Revere Water Department (MWRA)

NOTE: Revere Water Department (MWRA) purchases water from Massachusetts Water Resources Authority (MWRA) which is required to test for perfluorooctanoic acid (pfoa). Sample information shown below was taken by Massachusetts Water Resources Authority (MWRA).

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

State and national drinking water standards and health guidelines

EWG Health Guideline 0.007 ppt

The EWG Health Guideline of 0.007 ppt for PFOA was proposed by California Office of Environmental Health Hazard Assessment as a public health goal, the level of a drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.

EPA Proposed Maximum Contaminant
Level (MCL) 4 ppt

The proposed legal limit for PFOA is 4 ppt, based on studies on people, including children, showing cancer risk.
