Olympic clean-up is complete, says Environment Agency

Work to clean up the Olympic site and create the largest urban park in Europe for more than 100 years has been completed, the Environment Agency said yesterday.

An area the size of 297 football pitches, much of which was polluted, has been cleaned up. About 300,000 wetland plants and 2,000 native trees have been planted and five miles of the River Lea restored. The Environment Agency said it had helped decontaminate two million tonnes of soil.
