Some of these defects can be corrected by additional bacterial tests to determine interference or identify nonconliform lactose fermenting organisms.

Nematodes as a source of total coliforms in a distribution system
Canadian Journal of Microbiology, 2007In a distribution system of a large North American city, recurring total coliforms and atypical coliforms were detected at the exit (distribution pumps) of a storage reservoir. The presence of total coliforms and atypical coliforms was noted when the pumps were in operation and the water temperature was higher than 18 °C.
