The objective of this study is to determine the physicochemical quality of the groundwater of the pre-rif of Taza region, with emphasis on fluorides. This study integrated a physicochemical characterization of these waters, covering 17 parameters including fluoride ions.
The results showed that the waters studied are of very poor quality in 46.6% of the points, with an alkaline character, under oxygen in 40% of the points, and orthophosphate contents outside the recommended norms in 86.6% of the samples. A hyper-fluorinated character was also revealed in 73% of the waters studied (1.52-5.90 mg / L), with certain levels equal to 2 to 4 times the guideline value (<1.5 mg / L).
Data processing by the Principal Component Analysis was carried out and the results of this analysis made it possible to highlight certain trends.
