Tetra Tech, Inc. (NASDAQ: TTEK), a leading provider of high-end consulting and engineering services in water, environment, and sustainable infrastructure, announced today that the City of Dayton, Ohio Department of Water, selected Tetra Tech for a single-award contract to design advanced treatment solutions for what will be the largest dedicated per- and polyfluoroalkyl substances (PFAS) treatment facility in the United States, with a projected construction cost of $350 million.

Under this eight year contract, Tetra Tech engineers, scientists, and technical specialists along with staff will build on our prior planning work to implement innovative solutions to address legacy regional PFAS contamination in the Mad River Well Field, which serves the City’s 70-year old Ottawa Water Treatment Plant, generating 96 million gallons per day of drinking water. In collaboration with the City’s Department of Water engineers, operators, technical staff and key stakeholders, our water treatment experts are developing high-efficiency designs that will address PFAS regulations and aging infrastructure, while minimizing long-term operating costs. By protecting Dayton's water source, this project ensures a safe, regional, reliable, and renewable water supply for their community for generations.
