Introduction

The Memphis and Fort Pillow aquifers are the principal sources of water for municipal, industrial, and 

commercial uses in the Memphis area. About 207 million gallons per day (Mgal/d) of groundwater were withdrawn 

in Shelby County, Tennessee, from both aquifers in 2010 for these uses (Maupin and others, 2014), with most of 

the water coming from the Memphis aquifer. The U.S. Geological Survey (USGS), in cooperation with the City 

of Memphis, Memphis Light, Gas and Water Division, collects groundwater-level data in the Memphis area and 

periodically prepares potentiometric-surface maps for the Memphis aquifer to assess conditions in this regionally 

important water supply aquifer. This report presents the altitudes of the potentiometric surface of water in wells 

screened in the Memphis aquifer based on water-level measurements made in the fall of 2000, 2005, 2010, and 

2015 and describes historical water-level changes in the Memphis aquifer at key observation wells in the Memphis 

area. The Memphis area is about 1,500 square miles (mi2) and includes all of Shelby County and parts of Tipton and 

Fayette Counties in Tennessee, parts of DeSoto and Marshall Counties in Mississippi, and part of Crittenden County 

in Arkansas (fig. 1).

Memphis Aquifer

Kingsbury and Parks (1993) described the geology of the study area. The Memphis area lies within the 

Mississippi embayment, a broad structural syncline that plunges southward with its axis roughly coincident with 

the Mississippi River. The embayment contains several thousand feet of unconsolidated Cretaceous and Tertiary 

sediments that dip gently westward and thicken in the down-dip direction. The Tertiary-age (middle Eocene) 

Memphis Sand is a thick layer of sand with lenses of clay and silt and minor amounts of lignite present at various

Monthly water level, in feet above National Geodetic Vertical Datum of 1929

stratigraphic horizons. The Memphis Sand is present in the subsurface throughout the Memphis area and ranges from 

about 650 to 900 feet (ft) in thickness. 

The Memphis Sand constitutes the Memphis aquifer. Confining clay beds above and below the aquifer create 

artesian conditions within the aquifer in much of the Memphis area; however, several studies have identified areas 

where the overlying Jackson-upper Claiborne confining unit is thin or absent (Graham and Parks, 1986; Parks, 

1990; Bradley, 1991; Parks and others, 1995). Recharge to the Memphis aquifer from infiltration of rainfall occurs 

primarily east of the eastern limit of the Jackson-upper Claiborne confining unit (fig. 1), but some recharge occurs 

locally where the confining unit is thin or absent. 

Potentiometric-Surface Maps 

Four potentiometric-surface maps for the Memphis aquifer (figs. 1–4) were prepared using water-level 

measurements made in about 60 wells during the fall of 2000, 2005, 2010, and 2015 in the Memphis area (table 1). 

Generally, the same wells or nearby, alternate wells are measured as part of this water-level network. Access to some 

of the wells was not possible every year, however, and over time some of the network wells have been abandoned 

and filled, resulting in some areas not having water-level measurements. Most of the measurements were made each 

year within about a 4-week period between late September to early November (table 1) when water levels usually are 

near their lowest for the year. Therefore, the potentiometric-surface maps represent low water-level conditions in the 

aquifer for these years. The water-level data used as control points are available through the USGS National Water 

Information System web interface (USGS, 2017a). 

Prior to the onset of groundwater withdrawals from the Memphis aquifer in 1886, the potentiometric surface 

is interpreted to have been a smooth surface with a gentle downward slope to the west-northwest (Criner and Parks, 

1976). Long-term water withdrawals from the aquifer since 1886 have created a large cone of depression in the 

potentiometric surface, and several smaller cones of depression exist within the cone at municipal well fields in the 

Memphis area (figs. 1–4). The general direction of groundwater flow in the Memphis area is toward the center of the 

cone of depression in the Memphis aquifer located near the Mallory well field. 

The shapes of the potentiometric surfaces from 2000 to 2015 are similar, but the altitude of water levels has 

changed in some parts of the Memphis area. Water levels have risen almost 30 ft from 2000 to 2015 in the center of 

the cone of the depression (figs. 1 and 4). Locally, in 2015, water levels were 20 ft higher at the Mallory, Morton, 

and Sheahan well fields and about 30 ft higher at the Allen well field than they were in 2000. Groundwater levels 

east of the McCord and Lichterman well fields have not shown consistent increasing or decreasing trends from 2000 

to 2015. 

Historical Water-Level Changes

Hydrographs for selected wells show the varying degree to which long-term withdrawals from the Memphis 

aquifer have affected water levels in the Memphis area (fig. 5). Water levels measured in wells within the large 

cone of depression in the potentiometric surface have declined substantially compared to those in wells in outlying 

areas, where smaller water-level declines have occurred. Because of the confined conditions of the Memphis aquifer 

throughout much of the Memphis area, the seasonal fluctuation in water levels recorded in these observation wells 

is primarily a result of seasonal differences in water use and pumping, rather than changes in aquifer response 

to seasonal recharge. The increases in water levels at the center of the cone of depression reflect changes in 

withdrawals from the Memphis aquifer, particularly at the well fields near the center of the cone. From 2000 to 

2015, the average daily withdrawals for Shelby County decreased from about 188 to 142 Mgal/d (Dieter and others, 

2017; USGS, 2017b). Water use in 2005 was 187 Mgal/d, which was similar to water use in 2000, but water use 

decreased to 173 Mgal/d in 2010 (USGS, 2017b). Water-level data for the long-term observation wells can be accessed 

at the Memphis area groundwater-level network web page (USGS, 2017c).

Water levels in well Fa:R-002, located outside and northeast of the cone of depression (fig. 5), have declined 

from about 38 ft below land surface in 1949 to a maximum low water level of about 44 ft below land surface during 

2012. After an initial decline in about 1953, water levels were relatively stable between about 1955 and 2000, with 

an average water level of about 40.5 ft below land surface. Since 2000, the average water level has been about 41.5 ft 

below land surface. The relatively recent decline (since about 2010) in water levels likely is the result of increases in 

groundwater withdrawals for irrigation near this well rather than withdrawals in the Memphis area.

Well Sh:Q-001 is located between well Fa:R-002 and the center of the cone of depression. Water levels in well 

Sh:Q-001 declined about 35 ft between 1940 and 2015 (fig. 5). The rate at which water levels were declining began to 

slow down in about 2002, with little to no additional long-term declines since that time.

Water levels near the center of the cone of depression in well Sh:P-076 declined about 70 ft from 1929 to 1975 

(fig. 1). Between 1975 and 1995, water levels in this well did not decline and subsequently began a recovery of about 

30 ft such that the net decline over the period of record is about 40 ft. Because of the age of this well, there is some 

question about the connection of the well screen to the Memphis aquifer and whether the water level in the well may 

be somewhat higher than the water level in the aquifer because of leakage of groundwater from shallower zones 

through the well casing. However, water levels at another observation well, Sh:O-212, at the Mallory well field also 

have risen by 30 to 40 ft over the same timeframe (USGS, 2017c).

Water-level data for wells located north (Sh:O-001) and south (Sh:J-001) of the center of the cone of depression 

indicate that water levels stabilized in the areas near these wells and that the cone has not expanded to the north and 

south. Water levels in well Sh:O-001 have not declined substantially since 1990, and water levels in well Sh:J-001 

have not declined since about 2000 (fig. 5). At both wells, it appears that water levels have recovered somewhat from 

their period-of-record lows.
