Abstract

The groundwater system responds slowly to contamination events and the travel times to reach the groundwater zone are often long. Cleaning and restoring contaminated groundwater is often technically problematic and expensive. Moreover, finding alternative sources for water supply is not always possible. Therefore, the most effective and realistic solution is to prevent the contamination of groundwater through. GROUNDWATER VULNERABILITY is considered an intrinsic property of groundwater and can be defined as the possibility of percolation and diffusion of contaminants from the ground surface into the groundwater system (Babiker et al. 2005). GROUNDWATER VULNERABILITY is a relative, dimensionless and characteristic that cannot be directly measured in the field and depends on aquifer characteristics, geology and hydrogeology. Many different methods have been developed for assessing this vulnerability (Vrba and Zaporozec 1994). One of the most commonly used of method of GROUNDWATER VULNERABILITY assessment is the DRASTIC method. In the present study, vulnerability assessment was carried out to evaluate the potential for groundwater contamination through the construction of a map for groundwater aquifer system in the study area. For this purpose the combined use of the DRASTIC and geographical information system (GIS) demonstrated as an effective method for groundwater pollution risk assessment.
