A –Streams of Thought– contribution by Kevin Roche.
In our inaugural Hallway Conversations article we have the pleasure of learning about the most recent AGU Chapman Conference through the eyes of its principal organizer, Jaime Gómez-Hernández (JGH), a professor of hydrogeology from the Universidad Poletécnica de Valencia. Together with the Chapman planning committee, Professor Gómez-Hernández brought researchers from around the world together for a week of presentations, discussions and activities in his native Valencia, Spain. “The MADE Challenge for Groundwater Transport in Highly Heterogeneous Aquifers” highlighted current understanding and future needs to address the growing threat of aquifer contamination. Discussions centered on the Macrodispersion Experiment (MADE) Site, located on the Columbus Air Force Base in Mississippi, USA. Thirty years of experiments and site characterization have made it one of the most intensively-studied aquifers in the world; and although its sampling wells are no longer in place, MADE’s rich datasets are still used to test novel groundwater modeling theory.
