'Forever chemicals' can have far-reaching consequences, need more regulation in Canada, scientists say
News
7 Nov 2020 | CBC Radio Canada
Unlike pesticides or pharmaceutical drugs, a significant portion of the more than 6,300 different types of PFAS on the market have little to no data on their use, toxicity and chemical structure and are not currently regulated or restricted in Canada. Also, a restriction or a ban of a specific substance does not automatically mean that its replacements do not pose similar or other harm.

Because the City of Newburgh, NY switched off its main drinking water source after the discovery of toxic PFAS in Washington Lake, it may be penalized and ultimately left out in the next round of priority cleanup site selections, as it is no longer considered a drinking water source. Without knowing why toxic water is still flowing from Stewart Air National Guard Base and where it is flowing to, the United States Air Force can’t find a permanent fix.
