How do I know if 1,4-dioxane is in my drinking water?

The following information can tell you if 1,4 dioxane is in your drinking water:

  • Do you live or work in the plume area and get your water from a well? (See a map of the plume area (JPG).) If you live in the area south of M-14, north of West Liberty Street, east of Wagner Road, and west of the Huron River, you might live in the area called the Prohibition Zone. Properties in the Prohibition Zone are connected to the City of Ann Arbor’s municipal water supply and should not be using well water for any reason. The MDEQ has contacted the property owners in the Prohibition Zone. If you have not been contacted, you’re not likely in the Prohibition Zone or you are already on city water. You can call the MDEQ or Washtenaw County Public Health to be sure. 1,4-dioxane has not been detected in the City of Ann Arbor’s drinking water. Properties in other areas of the plume or near the plume edges that use drinking water wells are tested for 1,4-dioxane on a regular basis.
  • Is your water being tested? The MDEQ has contacted you if your property is located directly over the plume or near the edges of the plume. If you have allowed it, your water has been tested by the MDEQ. The frequency with which your water is tested depends on your location. You will get your results from every test in the mail. The MDEQ also has a database of monitoring results on their website. If your water tests show a level of 1,4-dioxane above the current cleanup criterion set by the MDEQ, other sources of water will be provided to you.
  • None of these things apply to me, but I am using well water. If you have not been contacted or your well water isn’t being tested, but you have concerns, you can call Jennifer Conn at Washtenaw County Public Health or Dan Hamel at the MDEQ to talk about where you live or work and if your well water may be at risk.
  • If you have a well and want to know if your water is affected by the plume, please contact:
