Vernon Hills Water Company

The Vernon Hills Public Water System is dedicated to providing safe, clean water to all residents. We strongly uphold the principles of the Safe Drinking Water Act, which requires every water utility to publish an annual Consumer Confidence Report (CCR). This report details our water sources, treatment processes, and comprehensive chemical analysis results.

If you would like a physical copy of the water report, please contact our office. For any questions about your Water Quality Report, feel free to reach out to our water quality specialist at 847-377-7500 anytime.

1. Where does Vernon Hills water come from?
   Vernon Hills supplies purchased surface water to Vernon Hills, Illinois.
2. Does Vernon Hills test its tap water?
   Yes. Like every public water system, Vernon Hills must test its water under the federal Safe Drinking Water Act and publish an annual water quality report (Consumer Confidence Report). Ask the utility for the latest report or look for it on its website.
3. How do I contact Vernon Hills?
   Call 847-367-3700 or visit 290 Evergreen Drive, Vernon Hills, IL 60061, or use the contact options on the utility’s website.
4. Does Vernon Hills water contain lead?
   Water usually leaves the treatment plant without lead. Lead can enter tap water from older service lines, solder and brass fixtures inside homes, especially when water sits in the pipes. Run the tap before drinking if water has been sitting, and ask the utility about lead testing and service line records.
5. Is Vernon Hills water hard?
   Hardness depends on the source and changes over time. The annual water quality report lists hardness, or you can test it at home. If it is above about 7 grains per gallon, a water softener sized to your measured hardness will stop scale and spotting.
