Lisle’s current Village report identifies Lake Michigan as the municipal drinking-water source. Use that report as local system context—not as a test of the water or plumbing at one Lisle home. 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.
