Abstract
From ancient times the arid zones of Sahara, south Algeria, stay in a good state without signified contamination with biological and chemical matters. At the last five decades, the zones show large movement of population, therefore that became a new source of microbial and chemical contamination. The microbiological quality of drinking water has been evaluated in 28 samples from underground wells and foggara water which were analyzed. The essential microflora : aerobic bacteria (29,33 ± 0,44) cfu per100 ml, total coliforms (6,6 ± 0,15) cfu per 100 ml, fecal coliforms (2,33 ± 0,42) cfu per 100 ml and fecal streptococci (1,51 ± 0,66) cfu per 100 ml. The pH ranged from 6,22 to 7,34. Likewise, in 100 % of drinking water more than 71,42 % was non drinking water.
