A Planned Industrial Sector (Law 13744) is projected to be installed near Tornquist city. Hydrologically is located in the Sauce Chico river basin. The vadose zone (VZ) of the studied area is characterized by loessic sediments and an impermeable and discontinuous layer of calcareous sediments at the upper portion. The phreatic aquifer is contained in the Sedimentos Pampeanos. To determine the potentially of a contamination event affecting the subsoil and the aquifer, the transit recharging was evaluated by Balshort V.3 program. To evaluate the transport of non-reactive and reactive solutes in the VZ, with HYDRUS 2D/3D program, the transit recharging was considered. Enough long transit times to warrant the pollutant degradation were defined. The physical characteristics of the hydrogeological system support the development of certain industrial activities in the studied area.
