Excerpt: ...Mississippi and southern Tennessee. As shown in figure 1A, most of the Mississippi Alluvial Plain is a predevelopment discharge area for the five studied aquifers. The zone that had the largest predevelopment discharge, also in the northern area, was in the Mississippi Alluvial Plain east of Crowleys Ridge where the upper Claiborne aquifer subcrops the Mississippi River Valley alluvial aquifer. For the majority of this area, discharge to the alluvial aquifer was more than 0.2 in./yr, and in a small area (about 100 mi2) west of Memphis discharge from the upper Claiborne aquifer was more than 0.6 in./yr. Possible explanations for this large recharge and discharge in the northern area are (1) the middle Claiborne aquifer has large transmissivity, (2) the embayment is narrow and thus flow paths from recharge points to discharge points are shorter, and (3) high heads in the aquifer outcrop areas produce correspondingly higher heads in individual aquifers under the Mississippi Alluvial Plain, forcing flow upward into the upper Claiborne aquifer and thence into the Mississippi River Valley alluvial aquifer. Before development, aquifer outcrop areas in the eastern and western areas had more than 0.2 in./yr recharge in the upland areas of central Mississippi, south-central Arkansas, and northwestern Louisiana, but most of the outcrop areas had less than 0.2 in./yr recharge (fig. 1A). Predevelopment discharge from the aquifer system in the eastern and western areas was predominantly to the Mississippi River Valley alluvial aquifer, but some discharge was to large rivers and valleys. The Mississippi River Valley alluvial aquifer, which underlies the Mississippi Alluvial Plain, received as much as 0.2 in./yr discharge from the subcropping aquifers...

Book excerpt: Major Findings: 1) Few contaminants were detected at concentrations greater than human-health benchmarks 2) Groundwater is a source of phosphorus to streams in the lower Mississippi River watershed 3) Nitrate concentrations in shallow groundwater were low despite widespread fertilizer use 4) Groundwater is most vulnerable to contamination where groundwater residence times are short 5) Vulnerability of deep aquifers may increase in areas of high-volume pumping.

This book was released on 2014-07-23 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mississippi River Valley alluvial aquifer is a water-bearing assemblage of gravels and sands that underlies about 32,000 square miles of Arkansas, Kentucky, Louisiana, Missis-sippi, Missouri, and Tennessee. Pumping of groundwater from the alluvial aquifer for agriculture started in the early 1900s in the Grand Prairie area for the irrigation of rice and soybeans. From 1965 to 2005, water use in the alluvial aquifer increased 655 percent. In 2005, 6,242 million gallons per day of water were pumped from the aquifer, primarily for irrigation and fish farming. Water-level declines in the alluvial aquifer were documented as early as 1927. Long-term water-level measure-ments in the alluvial aquifer show an average annual decline of 1 foot per year in some areas.

Book excerpt: The Mississippi Alluvial Plain, a robust agricultural region in the South-Central United States, provides commodities across the United States and around the world. Water for irrigation, which is necessary due to irregular rainfall patterns during the growing season, is withdrawn largely from the Mississippi River Valley Alluvial aquifer, one of the most intensely used aquifers in the United States. The groundwater-dependent region has observed recent declines in groundwater and streamflow levels, raising concerns about the availability and use of fresh-water resources. Declining water levels have prompted investigation into the current understanding of groundwater and surface-water interaction. Previous research does not adequately quantify the unobservable exchange of water between surface-water bodies and the underlying aquifer. This research was designed to advance the current understanding of the interaction between groundwater and surface water through the quantification of spatial and temporal trends in streamflow and groundwater level changes and the use of high-resolution spatial estimates of streambed hydraulic conductivity. Changes in streamflow and groundwater levels were quantified with the use of hydrograph-separation techniques and trend analyses. High-resolution estimates of streambed hydraulic conductivity were found through the correlation of waterborne continuous resistivity profiling data to hydraulic conductivity and streambed hydraulic conductivity estimates were incorporated into the existing Mississippi Embayment Regional Aquifer Study (MERAS) groundwater-flow model. Site-specific empirical relationships between resistivity and hydraulic conductivity were developed with near-stream borehole geophysical logs to improve model estimates of streambed hydraulic conductivity. Results of the quantification of changes in streamflow and groundwater levels suggested agricultural groundwater withdrawals for irrigation to be the primary source of grou
