Description
Este artigo deriva de uma comunicação apresentada em International workshop “Uranium, Environment and Public Health”, UrEnv 2013. The main purpose of this work is the uranium spatial distribution patterns in groundwater, within the Águeda river
transboundary watershed (Portugal-Spain). Mineral resources occur distributed throughout the watershed, mainly sulphide and
uranium minerals. Sixty-five groundwater samples were analyzed. Geostatistical modeling was used, throughout conventional
variography and Sequential Gaussian Simulation algorithm, to model the groundwater uranium spatial distribution. A hundred
simulations, differing in their initial random-number seed, were performed. Spatial uncertainty evaluation allowed the definition
of future monitoring and sampling strategies as well as the measurement of remediation possibilities. Uranium hot spots are strongly
embedded in the central area (Ciudad Rodrigo).
