Under these conditions, aquifers are in a situation of over-exploitation with pumped volumes far exceeding natural recharge rates. In recent decades, there has been a significant increase in water demand due to local population growth and agricultural development. In the Algerian Sahara known for its arid climate, groundwater is the main source of water used mainly for domestic and irrigation practices in the area. Were suitable for drinking and irrigation with a high quality of water located Quality indices (WQI) that have been mapped reveal that the groundwater samples Chemical analyses of theĪlbian groundwater in the study area show the dominance of evaporite facies (Cl - Na + - Ca 2+ ) with lowĬoncentrations than the Algerian Standards for Drinking (ASD). Region and especially around the major cities (Gharda ïa, Berriane, Metlili and Zelfana) with more than 8 meters. Water-level-change map showed a significant drop in the groundwater level over Thematic maps were gridded using Geostatistical tools of ArcGIS software. The application of geostatistics by kriging and the steps of analysis, modelling and calculation of semivariogram haveĮnabled us to draw up maps of the various hydrogeological and hydrochemical parameters. The objective of our study is to know the current state of thisĪquifer, while studying the variation of its piezometry for the period 2010 - 2018, and also the chemical quality of its groundwater byĮntire study area. This requires periodic monitoring and control of its piezometric level Its supply is very low, so it is a very low renewable This aquifer is heavily exploited by a very

Growing needs of drinking water supply, agriculture and industry. Groundwater resources are considered the only source available to meet the In our study area, the CI is identified, as a regional subset, as the Albian Aquifer of M ’ zab Region (AAMR). The Albian Aquifer, commonly called Continental Intercalary (CI), main component of North Western Sahara Aquifer System (NWSAS/SASS), constitutes the mostĮxtensive aquifer formation of the region. The M’zab region is subject to an arid SaharanĬlimate where surface and sub-surface waters are of little importance.
