Is it possible to divert contaminated soil onto a green roof?

By admin on Thursday, April 1st, 2010 | 1 Comment

I am working on a brownfield site contaminated by industrial soil (mostly inorganic materials like metals). I wonder if there is any precedent building/project that divert the contaminated soil on a site and apply it onto the green roof, and remediate the soil through the use of plants. If so, does it do any harm to the occupiers?
I have heard of a method called "Phytoremediation" that have plants mitigating metals.

http://en.wikipedia.org/wiki/Phytoremediation

contaminated soil containing metals will be very, very slow to be absorbed by plants…and the plants would be toxic in themselves. You cannot burn them, that would release the metal to the atmosphere. You just cannot get rid of metal as you do organic toxins…metals are here to stay and are best handled through chemical means of collection and concentration. This is not something to play with…arsenic, strontium, etc. may well be in that soup!
