The Village of Union's current 2025 Annual Drinking Water Quality Report identifies the community water system as Ground Water and lists Well 4 as an active groundwater source. Windy City Water Pros helps homeowners explore whole-home water treatment options after discussing their goals, plumbing, and installation space. 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.
