Clean Ganga? Haridwar only place out of 39 to have 'A' quality water
New Delhi: Only one out of 39 locations through which the Ganga river flows had clean water in the post-monsoon period this year, the Central Pollution Control Board (CPCB) has said in its latest study. As many as 37 of the 41 locations through which the Ganga river flows reported moderate to severe water pollution in the pre-monsoon period this year, according to the 'Biological Water Quality Assessment of the River Ganga (2017-18)' report that was recently made public by the CPCB in compliance with a Supreme Court direction.
The water quality of the river was either clean or slightly polluted at only four out of 41 locations during the pre-monsoon period and at only one out of 39 locations post-monsoon, it said, adding that Haridwar is the only location where the river was 'clean' in the post-monsoon period. In the report, qualitative analysis of samples that were taken during pre- and post-monsoon period were analysed and put under five water quality classes — clean (A), slight pollution (B), moderate pollution (C), heavy pollution (D) and severe pollution (E).
According to the report, 34 areas showed moderate pollution in the river while three areas recorded severe pollution in the pre-monsoon period in 2017-18. The report also said in Uttar Pradesh, two major tributaries, River Pandu and River Varuna, are increasing pollution load of the Ganga.
"On mainstream of River Ganga, although none of the locations were found to be severely polluted but most are in moderate pollution range," the study said. As many as 37 of the 41 locations through which the river flows, reported moderate to severe pollution in the pre-monsoon period this year, it said.
In another study titled 'Comparison of Biological Water Quality of River Ganga (2014-18)', it was found that Ramganga and Garra river water was in the heavy pollution range in the post-monsoon season during 2017-18.
