Experimental results in sector C are presented in Tables 11 and 12. Just as sector B, total coliform were enumerated by the technique earlier described (SimPlate). Positive total coliform sample was recorded only in the steel pipe segment. As seen earlier, the same level of total coliform (10 CFU/mL) was recorded in sector B due to perfect mixing in sector A earlier explained.
