Spatio-Temporal Pattern of Groundwater Arsenic Concentration in Thick Unconfined Aquifer of Murshidabad District, West Bengal, India
Journal Title: Universal Journal of Environmental Research and Technology - Year 2011, Vol 1, Issue 3
Abstract
Groundwater is one of the major sources of drinking water in several parts of the world. At the same time it is associated with contamination and health issues. Arsenic contamination of groundwater is one of the major concerns among them. In India, many parts of West Bengal plain are severely affected by Arsenic concentration. From the severity of the problem the utmost priority is to identify the major hot spots of the arsenic concentration. To evaluate the behavior of arsenic in groundwater both in terms of spatial and temporal aspect, samples are collected from the unconfined aquifer of Murshidabad district of West Bengal, for three following years in different seasons. An important relationship is found between the arsenic concentration, rainfall intensity and the subsurface lithology.
