Road Map to Understanding Innovative Technology Options for Brownfields Investigation and Cleanup (EPA 542-B-97-002). This document focuses on the site characterization and cleanup phase of Brownfields redevelopment. It provides a framework of logical steps involved in the characterization and cleanup of a Brownfields site in order to link technology options and resources to each of these steps [June 1997, 64 pages]. Download or view from http://clu-in.org/techpubs.htm#July. Hard copies should be available in two weeks. Contact NTIS at (703) 487-4650.

AATDF Technology Practices Manual for Surfactants and Cosolvents (TR-97-2). This manual, produced by the DOD Advanced Applied Technology Demonstration Facility Program at Rice University, is intended to assist decision makers with the evaluation and potential application of surfactant/cosolvent flushing for the remediation of subsurface contamination. The report provides a basic understanding of the technologies, their applicability and limitations, and an understanding of the factors to be considered when implementing projects. A limited number of hard copies are available. Fax your request to Dr. Don Lowe at (713) 285-5948. Please include your full name and title, affiliation, mailing address, phone number, fax number, and email address. A draft html version of the report may be downloaded at http://clu-in.org/techpubs.htm#July. The internet version will be improved. DOD/AATDF will prepare a CD ROM version of the Technology Practices Manual before August 31.

Innovations in Ground Water and Soil Cleanup: From Concept to Commercialization This report published by the National Research Council provides an up to date review of the capabilities and limitations of existing ground water and soil cleanup technologies. The report also recommends solutions to institutional problems and other factors that have stifled innovation in the ground water and soil cleanup industry [June 1997, 265 pages]. Prepublication hard copies are available from National Academy Press for $45 plus $4 shipping/handling. Contact (800) 624-6242 or (202) 334-3313. When the report is published in October, it will be downloadable from http://www.nap.edu.

Issue Paper: How Heat Can Enhance In situ Soil and Aquifer Remediation (EPA 540-S-97-502) This issue paper developed by the Office of Research and Development, contains in-depth information on the properties of some common organic contaminants that affect their movement in and recovery from the subsurface as well as information on how these properties are affected by temperature [April 1997, 18 pages].

Field Portable Characterization and Monitoring Technologies. The EPA Technology Innovation Office is studying the use of field portable technologies for site characterization. This is part of a broad TIO effort to increase the acceptance of these technologies. Documenting the deployment of field portable technologies for site assessment will help other potential users understand that the technologies have a track record. If you know of actual sites where field portable technologies have been used in lieu of traditional laboratory sampling methods (and the information can be made publicly available), we are interested in hearing from you.
