ABSTRACT
In the assessment of the bacteriological quality of water from 1,500 drills World has not in Burkina-Faso, three methods have been analyzed comparatively. The first, relying upon bacterial production of H2S as indicator of faecal pollution and proposed by Indian workers, has been found unreliable for determining water potability. The second, based upon the nitrate content of water, is unable to reveal water contamination by human and animal excreta. The third method, employing a membrane filtration, is to be commended since it is well adapted to the Sahelian conditions. Simple, reliable, of low cost, this method is providing the quality assurance of water potability, a requirement which must accompany the drilling programs.
