“…Measurements of flow taken from the different monitoring stations along the length of the stream in various seasons indicate that along the stream's first 60 km between 40% and 90% of the wastewater discharged (8000 -11,000 m 3 ) percolates into ground water before it reaches the green line and the Beer Sheva stream (Table 1). This is consistent with comparable hydrological research in Israel (Melloul and Azmon 1997) and in other regions (Triska et al 1989, Zaramella et al 2003, Ryan and Boufadel 2007.…”

Although ephemeral streams constitute critical natural resources in dryland environments, water regulations and monitoring protocols typically focus on perennial streams, and may not always be appropriate for characterizing intermittent systems. The article presents findings from a comprehensive evaluation of environmental conditions in two ephemeral transboundary streams: the Hebron/Besor and Zomar/Alexander. The streams are representative of numerous watersheds which originate in Palestinian land and flow into Israel. Transboundary streams in the region exhibit high concentrations of point and nonpoint sources of pollution. Many of the region's streams that in the past had no flow except for isolated storm incidents have emerged as perennial streams, channelling raw or partially treated industrial or municipal wastes. Management of these natural resources constitutes a unique challenge because of the complex local political circumstances. The article presents chemical and biological monitoring results, identifying high levels of non-point source nutrient runoff during rainfall events and high percolation of contaminated stream water during its flow that should be addressed in future restoration strategies. The practical challenges associated with the monitoring of ephemeral streams are also discussed with suggestions for future studies and management efforts.

“…One of the first papers using major ions and trace elements for a geochemical assessment of GW salinization in the Mediterranean area is the paper by Mercado [58] that analyzed the chromatographic effect of Israel coastal aquifers during salinization and freshening due to their cation exchange capacity as a preliminary tool to delineate whether the aquifer is salinizing or freshening. A decade later, another simple approach was proposed by Melloul and Azmon [59], where groundwater quality trends of selected species were proposed as a qualitative indicator of aquifer salinization and aquifer pollution by anthropogenic sources. More recently, several papers have focused on the origin and distribution of GW salinization either in porous aquifers [60][61][62][63][64][65][66], especially in arid and semiarid regions of the Mediterranean basin [67][68][69][70][71][72][73], or in fractured aquifers [74][75][76][77][78][79], by means of a detailed geochemical study.…”

The Mediterranean area is undergoing intensive demographic, social, cultural, economic, and environmental changes. This generates multiple environmental pressures such as increased demand for water resources, generation of pollution related to wastewater discharge, and land consumption. In the Mediterranean area, recent climate change studies forecast large impacts on the hydrologic cycle. Thus, in the next years, surface and ground-water resources will be gradually more stressed, especially in coastal areas. In this review paper, the historical and geographical distribution of peer-review studies and the main mechanisms that promote aquifer salinization in the Mediterranean area are critically discussed, providing the state of the art on topics such as actual saltwater wedge characterization, paleo-salinities in coastal areas, water-rock interactions, geophysical techniques aimed at delineating the areal and vertical extent of saltwater intrusion, management of groundwater overexploitation using numerical models and GIS mapping techniques for aquifer vulnerability to salinization. Each of the above-mentioned approaches has potential advantages and drawbacks; thus, the best tactic to tackle coastal aquifer management is to employ a combination of approaches. Finally, the number of studies focusing on predictions of climate change effects on coastal aquifers are growing but are still very limited and surely need further research.
