"Characterization of maximum infiltration areas using GIS tools
…
The objective of the study is the identification of maximum infiltration areas, taken as groundwater infiltration zones, in order to delineate a protection strategy for municipal water supplies. In this work a methodology for the delimitation of maximum infiltration areas and aquifer vulnerability is presented based on hydrogeological criteria that describe the infiltration potential of present ground conditions in the municipality of Seixal (Portugal). The areas of maximum infiltration will be those presenting the most favourable conditions for recharge of the aquifer systems. Considering that these areas are the most sensitive to contamination risk they should be classified using criteria that reflect the vulnerability of the aquifer system to possible contamination. Thus, the evaluation of maximum infiltration areas must consider, directly or indirectly, the hydrogeological characteristics of the terrain, such as its permeability and the hydrodynamics of the aquifer system."

In France, the bottled drinks manufacturer, Perrier-Vittel, demonstrated that reforestation in sensitive infiltration zones under the guise of protection forestry, alongside co-operative agreements with farmers, proved a cost-effective measure in the protection of French aquifers from agricultural nutrient and pesticide run-off and leaching (Johnson et al., 2001)."
