Editorial Note. Periodically we get feedback from subscribers that one or two of the links we provide will not work. Typically, we get this feedback from subscribers whose E-mail system does not allow the listed URL addresses to be hotlinked. In those instances, subscribers often block and copy an address from the text of the message into their browser. Because most of the URLs listed in TechDirect’s entries are located at the end of sentences, they are followed by a period (.). The period has been the cause of the problem. Please, if you run into a problem with a URL that does not work, try it again making sure to eliminate the period.

EPA Guidance

Use of Monitored Natural Attenuation at Superfund, RCRA Corrective Action, and Underground Storage Tank Sites, OSWER's Policy Directive (No. 9200.4-17P). Now available as a Final Directive! This Directive provides guidance to EPA staff, to the public, and to the regulated community on how EPA intends to exercise its discretion in implementing national policy on the use of Monitored Natural Attenuation for the remediation of contaminated soil and groundwater at sites regulated under Office of Solid Waste and Emergency Response (OSWER) programs.

Databases and Documents

EPA REACHIT. If you are familiar with EPA’s downloadable remediation and characterization vendor databases (VISITT and Vendor FACTS) and our technology applications database (Innovative Treatment Technologies), they are now combined in a searchable Internet-based (i.e., no downloading) system called REACH IT. The REmediation And CHaracterization Innovative Technologies system is a source of information on the availability, performance, and applications of remediation and characterization technologies. EPA REACH IT is intended to assist remediation professionals in their treatment, characterization, and monitoring decision-making process by tracking the deployment of technologies and identifying firms that provide assessment and remediation services. EPA REACHIT is located at http://www.epareachit.org.

Ground Water Currents (EPA 542-N-99-002). This EPA quarterly newsletter provides descriptions and performance data for developments in innovative ground water treatment. This issue features innovative permeable reactive barriers used to remediate contaminated ground water [March 1999, 4 pages]. View or download at http://clu-in.org/techdrct/techpubs.htm. Hard copies available from (800) 490-9198 or (513) 489-8190 or fax your request to (513) 891-6685.

Subsurface Containment and Monitoring Systems: Barriers and Beyond. This report was prepared under grant for EPA’s Technology Innovation Office by Leslie Pearlman, a National Network of Environmental Management Studies fellow. The publication provides an overview of subsurface barriers - vertical and horizontal - with an emphasis on the emerging and innovative vertical barrier technologies. It is not intended to be an inclusive report; it merely provides an overview of the existing work in the field on subsurface barrier technologies. The information was gathered from a range of available sources, including project documents, reports, periodicals, Internet searches, and personal communication with involved parties [March 1999, 68 pages]. View or download at http://clu-in.org/techdrct/techpubs.htm.

Bibliography of Field Applications of Permeable Reactive Barrier Technology. This bibliography was produced by the Remediation Technologies Development Forum (RTDF). It lists approximately 200 citations related to field applications of barrier walls. The bibliography is searchable by author, title, abstract, and the site to which the citation applies. To access the bibliography, see http://www.rtdf.org/public/permbarr/barrdocs.htm. Note that this site also contains 1-2 page profiles of selected pilot and full scale permeable reactive barrier applications.

Emerging Technology Summary Report: Simultaneous Destruction of Organics and Stabilization of Metals in Soils (EPA/540/SR-98/500). This document was published by EPA Superfund Innovative Technology Evaluation (SITE) Program. The EPA National Risk Management Research laboratory conducted a laboratory evaluation of the Sulchem process to treat soils contaminated with organic hydrocarbons and heavy metals. The Sulchem process mixes the contaminated media with elemental sulfur at elevated temperatures in an inert reactor system [July 1998, 10 pages].

Conferences and Symposia

1999 Conference on Hazardous Waste Research, St. Louis, Missouri, May 25-27, 1999. This conference is sponsored by the Great Plains/Rocky Mountain Hazardous Substance Research Center. It will highlight several broad areas of hazardous waste research including brownfields redevelopment and contaminated sediments as well as industrial and mine- contaminated soils and groundwater. Case studies, demonstration projects, and research findings surrounding technical and institutional issues will also be included. Oral and poster presentations, panel discussions, and training workshops on these topics will be presented with an eye toward strengthening existing partnerships and developing new alliances to promote simple, cost-effective compliance, cleanup, and integration of hazardous sites. Additional information about the conference is available on the Great Plains/Rocky Mountain HSRC web site at http://www.engg.ksu.edu/HSRC.
