With the 2012 summer Olympics approaching, London is going for gold in greening up the future site of the games. According to the U.K.’s Environmental Agency, clean up of the massive area has now been completed and construction can begin.
Getting the site ready for use was no small feat, especially considering that much of the land was previously used for industry, chemical storage and factories, leaving the area polluted and contaminated. Working with the Olympic Delivery Authority and the London Development Agency, the Environmental Agency used five soil-washing machines to decontaminate two million tons of polluted soil. By scrubbing the soil, the agency was able to reuse as much as 95 percent of it onsite instead of having to truck out dirty soil and bring in clean soil to replace it, saving on costs while also reducing the environmental footprint.
The cleanup included removing concrete walls and invasive species from the River Lea in order to make it more habitable to local wildlife, and 110 acres of land was converted into woodlands, grasslands, ponds and reed beds. The wetlands will also provide a space for flood water to run off, thereby reducing the risk of flooding to 4,000 homes in the area.
Darren Johnson, Green Party member of the London Assembly, points out that still more could have been done for the environment. He would have preferred to see officials accept a bid from Nissan for an all-electric fleet of vehicles (BMW won the contract instead). The Games also fell short of its target to generate one-fifth of its power from renewable energy, ending up somewhere closer to only 11 percent.
