I experienced a feeling of serendipity when reading the article on the contaminated ground of the Olympics site and the aerial pictures of the old Wembley Stadium, site of the last London Olympics (NCE 1 March).
Sir Owen Williams, who was responsible for the original Wembley Stadium, used to say that Wembley was chosen for its proximity to London and for the fact that it was outside the area subject to London building acts and bylaws.
Similarly, the site of the 2012 Olympics was also outside the former London County Council control, hence the many, so-called noxious, industries located there. They were close to the big London markets and the docks for their raw materials, and to a large open wasteland which acted as their dustbin.
