The Central Water Commission (CWC) has recently prepared a report on water quality scenario of our rivers and has evolved a methodology for identifying hot spots in Indian rivers. The water quality data is based on the average values observed during the last ten years (2001-2011) at 371 monitoring stations of CWC on almost all major, medium and minor rivers in India. Please find below a letter (dated November 5, 2011) from South Asia Network on Dams, Rivers & People, New Delhi to the Chairman, Central Water Commission stating its concerns regarding the report.
