The contract has a ceiling value of $79,976.00 and was awarded on August 11, 2015, with an ultimate completion date of April 28, 2017. Tetra Tech has a long history of supporting the EPA across various environmental programs, including water quality monitoring, data analysis, environmental modeling, and technical assistance. This specific contract does not have a set-aside designation, reflecting Tetra Tech's status as a large business. The award is not associated with a larger contract vehicle, but Tetra Tech does hold two significant indefinite delivery/indefinite quantity (IDIQ) contracts with the EPA for ecological assessment, global climate change research, and water quality standards support services.
