Abstract

Bacterial contamination of drinking water in Far-Western Developmental Region of Nepal was carried out. A total of 60 samples collected from eight districts were studied by using commercial Colilert test system (IDEXX Laboratory, Tokyo, Japan) which detects both total coliform (TC) and fecal coliform (FC) (Escherichia coli) bacilli. Over all, 96.7% (58/60) of samples were positive for TC whereas 66.7% (40/60) were positive for FC. Three districts - Achham, Doti and Kanchanpur had FC positive rate of over 71.0%. These findings were indicative of high risk of outbreak of waterborne diseases in this region anytime in future.
