Managing Groundwater Storage
This 1 hour AGI Critical Issues webinar introduced the geoscience of managing groundwater storage and recharge, discussed groundwater storage policies and research in California and Texas, and reviewed case studies and potential future developments.
Groundwater is a critically important source of water in the U.S., supplying fresh water for drinking supplies, agricultural irrigation, and streams, rivers, and ecosystems. However, groundwater is becoming increasingly depleted in most aquifers around the country, with impacts including shrinking aquifer storage capacities, land subsidence (and associated impacts like higher flood risk), and declining freshwater resources for communities and ecosystems. To mitigate and reverse the depletion of groundwater storage in local aquifers, many communities are turning to managed aquifer recharge (MAR) and aquifer storage and recovery (ASR). MAR and ASR practices vary depending on local geology, groundwater and recharge water composition, local land use practices, and water use requirements. Implementing MAR and ASR requires careful planning to both maximize groundwater replenishment and protect groundwater supplies from contamination.
Water storage is water security -and the largest space to store water is underground. This talk by Graham Fogg reviews surface and groundwater storage in California, new opportunities from winter recharge on farms and floodplains, and examples of alternate reservoir and aquifer management. This is the second presentation from the AGI Critical Issues webinar, "Managing Groundwater Storage". This webinar introduces the geoscience of managing groundwater storage and recharge, discusses groundwater storage policies and research in California and Texas, and reviews case studies and potential future developments.
