Tom Krug is a Principal Environmental Engineer based in Ontario focused on the evaluation and development of innovative strategies and technologies for remediation of complex contaminated properties for Fortune 500 companies, agencies of the U.S. Department of Defense (DoD), and NASA.
Tom specializes in taking new technologies for remediation groundwater, sediment, soil and other waste from the early development stage to successful field scale application, and adapting new and conventional technologies to solve client's real-world problems. He works closely with Geosyntec's microbiologists, geochemists and hydrogeologists and uses his engineering expertise to further enhance the applications of technologies such as in situ bioremediation and redox manipulation for treatment of chlorinated solvents, perchlorate and metals-impacted groundwater and mitigation of potential risks associated with chemicals in sediment using caps and cap amendments. Tom's work includes engineering design for in situ bioremediation of groundwater, treatment of DNAPL source areas, in situ treatment of metals and evaluation of biodegradation processes of complex chemical mixtures and emerging compounds. He has also evaluated and demonstrated technologies for mitigation of potential risks associated with PCBs in building materials.
Experienced with conventional remediation technologies, Tom consults clients regarding the design and operation of groundwater extraction and treatment systems; installation of collection trenches to enhance the removal of DNAPL and dissolved contaminants; management of risks at complex sites with chlorinated solvents and metals; and soil vapor and multi-phase extraction systems.
He is a pioneer in the development, demonstration, and application of zero-valent iron (ZVI) permeable reactive barriers (PRBs). He aided researchers at the University of Waterloo in the testing and design of the first full-scale ZVI PRB installation in 1994 and managed the pilot-scale testing and design of the first ZVI PRB at a Landfill Site in 2000. Through his applied research work in collaboration with NASA and DOD agencies, he has extended the applications of ZVI technology to include the use of emulsified nano-scale zero-valent iron (EZVI) for treatment of chlorinated solvent dense non-aqueous phase liquids (DNAPL) source zones.
