Our guest on this episode is Adrian Heggie. Over the past decade Adrian has developed an amazingly simple method for the delineation of sub-surface hydrocarbon plumes (chlorinated or not) by measuring the aboveground concentration these plumes cause. His method is fast, accurate, inexpensive and most of all, does not require any invasive ground work. If you think this sounds too good to be true, this chat will convince you otherwise. Adrian showcased his research at the recent Chlorinated Hydrocarbon Symposium held in Adelaide. Among the audience was Gunnar, who, like many others, was intrigued by the presentation. In this chat the two of them delve into Adrian's research and shed some light on how hydrocarbon contamination reaching the surface can be captured and measured (not a good pun, but still intended). https://au.linkedin.com/in/adrian-heggie-b7767336 The episode was recorded on 28 March 2024.
