chlorine residual concentration or the contact time. For example, if water at the entry point to the distribution system has a free chlorine residual of 0.5 mg/L and the chlorine is in contact with the water for 10 minutes between chlorine injection and entry point to the distribution system, CT is 5 (0.5 mg/L x 10 min = 5 mg-min/L).

Unlike chlorine, chlorine dioxide does not hydrolyze in water. Therefore, its germicidal activity is relatively constant over a broad pH range (See Figures 1, 2, and 3 on Page 6 and 7). At pH 6.5, doses of 0.25 mg/L of chlorine dioxide and chlorine produce comparable one-minute kill rates for the bacterium Escherichia coli.
