Abstract
Pollution of groundwater is a serious issue because aquifers are susceptible to contamination from land use including indiscriminate dumping of refuse and other industrial waste. Vulnerability assessment is an essential step in assessing groundwater contamination. DRASTIC model was adopted for the venerability assessment of Groundwater in College of Education Warri in Delta State. Electrical resistivity method was used to determine some of the DRASTIC variables. The result showed that the depth to water table varies from 40-90m in the study area, the net recharge varied from 1110-1987 mm/day, Soil Media was found to be friable sand stone to clayey Sandstone, Topography was 80-90 ft with slope range of 1º to 2° , Impact on Vadose was moderate and Hydraulic Conductivity was 0.94-2.1 Gal/Day. The vulnerability index findings of the area was from 100-150 which showed that the west and the south-south portion of the area are highly prone to contaminant infiltration. Result of the geochemical analysis of groundwater and soil in the area was used to validate the DRASTIC model result and the two results agree.
