Geochemical evidences of landfill leachate in groundwater

摘要: Abstract To evaluate the environmental risks associated with leachate flowing into groundwater resources, in present research, a hydrogeological and geochemical monitoring of two principal aquifer systems developed below landfill Sant'Agostino (Ferrara Province, Northern Italy) was performed. Several stratigraphic columns penetrometric tests have been analysed order to reconstruct detail lithological model underground. The integrated elaboration data allowed obtain information make inferences on i) influence contamination underground resources (high concentration same elements, like Cl, Al, Zn, Pb, Cr, Ni); ii) contribution frequency variability (sand–peat–clay) propagation process contaminant elements system; iii) importance position network identification pollution protection water resources.
