Evaluation et cartographie de la vulnérabilité à la pollution des eaux souterraines, selon les méthodes drastic et god, dans la plaine alluviale de guelma, Nord-Est Algérien

الملخص EN

Summary This study deals with the vulnerability and pollution risk in the Guelma plain aquifer (Algeria).

The plain has been threatened by numerous pollution sources (urbanization, industry, farms, dumps, etc.) which have unfortunately increased in the area, due to a lack of environmental protection measures, especially for water resources.

A map of vulnerability of groundwaters of the zone was carried out according to two methods (GOD and DRASTIC).

The obtained vulnerability map shows three zones of differing vulnerability degrees: areas of low and medium vulnerability which respectively occupy 25 and 30% of the total area of the plain, while high vulnerability areas occupy 40% by method GOD and covers the remaining 45%by method DRASTIC of the study area.
