Quality of shallow ground water in recently developed residential and commercial areas, Memphis vicinity, Tennessee, 1997 Quality of shallow ground water in recently developed residential and commercial areas, Memphis vicinity, Tennessee, 1997
Twenty-four monitor wells screened in the shallow water-table aquifer and eight monitor wells screened in the upper part of the Memphis aquifer in the Memphis vicinity, Tennessee, were sampled as part of the Mississippi Embayment National Water-Quality Assessment Program. These samples were collected during April and May 1997, and were analyzed for turbidity, water temperature, pH...

Altitude of the top of the Sparta Sand and Memphis Sand in three areas of Arkansas Altitude of the top of the Sparta Sand and Memphis Sand in three areas of Arkansas
The Sparta Sand and Memphis Sand form the second most productive aquifer in Arkansas. The Sparta Sand and Memphis Sand range in thick- ness from 0 to 900 feet, consisting of fine- to medium-grained sands interbedded with layers of silt, clay, shale, and minor amounts of lignite. Within the three areas of interest, the top surface of the Sparta Sand and Memphis Sand dips regionally east...

Thickness of the Mississippi River Valley confining unit, eastern Arkansas Thickness of the Mississippi River Valley confining unit, eastern Arkansas
Concern arose in the late 1980s over the vulnerability of the Mississippi Valley alluvial aquifer to contamination from potential surface sources related to pesticide or fertilizer use, industrial activity, landfills, or livestock operations. In 1990 a study was begun to locate areas in Arkansas where the groundwater flow system is susceptible to contamination by surface contaminants. As...
