Recherche de l’impact des fosses septiques sur les caractéristiques physico- chimiques des eaux de la nappe phréatique de la région de Ghardaïa (cas de Sebseb).

Abstract

The groundwater resources in the Saharan regions are the only source of water and determine the existence of life in these regions. This study was conducted at four sites in the region Sebseb with physico-chemical characterization of three pits and 21 wells with a witness. Analyzed waters are used by local people in irrigation and even consumption The results showed that the degradation of the physico-chemical quality of the water table with a clear impact septic systems. The degree of contamination varies from one site to another depending on the distance and / or elevation of wells compared to the pits. Wastewater septic proves quite generally carry pollutants and are a real threat to the environment of the region, particularly for groundwater.
