ABSTRACT
Information about vulnerability of groundwater to contamination is
essential to facilitate groundwater planning and management. The vulnerability
of shallow groundwater to con-tamination in and around Midnapur-Kharagpur
towns,West Bengal, India, is evaluated using the DRASTIC method within
a Geographic Information System (GIS). DRASTIC parameters are calculated
from geological, soil and elevation contour maps and groundwater level
data of the study area, and thematic maps are prepared. Finally, the maps
are integrated through the DRASTIC model within the GIS to demarcate vulnerable
zones. In the present study, DRASTIC indices for both generic industrial-municipal
and pesticide pollutants are derived and vulnerability maps for both classes
are prepared. The result of the study shows that 50 percent of the area
is highly vulnerable to industrial and municipal pollutants and more than
81 percent of the area is highly vulnerable to pesticide pollutants.
