ABSTRACT
The main goal of this study is the spatial identification of maximum infiltration areas and aquifer vulnerability in order to delineate a protection strategy for municipal water supplies. A two-step Geographic Information System (GIS) model is presented: (i) in the first step, hydrological parameters are classified by grades of infiltration and combined, in order to delimit the most important areas; (ii) in the second step, maximum infiltration areas are merged with hydrostatic water level layer and a final map of the favourable aquifer recharge areas is obtained as an indicator of aquifer vulnerability to potential contamination. This methodology was implemented using ArcGis 8.2 software, and applied to Seixal Municipality, an urban/industrial area near the capital of Portugal, Lisbon, where negative impact on groundwater resources is a major concern.
