Remedial Action Sites in Arizona

Remedial Action Sites are contaminant sites in Arizona being investigated and remediated under the following Arizona and federal environmental programs:


 rain drop  Water Quality Assurance Revolving Fund (WQARF; including mitigation of non-hazardous releases)

 rain drop  Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, also know as Superfund)

 rain drop  U.S. Department of Defense (DOD) Installation Remediation Program (IRP)

 rain drop  Arizona Leaking Underground Storage Tank (LUST) program

 rain drop  Arizona Voluntary Remediation Program (VRP)

 rain drop  Arizona Hazardous Water Program (Resource Conservation and Recovery Act, RCRA)

 Buffer zones around remedial action sites have been prescribed by state statute and rule to delineate the entire boundaries within which additional technical review of Notices of Intent to Drill and Well Permits is required by ADWR.  The statute and rule prescribes a one-mile buffer around WQARF, CERCLA, and DOD IRP sites, a one-half mile buffer around VRP and RCRA sites, and a 500 feet buffer around LUST sites.
