Biography

Dan Griffiths, VP, CPG, PG, brings both a strong classical geological science education and extensive experience to a wide variety of projects, focusing on streamlined site delineation and innovative remedial design and implementation. He has been designing and implementing investigation plans at industrial and Department of Defense (DoD) sites for more than 27 years, specializing in complex high priority sites impacted with chlorinated solvents, metals, explosive constituents, and emerging contaminants including per and polyfluoroalkyl substances (PFAS) and 1,4-dioxane. He is a contributing author on guidance documents for in-situ remediation prepared by Parsons for the Air Force and Environmental Security Technology Certification Program (ESTCP) and he is a contributing author on the Interstate Technology and Regulatory Council (ITRC) PFAS and emerging contaminants teams. Dan is also a Parsons Fellow, the Innovation and Technology Director, and Senior Science Advisor for emerging contaminants like PFAS.
