Overview
The Hach P/A Broth is ideal for screening drinking water samples for total coliforms. The method is a simple modification of the multiple-tube method. It uses lactose and lauryl tryptose broths with bromcresol purple, which detects acidity formed during lactose fermentation by the bacteria.

Incubation
Simply combine 100 mL of sample and P/A Broth, incubate for 24 hours and check for a color change. A yellow color indicates the presence of total coliforms.
