Technology Evaluation Verification of Decision Support Software for Site Characterization. The EPA Environmental Technology Verification (ETV) program pilot for site characterization and monitoring technologies will be verifying environmental decision support software packages that focus on site characterization, plume characterization, and/or data worth. Jointly sponsored by the U.S. DOE Environmental Management Program, the verification testing will be coordinated by Oak Ridge National Laboratory's (ORNL) Chemical and Analytical Sciences Division. ORNL is serving as the verification organization on a number of ETV verification projects. A developers kick-off meeting will be held February 18 in San Francisco.

Symposium Biological and Chemical Reduction of Perchlorate and Chlorate. The US EPA National Risk Management Research Laboratory will host a one-day symposium held in Cincinnati on Friday, December 5, 1997, from 8:30 am to 6:00 pm on the biological and chemical reduction of perchlorate and chlorate. This topic has gained notoriety since high levels of perchlorate were TechDirect: December 1, 1997 2 of 3 clu-in.ora/newsletters ------- discovered in ground and surface waters in regions of California, Nevada, and Utah. The symposium will feature : Professor James Espenson (Iowa State Chem Dept) will discuss the kinetic barriers to perchlorate reduction and some of his recent work with metal cations that can abstract oxygen atoms from perchlorate, eventually reducing it to chloride; Professor Bruce Logan (Penn State Env Engr Dept) will discuss bacterial reductases and his research on microbes that will consume chlorate and perchlorate; Jim Hurley (USAF, Tyndall AFB) will discuss the use of Wolinella succinogenes to reduce perchlorate in bulk reactors for the treatment of waste effluents that contain perchlorate; Joel Tenney (Eka Chemical, Georgia, American division of Akzo Nobel) will discuss the formation of chlorate and chlorite in treatment plants that use chlorine dioxide and how they may be removed; C.G. van Ginkel (Akzo Nobel, Netherlands) will discuss how Proteobacteria can reduce perchlorate and recent research there on isolating the reductase responsible for this behavior. Admission is free, but all attendees must have pre-registered to be admitted. Contact Edward Urbansky by email at urbanskv.edward@epamail.epa.aov. Field Portable Site Assessment Technology The Technology Innovation Office is interested in identifying and documenting commercial use of field portable site assessment technologies by hazardous waste professionals. In particular, we are interested in identifying innovative analytical or geophysical approaches for detection and delineation of Dense Non-Aqeous Phase Liquids (DNAPLS) in soil and groundwater. If anyone has any leads or general knowledge of sites where DNAPLs have been detected and mapped using field portable technologies, please contact Carl Ma of TIO at (703) 603-9903 or ma.carl@epamail.epa.aov. *to subscribe* send an email to lyris@lists.epa.gov and in the body of the message type: subscribe TechDirect [your first and last name] *to unsubscribe* send an email to ivriS@iiSts.em.aov and in the body of the message type: unsubscribe TechDirect If you have any questions or suggestions, contact Jeff Heimerman at, heimerman.ieff@epamail.epa.gov. http://clu-in.org/techdrct/td1297.htm Page last modified: October 12, 1998 TechDirect: December 1, 1997 3 of 3 clu-in.ora/newsletters ------- |
