Analyses Physico-chimiques et Bactériologiques de l’eau de mer (Complexe GP1Z Sonatrach d’Oran, Sablette et port de Mostaganem)

Abstract

The sea has always been considered as a universal receptacle for all forms of pollution generated by human activities which have systematically resulted in physico-chemical and bacterial pollution on the coastline, thuscreating an ecological imbalance and pathogenic and epidermal manifestations. The objective of our workis to assess the physico-chemical quality of bathing water to protect human health. We assess the quality of sea water (Sablette, Port of Mostaganem and Arzew littorale GP1Z complex) and common releases GP1Z complex (WWT ph1, WWT ph2, RC), while performing the analysis of the physic-chemical parameters( PH, T °, Conductivity, MES, BOD5, DCO, Total hardness TH, [Ca2 +], [Mg2 +]) and microbiological parameters (Total germs, Total coliforms, E. Coli, Clostridium, and Fecal streptococci). The physico-chemical analyzes show that this analyzed sea wateris in Algerian standards, and for bacteriological analyzes show that most of the water is polluted and needs solutions to reduces a water pollution.
