摘　　要：The study area is a semi-arid area located in the Arlit region.This area contains significant uranium deposits that have been mined by two mining companies since 1968.The objective of this study is to determine the impact of these activities on existing aquifers,in particular Izegouande aquifer.A methodological approach based on hydrochemical methods focusing on the analysis of nitrates and sulfates showed that waters of Izegouande aquifer have high nitrate concentrations ranging from 16 mg/L to 60 mg/L,higher than WHO(World Health Organization)standards drinking water.In addition,these waters show elevated sulfate levels ranging from 16 mg/L to 57 mg/L,therefore acceptable.These high concentrations of nitrates and sulfates are located mainly near wastewater treatment of Arlit city and near industrial zone,which are potential areas for transfer of these elements such as nitrates and sulfates.It is therefore urgent to carry out periodic and regular checks on groundwater in these areas.
