Brian Hitchens is a Senior Principal Hydrogeologist with more than 20 years of experience focused on site assessment and remediation, contaminated sediment management, and litigation support.
Brian routinely works with clients and regulators to identify clear pathways to site closure, with innovative and cost-effective remediation strategies. He has achieved site closure and no-further action determinations on behalf of Geosyntec’s clients at a wide range of project sites, including large manufacturing facilities, former chrome plating shops, and contaminated sediment sites. These projects have involved the assessment and remediation of chlorinated solvents, petroleum hydrocarbons, hexavalent chromium, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and pesticides.
Specializing in the application of environmental forensics, Brian can help identify and differentiate sources of contaminants in complex environments involving multiple potential dischargers. He has extensive experience with source assessment for PCBs in building materials, soils, sediments, storm drains, and sanitary sewer systems. Brian has also designed and managed the implementation of many large scale in-situ remediation programs through a wide range of remedial approaches, including enhanced bioremediation, in-situ chemical reduction, zero-valent iron, zero-valent zinc, electrical resistive heating, and hydrogen sulfide injection.
Brian assists clients with the design and implementation of enhanced natural recovery (ENR) remedies at many sites along the west coast of the United States. He directed the design and implementation of the first thin-layer carbon enhanced cover to mitigate PCB impacted sediments in San Diego Bay. This cost-effective solution was designed to achieve very low regulatory thresholds for PCBs, while minimizing the need for large-scale dredging. Following implementation, the carbon enhanced sand cover met all project design objectives, resulting in a no-further action determination for the site.
In his role as a litigation consultant, Brian has supported attorneys at national law firms and in-house corporate counsel, providing technical review, forensic assessment, data analysis, and assessment of opposing expert positions. Brian has coordinated large litigation support teams providing overall case strategy support and focused on finding the key documents and data that can fundamentally change the outcome of a case in the of tens of millions of documents commonly obtained in the discovery process.
