Tetra Tech’s scientists and engineers have performed thousands of assessments and scoping studies at the outset of a project to optimize solutions based on factors such as cost, schedule, and human health and environmental benefit.

Tetra Tech conducts assessments and scoping studies for all media, including air, water, infrastructure, and soils.
