Aquatic life in the Ganga is set to flourish due to considerable improvement in level of dissolved oxygen in more than a decade, feel experts who are camping here and carrying out research.
While the dissolved oxygen level has achieved the required standard, the hydrogen (pH) level too has been found highly satisfactory in the water.
A team of experts drawn from various institutes and scientific bodies, including Indian Space Research Organisation (ISRO), recently had collected river water samples at 20 points in six highly polluted river banks – Ganga Barrage, Bhaironghat, Parmat, Shuklaganj, Jajmau and Wajidpur. This team is on a two-year long project to monitor the quality of Ganga water.
While laboratory tests of the water samples revealed a pH level of more than 8.5 milligram per litre, the dissolved oxygen level was 2.5 milligram per litre of water.
“It is high encouraging for us and the aquatic life,” said Prof Pravin Bhai Patel of CSJM University Kanpur and principal investigator in the project.
According to UP Pollution Control Board (UPPCB) the water quality of the river has improved due to two reasons. First, the sewers has been tapped and there is complete control over tannery waste water going into the river. This has checked the oxygen depletion both upstream and downstream
