Sample had a total chlorine residual of 0.29 mg/L, a bit lower than desired. Additionally Rick noted sample collected during heavy rain. City is currently cycling water through storage reservoirs in attempt to create a higher chlorine residual in this area. All three repeat samples taken on 11/16, came back coliform absent on 11/17. Rick notified Portland and Rockwood of positive routine, but no groundwater was used, so no triggered source samples needed. ACTION NEEDED: No action at this time. City to continue with routine coliform monitoring.
