Forty-one observation wells and tow stratigraphic test holes were drilled near the Shelby County landfill in east Memphis. These wells were installed as part of an investigation on possible vertical leakage of ground water from the shallow aquifer into the Memphis Sand aquifer. The shallow aquifer consists of about 45 to 55 feet of alluvial silt, sand, and gravel. This is separated for underlying Memphis Sand aquifer by about 30 to 60 feet of silt, silty sand, and clay in the confining layer. Thirty wells completed in the alluvium were generally less than 50 feet deep. The to the water table ranged from about 15 to more than 45 feet below land surface. four observation wells were completed in the upper part of the Memphis Sand at two sites. Water levels in the Memphis Sand were generally 35 to 40 feet below land surface. |
