EWG Health Guideline: 1 ppt

The EWG Health Guideline of 1 ppt for N-EtFOSAA was defined by EWG as 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.
