Analytical Expressions of Radiocarbon Distribution in Transient State Unconfined Aquifers and Their Application to Determination of Past and Present Recharges of North Africa Aquifers

“…Out of the 184 radiocarbon data published on the NWSAS and Djeffara Aquifer (Gonfiantini et al., 1974; Guendouz et al., 2003; Hadj Ammar, 2016; Hadj Ammar et al., 2014, 2020; OSS, 2003; Petersen et al., 2018; Srdoč et al., 1982; Zouari et al., 2011), only 25 were retained according to our selection criteria (see location of the samples in Figure 1 and Table 1).…”

Geochemical, Natural Radiogenic and Isotopic Implications for Nubian Sandstone Groundwater Assessment in Kharga Oasis, Western Desert, Egypt

“…Additionally, Sherif and Sturchio (2021) reported that the natural radioactivity of the NSA impairs groundwater quality and threatens health risks for adults and infants. The concentration and mobility of radioactive elements in groundwater depend mainly on the residence time between the aquifer matrix, groundwater flow path, redox potential, and mixing with different waters (Divers et al, 2014 andAmmar et al, 2020). The NSA is a multi-layered aquifer where each layer has unique geochemical characteristics and a dynamic flow system.…”
