3. Incubate the inoculated broth tubes and slants at 37°C for 24 hours.

4. Examine lactose broth fermentation tubes for production of acid and gas and nutrient slants for gram reaction and cell morphology.

5. Production of acid and gas in inoculated lactose broth and presence of gram negative rods in nutrient slants indicate a positive complete test and confirms the presence of coliforms in water sample.
