Recycling on the Olympic Park is helping to reduce traffic on the surrounding roadsThere have been nearly 3,000 site investigations carried out into contamination on site since October 2006 with nothing unexpected uncovered. Industrial contamination that was found on site included oil, petrol, tar, cyanide, arsenic and lead, as well as some very low-level radioactive material.
The contaminated soil has been cleaned and reused on site using innovative techniques including soil washing and bioremediation – a technique that uses bacteria, fungi and other microbes to clean the soil.
The clean-up process began three years ago and enabled construction to start on or ahead of schedule on all of the permanent Park venues. The ‘big build’ is now well underway with venues coming out of the ground. Work also continues on the 21 bridges, roads, a new energy centre and utilities network, and transport infrastructure. This will not only benefit the Games, but the communities that will live and work in the area after 2012.
