Abstract
Microbial indicators are used to determine whether or not water is safe for use. Recently, concerns have been raised about the appropriate use of microbial indicators to regulate recreational use of water bodies. The present study is conducted to assess the water quality of fresh water reservoir-Adharwadi Lake, Kalyan, Dist. Thane, Maharashtra, India by using, the coliform group of bacteria as indicators of microbiological contamination. On the basis of result, it can be concluded that bacterial fauna showed seasonal variation. Wherein, the highest proportion of indicator coliforms was observed during monsoon season and lowest proportion was observed during winter season. Further it can be concluded that the water from the reservoir is not fit for human consumption as per CPCB standard limits and corrective measures are necessary.
