Guidance on Innovative Technology Risk Sharing (OSWER Directive #9010.02). This guidance was issued on March 24, 1998 jointly by the Office of Emergency and Remedial Response, the Office of Site Remediation Enforcement, and the Technology Innovation Office. It outlines EPA's program to share the risk of using selected innovative technologies. As a form of underwriting, this initiative is intended to remove a source of reluctance to try innovative approaches [March 1998, 7 pages including cover letter]. View or Print Directive .
Ground Water Issue Paper: Steam Injection for Soil and Aquifer Remediation (EPA 540-S-97-505). This issue paper was produced by the EPA Office of Research and Development. It contains detailed information on how steam injection can be used to recover organic contaminants from the subsurface, the contaminant and subsurface conditions for which the process may be appropriate, and general design and equipment considerations [January 1998, 16 pages].

Technology Evaluation Report: Phytoremediation (TE-98-01). This report, published by the Ground Water Remediation Technologies Analysis Center (GWRTAC) discusses five application types, including phytotransformation, rhizosphere bioremediation, phytostabilization, phytoextraction, and rhizofiltration. This detailed report discusses the current status of phytoremediation to treat soils and groundwater, including the science involved. Several field demonstration summaries are presented, with such information as: participants, compounds treated, site characteristics, results, and contacts. Also discussed are economics of the technology, regulatory requirements, and constraints and limitations of the technology. Download or view at http://www.gwrtac.org/html/tech_eval.html.
Innovative Site Remediation Technologies Design and Application: Liquid Extraction Technologies. This new edition, produced by the WASTECH Consortium, builds upon their earlier Phase I series and focuses on soil washing, soil flushing, and solvent/chemical extraction. This consensus-based engineering manual is written and reviewed by experts in the respective technology areas. It is available in hard copy only from the American Academy of Environmental Engineers (AAEE) at (410) 266-3390, fax (410) 266-7653 or email email@example.com.
A Dynamic Site Investigation: Adaptive Sampling and Analysis Program for Operable Unit 1 at Hanscom Air Force Base, Bedford, Massachusetts. This report was developed by the US EPA Region I - New England. It captures the results of the dynamic site investigation using field analytical instrumentation and methods to support a risk assessment study at Hanscom Air Force Base, Bedford, Massachusetts [January 1998, about 200 pages].

Ground Water Currents (EPA 542-R-98-004). Ground Water Currents is a newsletter that provides descriptions and performance data for developments in innovative ground water treatment. This issue highlights air sparging/high vacuum extraction to remove chlorinated solvents in ground water and soil and a 1,200-foot permeable reactive barrier in use at the Denver Federal Center [March 1998, 4 pages]. View or download from http://clu-in.org/techpubs.htm. Hard copy available in two weeks, contact (800) 490-9198 or (513) 489-8190 or fax your request to (513) 891-6685.
Exposure Factors Handbook, Volume I: General Factors (EPA-600-P-95/002Fa), Volume II: Food Ingestion Factors (EPA-600-P-95/002Fb), Volume III: Activity Factors (EPA-600-P-95/002Fc). These publications, produced by EPA's National Center for Environmental Assessment (NCEA), update the 1989 guidance that provided statistical data on the various factors used in assessing exposure. The revised Handbook provides up-to-date data on these exposure factors [August 1997]. View at http://www.epa.gov/cincl.
