Résumé
A study was conducted to find out the bacteriological quality of water during the monsoon season in local areas around Kasauli Town, and to evaluate the management of water resources in rural areas. The water samples were collected from bowries and hand pumps. As there is no municipal water supply in majority of these areas, the local residents depends mainly on these natural resources without any treatment of water. All the 14 surface water samples collected from bowries were found bacteriologically polluted with total coliform count ranging from 35-1800+. The main contaminants isolated were atypical thermotolerant E. coli, Pseudomonas fluorescence, Enterobacter cloacae, Aeromonas liquifaciens, Citrobacter freundii and Pseudomonas pseudomaleii. Among seven hand pump samples, two were found to have Coliform count 80 and 250 respectively. These two water samples were found contaminated with Citrobacter freundii and E. coli &Aeromonas liquefaciens respectively. These bacteriological contaminations appear to be both from vegetative & human or animal excreta sources. The study therefore suggested that the water from these natural resources requires treatment either by boiling or chlorination before human consumption to avoid any outbreak.
