Jim discusses remediation technologies that target source zones containing Non-Aqueous Phase Liquids (NAPLs), such as solvents and hydrocarbons. He makes the point that even under highly controlled research conditions, it is unrealistic to expect complete source removal.
Jim recently retired as a Professor at the University of Waterloo and remains involved in research and graduate teaching as an Emeritus Professor. I had the good fortune of having Jim as my PhD Supervisor, a “few” years back.
