Sure but here's the problem: all of those chemicals are biodegradable. Most information about what is happening is basically "there was a large release of a non-environmentally persistent contaminant" which just plain isn't going to hit the fears right for people.
Vinyl chloride doesn't hang around[1]: nothing with an ethene-double bond is going to be good for you if you ingest it, but it's not stable because that's why it's used: UV light and most biological processes will degrade it very quickly.
Would you want to bathe in it? No. You also wouldn't want to be near a really large, concentrated release but it's not perfluorocarbon, nor heavy metal.
Which is to say, you could go look these things up right now - this information is not even slightly secret. But it is both a serious situation, and one that isn't what the "why isn't this being covered" people want it to look like.
