Olympic Stadium, London
The area that is now home to the Olympic Stadium was once occupied by bone works, oil refineries, soap works, tanks, chemical works, warehouses.
The 2012 Olympic Park covers around 245ha (big enough to fit 357 football pitches) in the Lower Lea Valley, London. The first phase was to remove 52 overhead power pylons, re-route cables into two 6km tunnels and provide new water and power networks.
Contamination from over 200 years of industrial use included oil, petrol, tar, cyanide, arsenic and lead, as well as some low level radioactive material. In total around 80% of 800,000 cubic metres of contaminated soil was cleaned and re-used on site, and more than 20 million gallons of contaminated groundwater was treated.
Over 200 buildings were demolished including offices, warehouses, chemical works, food-processing facilities, concrete plants, bus garages, railway sidings and residential sites.
A clean up of this scale historically would have taken in the region of 5-15 years to complete. The Olympic Park took less than 3 years.
Contaminated land, if left untreated could be hazardous both for those using the land and the wider environment. It can also affect the value and future development of the site. If you are intending to purchase or use land which has a history of industrial usage it is wise to commission a professional environmental check for potential contamination.
