Know your Water

Any Chicago resident may call 311 to request a free water quality test kit

If you are concerned about the potential of elevated lead levels in your home's water, you may wish to have your water tested.

The test kit consists of three bottles, a mailing box, and instructions. Follow the instructions included in your kit for collecting water samples in your home, put the bottles in the shipping box and place it in a location (such as the entryway or front door) for pick up by Department of Water Management (DWM) staff.

If you would prefer to schedule a time for a DWM representative to come to your home to take water samples, keep in mind that this appointment must be scheduled for a time when you are home and you have not used your water for over 6 hours. Please call 311 or fill out the form below and a representative will reach out to you to schedule a visit.
