Potentiometric Surface of the Middendorf Aquifer in South Carolina, November 2001

Brenda L. Hockensmith


The potentiometric surface of the Middendorf aquifer for November 2001 shows that the generally southeastward ground-water flow is affected by several potentiometric lows. These cones of depression have developed because of ground-water pumping in the Florence-Hemingway area, around Mount Pleasant, and around Kiawah Island.

Comparing the November 2001 data with historical data shows that water levels near the outcrop areas of this aquifer have declined as a result of the drought conditions that have persisted in South Carolina since 1998. In areas influenced by pumping, water levels have declined 47 to 267 feet during various periods of record.
