A so-called "forever" chemical recently declared carcinogenic by the WHO has been found in Australia's tap water at 140-times the maximum level allowed in the United States.

PFOA is allowed at much higher levels in Australian water, since the Biden administration dramatically lowered its safe limits for drinking water. A new documentary on the Stan Network - called 'How to Poison a Planet' highlights the dangers of such chemicals, and premiers later this month.

Guest: Carrie Fellner, investigative journalist for the Sydney Morning Herald; features in the documentary 'How to Poison a Planet'
