"Addendum to Policy for "Close Out Procedures for National Priorities List Sites," December 6, 2005.
OSWER Directive OSWER 9320.2-13, 4p.
Available on-line from OSWER PDF (4 pp, 264K)

This document provides an addendum to the OSWER guidance entitled: Close Out Procedures for National Priorities List Sites, EPA 540-R-98-016, OSWER Directive 9320.2-09A-P, January 2000. This memorandum clarifies the criteria Regions should use to evaluate site-wide construction completion for in-situ ground water restoration remedies at Superfund sites, for purposes of that guidance.

"Promotion of Innovative Technologies in Waste Management Programs," April 29, 1996.
OSWER Policy Directive 9380.0-25, EPA publication EPA 542-F-96-012, 7p.
Available on-line from OSWER PDF(7 pp, 20K)

This directive describes EPA initiatives to facilitate the testing, demonstration, and use of innovative cleanup and field measurement technologies and stresses EPA's commitment to promoting environmental technology development and commercialization.

"Guidance for Implementing Superfund Reform Initiative 9a: Risk Sharing," March 24, 1998.
OSWER Directive 9010.02,
Available on-line from OSWER
Cover memo: (HTML) Exit EPA Disclaimer
Directive: (HTML)Exit EPA Disclaimer

This guidance was developed to support implementation of Superfund Reform Initiative 9a: Risk Sharing. Under this initiative, EPA agrees to share the risk of implementing innovative remediation technologies which have potential for improved performance and reduced costs.

For technical resources concerning in-situ and innovative technologies for ground water cleanup, see the following web sites:

CLU-IN: EPA's Hazardous Waste Cleanup Information Exit EPA Disclaimer

This web site provides a comprehensive source of on-line and downloadable information about site remediation and field analytical technologies, including those pertaining to ground water, developed by EPA's Technology Innovation Office. In addition, users may subscribe on-line to a list server that e-mails subscribers monthly announcements of recent documents, training, and conferences related to site assessment and remediation. The website is updated daily with information of value to technology users, developers, and providers. Also available from the EPA's Technical Support Project is Ground Water Forum Web Site which contains publications on various ground water issues developed by a network of EPA Remedial Project Managers, Corrective Action Staff, and On-Scene Coordinators together with EPA's research scientists.

FRTR: Federal Remediation Technologies Roundtable

This web site was developed by a consortium of EPA and 6 other federal agencies to improve the availability of innovative technologies. It contains three sources of information on ground water characterization and cleanup technologies. Remediation Case Studies is a searchable collection of 140 case studies of sites using cleanup technologies, 53 of which relate to ground water remediation. Remediation Technologies Screening Matrix and Reference Guide, Third Edition, is a comprehensive guide to site cleanup technologies. Users can compare the applicability of multiple technologies for a specific contaminant and media, including ground water. Its reference list of technology information sources includes more than 1200 reports, many with links to electronic copies. Also on this website is the Field Sampling and Analysis Technologies Matrix and Reference Guide, which provides comparative screening information on analytical and sampling technologies.

GWRTAC: Ground Water Remediation Technology Center

GWRTAC is a private organization operated by the Concurrent Technologies Corporation in association with the University of Pittsburgh and funded by a Cooperative Agreement with EPA's Technology Innovation Office. The Center collects, analyzes, and prepares reports on in situ ground water remediation technologies. This web site contains definitions and dozens of reports on in-situ ground water cleanup technologies. Reports are available on the following technologies: in situ physical/chemical treatment (air sparging, horizontal wells, hydraulic and pneumatic fracturing, in-situ flushing, in-situ stabilization/solidification, in-well vapor stripping, surfactants/cosolvents, thermal enhancements, treatment walls); ex situ physical/chemical treatment (uv/oxidation); biological treatment (bioslurping, intrinsic bioremediation, phytoremediation); and electrokinetics.

SITE: EPA's Superfund Innovative Technology Evaluation Program

This web site contains the SITE Program Technology Profiles, 9th Edition (EPA-540-R-97-502), which describes each of the 190 cleanup and 28 measurement/monitoring technologies in the SITE program. The website also contains some of the reports documenting EPA's evaluations of innovative cleanup technologies. Under the SITE program, EPA enters into agreements with technology developers to further develop and/or demonstrate their technologies with support from EPA. EPA collects and disseminates engineering, performance, and cost data on the technologies.

SRIC: EPA's Subsurface Remediation Information Center.

This Information Center is a component of the Technology Support Center located at EPA's National Risk Management Research Laboratory in Ada, Oklahoma. The website contains numerous documents, including a comprehensive bibliography, related to ground water protection and cleanup.


"Supplemental Bulletin Multi-Phase Extraction(MPE) Technology for VOCs in Soil and Groundwater," April 1997.
OSWER Directive 9355.0-68FS, Publication EPA/540/F-97/004, NTIS Order Number PB97-963501, 15p.
Available on-line from OSWER (HTML)

This Quick Reference Fact Sheet is issued jointly by the U.S. EPA and Air Combat Command (ACC) of the United States Air Force (USAF) to provide information on the Multi-Phase Extraction (MPE) technology for extraction of volatile organic compounds (VOCs) present in soil and groundwater. This fact sheet recommends MPE as a potentially valuable enhancement for the SVE option under the presumptive remedy for sites with VOCs in soils.
