We informed you on March 1 about the city’s February 2019 water quality test results that detected 1,4-dioxane in the drinking water at 0.030 parts per billion. Even though this concentration was much lower than any EPA risk levels, we believed it was important to let you know of this first-time detection. No 1,4-dioxane was detected in samples collected in March from the Huron River at Barton Pond or in the city’s drinking water. At this time, we cannot ascertain if the detection was a laboratory anomaly or due to some other unidentified source. The city's Water Treatment team's No. 1 focus is quality drinking water and with that goal in mind they collect more than 58,000 water samples and conduct more than 177,000 tests each year. With advances in testing techniques, labs are able to detect very low levels of contaminants in water samples. The presence of contaminants does not necessarily indicate that water poses a health risk. Our water quality team will continue to send water samples to an independent lab each month to test for 1,4-dioxane, and analytical testing results will be posted on the city’s website. Your interest in updates from the City of Ann Arbor is appreciated. Thank you, Please note, the current Facebook outage is preventing the city from posting this update to that platform.
