Abstract: Eighteen ram samples from Israel have been analyzed for their chemical composmon and S7Sr/S6Sr ratios The Sr-Isotoplc rahos lie In the range 0 7078 and 0 7092, and the Sr concentrations vary from 1 × 10 -4 to 9 x 10 4 meq Sr/l.
Soluble salts in rainwater are inherited from three major natural sources, seaspray, Recent marine minerals and mineral dust eroded from rock outcrops and soft A mixing model is formulated to apply the chemical composmon of rain (CI and Sr 2+) and ~ts isotopic 87Sr/S6Sr ratio, for the identification and est~mahon of the Sr sources.
All the samples fall within the m~xing space predicted by the model for the three end members mentioned above The data indicate that the most important non-seaspray source contributing d~ssolved salts to the rams m Israel comprises a mixture of Senoman to Eocene chalk (and its weathering products) and Recent marine minerals, from local and imported sources.
Most of the samples (67%) contain 50% or more non-seaspray Sr 0 e, Sr dissolved from dust or Recent marine minerals), whereas 56% of the samples display 87Sr/86Sr ratios lower than 0 7090. The rest represent mixtures of seaspray and Recent marine minerals.

Bahir, M., Ouhamdouch, S., & Carreira, P. M. (2018). Geochemical and isotopic approach to decrypt the groundwater salinization origin of coastal aquifers from semi-arid areas (Essaouira basin, Western Morocco). Environmental Earth Sciences, 77(13), 485.
Abstract: In arid and semi-arid areas, the groundwater is the main source of water supply and agricultural activity. Overexploitation of coastal aquifers and pollution vulnerability are among the main problems related to groundwater resources assessment and management in these zones. In fact, in the last decades, these resources have been threatened by a degradation of their quality and quantity that furthers natural and anthropic effects, such as climate change, seawater intrusion and overexploitation. However, the protection and management of these resources requires knowledge of the origin of their mineralization. In this study, the Essaouira basin is selected as a typical example. Stable isotopes (18O and 2H) together with geochemical data were used to identify the groundwater salinization origin in the coastal aquifers of the Essaouira basin. The results of both the approaches show that the groundwater mineralization is due to: (1) the dissolution of salt minerals, (2) the ion exchange phenomena, (3) seawater intrusion, and (4) sulphate reduction. Also, the recharge is supported by fast infiltration of oceanic precipitation without significant evaporation.
