Until Vi gets back to you directly I can help a little! I discussed this with her before and she said to think along the lines of an oil spill, but even more corrosive and toxic, like we see in the movie.

Containment efforts would be as big as cleanup efforts, and there would be lots of dead wildlife to deal with. Anything that's been touched by kaiju blood might be structurally compromised, so cadets would have been briefed to be careful of buildings, etc.
