"Definitions that begin with the letter "I." "Inactivation ratio" with respect to viruses means the ratio that quantifies inactivation of viruses. The sum of the virus inactivation ratios, or total virus inactivation ratio shown as [SIGMA](CTcalc)/(CT99.99). "CT or CTcalc" is the product of "residual disinfectant concentration" (C) in mg/l determined before or after the first customer, and the corresponding "disinfectant contact time" (T) in minutes, i.e., "C" x "T." If a public water system applies disinfectants at more than one point prior to the first customer, it must determine the total percent inactivation or "total inactivation ratio." In determining the total inactivation ratio, the public water system must determine the residual disinfectant concentration of each disinfection sequence and corresponding contact time before any subsequent disinfection application point(s). "CT99.99" is the CT value required for 99.99 percent (4-log) inactivation of viruses. CT99.99 for a variety of disinfectants and conditions appears in Tables D-7, D-9, D-11, D-13 and D-14 in the EPA Handbook for Optimizing Water Treatment Plant Performance Using the Composite Correction Program.J.
