dc.description.abstractThe groundwater resources study of the Alentejo region (CCR Alentejo, 1996-1999) was carried out in several places namely Beja's Gabbros Aquifer to assess water quality for public supply and agriculture. A geostatistical study of nitrate diffuse pollution in the vicinities of Beja based on probabilistical technics was developed in the context of a MSc Thesis in co-operation with CVRM - Geosystems Center. Several basic statistics between July 1997 and July 2000 were computed. Indicator variograms for nitrate ion with 50 mg/l cut-off are presented and Indicator Kriging is performed based on parameters fitted to spherical models. Risk and probability maps used in environmental management are also included.pt
