Abstract:
Upper lake of Bhopal is a major source of potable water supply providing 35 % of the total water supply to the city dwellers. The demographic alteration in last two decades coupled with changes in the land use along the fringe areas of the lake resulted in substantial increase in pollution load. Majority of the pollutants are brought into the lake through 3 major inlets. The study shows that inflow of nutrients i.e. of Nitrate-Nitrogen (0.322298 Metric tons) and of phosphorus (1.267432 Metric tons), are the major contributing factors for pollution of the lake.
