Delivery Order 68HE0725D0006-68HE0726F0073

Tetra Tech, Inc.'s Environmental and Infrastructure Division (operating as Tetra Tech Em Inc.) was awarded a $38,710.73 delivery order on April 13, 2026, for removal site evaluation services at the 10th Street Site in Columbus, Nebraska, under the EPA Region 7 Superfund Technical Assessment & Response Team VI (START VI) contract. This delivery order, which will be completed by September 30, 2026, is structured as a time-and-materials contract with no small business set-aside designation. The work supports the U.S. Environmental Protection Agency's Superfund program, which addresses environmental remediation and cleanup of contaminated properties across the Midwest region. Tetra Tech will conduct site evaluation activities necessary to assess contamination conditions and support removal action planning at this Columbus location.

This delivery order falls under Tetra Tech's larger $94.4 million single-award EPA Region 7 START VI indefinite delivery vehicle, which extends through June 30, 2028, and provides comprehensive environmental assessment, emergency response, site investigation, groundwater treatment, risk assessment, and hazardous waste cleanup services across the Midwest. Tetra Tech's extensive experience delivering hundreds of similar task orders—valued between $4,000 and $2.7 million—at contaminated Superfund sites including the Newton County Mine Tailings, Cherokee Zinc-Weir Smelter, and Big River Mine Tailings demonstrates the company's established capability as a primary environmental services contractor for the EPA.
