Mississippi Embayment Regional Aquifer Study
The US Geological Survey (USGS) is conducting large scale multidisciplinary regional studies of groundwater availability for the Nation. Studies comprise individual assessments, like the Mississippi embayment, of regional groundwater flow systems that cover a variety of hydrogeologic terrains and are used to develop a comprehensive regional and national perspective. Collectively, these individual studies are the foundation for the national assessment of groundwater availability. Availability studies are conducted in cooperation with other Federal, State, and local governments and the private sector, involved computer-based groundwater flow models to document effects of human activities and climate variability on groundwater levels, depletion, storage, and interaction with surface water.
