Abstract

The majority of Senegal\'s groundwater has a surplus concentration of iron and manganese. The diagnosis of drilling water shows that more than 80% of the water collected in different areas of Senegal have high amount of those both elements. Their concentrations are higher than the WHO guideline value of 0.3 mg. L-1 and 0.05 mg. L-1. While iron and manganese do not pose a serious health risk, their presence may indicate that groundwater is of poor quality and may be indicative of other problems that may have adverse effects on human health. The purpose of this study was therefore to characterize the groundwater of some areas in Senegal and to evaluate the representativity of iron and manganese in terms of concentration in order to provide elements of response to high concentrations in the water. To reach this objective, we applied the Principal Component Analysis (PCA) and Variance Analysis (ANNOVA) method of the MinitabR version 17 software on physical and chemical analysis results in order to better interpret the results. Therefore, the characterization of the samples showed globally that the groundwater must be treated before consumption by the populations. The qualitative study made it possible to highlight that the Maastrichtian is the most exploited tablecloth like the other tablecloths. Thus, this present study has also shown that the groundwater collected in these different regions deserve to be purified before consumption by the populations because the following physical and chemical parameters: electrical conductivity, turbidity, sulphates, iron and manganese far exceed the potability standards accepted by WHO.
