This paper presents the results achieved from modelling by the VISUAL MODFLOW software for uncontrolled waste disposal area, in Poços de Caldas city, State of Minas Gerais, Southeastem of Brazil. Based on geology, geotechnics, hydrogeology, climatic characteristics, geometry of the area and pollutant source types, 16 scenarios were modelled. The results were compared with geophysical information and fíeldwork data. The more compatible results are related with a scenario where different dispersivity parameters, Langmuir isotherms and continuous concentration source were considered.
