What happens if bottled water was used?
The CIA and FBI spent a lot of money on water isotope analysis.
I don’t know more than what the published articles say and would ask only that the FBI explain how the isotope ratio analysis corroborates or undermines their conclusion. If it corroborated it, I would have thought that they would have included it in the October 2007 affidavit.
For different purposes, a year or two ago I tested many dozens brands of water at a local lab — personally collecting them. In my experience, even the major brands (by Coke and Pepsi) are bottled not far (for example, in the same state or an adjacent state). That’s because of the transportation costs. I mentioned this to one of the isotope ratio researchers and heard back from him — but I never heard back from the main researcher, Dr. E, when I posed the question you ask. So I can’t give you what his answer would be.
I ordered water from all over the world. One Mexican water sold by a major company tested high for arsenic (way above legal limits). A recall was done throughout the Northeast for a different contaminant. Here, one would want to know whether any bottled water had high levels of silicon.
