Posen's current Village Consumer Confidence Report identifies Lake Michigan surface water as the municipal source. Windy City Water Pros can help you consider a whole-home water-treatment setup for your Posen home after discussing your goals and evaluating the installation. 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.

What Posen's report lists

This report does not publish a hardness figure. Ask us to test your water instead of using a guessed number.
This Consumer Confidence Report describes the municipal water system and reported sampling or program information. It does not determine water conditions at an individual home, which can be affected by building plumbing, service-line material, fixtures, and local conditions.
