Tetra Tech, Inc.'s Environmental and Infrastructure Division (operating as Tetra Tech Em Inc.) was awarded a $173,942.40 delivery order under the EPA Region 7 Superfund Technical Assessment & Response Team VI (START VI) contract for remedial action support at the Cherokee Zinc-Weir Smelter site in Shawnee, Kansas. This delivery order, issued on August 18, 2025, with an ultimate completion date of March 5, 2027, represents Modification P00001 to the parent task order and provides a revised statement of work and price schedule for additional sampling activities at this contaminated site. The work is funded by the Environmental Protection Agency through its Region 7 office and structured as a time-and-materials contract with no small business set-aside designation, reflecting Tetra Tech's established status as a large federal contractor.
The award supports EPA's Superfund program, which addresses the remediation of hazardous waste sites across the United States. Tetra Tech's parent START VI contract, valued at $94.4 million through June 30, 2028, provides comprehensive environmental assessment, emergency response, and technical support services for contaminated properties throughout the Midwest. The Cherokee Zinc-Weir Smelter site represents one of several mining-related and industrial remediation projects in Tetra Tech's portfolio across EPA Regions 2 and 7, where the company provides specialized expertise in site investigations, hazardous waste management, sampling and analysis support, and remedial action planning. Tetra Tech typically engages qualified subcontractors for drilling, soil sampling, and laboratory analysis services on such environmental remediation projects.
