The Essaouira region at the edge of the Moroccan Atlantic Ocean is subject to a semi-arid climate. The decrease in rainfall as a result of climate change and the increase in the exploitation of surface and groundwater have disrupted the stability of these resources and threaten the socio-economic and environmental balance in the area under investigation. Climate scenarios estimate that precipitation will decrease by 10–20% while warming increases by 3 °C over the next 30 years. The physico-chemical parameters studied show that the evolution of the pH and temperature of the groundwater remained stable with a neutral (pH ≈ 7) and a hypothermal character (T < 30 °C). For the electrical conductivity, it showed an increasing trend from 2017 to 2020. A hydrochemical approach showed that the groundwater mineralization was controlled by the dissolution of evapo...

The pollution was evaluated in three different sugar beet soils using enrichment factor (EF), geo-accumulation index (Igeo), contaminant factor (CF), potential contamination index (Cp), and pollution load index (PLI). The obtained results show that the studied agricultural soils were contaminated with various heavy metals and metalloids such as As (<8–34.5 mg kg−1), Ba (186.5–241.0 mg kg−1), B (73.0–103.7 mg kg−1), Co (24.7–34.7 mg kg−1), Ge (10.7–25.7 mg kg−1), Nb (11.5–25.5 mg kg−1), and Mo (32.3–35 5 mg kg−1). The results of EF (99.04–2.60), CF (31.81–1.43) indices showed that these soils are heavily polluted with various elements (Mo> Ge> As>...
