The National Science Foundation (NSF) has awarded funding to the Kentucky Geological Survey (KGS) at the University of Kentucky to lead a team of collaborative researchers from UK, the University of Arizona and the University of Iowa in an innovative project to study groundwater flow in karst aquifers. Karst aquifers are characterized by rapid, turbulent flow of groundwater through complex underground networks of fractures and solution conduits (caves).
These aquifers are present in many parts of the world underlain by soluble rocks and provide drinking water for millions of people. In Kentucky, where such carbonate rocks as limestone underlay more than 50% of the state, karst aquifers are used for public and private water supplies. They contribute substantially to the flow in many surface
