Discover the potential of using environmental tracers to reduce uncertainty of hydrogeological predictions in all environments, especially highly heterogeneous systems where spatial variations in aquifer hydraulic conductivity may range over several orders of magnitude during the farewell presentation of the 2009 NGWREF Darcy Lecture presented by Dr. Peter G. Cook. Using North American field sites as illustrative examples, the lecture also discusses methods available to you for bridging the gap between research and practice.
