Tetra Tech GEO

Tetra Tech GEO distinguishes itself from the competition by its continued invitation by the USEPA to write state-of-the-practice guidance manuals on site characterization and remedial design. Since 1990 we have co-authored over a dozen technical publications for various EPA offices, including the Office of Research and Development, the Technology Innovation Office, and the Office of Underground Storage Tanks. Below we have listed the publications that Tetra Tech GEO personnel have authored and/or co-authored for EPA. These publications exemplify the high-quality work that we have provided for EPA and numerous other clients. In addition, many of these publications continue to serve as the industry standard for site characterization and remedial design.
