Fairfield Water Department

NOTE: Fairfield Water Department purchases water from Passaic Valley Water Commission which is required to test for n-methyl perfluorooctanesulfonamidoacetic acid (nmefosaa). Sample information shown below was taken by Passaic Valley Water Commission.

N-methyl perfluorooctanesulfonamidoacetic acid (NMeFOSAA) is a member of a group of perfluorinated chemicals used in many consumer products. NMeFOSAA and other perfluorinated chemicals can cause serious health effects, including cancer, endocrine disruption, accelerated puberty, liver and immune system damage, and thyroid changes.

State, National, and Health Guidelines for Drinking Water

EWG Health Guideline: 1 ppt

The EWG Health Guideline of 1 ppt for NMeFOSAA 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.
