Injection Closed-Loop Groundwater Remediation Wells (non-discharge type remediation)

Non-discharge groundwater remediation systems are groundwater treatment systems that extract and treat contaminated groundwater. These include closed-loop groundwater remediation systems and typically use infiltration galleries or injection wells. This type of groundwater remediation system, which withdraws, treats, and then re-injects treated groundwater back into the aquifer, is permitted per 15A NCAC 02C .0225 (b).


Please note that fees have been increased effective July 1, 2023. North Carolina’s 2023 Appropriations Act Session Law 2023-134 included fee adjustments for 28 Department of Environmental Quality (DEQ) programs to support the delivery of services and state employee salaries. This is the first fee increase in 16 years for most of these programs.
