Water Quality Report
The Annual Water Quality report covers the drinking water quality for the City of Ann Arbor for the most recent completed calendar year. We test our water on a regular basis to ensure its safety according to City of Ann Arbor water quality goals, the State of Michigan regulation, and the United States Environmental Protection Agency (EPA) regulation.
Each Spring a new report is provided covering the previous year and provides a snapshot of the quality of the water we produced to you over that calendar year. Details are also included about where your water comes from, what it contains, and how it compares to EPA and State standards.
