Abstract(s)

The high spatial variability of groundwater contaminants is a non-stationary process, as spatial variability is strongly dependent on several externalities. The herein work shows a first approach to the construction of spatial distribution patterns for sensitive contaminants in groundwater, within the transboundary watershed of the Águeda River. The obtained results points out to the old mining activities as a serious environmental risk factor. The obtained maps showed to be suited for assessing the environmental impact of the considered contaminants and could facilitate the improvement of local groundwater systems’ management and the development of specific monitoring activities.
