Climate change is already affecting the volume and quality of water that's coming out of many taps in Nova Scotia. Drought, saltwater intrusion, and flooding are just some of the issues that scientists predict will become worse in the coming years for the 42 per cent of Nova Scotians who rely on groundwater from private wells. "With climate change, we will see more extreme events and we will see more impacts on our shallow and even our deep groundwater resources," said Barret Kurylyk, an associate professor at Dalhousie University and Canada Research Chair in Coastal Water Resources.
