What Is in Farmington Water
Water in Farmington measures 16 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 very hard water, significantly above the threshold where mineral damage begins occurring in home plumbing systems. 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.
Farmington water tests at 16 grains per gallon. The city is one of the fastest-growing in Dakota County, and new construction homeowners frequently install water softeners as part of the build-out.
While there are no active PFAS advisories for this municipal supply, standard municipal treatment does not remove chlorine, chloramines, or trace pharmaceuticals.
Why a Water Softener Matters in Farmington
At 16 grains per gallon, Farmington water deposits roughly 7 to 10 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 Farmington homes see soap usage drop by 30 to 50 percent, longer appliance lifespan, and noticeably softer skin and hair after install.
Because Farmington water measures 16 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.

A water softener handles hardness. It does not handle chlorine, chloramines, PFAS, lead from aging pipes, pharmaceuticals, or other contaminants. For most Farmington homes, the right system is a softener paired with targeted filtration.
