There is a relatively new threat to the health of Americans and Canadians. The flourishing future for all people, which our religious tradition envisions, is threatened by PFAS chemicals, which contaminate our water supplies and exist in various consumer products. Vulnerable and frontline communities, for whom we are particularly called to care, are especially affected. Of the approximately 5000 PFAS chemicals produced, only perfluorooctanoic acid (PFOA) and perfluorooctanoic sulfonate (PFOS) have been studied extensively.
