For PFAS, hazardous designation is not a ban
News
15 Oct 2019 | EWG News
Designating PFAS as “hazardous substances” is critical to cleaning up legacy contamination [and is different than a ban]. There are currently 761 substances on the CERCLA hazardous substances list. Almost 700 of them have been on the list since the law was passed in 1980. An EWG analysis found that at least 599, or 79 percent of these chemicals are likely still in active use in commerce today. What’s more, 339 of the CERCLA hazardous substances chemicals, or 44 percent, are not only in production, but likely produced at high volumes.
