“…Water molecule isotopic compositions: (a) the Shafdan system, including the recharged effluents (PS-6 or at the ponds) and the recovery wells (RW); and (b) the freshwater sources, in the National Water Carrier (NWC) and in the Shafdan system. Isotope data for the Coastal Aquifer, Mountain Aquifer, Mediterranean Sea, desalinated water (DSP), and for the Sea of Galilee (SOG) were taken from previous works [3,5,8,[29][30][31][32][33][34][35]. The secondary effluents compose the heavier end-member, with δ 18 O of −1.5 ± 0.1 and δ 2 H of −4.9 ± 0.9 for 2010-2011 campaign, and δ 18 O of −1.4 ± 0.2 and δ 2 H of −1.2 ± 1.3 for 2014 campaign (Table 3).…”

“…This, together with their intrinsic association to the water molecule and their relatively inert behavior in other processes, makes these isotopes ideal for tracking different sources of water bodies during transport and mixing processes [1][2][3]. However, in many studies that applied the stable isotopes of water to assess contamination processes or managed aquifer recharge (MAR), only the qualitative or semi-quantitative aspects of "fingerprints" of mixing between different sources could be demonstrated (e.g., [4][5][6][7]). The main reason for this is the lack of unambiguous definition of end-member composition, which did not enable quantitative estimations.…”

This study examines the feasibility of tracing and quantifying the progress of different water sources along the water-effluent-SAT (Soil Aquifer Treatment) chain using 2 H and 18 O isotopes. The research was conducted at the Dan Region Reclamation Plant (Shafdan), which reclaims 135 MCM/year of effluent for irrigation. Water samples representing different stages along the chain were taken in two surveys during 2010-2011 and 2014. δ 18 O and δ 2 H values were used for mixing ratios (MR) calculations, and compared with calculated MRs using chloride and carbamazepine concentrations. The results showed a relative enrichment of 18 O and 2 H in the Israeli water system compared to the regional groundwater, due to the addition of massive quantities of desalinated water. A linear correlation for δ 2 H vs. δ 18 O with a slope of 4.5 was found for the different freshwater sources and their mixing products, suggesting evaporation-mixing effects. MR values indicate on the spreading of new type of effluent originating from desalinated water in the aquifer. A dilution model explains the isotopic compositions in the water system and of the Shafdan effluents. Water isotopes have an advantage over other tracers, due to the ability to predict their ratio in the supply system and in the effluent, based on mass balance calculations and on knowledge of water supply volumes.

“…In Spain the synergic effect of different processes involved was a good level of purifi cation. Kass et al ( 2005 ) showed that salinity and composition of groundwater in the water table region in Israel were highly variable over a distance of less than 1 km and were controlled by irrigation water and the processes in the overlying unsaturated zone. Abd El Lateef et al ( 2006 ) showed that fertile soil and desert soil were widely variable in water holding capacity, organic matter, pH value, CaCO 3 , salinity, cation exchange capacity, and soil bulk density in the topsoil.…”

The need for irrigated agriculture is growing day by day and the largest water withdrawals from renewable water resources are for irrigation. In addition, the available water resources are decreasing and we need to use non-conventional water resources for irrigation due to looming water crisis (Raschid-Sally and Jayakody, Drivers and characteristics of wastewater agriculture in developing countries: results from a global assessment. International Water Management Institute, Colombo, 35p, (IWMI Research Report 127), 2008). However, the volume of treating and using wastewater is limited due to the lack of adequate data and knowledge and/or negative effects of improper wastewater management (i.e. use of untreated wastewater). A comprehensive evaluation of what has been done is necessary in order to explore wastewater irrigation and to avoid trial-and-error policies. Although a study of wastewater irrigation from crops, soil, groundwater, health, irrigation equipments, modern technologies, and other environmental aspects is useful, management studies in comparison with other aspects can help lead to more reliable and more extensive fi ndings and fi nally a better decision on using wastewater for irrigation. The chapter presents challenges and prospects that may help decision making for the use of wastewater in irrigation.

“…Kass et al (2005) investigated the impact of irrigation on underlying groundwater (21 -24 m) quality. The salinity and composition of the top 3 -5 m of the saturated zone was found to be distinctly different from the composition of irrigation water and was comprehensively controlled by irrigation water composition and processes occurring in the overlying unsaturated zone.…”
