Drinking 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.

Water Quality Tests

Find information about available water quality tests and fees (PDF).

To test your water, you will need to get a special sampling bottle from the our Environmental Health Division office, located at: 

Washtenaw County Western Service Center
705 N Zeeb Road
Ann Arbor, MI 48103

Proper Sampling Procedures

Environmental Health staff will instruct you on proper sampling procedures. Once the sample has been taken, you must return the bottle to the Western Service Center before 3:00pm, Monday-Friday. Keep in mind that turn-around-times for test results vary.

More Information

Note: There is a fee of $61 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.
