The Mahananda river is a vital river in India and Bangladesh, because the people of both the countries use the river water continuously and other people of Malda are highly captivated with this river water. But, at this point being the river Mahananda is facing a heavy as well as microbial pollution problem thanks to several reasons. The aim of this study is to gauge that the water quality of the river and mainly to analyse the suitability for various purposes like drinking, agricultural and industrial uses. This can be why this study on the Mahananda River is extremely more important for this area. In this study, samples from disposition sampling stations of north bank of the river Mahanada near Mahananda bridge were collected in Feb. 2019 to July 2019 and evaluate the various water quality of this river. The physicochemical evaluated values of these sampling stations continuously exceeded the upper permissible limit. The bacteriological parameters are within the river Mahananda showed that the coliform organisms and a few pathogenic bacteria is extensively high within the river water which indicates that the unsuitable to use of direct water for any domestic activities by the municipality areas of Malda town.
