| contents | Groundwater vulnerability assessment in Portugal J. P. Lobo Ferreira Manuel M. Oliveira Ciencias de la Tierra scale method effect DRASTIC comparison During the 70s and 80s groundwater vulnerability mapping in Portugal was based mainly on the interpretation of geologicalinformation in terms of vulnerability to groundwater pollution. In 1987 a parametric method for the assessment vulnerabilityto pollution was introduced by the USEPA (the DRASTIC index). In 1993 Portugal was the first European Unions Member-Stateto have its territory mapped using the DRASTIC index (1:500,000 scale). Since then several applications of the DRASTIC index,at different scales, and using different sources of base information, have been made. The use of different sources of information,with different scales and sometimes with different approaches lead to different final maps of the same area, as shown in this paperfor Setúbal peninsula, south of Lisbon. New methodologies for groundwater vulnerability assessment, based on the characterizationof different parameters, led to a comparison of the results. With this aim, a comparison between six vulnerability indexmethods (AVI, GOD, DRASTIC, SI, EPPNA and SINTACS) was carried out for an aquifer system located near Évora (Alentejo,Portugal). Conclusions for further research on vulnerability mapping are addressed at the end of this paper. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843403 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.43 |
