"The 3M Company has vowed to stop manufacturing PFAS chemicals by the end of 2025. The FOX 9 Investigators reviewed hundreds of hours of video depositions that shed new light on how company executives and scientists responded after first learning about the widespread contaminations.

What's next:

The 3M Company has vowed to stop manufacturing PFAS chemicals by the end of 2025 and argues it has been a leader in addressing PFAS. A new FOX 9 documentary "Everywhere & Forever: Blood. Water. And the Politics of PFAS" will reveal the inside story of how the company withheld early research into PFAS contamination and how a state regulatory agency shut down its own research. You can watch it on FOX 9 and FOX LOCAL at 8 p.m. on July 31."
