Abstract: The paper presents an evaluation of the environmental impact of inadequate solid waste disposal in Municipal Solid Waste landfills in southern Brazil. It was found that inorganic contamination can reach critical levels according to the reference values recommended by the Brazilian environmental protection agencies. The physical-chemical parameters (granullometric analysis, pH, CEC, TOC and heavy metal concentrations) and mineralogical analyses were assessed for the potential mechanisms of retention and migration of contaminants in surface soil and water in the studied area. The relative abundance of the reactive mineral phases are the primary controllers of sorption processes in soils, and plays a critical role in the regulation of contaminant fate and transport. Furthermore, phytoremediation experiments were conducted with Impatiens walleriana Hook. f., a flower species well adapted to the Brazilian climate. I. walleriana was effective in removing metals from cont!
aminated soils and showed bioaccumulation of Cu, Zn, Cr and Ni. The remediation program proposed here is inexpensive as this species adapts itself easily.
