Okay, so it will take 3 sticks of SEALS rather than the 2 I previously thought.
Naaah... Any SF unit would be better used elsewhere. Just strap Michael Moore to a barge, anchor it off of the western, up-wind end of the island and feed him pickled eggs and pinto beans for 5 days. Instruct all friendly personell to stand clear of the biohazard area for the following 5 days. Allow 5 more days for hazard to clear. Perform mop-up work in full NBC gear, starting at western end of the island and working east. :-)
