In Tandil city, in Buenos Aires province, Argentina, the foundry industry is one of the most important production lines. The waste generated by these industries has historically been disposed as fill material in pit quarries and brickworks of the likelihood that some of his constituents leach contacting the underground water resources. The aim of this paper is to present the preliminaries results hydrochemical and hydrodynamic study conducted in a landfill of waste foundry industries. The work is around developing a disposal site with the measurement of groundwater levels and taking water samples along an annual hydrological cycle (November 2007 – November 2008). The hydrodynamic analysis shows that the groundwater flow is from the west from a rocky area where high variance across the study area. Hydrochemistry in relation to concentrations of nitrate and electrical conductivity vary significantly upstream and downstream of the landfill.
