IMPACT OF SEASONAL VARIATION ON FLUORIDE IONS CONCENTRATIONS IN GROUNDWATER IN THE MARADI REGION (CENTRAL NIGER)

The present study aims to study the impact of seasonal variation on fluoride ion concentrations in groundwater in the Maradi region. To achieve this goal, two (2) water sampling campaigns were carried out.Sampling was carried out over the entire study area. Water samples were taken from wells and boreholes.The results of this study show that the high levels of fluoride ions are obtained during the rainy season likewise, this content of fluoride ions vary according to the variation of certain ions.
