"Definitions that begin with the letter "H." "Human consumption " means

I. "Definitions that begin with the letter
"I." "Inactivation ratio" with respect to viruses means the ratio that

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

Using the Composite Correction Program.
