Principal - Contaminated Sites Assessment & Remediation
Cardno GS

Mr. Tyler has served as a remediation engineer and project manager for the past 28 years. His focus has been assisting clients faced with challenging contaminated sites to find effective and sustainable solutions. He has worked with a diverse range of clients inclusive of the Department of Defense, industrial, and commercial sectors and on sites ranging from current/former military bases, landfills, dry cleaning facilities, manufacturing facilities, fueling stations, airports, and more. Mr. Tyler has a depth and breadth of expertise in characterizing and remediating contaminants such as but not limited to, emerging contaminants (PFAS; 1,4-dioxane; perchlorate), chlorinated solvents, hexavalent chromium/metals; fuel/jet fuel, munitions and explosives of concern (MEC), and sites with radiological concerns. He specializes in the in situ remediation of contaminants with expertise with high-resolution site characterization, bench/pilot testing, and treatment using chemical oxidation, bioaugmentation/enhanced bioremediation, physical approaches to remediation (e.g., thermal), and more. Mr. Tyler received a patent for an in situ bioremediation process to address large dilute contaminated plumes (U.S. Patent No. 8,580,114). He has also been providing leadership within the ITRC for more than a decade serving on teams such as PFAS; Perchlorate Remediation; Integrated DNAPL Site Strategy; DNAPL Characterization; Characterization and Remediation of Fractured Rock (current ITRC trainer); and 1,4-Dioxane (current ITRC trainer). In addition, he has received awards as related to multidisciplinary applications for remediation and innovative remediation from such institutions as the American Council of Engineering Companies (ACEC).


Management and Remediation of PFAS

Federal PFAS sites are being managed through the CERCLA process. However, there exists what has been described as a “remedial investigation roadblock” – the challenge of completing a human health/ecological risk assessment, and the subsequent challenge of identifying feasible technologies for addressing PFAS in a feasibility study. This presentation will present an overview of PFAS chemistry, analysis, toxicology, federal screening/advisory levels, and management/remediation technologies. The discussion will focus on releases of AFFF and will be framed to support the completion of a PFAS risk assessment as part of the remedial investigation and to support subsequent remedial alternative development. In addition, a PFAS management tool will be introduced that can be utilized to support setting remedial investigation objectives and for screening remedial technologies.
