Park Water
Water in St. Louis Park measures 18 to 19 grains per gallon, which is classified as very hard on the standard hardness scale. The city draws from Prairie du Chien and Jordan sandstone aquifers via its municipal well system. Want to check other nearby areas? View our Twin Cities Water Quality Map.
This is extremely hard water, placing it among the highest mineral content levels in the metro area. Hardness at this level causes scale buildup on fixtures, reduced soap and detergent efficiency, dry skin and hair after bathing, spotting on dishes and glassware, and shortened lifespan on water-using appliances including water heaters, dishwashers, and washing machines.
St. Louis Park municipal water tests at 18 to 19 grains per gallon. The west side of the city has documented historic groundwater contamination (Reilly Tar site) which has been remediated but remains a reason to invest in reverse osmosis drinking water filtration.
Note regarding contamination: Historic contamination concern in west side neighborhoods. A reverse osmosis system is strongly recommended for drinking and cooking water in affected homes.
Why a Water Softener Matters in St. Louis Park
At 18.5 grains per gallon, St. Louis Park water deposits roughly 10 to 15 pounds of scale per year inside a typical household water heater and plumbing system. Over five years, that scale measurably reduces water heater efficiency, can void manufacturer warranties on tankless water heaters, and shortens the working life of dishwashers, washing machines, faucets, and shower fixtures.
A properly sized whole-home water softener removes the calcium and magnesium ions that cause scale, protects every water-using appliance in your home, and dramatically improves daily water quality. Most St. Louis Park homes see soap usage drop by 30 to 50 percent, longer appliance lifespan, and noticeably softer skin and hair after install.
Because St. Louis Park water measures 18 to 19 grains per gallon, standard off-the-shelf softeners often struggle to keep up or wear out prematurely. We install commercial-grade Clack systems sized specifically for your home's square footage and daily water usage.
