Aprašymas

Fresh groundwater in the Mississippi embayment can be found in alternating formations of sand, silt, and clay. The uppermost of these formations is the Mississippi River Valley alluvial aquifer (alluvial aquifer), which can provide well yields of 300 to 2,000 gal/min. The alluvial aquifer exists at land surface and covers much of the embayment area within the Mississippi Alluvial Plain.
