Evaluating the Impacts of Climate Change and Seawater Intrusion on Arsenic Mobilization in Coastal Aquifers

Many rural communities in the maritime Provinces rely on groundwater for drinking water supply. There is concern that the groundwater in these areas may become contaminated with naturally occurring arsenic as the climate changes. Climate change effects including rising sea levels, longer summer droughts, and more intense storms may alter the geochemical conditions in the subsurface and cause arsenic to be released into the groundwater. The objective of this project is to develop and test an advanced numerical model capable of simulating the retention and release of arsenic in coastal aquifers as climate climates. This collaboration between the University of Western Ontario (Canada) and Carl von Ossietzky Universitat Oldenburg (Germany) will combine the strengths of both institutions to develop and test a model that will provide insight into when and where arsenic may become a potential threat for local groundwater supply. The model will help scientists, engineers and policy makers to develop best practices and guide policy changes that protect drinking water and support climate adaptation strategies for coastal communities. This project will strengthen international collaboration between the two universities by enhancing research, training, and knowledge exchange, while promoting long-term international cooperation in climate change adaptation.
