P-A media is accepted for reporting total Coliform values in drinking water samples . Use this media for routine testing of samples collected from distribution systems or water treatment plants.

Fast and easy this test method requires the samples to be taken in a sterile container. Add the contents of one P-A Broth Ampoule to the 100 mL of sample. Incubate the sample for 24 to 48 hours at 35° C.

Note the reaction after 24 hours of incubation. In order to determine if E-Coli is present a UV lamp will be required to show color change.
