A city has a clear well with 50 min detention time and uses chloramines to disinfect. The chloramine concentration is maintained at 2.4 mg/L and is mostly in the form of monochloramine. Assume the concentration of heterotrophic plate count (HPC) bacteria for the flow entering the clear well is 8500 organisms/mL (which is very high but is used for illustrative purposes). Estimate the average concentration of HPC bacteria leaving the clear well. Assume that the CT you obtained for reservoir water temperature and pH is 106 for 2 log removal.
