The competence of DuPont is not in question, they existed before the EPA. When the EPA was formed, DuPont should have informed them of all the data they had on potentially toxic chemicals like C8, but they didn't. Which is why the 20 year lawsuit and testing of 70 thousand people's blood was necessary to determine if they were harmful or not.
It has been conclusively proven that C8 is harmful to humans. Combined with its extremely long lasting nature, this is a recipe for disaster. Trump and RFK should be taken to task over this, but Biden is not without blame either.
Filtering C8 is expensive and most water treatment plants are not adequately equipped for it. Trump's budget cuts worsen this situation. However the Biden administration's delusional economics are also partly to blame. You can't afford to import infinity people and also filter from the water all the hazardous chemicals that our great nation has produced for profit.
Ignoring reality is perilous.
