Underground Injection Control

In a cooperative effort between EPA, state and tribal governments, the UIC Program works toward protecting underground sources of drinking water (USDW) from contamination by regulating the construction and operation of injection wells. Underground injection wells are primarily used to dispose of wastes into the subsurface and have the potential to adversely affect USDWs. Five classes of wells are defined according to the type of waste that is disposed and where the waste is injected. Detailed information on regulations can be found at EPA Regulations.

A brief description of the well types:

Class I: Industrial and Municipal Wells that Inject Beneath Lowermost USDW
Class II: Associated with Oil and Gas Production
Class III: Associated with Mineral Recovery
Class IV: Wells Injecting Hazardous Waste into USDWs (prohibited)
Class V: Injection Wells Not Included in Other Classes (typically Shallow Disposal Systems)
