The final test results have been received from the lab.
The suspected culprit of the issue is iron bacteria, which is not hazardous to your health, but can cause unpleasant taste and/or odors.
Madison Well 3 has been offline since our public works department learned of the issue. With the final results, the engineers, DEQ, and public works department will now work together to try and determine how this happened and work on a solution.
