Abstract |
Data from four comparative studies were analyzed to compare the recovery of total coliform bacteria from drinking water using the presence-absence test, the multiple fermentation tube procedure and the membrane filter technique. Combined recoveries showed the presence-absence test detected significantly higher numbers of samples with coliforms than either the fermentation tube or membrane filter methods, P<0.01. The fermentation tube procedure detected significantly more positive samples than the membrane filter technique, P<0.01. The presence-absence test offers a viable alternative to water utilities using frequency-of-occurrence monitoring for compliance regulation. |
