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.

Abstract: (french)
Dans le but de déterminer la qualité physico-chimique des eaux souterraines du Pré-rif de la région de Taza, en mettant l’accent sur les fluorures. Cette étude a intégré une caractérisation physico-chimique de ces eaux, portant sur 17 paramètres y compris les ions fluorures. Les résultats obtenus ont révélé que les eaux étudiées sont de très mauvaise qualité dans 46,6% des points, avec un caractère alcalin, sous oxygénées dans 40% des points, et des teneurs en orthophosphate hors des normes recommandées dans 86,6% des échantillons. Un caractère hyper-fluoré a été, également, dévoilé dans 73% des eaux étudiées (1,52-5,90 mg/L), avec certaines teneurs qui égales de 2 à 4 fois la valeur guide (<1,5 mg/L). Un traitement des données par l’Analyse en Composante Principale a été réalisé et les résultats de cette analyse ont permis de mettre en évidence certaines tendances.
