Groundwater Protection Unit :: Groundwater Remediation

The Aquifer Protection Section issues different permits for the remediation of contaminated groundwater, depending if the contaminated groundwater is extracted prior to treatment or if it is treated in place.

IN SITU GROUNDWATER REMEDIATION
Groundwater remediation strategies that use wells to introduce substances into the subsurface to neutralize, oxidize, reduce, or otherwise destroy groundwater contaminants are regulated by the Underground Injection Control Program.

NON-DISCHARGE GROUNDWATER REMEDIATION
The groundwater remediation portion of the Non-discharge Permitting Program regulates groundwater remediation systems that extract and treat contaminated groundwater. When groundwater is withdrawn from the subsurface it must be disposed of in accordance with state statute and rule. NC General Statute 143-215.1 requires that wastewater, which includes contaminated and treated groundwater, be disposed of with the appropriate permit(s). A Groundwater Remediation Permit Application must be submitted prior to disposal.

Contaminated soil is often associated with groundwater contamination. Soil remediation is an important measure for eliminating sources of groundwater contamination. A permit application must be submitted for all soil remediation activities.

NEW policy and guidance regarding hydrogeologic investigations related to groundwater remediation projects has been crafted to aid consultants preparing applications and DWQ review staff. See the following documents for more information:
