Studies on Bacteriological Quality of Water of Bangladesh and their Health Hazards

M. A. Rahman, F. Begum and M. S. Islam


A total of 330 water samples obtained from different sources in three different seasons were examined for the evidence of bacterial pollution and physico-chemical properties of water. The densities of total coliforms ranged from 0-6 to $ 2400, fecal coliforms 0-2 to $ 2400 and total bacterial count (log10) 0.07-0.42 to 3.95-8.91 per 100 ml. of water samples of different seasons. The degree of pollution was the highest in pond for public use in all seasons and the lowest in deep tubewell in winter and aqua mineral. E.coli, Fe.Streptococci, Salmonella and Shigella were found highest 80, 58, 46 and 58% respectively in water of ponds for public use irrespective of season. No Salmonella and Shigella were detected in deep tubewell and aqua mineral. The physico-chemical parameters of water were determined.
