The implementation of a flux model for the application of groundwater integrated management

The paper presents a groundwater flux model that covers an area of about 10 km2 of the south-eastern part of the city of Milano (Italy), as a preliminary tool for the application of a new investigation approach. This research study is one of the goals of INCORE (Integrated Concept for Groundwater Remediation), a European funded project. The project aims at providing a cost-efficient technical administrative set of tools for optimised investigation, evaluation and management of contaminated groundwater and land in urban industrial areas. The model represents a local hydrogeological situation of a site that was polluted by hydrocarbon chlorinates and pesticides; it concerns the upper part of the aquifer in Milan, down to 50m of depth, where the considered pollution is located. The mathematical model was implemented with a 3D finite difference program, called MODFLOW (M. McDonald and A. Harbaugh, 1988–1996). The paper reports a short description of the INCORE project and the new Integral Investigation Method, and describes the implementation of a flux model to plan the Integral Investigation based on some Immission Pumping Tests (IPT’s).
