The state of Virginia is going to sue the US government demanding US $1.5 million as its share ofthe money spent so far and for future expenses required for cleaning up the pollution caused by a rayon fibre factory. The state has alleged that the federal government was aware of the pollution problems at the factory for years but it did nothing to check them. The factory was closed down due to financial and environmental problems in 1989, leaving behind a vast toxic sludge on the banks of the Shenandoah river. So far, the federal government has spent US $25 million to clean the factory site.
