The sustainability of freshwater resources is one of the most important challenges of the Mediterranean region and European Union, constituting a social, economic, and technological challenge, as pressure on these resources is increasing rapidly due to sharp population growth and industrial and agricultural activities. This situation will be especially dramatic in urban areas, which are expected to amass 70% of the world’s population by 2050. Moreover, water resources will be also affected by climate change, especially in the south of Europe, where droughts will be more frequent, intense, and long. Combining both chemical and quantitative status assessments show that 29% of the total groundwater body area lacks sufficient capacity to meet the needs of ecosystems or society. Consequently, it is essential to preserve groundwater resources from overexploitation, but also from anthropogenic pollution.
WATERPOLLUT is focused on the newest classes of contaminants (organic contaminants of emerging concern, microplastics, geogenic trace elements and inorganic elements of emerging concern), investigating their presence, their hydrodynamic behaviour and natural attenuation through modelling and identification of their transformation products in groundwater, and also the potential risk associated with the consumption of drinking water produced from contaminated groundwater. In addition, the project aims at identifying pollution sources of emerging contaminants and at distinguishing between anthropogenic and geogenic origins in case of inorganic pollutants. Studies will be conducted in the deltas of two Mediterranean with distinct characteristics.
WATERPOLLUT will consist of two sub-projects: ATTENUATION and GEOTHROP-H2O, which are executed by two research institutes. the Institute of Environmental Assessment and Water Research (IDAEA) and Desertification Research Centre (CIDE) with recognized expertise in water quality analysis, risk assessment of contaminants in human health and environment, the assessment urban groundwater quality and evaluation of the impact of climate change on freshwater resources. To achieve the demanding objectives of this project, subject matter experts from the fields of analytical chemistry, hydrogeochemistry and numerical modelling will team up to design and execute the project in order to generate meaningful quality results. The need for such multidisciplinarity has been the driver for the collaboration between the two Centers coordinating the two subprojects that constitute the project WATERPOLLUT.
