Abstract– India’s urbanization and industrialization have made water pollution a serious problem. Monitoring biological parameters offers a quick, simple, understandable, economical, and time-efficient way to assess the overall effects of pollution. The river’s biological factors must be evaluated in order to determine its current state because its properties are always changing. Faecal coliform levels at three locations in the Punpun River were studied, and the results showed notable seasonal changes. The pre-monsoon concentrations at the upstream location ranged from 2,700 to 8,600 MPN, suggesting significant contamination from agricultural runoff and local discharges. Concentrations rose during the monsoon because of increased river flow and runoff. As the river stabilized and sediment settled, post-monsoon levels dropped. Elevated pollution levels were suggested by the downstream site’s regularly higher pre-monsoon faecal coliform values. The average faecal coliform concentration was 6,725.56 MPN for all sites, indicating variation in bacterial contamination. There were no discernible variations amongst the sampling stations, according to statistical analysis, indicating widespread effects from regional pollution sources.
