This ProPublica story is good reporting on 3M's sociopathic, and ecocidal, commitment to contaminating all the water on earth…but the "crusading investigative reporter" narrative might mislead you into thinking this scandal hasn't been burning in public for decades (see e.g., from 2016, https://www.nytimes.com/2016/01/10/magazine/the-lawyer-who-became-duponts-worst-nightmare.html ) The missing part of the story is the weakness and even complicity of the regulators.
