Water is an essential resource to us all. We all rely on it, not only for drinking water but also for our homes and industry. Groundwater is becoming scarcer with our changing climate. Locating clean groundwater requires knowledge of the geology, and the basis for that knowledge are geological maps – OneGeology will help make that map data accessible.
