Groundwater has been facing not only prolonged climate change-induced groundwater shortage but also severe deterioration of groundwater quality from natural and/or anthropogenic sources. This study aims to determine the hydrogeochemical processes controlling groundwater chemistry in the Saiss basin, Morocco, and to assess seasonal changes in groundwater quality using the entropy-weighted water quality index (EWQI). In addition, human health risks associated with groundwater nitrate (NO3−) contamination/pollution were investigated using the hazard quotient (HQ). Groundwater chemistry in the Saiss basin was mainly controlled by mineral dissolution/precipitation and direct cation exchange, with slight seasonal variations in the saturation indices (SIs). The EWQI suggested slight groundwater quality deterioration in the dry season due to increased NO3− concentrations. In fact, children were over two times exposed to non-carcinogenic issues associated with groundwater NO3− concentrations when compared with adults. The current study provides further insights into the hydrogeochemical characteristics of groundwater to ensure safe regional water supplies. |
