Among Jeff's key strengths is his broad experience helping clients manage investigations and corrective actions at complex sites contaminated by chlorinated solvents, petroleum hydrocarbons, and inorganic compounds. He has notable experience assisting clients with challenging contaminants such as 1,4-dioxane, and has addressed these at sites regulated under various RCRA, CERCLA, state-led, and voluntary cleanup programs. His practice also includes developing multi-party solutions with stakeholders in the private sector, legal, governmental, and regulatory arenas.
Jeff advances the state of the practice with the development, feasibility evaluation, and application of innovative remedial technologies. Remedial systems designed or implemented under his direction include soil mixing with steam and zero-valent iron amendments, excavation, bioaugmentation, in situ chemical oxidation, in situ stabilization/solidification, phytoremediation, pump and treat with advanced oxidation reactor systems, multiphase extraction, air sparging, soil vapor extraction, and monitored natural attenuation.
Complementary to his experience with environmental assessment and remedial activities, Jeff performs environmental due diligence and environmental liability valuations for multi-national industrial clients in support of commercial property transactions, brownfields redevelopment and global liability portfolio management. He also has significant experience evaluating the vapor intrusion pathway of methane and organic vapors in the subsurface, and the design of both passive and active vapor intrusion mitigation systems (pre-construction and retrofitting) to protect human health within buildings and structures.
