The concerned project was aimed to observe and analyze an incident that carried a direct connection with the issue of surface water pollution. The central focus of this project, River Panga, is a small rivulet in District Jalpaiguri, West Bengal (WB), India. It came to notice with utter shock that due to some unfortunate and unwanted cause a large number of fishes died and floated over the surface of River Panga on 10th May, 2015. This unnatural and harmful incident on aquatic life created a keen interest to carry out a quality assessment of the River water which ultimately aims to look for the preliminary cause of that situation. The water of River Panga collected from two points- near to contamination Zone (P1) and incident point (P2) after the event and analyzed in laboratory to measure some Physico-chemical parameters like Temperature (T), Hydrogen Ion Concentration (pH), Electrical Conductivity (EC), Total Dissolved Solid (TDS), Total Hardness (Total-H), Calcium Hardness (Ca-H), Calcium (Ca), Magnesium Hardness (Mg-H), Magnesium (Mg), Alkalinity, Dissolved Oxygen (DO), Nitrate (NO3-), Nitrite (NO2-), Ortho Phosphate (PO4-), Chloride (Cl-), Manganese (Mn), Iron (Fe as FeS), Arsenic (As), Total Coliform and Fecal Colifom. The findings of the analysis showed that the water of River Panga was hard. The amount of manganese present was beyond the Environmental Protection Agency (EPA) limit and iron was greater than tolerable limit of fish species. The DO level at the two study points reached at an alarming condition and this was the cause of the mortality of fishes at P2. Moreover it was evident that pollution at P2 was more than that of P1. Investigation showed that the industrial effluent may responsible for the pollution of River Panga as an industrial growth at Raninagar, Jalpaiguri is situated at the catchment area (near P1) of this river. The other important point noted at the time of inquiry that the local people, who used the water daily, suffer from skin diseases. So, the work quite significantly marked that the aquatic life and the local people who are dependent on the river water are under risk.
