After a little over a month of temporary chlorination, we have passed the two required follow-up samples with safe results, and today received our official notice from the DNR rescinding the requirement. Chlorination of our water has been discontinued.
We continue to regularly test our water for safety, and are required to perform 5 bacti tests in December before returning to normal monthly sampling.
We had to continue chlorination longer than originally expected, as we brought the level back up gradually to the DNR-prescribed measurement. We did not want to increase suddenly or overshoot the amount required; nor did we want to fail in resolving the bacteria finding.
I appreciate everyone’s understanding that this is a fairly normal occurrence with wells, and that we are required to handle the test result in accordance with EPA and DNR regulations to ensure safe water. Please contact me with any questions.
