Contamination: The unfolding scandal of toxic water in Australian communities.

It's one of the biggest environmental scandals in Australian history – harmful chemicals leaching into the ground and waterways, contaminating water relied upon for drinking. These chemicals are the toxic legacy of fire-fighting foam used for decades on Defence Force bases and other sites around Australia. The impact on those affected is profound. Some rely on water supplies trucked in by Defence contractors. Others are trapped financially, unable to sell, with their homes officially designated as a contamination zone. All worry about the implications of exposure to these chemicals.

Four Corners has discovered that the scale of the problem is continuing to grow as more and more sites around the nation are being tested for contamination.
