A 2009 report by the Central Pollution Control Board (CPCB) titled “Status of Water Quality in India-2009” lists the most recent results from a water quality study using 1700 aquatic monitoring stations across India. Data retrieved from streams, rivers, lakes, tanks, and groundwater sources indicate that organic pollution, particularly Biochemical Oxygen Demand (BOD) and Coliform, are the major sources of pollutants.
