Health Risks
The EWG Health Guideline of 1 ppt for 8:2 fluorotelomer sulfonic acid (8:2 FTSA) was defined by EWG based on studies by Phillipe Grandjean of Harvard University and many other independent researchers who found reduced effectiveness of vaccines and adverse impacts on mammary gland development from exposure to PFOA and PFOS, the two PFAS most widely detected in drinking water.
