The Village of Mount Prospect is dedicated to providing you with an adequate and dependable supply of safe drinking water. As part of this effort, we have prepared this Consumer Confidence Report (CCR). This report will provide residents and businesses served by the Village-owned water distribution system with the information necessary to make prudent decisions about how they use tap water. Please note, information in this CCR does not pertain to Illinois American Water Company water customers. Illinois American Water Company will prepare and distribute a separate CCR for their water customers and they can be reached at 1-800-422-2782.

This report is a requirement of the 1996 Safe Drinking Water Act amendments. It summarizes where your water came from, what it was made of, and how it compared to the standards established by regulatory agencies. Information about water consumed during the reporting year will be made available in a CCR scheduled for distribution during the following year. CCRs will be published in July of each year.

Information in this report describes water consumed during the 2025 calendar year.
