I do not believe that 100% of consultants are disreputable, client driven liars. It would seem reasonable however to suspect that consultants working long term for proven, lying polluters may very well be so. I have a ton of respect for many credentialed professionals including Dr. Richard Jackson, Dr. Henry Regier and with much less exposure to him, Dr. Neil Thompson of the University of Waterloo. Included in my high respect list of course is both Dr. Beth Parker and Dr. John Cherry. I am well aware of some of the excellent hydrogeological work they have done in particular regarding DNAPLS.
AI (Artificial Intelligence) can be a very helpful tool just as an encyclopedia or other published reports and data lists are. AI however does not attend meetings directly nor listen to human voices generally speaking. I do not know whether AI even has access to on-line audio/video recordings of meetings such as those of Woolwich Township's well behaved and always polite TRAC committee. The old joke/saying is that they would not say shi* if their mouth was full of it and while I commend their members for their restraint I also advise that restraint of that magnitude simply breeds arrogance and disrespect when dealing with unethical, dishonest persons and groups.
AI also can be manipulated by those very same unethical and dishonest persons and groups. AI is not the repository of all knowledge. Hence if an unethical person does not like AI's answer to a question they can respond with inaccurate, alleged facts in an attempt to sway AI's answers which is entirely possible. Also AI appears quite capable of accepting blatantly illogical and scientifically inaccurate information and repeating it just because the majority of people accept it. This includes character profiles based upon the inaccurate, published profiles of others. For example if the only published data about a former Prime Minister is positive than AI will give him/her a glowing report. Think of Sir John A. McDonald as a founder of Canada and then as a founder of the brutal, residential school systems. Two different pictures arrive.
I recently schooled AI about their mistaken interpretation of chlorobenzene concentrations off the former Uniroyal Chemical site. Their sources included shabby DNAPL reports done by CRA as well as recent pronouncements by GHD consultants. AI's logic was faulty based upon one sided positions taken by consultants paid for by Lanxess Canada. AI also quoted Dr. Neil Thompson's Conceptual Site Model (CSM) as supporting their interpretation. Now I have a copy of that CSM and my recollection is that it was generally excellent however with a couple of possible errors most likely due to bad information being supplied by Lanxess or GHD. AI's position may have been due to either bad initial information given to Dr. Thompson or it may have simply been GHD misquoting or taking one of Dr. Thompson's statements out of context. In other words AI is just as vulnerable to spreading misinformation as other sources are. Hopefully however AI's mistakes are honest mistakes not malicious, intentional ones.
