Leon County Project [Back to Top]
The Center for Biomedical and Toxicological Research assisted in the development of Leon County's Hazardous Materials Emergency
Response Plan. The person responsible for this project was Heather Ritchie. She began with reviewing the 1998-1999 Leon County
Extremely Hazardous Substances (EHS) Inventory Book. Mrs. Ritchie visited each site containing EHS to collect data from each
facility contact regarding types and quantities of regulated materials, which are managed at the facility. She then input each
facility into CAMEO (Computer Aided Management of Emergency Operations) for future evaluations. The final product was submitted
to the Director of the Leon County Office of Emergency Management to produce Hazards Evaluation summary maps for each facility.
CBTR has conducted this study for Leon County since 1991. We hope to continue cooperation with the Leon County in the future.
DNAPL Project at Cape Canaveral [Back to Top]
Historical uses of Chlorinated solvents as well as other widely used dense non-aqueous phase liquids (DNAPLs) pose serious
long-term groundwater contamination problems in the United States and in other industrialized countries.
The U.S. Department of Energy (DOE), the National Aeronautics and Space Administration (NASA), the U.S. Environmental Protection
Agency (EPA), the U.S. Department of Defense (DOD), U.S. Navy (NAVFAC) and the U.S. Air Force have formed the Interagency DNAPL
Consortium (IDC) in order to conduct comparative demonstrations of DNAPL remediation technologies Since its inception, CBTR
has served to provide technical support to the IDC and field engineering management to the technology demonstrations conducted at
Launch Complex 34.
The IDC has selected three promising DNAPL remediation technologies for a comprehensive evaluation at Launch Complex 34 (LC34)
at Cape Canaveral, Florida. LC34 is the site of the tragic Apollo 1 fire which occurred in 1967. Its use as a launch facility
and rocket motor cleaning site resulted in subsurface DNAPL contamination involving chlorinated cleaning agents. Col. John
Koutsandreas of the CBTR, Mr. Skip Chamberlain of the DOE and Dr. Tom Early of Oak Ridge National Laboratory provide technical
support and supervision, and assist in the management of this technology demonstration project.
The three technologies selected for evaluation are chemical oxidation with potassium permanganate, Six Phase HeatingTM and Steam
with Co-Air injection. To date, the oxidation and Six Phase Heating technologies have been deployed and cost and performance
reporting are being prepared. The third technology is currently in operation with an expected completion later this year.
It is anticipated that all reporting will be completed by March of 2002.
Deployment of Chlorophyll Fluorometer in Phytoremediation Experiments [Back to Top]
The chlorophyll fluorometer (CFM-636973) is a portable instrument produced and tested by Technical University of Budapest
(Hungary) in the framework of an ongoing U.S. DOE-funded cooperative research initiative between FSU and universities and
institutions from Central and Eastern Europe. The chlorophyll fluorometer uses changes in chlorophyll fluorescence to determine
the general health status of a plant. This equipment can be used in the lab as well as in the field to measure chlorophyll
fluorescence kinetics. Chlorophyll fluorescence is a part of the light energy absorbed by plants which is not used for
photosynthesis, being re-emitted through a radiant de-excitation process. At lower photosynthetic activities, the re-emitted
portion of energy, including fluorescence, increases. Consequently, measuring chlorophyll fluorescence is a widely accepted
in vivo method for investigations of plant health.
DOE-IETU Joint Coordinating Committee for Environmental Science (JCCES) [Back to Top]
The U.S. Department of Energy/Office of Environmental Management/Office of Science and Technology (DOE), the Institute for
Ecology of Industrial Areas (IETU) in Katowice, Poland and Center for Biomedical and Toxicological Research have been
cooperating on the development and implementation of innovative environmental remediation technologies since 1995.
The project is conducted under the DOE's Joint Coordinating committee for Environmental Systems. The objective of this
cooperative activity is to use expertise and technologies developed in Central and Eastern Europe to address environmental
problems within the DOE complex. The following areas of cooperation currently are under development:
1. Biologically-based technologies to remove toxic heavy metals (e.g., lead, mercury) from soil,
2. Biologically-based and chemically based methods to stabilize contaminants in soil,
3. Implementation of bioremediation for the cleanup of petroleum contaminated soil, and
4. Modification of the petroleum contaminated soil bioreactor to treat chlorinated solvent contaminated soil.
