Apocalypse of Water Born Diseases in Kolkata
Journal Title: IOSR Journal of Environmental Science, Toxicology and Food Technology (IOSR-JESTFT) - Year 2019, Vol 13, Issue 1
Abstract
Unwise growth and development of Kolkata is leading the city towards a typical health crisis. The bio-physical environment of city is degrading very rapidly because continuous diagonal subsurface flow of water is increasing the amount of soluble sediment, silt and clay along with huge amount of minerals. Thus these sub surface flow has generated voids and tunnels in the sub surface condition which are prominent in the either side of river Ganga and the either side of Adi-Ganga channel and Bag-jola canal. All these water bodies are carrying huge amount of coli form bacteria. When such polluted water is entering the sub surface voids and tunnels, they are contaminating ground water and by this way diarrhea like disease are spreading. Unwise growth has also restricted vertical recharge and discharge of ground water. As a result when water is passing diagonally they are getting much more time and passage to pass and thus these polluted substances could easily reach to the level of ground water, not only that when water flow diagonally they also getting much more time and passage length and by this way the rate of arsenic contamination is also increasing day by day. All these together leading Kolkata towards a huge health crisis in near future. Kolkata is a degrading city, not only in its altitude but also degradation has occurred in its ecosystem and bio physical environment. The historical growth perspective of the city like Kolkata indirectly indicates its causes of environmental degradation. So, to analyse its overall environmental condition we had organised field trips to identify the causes of such degradation.
