The aim of the present work is to improve the study of hydrogeochemistry and hydrogeology in a strongly industrialized area, where two plumes of organic chloride solvents have been developing since1970.

Abstract

The aim of the present work is to improve the study of hydrogeochemistry and hydrogeology in a strongly industrialized area, where two plumes of organic chloride solvents have been developing since1970. The reference area width (400 km2) allows to include the contaminant sources and to analyze the current trend of pollution events and their influence and effects on water quality. The data for this study have been released by several companies and institutions and have been processed through a three-steps procedure. The first step concerns the collection of analytical data for the hydrogeochemical characterization and the piezometric data elaboration; the second step concerns the three dimensional elaboration of stratigraphic data to map the lithological heterogeneity; the last step is dedicated to groundwater flow and pollutant transport modelling. The results allow to characterize the site from an hydrogeological and hydrochemical point of view, suggesting an hypothesis to explain the contamination path and a possible emergency intervention to protect the wells of the Novara pumping plant. In the future obtained results will be verifird by extending the simulated area and by taking into account the degradation products, which will be expressly monitored on the site.
