Application of DRASTIC method for mapping vulnerability to contamination of aquifer R'mel (Larache, Morocco)

The DRASTIC methodology have been aplicated to determine the vulnerability to contamination of groundwater in the unconfined aquifer of R'mel (Larache, Morocco). The variables considered by this method have been mapped using the ARCGIS 9.3 software by mean the scan tool Spatial Analyst. The results were that 70,5% of the aquifer has a very low level of vulnerability; 17,9% low degree of vulnerability; 6,7% a moderate vulnerability, while the remaining 4,8% have no vulnerability. The application of this method was performed for the first time in this area by mean of this study and the results provide a basis for environmental management, land planning and its suitability for different uses and a starting point for future research aimed at protecting the aquifer contamination.
