Steep rise in river pollution
The Central Pollution Control Board (CPCB) in association with State Pollution Control Boards (SPCBs) and Pollution Control Committees (PCCs) have established a network of 1085 Water Quality Monitoring Stations (WQMS) along various river stretches. Water quality data in respect of Bio-chemical Oxygen Demand (BOD) has exceeded the desired water quality criteria (< 3 mg/per litre) in 150 river stretches covering 36 rivers. The major cause of rising organic pollution particularly BOD in these rivers is due to discharge of untreated and partially treated domestic effluents by various municipalities across the country. Details of number of polluted stretches and rivers statewise are at Annexure.
