For Immediate Release

Press Release

HANOI, July 27, 2023 – Today, the U.S. Agency for International Development (USAID) announced a $32 million contract to the U.S. firm Tetra Tech to continue the cleanup of dioxin-contaminated soil in and around the Bien Hoa Air Base. Under the contract, Tetra Tech will provide engineering design, construction management, and environmental monitoring of civil works and treatment activities for dioxin-contaminated soil and sediment to reduce the risk of exposure to people on the air base as well as in the bordering communities to restore the land for full use. 

In March, during her visit to Vietnam, USAID Administrator Samantha Power joined other U.S. and Vietnamese government officials to announce another contract of up to $73 million awarded to Nelson Environmental Remediation USA, an American small business, to design and build a treatment facility to decontaminate soil and sediment on and around the Bien Hoa Air Base.

Since April 2019, USAID has worked with the Ministry of National Defense (MND) to remediate approximately 500,000 cubic meters of dioxin-contaminated soil and sediment on and around the Bien Hoa Air Base. In 2022, USAID completed remediation of an off-base lake (Gate 2 Lake) and returned it to the community for use as a recreational area, completed remediation of the first on-base area (Southwest area), commemorating this milestone with a U.S. government-funded park on the site, and completed the construction of the long-term storage facility for soil with low levels of contamination. 

Dioxin remediation at Bien Hoa Air Base Area project is expected to take 10 years to complete and cost an estimated $450 million. The U.S. government’s contribution to-date is $218.255 million out of a total expected commitment of $300 million. 

This year, the United States and Vietnam are celebrating the 10-year anniversary of their Comprehensive Partnership. Our close cooperation over the past decades to overcome legacies of war is yet another example of how the United States and Vietnam work strategically together to create a better future for our two peoples.
