2017 Water Quality Report

2017 Water Quality Report cover.jpg

​We are pleased to share our annual drinking water quality report (PDF). This report explains where your drinking water comes from, what is in it and how we keep it safe.​​

Information about perfluorinated compounds (PFOA/PFOS)

Perfluorinated co​mpounds (PDF) are typically associated with the manufacture of carpeting, personal care products, cookware (e.g., Teflon), and other products. The amounts detected in the City's raw water supply and finished water are very low, on average they are 8 to 15 ng/l (ng is a nanogram). It is only in recent history that we have been able to detect compounds at such a low level. The levels found in the City's water remain almost 10 times lower than the EPA health advisory levels. The City water utility is continuing to monitor for these compounds as well as other emerging contaminants, and remains steadfast in its effort to provide safe drinking water for its customers. If you have any specific concerns or other questions, we look forward to answering them. We can be reached at 734.994.2840 or water@a2gov.org.

​Experts agree, our water tastes good!

For the second year in a row, Ann Arbor has been recognized with high caliber tasting water.  In 2017, at the National Stage, Ann Arbor came in 4th in the water taste-off at the National American Water Works Association conference in Philadelphia.  Among 34 competitors from the United States and Puerto Rico, Ann Arbor was highly ranked.  The 2017 win built on a big victory from 2016, when we took home to top prize of best tasting water in Michigan  at the State annual conference in Harbor Springs, MI.  Each year we have beaten out some tough competitors (such as our neighbors in Chelsea).  Drink up, folks!   

Fire hydrant flushing

Hydrant flushing is part of the City's annual maintenance and done to remove minerals and ​sediment that accumulate in the water lines over the course of a year. This preventative maintenance also allows us to check and record water pressure to ensure the water system is functioning properly.

Please take advantage of our graphical map to see which areas of the city are currently having their hydrants flushed.
