Figure 3

Geological and hydrogeological scheme of the study area. Black dashed rectangle indicates the area shown in Fig. 4A. Figure legend: 1) Quaternary alluvial and lacustrine complex (multi-layer aquifer). 2) Terrigenous complex (regional aquitard; Upper Miocene). 3) Upper Lias-Lower Miocene carbonate complex (aquifer). 4) Thrust fault (dashed where inferred). 5) Normal fault (dashed where inferred). 6) Major spring. 7) Groundwater flow path. The geological and hydrogeological scheme and the sketch of Italy were redrawn and modified form the “Schema Idrogeologico dell’Italia centrale” (Hydrogeological chart of Central Italy)38, freely available at: http://www.idrogeologiaquantitativa.it/?p=428&lang=it. This figure was created with Adobe® Illustrator CS6 ver. 16 (http://www.adobe.com/products/illustrator.html).
