Justice Water Hardness & Quality Report (2026)

The Justice-Willow Springs Water Commission supplies water to roughly 18,406 residents across Justice and Willow Springs, Illinois. This utility purchases treated surface water, mainly from Lake Michigan, which is delivered by regional suppliers such as Illinois American Water. The water reaches homes without any local softening treatment. The system's service area is situated at 7000 S. Archer Road, Justice, IL 60458. Originating from the Lake Michigan watershed and influenced by the Des Plaines River sub-basin, the water undergoes standard surface water treatment processes including coagulation, sedimentation, filtration, and disinfection, likely with chlorine.

The geology beneath Justice features glacial deposits covering Paleozoic bedrock, notably Silurian-age dolomite and limestone. These carbonate-rich rocks readily dissolve minerals as water moves through them, contributing significantly to the water's hard character. Aquifers within the shallow glacial till and outwash also play a role, enriching the supply with minerals characteristic of northern Illinois and the Great Lakes basin.

Homeowners may notice scale buildup affecting the efficiency and lifespan of appliances like water heaters, dishwashers, and washing machines. Reduced water flow and visible white deposits on fixtures like faucet aerators and showerheads are common consequences. To combat these issues and protect plumbing, regular cleaning with vinegar, the installation of scale inhibitors, or the use of a water softener are practical solutions. Fortunately, the Justice water system consistently meets EPA standards for lead and copper, with no reported PFAS violations.
