| Summary: | This study of groundwater pollution was carried out near extractive industries in the Thiès region, more precisely in the Tivaouane department of Senegal. In this area, phosphate rock mining began in 1960 and phosphoric acid production began in 1984. The objective of the study is to analyse the impact of extractive industries on groundwater. Specifically, the aim was to determine the degrees of pollution of the aquifer with any form of contaminant introduced by the extractive industries in the communes of Darou Khoudoss, Taïba Ndiaye, Mboro, Méouane, Pire Goureye, Tivaouane and Chérif. The methodology used is based on observation, interviews and documentary analysis. The study aims to highlight the problems related to groundwater pollution and access to drinking water in localities located in the vicinity of extractive industries. Thus, it has been highlighted that the causes of the problem of access to and management of water resources in the area are linked to the use of the volume of water by the extractive industries. Indeed, the use of chemicals (fuel, sulphur, fuel oil, diesel, toluene, silica, sulphur, etc.) by industry has led to the acidity of the water and has generated the drying up of village wells. As a result, water quality, an important part of this problem, does not meet the standardised standards of the WHO, and in some plants it far exceeds the standards of drinkability (water laden with mineral or alkaline salts). However, strategies are being implemented by the extractive industry to address the problem of access to and management of water resources in the study area. |
