2/11/2022 Bondurant Low Total Chlorine Residual External Inbox Casey, Nathan Feb 10, 2022, 3:52 PM (21 hours ago) to me, Mike, Josh, Jeff Janet, Today at 12:21 pm, we had a low total chlorine residual event at the Bondurant Booster Station. When the booster pumps started, the residual dropped below 1.5 mg/L for less than 5 minutes. The sodium hypochlorite flow was going the whole time. See the attached trend. We recently did maintenance on this analyzer and had some problems with calibration. We hope we have it addressed now. Please let me know if you need any additional information. JANET GASTINEAU
