USAID Awards Thermal Remediation Design Contract to TerraTherm for Dioxin Cleanup at Danang Airport, Vietnam

FITCHBURG, MA--March 20, 2012 – The U.S. Agency for International Development (USAID) has
awarded TerraTherm, Inc. a thermal remediation design contract for cleanup of dioxin-contaminated
soil and sediment at the Danang Airport in Vietnam. The design is expected to be completed in
August 2012. Working in close coordination with the Government of Vietnam (GVN), USAID will
present the preliminary designs to the GVN in May and July, so that the GVN can consider the
technology as part of final project approvals.

The Danang Airport is one of the major dioxin hotspots remaining from the storage and handling of
Agent Orange during the Vietnam War. Ultimately, the clean-up at Danang will better protect the
health of the nearly 800,000 nearby residents and facilitate the implementation of airport expansion

USAID has proposed the use of the In-Pile Thermal Desorption® (IPTD®) technology for treatment of
approximately 95,000 cubic yards of soil and sediment at the Danang Airport. The IPTD approach
would incorporate an above-ground, covered and fully insulated treatment pile structure to be filled
with soil and then heated to destroy the dioxin. Once approved and implemented, the technology can
safely and effectively treat the soil to the required Vietnamese clean-up levels, as has been
demonstrated at similarly-sized projects in the United States.
