Groundwater salinization in a coastal multilayer aquifer: Preliminary results on origins and mechanisms. Example of Recife (Brazil)
Abstract
The Recife Metropolitan Region (PE, Brazil) appears as a typical "hot spot" illustrating the problems of southern countries such as urbanization or rapid industrial and touristic development. All these factors induce high pressures on water resources both on quantity and quality in the context of global social and environmental changes. This paper focuses on the groundwater geochemistry in a costal multilayer aquifer aiming at investigating the sources and processes of salinization. The preliminary results of 62 groundwater samples from the five main aquifers are reported.
