dc.description.abstractMany water utilities are required to monitor source water for the presence of total coliforms, fecal coliforms, or both. The Colilert system, an application of the defined substrate technology, simultaneously detects the presence of both total coliforms and Escherichia coli directly from a water sample. After incubation, the formula becomes yellow if total colifonns are present and fluorescent at 366 nm if E. coli is in the same sample. No confinnatory tests are required. The Colilert system was previously assessed with distribution water in a national evaluation in both most-probable-number and presence-absence formats and found to produce data equivalent to those obtained by using Standard Methods for the Examination of Water and Wastewater (APHA, 1985). The Colilert system was now compared with Standard Methods Multiple-Tube Fermentation (MTF) for the enumeration of total colifon11S and E. coli from surface water. All MTF tubes were confirmed according to Standard Methods, and subcultures were made to identify isolates to the species level. Colilert tubes were sub-cultured to determine if color changes were specific to the target microbes. The Colilert system was found equally sensitive to MTF testing by regression, t-test, chi-square, and likelihood fraction analyses. Specificity of the Colilert system was shown by the isolation of a species of total coliform or E. coli after the appropriate colour change. The Colilcrt test can be used for source water samples when enumeration is required, and the benefits previously described for distribution water testing-sensitivity, specificity, less labor, lower cost, faster results, and no non-coliform heterotroph interference-are applicable to this type of water analysis. This study demonstrates that there is prevalence of microorganism can be found in water tanker and should be treated more regularly or often to prevent consumers or user from contacting these coliform disease which is harmful to human lungen
