Environmental remediation is the process of removing contaminants from soil, sediment, groundwater, and surface water. Environmental remediation can generally be categorized as in-situ or ex-situ. In-situ involves treatment without soil excavation, while ex-situ means treatment of the surface after soil excavation.

A site assessment usually precedes the remediation process. Guidelines are available from the US Environmental Protection Agency on how to proceed with treatment. The agency also imposes sanctions in cases where the treatment process is delayed or otherwise obstructed.
