ANALYSE STATISTIQUE ET GEOCHIMIQUE DE LA DYNAMIQUE DES PARAMETRES PHYSICO-CHIMIQUES DES EAUX SOUTERRAINES DU SYNCLINAL DE GHASSIRA ALGERIE ORIENTALE
This paper is about groundwater’s quality in Ghassira which is located in El-Abiod valley in eastern Algeria. The water is used for human consumption and irrigation. The different layers belong to several types of rocks (limestone and evaporate ...). To study the behaviour of dissolved salts in this water, we have used geology of the aquifers and statistics. This combination gives us information about minerals those are responsible of water’s quality. 80% of analyzed samples are influenced by evaporate rocks (gypsum, halite…) and 20% by limestone. Many processes have generated these two classes and are relating, especially, with the rocks of aquifers.
