This article presents a case study of the application of numerical modelling to jointly assess seawater intrusion and the remediation strategy for a coastal aquifer. The case study focused on a Gas Plant site located near the coast in the South of Italy. Hydrogeology in the area is characterized by the presence of a sandy-loam phreatic aquifer, approximately 30- meter thick. Groundwater level ranges between 0 and 2 meters above sea level. The main constituents of interest in groundwater are arsenic and total petroleum hydrocarbons (TPH). A 3D density-dependent flow and transport model was implemented using the finite element code FEFLOW (©Wasy software, Diersch, 2002). Once calibrated, the model was run to confirm the effectiveness of the site emergency remedial actions already implemented, and to support further remediation planning. The model produced a numerical evaluation for the transport of the two principal target contaminants in each of the remediation scenarios evaluated
