Groundwater pollution is becoming more and more important and concerns about its use for food represent a health hazard .In view of this degradation of the quality of these waters, we proposed to conduct a study to evaluate the physico-chemical quality of the waters of twenty-one representative wells located in the Sidi Taibi region. The latter is known for its important agricultural potential exploiting these underground waters of the Maâmora aquifer. Objectives: The objective of this study was to evaluate the physical and chemical quality of groundwater including twenty-one representative wells in the rural commune of Sidi Taibi (province of Kénitra) during a sampling campaign in 2015. Methods: The physical parameters, in situ and laboratory measurements allowed to characterize the groundwater enveloping Sidi Taibi. SO, facts of pH, temperature, electrical conductivity by integrated mobile hardware measurements and analysis of non-type HANNA pH-meter (HI98150) thermometer and connectivity (HI9033), so that the parameters of other analyzes were carried out within the Radiation Laboratory of the National Center for Energy, Nuclear Measurement Science and Technology. The statistical analysis of the results obtained is based on the comparison of the averages of the various parameters measured. We used maxima and minima to evaluate changes in these parameters for selected sites and for well-defined periods. We also carried out a principal component analysis of the different values obtained through the XLStat software (2014), in order to highlight the possible relationships between the evolution of the parameters. Results: The results obtained show that most of the physicochemical parameters involved in determining the quality of these waters comply with the standards of Morocco and those of the WHO . However, we obtained non-conformance values for ammonium analysis, complete alkalimetric titer and turbidity. These parameters can be considered as indicators of the degree of pollution of this groundwater originating from the domestic and agricultural activities of the population of the region. Conclusions: In the light of these results, as well as those described above, we advocate continuous monitoring of the parameters studied for wells with abnormal values, in particular P16, until the competent authorities connect the villages Region of Sidi Taibi to the drinking water network and the sewerage network. Also, a campaign to sensitize the population on the basic means and techniques of treatment of water intended for human consumption.
