Ganga is suffering from extreme pollution level, which affects a large amount of population who live close to river. The amount of toxins, chemicals and other dangerous bacteria found are now almost 3000 times and levels of Coliform bacteria is over 2800 times the safety level considered by the WHO. The sources of pollution of Ganga can be classified broadly into two categories namely. Point sources-Industrial waste, Municipal sewage Non-point sources -Run- off from agricultural fields carrying chemicals and fertilizers etc Ill effects are decreases the level of dissolved oxygen (DO) in water. The decrease in levels of DO can harm aquatic animals such as fish and amphibian. And Pollution of Ganga can cause significant changes in organism metabolism and other adverse cellular biology effects. It causes many waterborne disease like cholera, hepatises, typhoid, amoebic dysentery, gall bladder disease and according to a study 80 per cent of stomach diseases in India are caused by polluted water.
Different studies revealed the deteriorating health of the river Ganges. The existing action plan is not able to treat this problem effectively. We expect from the participants various new feasible techniques and suggestions to facilitate the action plan. Your solution will be judged on the basis of your innovative ideas and how far that will be achievable including cost factors and other environmental aspects.
1. Give a brief note on progress and government’s approach on Ganga rejuvenation so far.
2. Suggest some new economical techniques or improvements in existing techniques so that efficiency of treatment can be improved.
