Dr Sarah Bourke: World Water Day

March 22 is World Water Day. Supported by the United Nations this year’s theme is called Groundwater: Making the invisible visible.

It’s an extremely relevant topic here in Perth, where 50% of the city’s drinking water comes from groundwater. Dr Sarah Bourke, a groundwater hydrologist at UWA joins Tom Reynolds to talk about Perth’s groundwater, where it comes from and what exactly we’re drinking.
