Underground Injection Control (Oil and Gas) Law and Legal Definition

Underground Injection Control is a program required in each state by a provision of the Safe Drinking Water Act (SDWA) for the regulation of Injection Wells, including a permit system. An applicant must demonstrate that the well has no reasonable chance of adversely affecting the quality of an underground source of drinking water before a permit is issued. An injection well is a vertical pipe in the ground into which water, other liquids, or gases are pumped or allowed to flow.
