# GAO Upholds EPA's $67 Million Superfund Award

The Government Accountability Office denied Tetra Tech Inc.’s protest of the U.S. Environmental Protection Agency’s $67 million Superfund technical assessment and response advisory and assistance services contract, allowing awardee Weston Solutions Inc. to proceed with work in several Mid-Atlantic states. GAO found EPA reasonably determined that Tetra Tech’s proposed environmental technician did not meet the solicitation’s requirements. For procurement teams and bidders, the decision underscores that proposed personnel qualifications are evaluated against stated solicitation criteria and that a protest must substantiate claims of evaluation error.

- Weston Solutions remains positioned to perform the **$67 million** contract; the work supports EPA’s Superfund-related activities across several Mid-Atlantic states.
- Offerors should verify that proposed personnel meet each stated qualification and provide clear supporting evidence in their submissions.
- Agencies can use the decision as a reminder to document how proposal evaluations apply solicitation requirements, particularly when assessing key staff.
