Lithology injection/confining-zone

Injection/Confining-Zone Lithology and Chemistry provides information on the geology and chemistry of the injection zone formation fluids. 

This section provides information on the range of environmental conditions that occur in deep-well-injection zones in different geologic regions of the U.S. The section on lithology discusses the types of sedimentary formations that are suitable for deep-well injection and confining layers and provides some information on geologic formations that are used for deep-well injection of wastes. The section on brine chemistry discusses the typical range of chemical characteristics of formation waters found in injection zones.
