Fifty water samples were collected from Mahmoudia Canal, sewage water well water and examined bacteriologically for rapid detection of faecal coliforms using 7-hours faecal coliform test the standard membrane filter technique and the most probable number test.
The obtained results by the 7-hours faecal coliform test were nearly similar to those of the membrane filter technique. On the other hand, the most probable number offaecal coliform was more superior than the other two methods.
Moreover, the 7-hours faecal coliform method provides a direct, simple, rapid, accurate and requires only seven hours.
