Given they were looting Mariposa, presumably FEV was taken from there to Navarro to Poseidon. Also, we see they're conducting experiments in the base as well as on the oil rig. Hence why you can murder the doctor in the soundproof room.
On a Deathclaw, there's no mention of FEV.
EDIT: I need to verify this, as I may be incorrect about it.
Most but not all of their records. As for using the Purifier to distribute the virus, it's a virus not a poison so it'll be distributed through the ocean. But maybe not. Maybe John Henry Eden may actually just intend to wipe out the mutations in the Capital Wasteland so they can rebuild America there and go outward as the Maxson Brotherhood of Steel does to the Commonwealth.
I doubt that one vial of FEV would infect the ocean. The FEV on the rig was modified to be airborne and they likely had enough of it to do the job.
I will say, though, that the dropping FEV into the vents and killing all of the non-powered armor Enclave citizens is probably non-canonical in Fallout 2 as there's clearly a large civilian population necessary to rebuild the Enclave. Presumably, they evacuated the Oil Rig and were taken to Raven's Rock.
To you, maybe. Even without the vents method most were killed when the rig exploded. You can't just evacuate hundreds of people in a small amount of time.
We have no evidence of them, though, and it's entirely possible Gannon and the Remnant are the only non-Enclave forces. I admit, though, I hope we'll see an Enclave conspiracy ala Captain America and the Winter Soldier some day.
It's mentioned by loading screen.

Though they were a powerful force in the west decades ago, the Enclave has not been seen or heard from in the Mojave Wasteland for years. Members who were not hunted down are believed to have traveled east - or successfully integrated into the NCR.
No way they'll be able to come back in force though. They were decimated on the rig, they were decimated in Navarro and the East Coast Enclave is dead as well.
It does mean some kind of contact was going on between John Henry Eden and the Enclave, though.
After the rig explosion maybe, but nothing says they were while Richardson was alive. Why would they listen to Eden anyway? The President would already have advisors, he'd have no need for some voice on the East Coast.
I honestly think Fallout 3 is the far more mature and non-humorous game. It's very moving to me and sad. Lots and lots of focus on the tragedy of nuclear war versus SCIENCE and FUN. I say that as a huge fan of SCIENCE and FUN.
In what way is it more mature? I really would like to know how for example Eden's self-destruction is more mature than the Master's suicide.
The same could be said about all of Fallout 3.
But on a more serious note, sacrifice is a theme.
Your father abandons his research to raise a son in a Vault. He sacrifices his life's work of restoring clean water to the wasteland to raise you in a safe environment.
You can take it further and say that Harold can sacrifice himself for the good of the wasteland. Leaving him alive takes away his chance of a peaceful death, but this can be sacrificed in order to help others.
You can either agree that it is a theme, or you can disagree which shows that Bethesda can't write for shit because they can't even get their themes right.
Let's not forget your father sacrificing (or rather pissing away) his and his child's safe life in Vault 101 and then actually killing himself to stop the Enclave from using the purifier, even though his death is totally pointless given it wouldn't have worked anyway without the GECK and chances are the BOS would have taken it back.
