Scenario: A reclamation facility uses raw sewage as a source of water. Calculate microbial concentrations that meet daily acceptable risk. Assume that people drink 2 L of water daily. The daily intake dose based on probability of infection [D(P:)] is 4.62 x10-7 for rotavirus, 5.61 x10-5 for Shigella, and 6.52 x10- for Cryptosporidium. How many logio reductions are required to protect public health? Assume that the sewage contains the following concentrations of pathogens: rotavirus (enteric virus) 104/100mL, Shigella 103/100mL, and Cryptosporidium 10%/100mL.
