Hydrotherapy and bottling mineral water exploitation requires a detailed placement of the catchment and the aquifer’s vulnerability assessment for further protection perimeter design. The DRASTIC methodology was the starting point index used for the herein introduced “specific DRASTIC”. It is possible to say that hydrogeologically the area suggests a predominant low vulnerability. However, hydrogeological and structural characteristics (e.g., granitic fracturation), indicate an extremely high vulnerability in which concerns to the Termas de Fonte Santa catchment. The "specific DRASTIC” index is held by local parameters in order to downscale the key properties for local vulnerability mapping and further quantification of the potential for contamination of the aquifer. The Termas de Fonte Santa is classified as very high to extremely high vulnerable and in need of protection and conservation.
