CAESER concluded that a connection exists between a shallow aquifer and the Memphis Sand aquifer in what is known as the Davis wellfield. That wellfield is one of several stations where MLGW pumps the area s drinking water out of the Memphis Sand aquifer. A hydrologic connection between the Horn Lake Cutoff channel and MRVA [shallow] aquifer exists and creates a pathway for runoff from the TVA Allen Former Fossil Fuel Plant to affect the water quality of the Davis wellfield, CAESER s report concluded.
TVA disputed that surface water runs along with the Horn Lake cutoff from the Allen Fossil Plant and its two coal ash ponds to the Davis wellfield. The Horn Lake cutoff is a stream that runs from T.O. Fuller State Park to the Davis Wellfield.
