A lack of information on groundwater has historically posed challenges for management. Now emerging tools are expanding and organizing the data available for decision-making, as discussed in this episode with Ben Kerr of Foundry Spatial, Melissa Rohde of The Nature Conservancy, and Tom Gleeson of the University of Victoria. They talk about using technology for groundwater management in Canada and California, how the interaction of surface water and groundwater factors into information gathering, and the benefits of visually appealing interfaces for data.
