Abstract

The Allen Well Field is a municipal well field located in the southwestern portion of Shelby County, in Memphis, Tn that provides drinking water, pumped from the Memphis aquifer, to the City of Memphis. Past research has identified windows in the upper Claiborne confining unit that provide avenues for leakage of modern water from the shallow aquifer system into the Memphis aquifer. 3H-3He data show that young water (less than 50 yrs) is present in three wells in the Allen Well Field. Two of the three wells contain waters with higher total dissolved solids and water compositions similar to those of the Mississippi River water. One well, MLGW 114, contains waters similar in composition to the Fluvial-terrace Aquifer beneath the Memphis Depot. Water levels in the Fluvial-terrace Aquifer indicate a depression in the northeastern edge of the Allen Well Field near the Memphis Depot, and represents an area of possible hydraulic connection between the Fluvial-terrace and Memphis aquifers.
