Submitting comments on the World Health Organization (WHO)'s draft guidelines for allowable levels of PFOA and PFOS contamination in drinking water, the Environmental Working Group (EWG) has expressed that the proposed guidelines ignore WHO's goal of prioritising public health. It raises the possibility of scepticism regarding the dangers of PFOA and PFOS on human health. It places a strong emphasis on lowering the cost of chemical removal from water. It also claims that there are too many scientific questions around PFOA and PFOS for it to be possible to determine what amount of exposure would be deemed safe. The document's emphasis is on minimising the cost of removing chemicals from contaminated water rather than on the health hazards posed by PFAS. This strategy defends the polluting companies that have been releasing PFAS for years, the EWG added in its comments.
