Rio Tinto's wholly-owned Kennecott subsidiary is by far the biggest airbourne polluter in the United

Rio Tinto's wholly-owned Kennecott subsidiary is by far the biggest airbourne polluter in the United States. It is also responsible for the dumping of contaminants which have affected no less than 72 square miles of underground aquifers in Utah.

A proposal by the company to "clean up" these inherited and created wastes may, according to unionists, environmentalists and local communities, simply shift the problem overground. This will penalise taxpayers while rewarding the company with rebates. The campaigners demand that Rio Tinto/Kennencott recycle toxic metals in the waters, find a secure location for permanent waste disposal - and pay the bill!
