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. The Markanda River showed the highest concentrations of BOD, almost 198 times the acceptable range of 3mg/l while the Yamuna River faired the worst polluted river in terms Fecal Coliform concentrations. The most polluted waterways have been identified and charted for restoration projects by the CPCB.
