The Science on PFAS: Rebuttal to 3M’s Claims

Comment are off

By Environmental Working Group

For decades, 3M was a leading producer of the toxic fluorinated chemicals known as PFAS. As early as the 1950s, 3M’s own studies showed that PFAS chemicals built up in blood, and by the 1960s, 3M’s own animal studies showed the potential for harm. Yet 3M continued to produce PFAS chemicals without notifying its employees of the risks.

Since then, there have been hundreds of studies identifying the health risks associated with PFAS chemicals. Much more is also known about the wide spread of PFAS contamination. From federal and state data, EWG has identified more than 700 sites contaminated with PFAS chemicals.

Despite the well-documented safety concerns associated with PFAS, 3M is doubling down on misleading claims about the chemicals and its involvement in the current contamination crisis. In the wake of pending state and federal legislation, and pending lawsuits against current and former PFAS manufacturers like 3M, the company has created a propaganda site downplaying the risks of PFAS.

EWG scientists reviewed the claims of 3M and responded, using the latest, unbiased research on PFAS, to set the record straight. (All 3M statements come from https://www.pfasfacts.com/, accessed on Sept. 4, 2019.)
