KONFIRM is an MMO-MUG test to detect and confirm the presence of total coliforms or E. coli in drinking water samples. Konfirm will detect the occasional MUG negative E. coli not detected in other systems of this type by also including the indole test. The active ingredients in Konfirm are incorporated into a tablet containing growth factors, indicators, and inert ingredients, producing easily read reactions which will consistently indicate and confirm the presence of fecal contamination by simple, easy to read reactions. Non-coliform bacteria are inhibited and do not interfere with the test during the specified incubation times. The test is useful for testing private water sources for such contaminants.
