Bill Alley, Director of Science and Technology for the National Ground Water Association and former chief of the the USGS's Office of Groundwater, gave this informative PPT on the Groundwater Visibility Initiative (GVI) during NGWA's recent Groundwater Week:
Here is the GVI paper from Groundwater:
Here is the citation: Alley, William, Lisa Beutler, Michael E. Campana, Sharon B. Megdal, John C. Tracy, 2016. Groundwater Visibility—The Missing Link, Groundwater, 54(6): 758-761.
I've go to put up the last slide from Bill's PPT:
Bruce Babbitt, educated as an Earth scientist before he studied the law, is a great person for a quote. So who are the others? Almost all of them are pretty smart! Yes, I must admit I reviewed both the proposal and the final manuscript for the Yale University Press. Ir's a wonderful book.
From the Amazon.com site:
“There is little information available for general consumption that explains why groundwater is important, how it works and what can be done to solve current problems. This book provides that information in an extremely readable way.”—Mark Giordano, Georgetown’s School of Foreign Service
