Tetra Tech, the Pasadena engineering and consulting firm, has won a $16.8 million federal contract to help the U.S. Environmental Protection Agency return contaminated properties to productive use.
The four-year award, which the company announced Aug. 24, places the publicly traded Pasadena firm at the center of the EPA’s national Land Revitalization Program — the agency’s work to assess, clean up and redevelop brownfields and other contaminated sites across the country. Federal contracting records list the award at $16,815,495.46 and show Tetra Tech was selected over three other bidders.
Under the contract, Tetra Tech staff will provide land-use planning, engineering design and technical support to EPA regional staff and communities working to reuse contaminated land, the company said in its announcement. The described scope includes site assessments, guidance on sustainable redevelopment and economic analysis of potential reuse.
The company attributed the award to the EPA’s Office of Brownfields and Land Revitalization. Federal contract records file it under the agency’s broader Office of Land and Emergency Management, which houses that office.
Tetra Tech (NASDAQ: TTEK) is headquartered at 3475 East Foothill Boulevard in Pasadena. Founded in 1966, the firm provides consulting and engineering services in water, environment and infrastructure and employs more than 25,000 people worldwide, according to the company.
In the announcement, Chief Executive Roger Argus said Tetra Tech has supported the EPA’s redevelopment of brownfields and contaminated properties for more than 30 years and would continue that work, which he said aims “to return land to productive use while protecting human health and the environment.” Argus became chief executive in February 2026, succeeding Dan Batrack, who moved to the role of executive chairman.
The contract is the latest in a series of federal environmental awards for the firm. In 2023, Tetra Tech was named to a $450 million multiple-award EPA contract for sediment cleanup in the Great Lakes and received a $65 million EPA contract to support cleanup of abandoned uranium mines on Navajo land.
For a company that began in 1966 as a water-engineering group, the new award adds to a federal environmental portfolio that reaches from the Great Lakes to the Southwest — directed, as it has been for years, from an office on East Foothill Boulevard.
