Actually. We don't know anything. Or rather, we only know what she chose to present, already colored to match her conclusion.
How do you know some pertinent information isn't missing from her account?
>But: she gathered environmental data, and reports completed prior to her moving there had already concluded that "VOCs were above residential limits
So what? Let's say VOCs are above residential limits (and I'm not sure about that given that untrained people using consumer sensors are liable to get a fair share of false results or improperly interpreted results) ... BUT OK ... how does she (and you) know that this is what is causing her symptoms?
> In other words, there are a number of external reasons to think this is plausible.
I wouldn't go that far. All we can really say is that she is experiencing symptoms. Those symptoms could be a result of anything (or nothing). Nothing she says passes the smell test because she's engaging in very typical conspiracy theory thinking. She decided that the cause of her symptoms is living in an apartment built on reclaimed land for very flimsy reasons. And then she went around cherry picking evidence to support that conclusion.
I mean, she wrote a message to her apartment management company that stated: "The chemicals are still pouring out full blast" ... are they really? The management company sent an inspector to test for chemical and gas leaks ... and nothing. She hired her own consultant to perform the tests, and that person found nothing... and on and on and on.
She sounds EXACTLY like the people who are convinced cell towers are poisoning them. Every piece of countervailing is ignored by her ... just like a conspiracy theorist. She strikes me as someone who spiraled into this rabbit hole and got absolutely convinced this one thing (out of infinite number of possible things) is causing her symptoms.
Needless to say, I'm skeptical.
