CONTRIBUTION TO THE CHARACTERISATION OF THE PHYSICO CHEMICAL QUALITY OF WATER OF SOME SPRINGS IN THE REGION OF TANGIER-TETOUAN (MOROCCO)

Abstract

Our study, based on the grid water quality World Health Organization (WHO, 2004), targeted the evaluation of the physico-chemistry and heavy metals of water springs of the Tangier- Tetouan region (North-western Morocco). The analyses have involved eleven springs with tap water treated for three companies. According to Rodier (1978, 2009), the samples were taken from March/2013 to June/2013. The results for physico-chemical analysis have shown that the region has generally good quality of water, with the exception of a single spring (Agla), which itself shows a high contamination of iron and manganese. As for the heavy metals, it was found that all springs have very low concentrations or no trace elements. So general, the evaluation of the results of physico-chemical analysis presented in this work can be considered eligible and have no impact on the quality of the water, these results are consistent with those obtained by Belghiti et al.
