The aim of this study was to evaluate the bacterial contamination of drinking water collected from various sources of Goalpara district, Assam, India. E.coli, Klebsiella, Streptococci and enterococcus was isolated. The bacteria showing highest rate of infection belongs to the Enterobacteriaceae family. E. coli, the highest and Enterococcus shows the lowest numbers of contamination in this study. Balijana block was recorded as the highest contaminated area and stream water was recorded as the highest contaminated source. The data shows that the cause of contaminated drinking water in this area is due to poor sanitation, as well as unawareness about personal hygiene and cleanliness. The presnece of this bacteria in the drinking water increases the risk of water borne diseases and health issues.
