Two millions tonnes of soil cleaned on 2012 site

- 13 June 2010

2012 Olympic chiefs have revealed that now nearly two million tonnes of contaminated soil has been cleaned for reuse on the games site at Stratford.

It is, they say, the largest ever soil-washing operation in the UK in which five giant machines have been in use on a million cubic metres of soil contaminated with oil, petrol, tar, cyanide, arsenic and lead.

Also over 98 per cent of demolition materials from on-site industrial buildings that have made way for the sports spectacular have been recycled

In all the 'green clean-up' was over 2.5 sq km of land much contaminated through decades of industrial use.

Work began nearly four years ago and the project has consistently beaten its tough sustainability targets.

The is now also a map from the Olympic Delivery Authority showing the 'Green Build' of the Olympic Park venues and parklands and details of the London 2012 sustainable transport plans.
