Enumeration Test
Microbiological monitoring in support of drinking water quality assurance covers a range of indicator organisms. Fapas drinking water microbiology proficiency tests are enumeration and identification tests which cover the major indicators of colony counts, total coliforms (with a separate E. coli test), enterococci, Pseudomonas and Clostridium.
Colony counts are traditionally used to determine the hygienic quality of potable waters, and these are typically aimed at enumerating Enterobacteriaceae and coliforms (incubating at 37°C) and heterotrophic bacteria (incubating at 22 °C). A different temperature is used to assess the bacterial load in cooling tower waters which is 30°C.
Proficiency testing provides a means to monitor laboratory results by comparing data between laboratories using technically equivalent methods. Participation in this PT allows laboratories to be compared with their peers using the same incubation temperature of 30°C which is not directly comparable to enumeration methods at other temperatures.
