Tubbs Road Allotments

I have come across a potentially big problem with the proposed food growing project between Tubbs Road and Willesden Junction. The Well London project was intending to use the land for a series of grow bags. Unfortunately a soil test has shown heavy metal contamination. I am still trying to find out whether this is fixable. There are lots of sites in London with previous industrial or railway uses, so it is not out of the question. The other problems with the Council taking over the site are mainly legal and money based, although apparently there is also some Japanese knotweed there.
