| Title | A GYPSUM-BARRIER DESIGN TO STOP SEAWATER INTRUSION IN A FRACTURED AQUIFER AT SALENTO (SOUTHERN ITALY): PRELIMINARY RESULTS |
| Abstract | Seawater intrusion into fresh water aquifers occurs in many coastal hydrogeologic settings due to overexploitation of freshwater resources. It can be exacerbated by seawater level increases as a result of climate change on which there is wide consensus in the scientific community. Basin scale water balance deficits may be used together with hydrogeologic modelling and water quality monitoring data to track the advance of seawater intrusion. Due to the growth of population and increased exploitation of the ground water resources in coastal areas, the problem is truly global in proportion. The situation is particularly acute in the Mediterranean, the Yucatan peninsula in Mexico, the Middle East, the SE and SW United States as well as on many islands with arid to semi arid climates. Continued exploitation of limited freshwater resources can also lead to up flow of relict marine waters underlying the fresh water zone compounding the effects of seawater intrusion. This study has been designed to test the feasibility of creating a subsurface barrier to seawater intrusion by induced gypsum precipitation in fractured carbonate aquifers. The barriers design was supported by laboratory experiments and by a mathematical model which simulated sweater intrusion in a costal aquifer at Salento, in Southern Italy. The results will assist regional, national, and local water management interests to better regulate water use and protection as well as to avoid conflicts over scarce resources. |
