Water Quality Report

Lead Service Line Inventory

In compliance with Section 17.12 of the Illinois Environmental Protection Act (415 ILCS 5/17.12) requires Community Water Supplies to identify and report all water service supply line material within their system by April 15, 2024 with the goal of locating any potential lead water service lines. This is the City's updated water service line material inventory as of April 15, 2023. In the coming year Public Works employees along with our contractor will be working diligently to identify the remaining unknown service with the use of online surveys, mailings and in person inspections.  If you have any questions of concerns, please call 847-963-0500 Ext. 7022.
