This hydrogeological study has been performed in the framework of a LIFE + project (LIFE11/ENV/IT/275 ? ECOREMED ). The study area is a large flat area (> 1500 km2) located in Campania region (Southern Italy). In the first phase, completed in 2014, the study consisted in the synergetic approach among different scientists to attain to the environmental characterization of the whole area. The second phase, started in 2015, was focused on the hydrogeological characterization of small sites (from 3000 m2 to 4500 m2), and it included a detailed investigation survey, based on boreholes drilling, slug tests, pumping tests, hydrogeochemical monitoring, etc. The site-scale study showed the important role of small lenses of impervious materials together to the differences in the flowpath for groundwater above and under impervious materials and the flowpath at regional scale. Finally, the hydrogeochemistry gave important results about the groundwater quality and the contamination state.
