36 WATER SUPPLY Analytical Methodology • • Total coliform analyses are to be conducted using the 10-tube MTF technique, the MF Technique, the PA coliform test, or the minimal media ONPG-MUG test (Autoanalysis Colilert System). The system may also use the five-tube MTF technique (20-ml sample portions) or a single culture bottle containing the MTF medium as long as a 100-ml water sample is used in the analysis. A 100-ml standard sample volume must be used in analyzing for total coliforms, regardless of the analytical method used.
