James (Yu-Sheng) Wang is a Principal Environmental Engineer based in Maryland with more than 25 years of experience focused on developing and applying innovative assessment and remediation technologies. James has built his practice by providing clients with cost-effective solutions specifically tailored to solving their most challenging problems.
James has extensive research and consulting experience in developing and engineering chemical and biological treatment technologies to address chemical contaminants under complex environmental conditions. He has directed and led research projects funded by government agencies and industrial clients to advance and demonstrate innovative technologies for waste treatment and management, bioreactor landfill, electrokinetically (EK) enhanced in situ groundwater remediation, and submerged attached-growth bioreactor for advanced wastewater treatment. James has led and managed investigations and corrective action projects at sites regulated under RCRA, CERCLA, state-led, and voluntary cleanup programs. For these projects, he developed and implemented engineering solutions targeting soil and groundwater impacted with petroleum hydrocarbons, chlorinated solvents, and metals.
Applying his in-depth understanding of physicochemical and microbiological processes governing the behavior and affecting the fate of chemical compounds in the environment, James has been able to develop, design, and implement site-specific remedial approaches that often combine multiple unit operations to achieve ultimate site remediation goals.
Among his novel remediation projects is the full-scale implementation of electrokinetically enhanced bioremediation (EK-BIO) for DNAPL source remediation, which is the first rigorous field demonstration of this technology in the world. The project's success advocates EK technology as a cost-effective solution for the fundamental challenge of remediating low-permeability materials and sites with high degrees of geologic heterogeneity.
James continues to advance the state of the practice through publications of peer-reviewed journal articles and conference presentations and proceedings. He has provided short courses and workshops as well as published extensively on the results of his research projects, technology evaluations, and field demonstrations in the practice areas of waste treatment and environmental remediation.
