How Long Will Our Aquifers Last? Online
May 22 6:00 pm
Robert Mace, Executive Director and Chief Water Policy Officer, The Meadows Center for Water and the Environment, & Professor of Practice, Dept. of Geography and Environmental Studies, Texas State University
Groundwater is, as famously quoted by the Texas Supreme Court in 1904, “secret, occult, and concealed.” Sometimes referred to as “hidden water,” it is out of sight and, therefore, unfortunately, out of mind. However, groundwater comprises 98.7 percent of all the fresh, unfrozen water on Earth. About 40 percent of all surface-water flows in the United States are sourced from innumerable seeps and springs that discharge groundwater into streams and rivers. Groundwater supports 26 percent of the human use of water with 70 percent of it watering crops. As drier areas become drier and droughts increase everywhere, groundwater is expected to make up the difference. Unfortunately, much of the groundwater used across the planet is produced unsustainably. This unsustainable use affects flows to springs, streams, rivers, wetlands, and estuaries that support ecologies as well as human needs. In some cases, such as in the Houston area, groundwater production has caused the land to sink, increasing flooding. In this presentation, Professor Mace will present what he has learned about groundwater sustainability through a report he published late last year title “Five Gallons in a Ten-Gallon Hat: Groundwater Sustainability in Texas” and in a forthcoming book titled “Groundwater Sustainability: Its Birth, Development, and Application.” Listeners will have a better understanding of what groundwater sustainability is, how Texas and the greater Houston area is doing with sustainable groundwater management, and what people can do to achieve groundwater sustainability. Time for interactive discussion with the speaker will be provided.
