TEA has recently signed a licensing agreement with the U. S. National Aeronautics and Space Administration (NASA) to produce, distribute, and continue developmental work on the patented Activated Metal Treatment System (AMTS) technology. The technology has been demonstrated at multiple sites, including NASA’s Marshall Space Flight Center, Cape Canaveral Air Force Station, and Badger Army Ammunition Plant. The AMTS technology consists of an activated metal within a solvent system and a thickening agent to form a paste. The technology extracts PCB’s from materials such as paints and soils. The extracted PCB’s react with the activated metal and are degraded into benign by-products. TEA is scheduled to implement a pilot study on a site in the Northeastern United States in early 2010.

Toxicological & Environmental Associates, Inc. (TEA) is a leader in the design and implementation of engineered phytoremediation systems. TEA has enhanced and extended the effectiveness of standard phytoremediation by utilizing patented and proprietary technologies which direct root growth to achieve outstanding results. We’ve termed our unique approach EnPhySys.

EnPhySys¬† is an excellent “green” technology that can be successfully implemented almost anywhere. TEA currently has numerous projects underway in the United States and Canada, and current proposed work will significantly increase our number of engineered phytoremediation projects in 2010. Several of these projects combine other remediation technologies such as bioremediation and Emulsified Zero-Valent Iron (EZVI). The ability to combine these technologies is one of the most important benefits to using an engineered phytoremediation approach in solving your environmental cleanup issues.

For more information on this environmentally friendly technology, contact Dr. Brad Droy at 225-767-3880 or bdroy@teainconline.com

TEA has recently made significant updates and improvements to our EZVI manufacturing facility. Mr. Gary Booth has been hired as Manufacturing Supervisor, and he is responsible for daily operations and maintenance of the manufacturing equipment and facility, as well as raw material inventories and storage. TEA has completed equipment upgrades and manufacturing process refinements that currently enable us to produce over 1,000,000 gallons of EZVI annually.

Emergy Analysis is a formal methodology to equate economic worth of man-made structures, public services and assets to the services and assets provided by the environment. The economic value of natural resources is typically underestimated by classic economic analyses, which makes it difficult to justify the expenditures of large sums of monies for natural resource restoration projects for a perceived small return on investment. A full accounting of ecosystem services and the variable value of these services based on geographic position within the ecosystem construct must be identified if a true accounting of landscape value is to be determined. This accounting of economic values across a wide variety of resources, both man-made and natural, is achievable using the formal process of Emergy Analysis (Odum, 1996, 1998, 2000). Emergy accounting is particularly well suited for “public works” projects involving environmental restoration, and comparison of land use types.

Emergy (spelled with an “m”) is defined as a measure of the available energy required, directly and indirectly, to make a product or service. The quality of anything is measured by the emergy per unit and thus the real wealth of both man-made and environmental resources is measured directly. It is a way of calculating the value of both natural and man-made items on an equal basis and indicates their true contribution to the human economy. Emergy per unit of money measures real wealth buying power and is used to calculate emdollars, the economic equivalent used to compare ecosystem services.

TEA professionals have used Emergy Analysis in Florida and Alabama, and are well equipped to apply this technology to your particular situation. Please contact Dr. Don Blancher at 251-219-4161 or dblancher@teainconline.com for more information on the benefits of Emergy Analysis.

TEA can provide high quality subsurface groundwater and soil contaminant delineation services utilizing proprietary non-invasive techniques.  These remote sensing technologies have been utilized to delineate subsurface dissolved plumes, NAPLs, and pipeline leaks.  TEA works closely with their clients to understand the problems associated with each site and then designs the subsurface delineation using a layered technology approach.  Imagine having an image of the subsurface contaminant distribution at your site prior to remedial design!  These technologies can provide critical site information for designing in-situ remedial approaches. 

For further information on ways to implement these technologies within your given situation, please contact Dr. Greg Booth at 225-767-3880 or gbooth@teainconline.com.
