State and national drinking water standards and health guidelines

Health Guideline 1 ppt

The health guideline of 1 ppt for perfluorononanoic acid 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 PFCs most widely detected in drinking water. This health guideline applies to the entire class of PFCs detected in water.
