ETUDE DE LA QUALITE PHYSICO-CHIMIQUE ET BACTERIOLOGIQUE DES EAUX DE LA SOURCE AIN SALAMA-JERRI (REGION DE MEKNES –MAROC)

Abstract

The water is threatened nowadays by pollution of the fact then of a similar degradation of the water resources knowledge of water quality is a paramount condition allowing the introduction of a management system which will contribute to guarantee the water provision in the future. The objective of our work is to determine and quantify the mineral and bacterial pollution of the source Ain Salama, accessible from the regional road R 701 connecting Meknes to Oulmes and the provincial roads P 7064. This study planned to carry out physicochemical and bacterial analysis in order to characterize the medium (underground spring water) and to highlight the parameters which determine water quality namely: Conductivity; the temperature; pH; the cations (calcium, magnesium, potassium and sodium); the anions (chloride, sulfate, nitrate and bicarbonate); elements of traces (Iron, Manganese, Fluoride…); … etc The results showed that the majority of physicochemical parameters meet the standards (Moroccan standards-MS-03.07.001/2006). For bacteriological analysis, they show the absence of most of the pathogens.
