On the basis of hydrological, hydrogeochemical and geological studies, 324 sampling points were selected. All groundwater sampled were collected twice, from October to December 2004 and from February to May 2005, and were analysed to determine the concentration and spatial distribution of the VOCs in the aquifers. The need to analyze a large number of samples in a short space of time so as to obtain quantitative analyses in trace concentration levels spurred us to create a new analytical method, both simple and sensitive, based on HS-SPME/GC/MS. The concentrations of VOCs measured in industrial and intensive agricultural unconfined aquifers were greater than those found in other aquifers. Tetrachloroethylene, chloroform, trichloroethylene and 1,2-dichloropropane were the most frequently detected VOCs. However, they exceeded the guideline values proposed by the EU in only three aquifers located near to industrial and intense agricultural areas.350 30 - PublicationOpen AccessContamination of coastal aquifers from intense anthropic activity in south-weastern Sicily, Italy(2006)

C.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Palermo, Palermo, Italia; ; ; ; ; ; ; ; This study was conducted in western Sicily, in the Marsala and Castelvetrano-Campobello di Mazara coastal plain area. The economy of the area is mainly based on intense farming of specific agricultural crops (citrus, grapes, olives and others in greenhouses). These activities require a substantial and growing amount of water drawn, essentially, from local aquifers. In summers, water demand increases due to high population density. In order to satisfy this demand, numerous wells were drilled throughout the area, in some cases with a density of 10 wells / km2. The uncontrolled groundwater exploitation in the last 10 years has resulted in a drastic decrease in water well levels, consequently allowing extensive seawater intrusion. The main aquifer is a sandy-calcarenitic, plio-pleistocenic complex, interbedded with clayey-marly layers in the lower layers. Multi-layered aquifers are present with the upper layers unconfined. Related studies are also being conducted in this area including monitoring of over 100 wells to better define potential groundwater resources. More specifically, the authors of this study, who are part of the U.O. 4.17 of the Gruppo Nazionale Difesa dalle Catastrofi Idrogeologiche (G.N.D.C.I) (National Defense Group for Hydrogeologic Catastrophes) of the Consiglio Nazionale delle Ricerche (C.N.R.) (National Research Council), are completing a “Pollution Vulnerability Map” of all aquifers in south-western Sicily (1:50.000 scale) using the zoning method for homogeneous areas (G.N.D.C.I.-C.N.R. method). This map is a valid instrument for all authorities governing the management and protection of groundwater resources in the area.215 813 - PublicationOpen AccessVulnerability of Coastal Aquifers Subjected to Anthropogenic Activities in South-Western Sicily, Italy.(2004)
