So, the elephant in the room at this stage of the thing is this:
Why don't you just *put this stuff in a building*, and, y'know, never
Yes, you'll probably have to build it to CO grade standards, but that
isn't exactly rocket surgery, and it seems to me that you peel
3 or 4 layers of crap off the top doing it that way.
Unless you're in, say, the Philippines, I can't see the advantage of
burying all that stuff underground on a campus-scale deployment.
