Publications & Presentations

Working with our clients, Geosyntec professionals prepare technical papers and presentations that document the significant findings of our project work. Working with academic colleagues and government researchers, we publish and present the findings of our research at forums with an international reach.

Today, nearly 10 percent of our annual revenue is associated with applied research and development on a variety of topics including soil and groundwater remediation, geotechnical engineering for highways, landfill gas management systems, and urban stormwater best management practices.
