Water Quality Evaluation in Akilpur lake, Dighwara, Saran of North Bihar

Abstract

Akilpur lake is surrounded by agricultural lands and cover about 1500 meter in length and 300 meter in width and connected occasionally with Ganga river in flooding period of the year. The agricultural and anthropogenic activities increasingly polluted the water quality of the lake. This research was carried out to monitor the water quality status of the lake on the monthly basis from January 2021 to December 2021. The water samples were collected from inlet, mid-lake, and outlet sites and analyzed for different physical and chemical parameters, following the standard American Public Health Organization methods. The results were compared with surface water quality standard given by Bureau of Indian Standards. It was observed that mid-lake water was not much affected by different pollution sources as compared to inlet and outlet waters. The lake water was observed increasingly polluted than earlier and there is need of care to monitor lake for sustainable perspective.
