TerraTherm and e2M Use ISTD for Pollution Cleanup at Former U.S. Army Memphis Depot, Part of DLA Project That Wins 2009

FITCHBURG, MA, May 19 (MARKET WIRE) --
TerraTherm, Inc. has announced the successful completion of a pollution
cleanup project at the U.S. Defense Logistics Agency's former Memphis
Depot, an important step in the overall environmental remediation of that
Base Realignment and Closure (BRAC) site, which has become an engine for
economic development in the area. Working with engineering-environmental
Management, Inc. (e2M) of Denver, Colorado, TerraTherm applied In Situ
Thermal Desorption (ISTD) to remove a total of approximately 5,675 kg
(12,500 lbs) of contaminants, representing 99.99% of chlorinated volatile
organic compounds (CVOCs) that were present in high concentrations in the
loess treatment area, extending from the ground surface to approximately
30 feet below ground surface (bgs). The Defense Logistics Agency has been
awarded the 2009 Secretary of Defense Environmental Award for
Environmental Restoration for overall project performance.

"This site was very well suited to ISTD, which employs thermal conduction
heating and vacuum extraction simultaneously, because of its large target
volume of 38,200 cubic meters (49,950 cubic yards), subsurface CVOC DNAPL
material at depths of up to 9 meters (30 feet), and very stringent cleanup
goals. That excellent fit enabled us to design an ISTD process that fully
treated the site in a cost-effective manner," said Ralph Baker, CEO of
TerraTherm, Inc.

Memphis Depot was activated as a storage and logistics site by the U.S.
Army in January 1942 and closed in 1997 as part of the BRAC process. The
project design confronted a number of complexities and required an
innovative approach involving a combination of technologies, according to
Tom Holmes, Project Manager of e2M, the overall remediation contractor at
the former Memphis Depot. "The site was challenging in many respects, and
TerraTherm's ISTD was an excellent partner to e2M in addressing soil
contaminations in the loess treatment areas. Their design and execution of
the thermal treatment and the amount of mass removed were significant
contributors to the achievement of this prestigious award from the
Secretary of Defense."

These dramatic reductions in contaminant mass and soil concentrations at
the site have resulted in successful closure of all eight targeted source
areas in the loess treatment area and in improved long-term protection of
the water supply both at Memphis Depot and in the broader community.
