Low-permeability bedrock definition
Low-permeability bedrock means that portion of geologic material between the lower aquifer and upper aquifer that does not readily transmit water in sufficient quantities to supply a well. The Northview Formation, the Chattanooga Shale, and the upper thirty feet (30') of the Cotter Dolomite shall consti- tute the low-permeability bedrock. The low- permeability bedrock serves as a natural bar- rier to groundwater mixing between the upper aquifer and lower aquifer. See Figure 7A included herein for an illustration of geol- ogy in Special Area 2.
