The Underground Injection Control (UIC) Program, authorized by the Safe Drinking Water Act, is designed to prevent ground water contamination from injection wells. Most injection wells in the Pacific Northwest and Alaska are relatively simple devices used to emplace fluids into the shallow subsurface under the force of gravity. Examples include sumps, drywells, and drainfields. The threat posed to ground water quality varies markedly, and depends mostly upon the volume and nature of the fluids injected, well construction, and the hydrogeologic setting. The federal UIC regulations and additional state requirements are based upon a protective performance standard.
