James Langenbach, P.E.

James Langenbach is a Senior Principal Environmental Engineer for Geosyntec Consultants based in Florida with more than 20 years of experience focused on assisting clients with environmental assessments; remediation design and treatment system optimization; environmental management systems; sustainable remediation designs; and regulatory compliance.

For decades, a wide range of industries have used chlorinated solvents as degreasing agents and similar commercial applications. In many places throughout the world, these solvents have seeped into the ground near work sites, either through spills or as runoff, creating dense plumes of contaminants that can threaten aquifers and ecosystems. Jim is at the forefront of practitioners developing novel solutions to these issues in this field.

As a consultant, Jim is recognized for using innovative approaches in the planning and execution of projects that are grounded in practical applications of existing and emerging technologies. His clients include federal, state, municipal, and industrial sites throughout the Southeastern United States. He specializes in the characterization of dense non-aqueous phase liquid (DNAPL) source areas using the latest, proven assessment tools plus remediation strategies to remove or neutralize solvents.

Jim has served as Geosyntec's engineer-of-record on a number of key projects at NASA's Kennedy Space Center, including the largest known DNAPL site in Florida. He also has served as Geosyntec's lead engineer on projects in Florida's Dry Cleaning Solvent Cleanup and Hazardous Waste Program, during which he has completed assessments or remedial designs for more than 30 solvent, metal, and petroleum-impacted sites.

To advance the state of the practice, Jim's work emphasizes on the application of techniques for the design or optimization of soil and groundwater treatment systems deploying sustainable remediation approaches. Examples include his efforts to transition sites from energy-intensive, mechanical treatment systems to passive, in situ biological treatment and flux control approaches. He also designed and created a solar-powered groundwater recirculation system at Kennedy Space Center for the enhanced in situ treatment of a chlorinated solvent plume.
