2012 Olympics Stadium Highly Contaminated

£12.7 million so far has been applied to clean up the 2012 Olympics London Stadium highly contaminated by deadly chemicals

The land located in east London on the banks of river Lea, previously under the ownership of Banner Chemicals Group.after environmental assessments, to contain a plume of vinyl chloride -- a breakdown product of chlorinated solvents, one of the main chemicals handled by Banner -- in its groundwater.

"Vinyl chloride is one of the most toxic organic compounds found in groundwater, and it can cause damage to the liver and nervous system.", it has been revealed by Dr Jason Gerhard,a hydrogeologist based at the University of Western Ontario in London, Canada.

According to the Environmental Agency, the process will continue long after the Games as the contamination on the site is so severe

Stuart Hayes, a hydrogeologist at the Environment Agency said ""We thought that this would be a dirty site but it turned out to be much worse than we expected, grossly contaminated"

“So far, only the topsoil has been cleaned. The next and much more difficult stage is to clean up the deeper pollution.”

The director of Banner Chemicals, Colin Boyle, said, "We take our responsibilities seriously. We seek to implement best practice industry standards and to comply with all of the regulations that relate to installations of the kind we operate.”

“You mention an incident involving some chemicals but I do not know what you are referring to and so you will appreciate that I am not in a position to comment," he added.

“The £12.7m cost of the clean-up, revealed in a Freedom of Information Act request to the Olympic Delivery Authority, should not be covered by taxpayers.” said by Darren Johnson, chairman of the London assembly environment committee
