Assessment of the impact of Imzouren city’s WWTP on the quality of the surrounding groundwater, at the Rif Central (Northern Morocco)

The groundwater of the Ghis-Nekor aquifer (Central Rif Morocco) is main water resource used by inhabitants for agricultural and domestic purposes. However, its low quality may affect health consumer weaken production. existence WWTP at level this plain, makes it a probable source pollution these requires urgent managers’ intervention. Groundwater in area be related to natural, anthropogenic undefined sources (agricultural industrial activities). To assess impact effluent on aquifer, ten well samples were collected upstream downstream 2018, then analysed physicochemical quality. Multivariate principal Component Analysis (PCA) results obtained revealed two components, which largest total variation being F1 presented 54.75%. PCA has visualized groups that distinguish slightly mineralized waters moderately from other wells WTTP are highly mineralized. Generally, study characterized high levels salinization. useful monitoring managing area.
