Thirty years ago today, on July 3, 1995 (June 6, 1995), Sydney's concealment of toxic contamination of the Olympic Village was revealed. The vicinity of the Olympic Village for the 2000 Sydney Olympics has long been contaminated with toxic chemical residue, and it will cost tens of millions of dollars to remove the hazard. Sydney Olympic Village is located in Homebush Bay on the western outskirts of Sydney, which used to be a naval warehouse and an industrial area. The New South Wales government today released an official document saying the pollution problem was concealed when Sydney won the Olympic bid two years ago. The document, which was completed last year, said: "The pollution problem in Homebush Bay appears to pose a greater threat to health and the environment, but this problem has not been made public." The pollution problem was the conclusion of a working group's investigation in May 1992, but this conclusion was not sent to the state government. Apparently this move was concerned that any spread of the pollution problem would be detrimental to Sydney's bid to host the 2000 Olympic Games, because the main idea and decision of the Sydney Olympic Committee to win the right to host the Olympic Games was to host a "green Olympic Games". It is understood that Sydney will remove these toxic chemical filter residue pollutants. But according to the New South Wales government, the cost of removing these pollutants is estimated to be as high as $40 million. The village on Homebush Bay will host 15,000 athletes and officials from around the world during the 2000 Games, and will be converted into a residential area for 5,000 people after the Games.
