Water Softener and Filtration in Long Grove, IL
Long Grove’s 2025 Village report says municipal water comes from two active deep groundwater wells at the treatment plant. The report says the Village filters and ion-exchange softens that water before it enters distribution. We help Long Grove homeowners consider their own plumbing, water goals, and installation before choosing a whole-home setup. A utility report describes the public system. It is not a reading from one home's tap, where plumbing, fixtures, sample location, and existing treatment can change the experience.

Local Questions
Long Grove water treatment FAQs
Town FAQ source: Annual Drinking Water Quality Report 2025 (2025)
Where does Long Grove’s municipal water come from?
Long Grove’s 2025 Annual Drinking Water Quality Report says the source is groundwater from two active deep wells—Well 1 (02084) and Well 2 (02085)—located at the treatment plant. This municipal source information is useful context, but conditions at a particular home can still be affected by that home’s plumbing and fixtures.
How does the Village treat Long Grove water?
The Village’s 2025 report says the water is treated through filtration and ion-exchange softening. It says sodium hypochlorite is added for disinfection before water enters the ground-storage reservoir. That municipal process does not by itself determine the right equipment for an individual home.
What does the latest Long Grove report say about lead monitoring?
The 2025 lead-and-copper table lists a lead 90th percentile of 2 ppb, zero sites over the 15 ppb action level, and no lead violation. Those are system sampling results; they are not proof of conditions at every Long Grove tap.
Can the Village report tell me what is happening at my Long Grove faucet?
Not by itself. The report describes Long Grove’s public water system and its reported monitoring. Plumbing, service-line materials, fixtures, existing treatment equipment, and sample location can affect water at an individual home.
