The current world is fighting with several issues like Covid- 19, Poverty, Malnutrition and many more. But there are some other issues which are still ignored by considering as less important. Among these least concern issues death due to drinking of contaminated water or ingestion of food come in contact with polluted water holds a major percentage. The study was conducted to determine the quality of water contamination trend in Goalpara district of Assam. The presence of fecal and total coliform were tested by Most Probable Number as well as Membrane filtration tests (MF) to rule out any chance of missing out any positive sample. During the study we identified the causative agent which contaminates the water in the targeted district of Assam, India. Water samples were collected from drinking water supplies and from routine household chores. During the study, evidence of microorganisms such as Escherichia coli, Streptococci, Staphylococci and Klebsiella were found. Escherichia coli were isolated from most numbers of samples, whereas Shigella spp. has the lowest contamination rate. The water with highest contamination rate was from Rangjuli development block and Lakhipur development block gave the lowest water contamination rate. The most prevalent bacteria were Escherichia coli.
