Hydrogeochemical study of groundwater in selected areas of Balurghat Subdivision West Bengal India and probabilistic health risk assessment

Abstract

The current study, which is entitled as and#8213;Hydrogeochemical study of groundwater in selected newlineareas of Balurghat Subdivision, West Bengal, India and probabilistic health risk assessmentand#8214; newlineconcentrated on the effects on human health of the groundwater situation in the Balurghat newlineSubdivision in the Dakshin Dinajpur district of the Indian state of West Bengal. Lack of newlinegroundwater and health issues data of this area due to contamination in groundwater catalyze newlineto undertake this study. Not only have that, this study also provided a clear picture of newlinesuitability of the water quality for irrigation purposes and drinking water quality of the newlinegroundwater of the study area which were not properly investigated. This area is very much newlinebackward due to unhealthy economic condition which leads the most of the local peoples to newlinetake drinking water without any treatment. So, this study may help policy makers to develop newlinenew policies. newlineThe first chapter focused on the prominent aspects of groundwater and provided a broad newlineintroduction to the characteristics of water and water resources. Aquifer rock composition, newlinegroundwater velocity, and other variables affect the character of groundwater. Both human newlineand geogenic activities encourage the leaching of pollutants into groundwater systems. newlineFluoride and iron contamination in groundwater is a burning issue not only in the state of newlineWest Bengal, but various states in India continuously fighting with this problem and its newlineimpact on human health. Generally, western districts of West Bengal are heavily affected by newlinethis type of contamination in groundwater due to high chances of rock-water interaction. But newlinefluoride and iron contamination problem in the Garo-Rajmahal trap which mostly comprises newlinewith alluvial type of soil is comparatively newer and not well reported. The minerals like newlinefluoride and iron etc. are quite beneficial for human health but excess presence in newlinegroundwater which is heavily used for drinking and irrigation makes an unwelcomed effect newlinexix newlineon health of this study area.
