Multi-source water characterisation for water supply and management strategies on a small Mediterranean island

摘要: The small islands in the Mediterranean Sea suffer water shortages, aggravated by pressure from tourism during dry season. Many are affected intense and increasing human demand harsh climatic geographic nature of island terrain. present study, carried out on Favignana, Egadi Archipelago (southern Italy), evaluates regime recharge to subsurface, hypothesizes a solution for identifying areas where groundwater is most abundant, as well best management options use. By means hydrological measurements chemical analyses, specific location has been identified eastern sector optimal quality table at depth only few metres. In other more saline, due seawater intrusion, it greater depths. residents have past lived harmoniously with island, shown good ability manage resources, fed limited precipitation that comes winter, using supplement drinking supply Trapani (mainland Sicily) submarine pipeline tanker. Optimized resources could reduce volume freshwater transferred mainland.
