Water Testing

If you have municipal or "city" water, please contact your municipal water provider first if you have questions, concerns or problems with your water.

Please call the Environmental Health Division at (734) 222-3800 before sampling your water. You will need to obtain a special sampling bottle from the Western Service Center, located at 705 N. Zeeb Road in Ann Arbor (Map). 

Western Service Center staff will instruct you on proper sampling procedures. Once the sample has been taken, return the bottle to the Western Service Center. Keep in mind that turn-around-times for test results vary.

Available Water Quality Tests and Fees 

Other tests may be available at the Environmental Health Division, so please call for more information. Note: There is a fee of $59 per sample, in addition to the fee listed, if the sample is collected by Environmental Health personnel.

The Michigan Department of Environmental Quality Laboratory also offers testing services and resources, including a list of certified laboratories who may offer additional testing services not provided by Washtenaw County.
