Throughout his career, Jim's projects have involved diverse environmental media and concurrent interactions with multiple regulatory agencies. A particular focus of his is the long-term management of hazardous and non-hazardous solid waste facilities. He has led hundreds of programs that resulted in the successful remediation, closure, post-closure, and reuse or redevelopment of waste disposal facilities, primarily in the United States. Jim also has designed and managed a sizable portfolio of landfill gas collection and control systems throughout the United States and leachate management initiatives along the Texas Gulf Coast.
Jim's experience with poly- and perfluoroalkyl substances (PFAS) centers on landfill-related litigation cases. He has evaluated the occurrence of PFAS compounds in landfill leachate, groundwater, and biosolids and evaluated potential PFAS impacts related to a local publicly-operated treatment works. He has also provided senior-level support to respond to new state requirements to sample and report on groundwater and leachate results for PFAS compounds.
Jim's expertise also extends to in situ treatment of contaminated soil and sediment; contaminated soil excavation and disposal; contaminated sediment dredging and treatment; transportation of hazardous and industrial waste; contaminant investigation and delineation; groundwater containment, recovery and treatment; stream restoration; and Brownfields redevelopment. He has extensive experience managing and providing support for environmental legal proceedings, litigation, and environmental insurance recovery. He frequently develops estimates of fair value of environmental remediation liabilities for corporate entities.
To advance the state of the practice, Jim is working with university researchers to evaluate potential PFAS destruction technologies such as sodium catalyst reduction and mineralization and using specialty anodes for application in industrial wastewaters.
