Perfluorononanoic acid (PFNA)
Cape May Point Borough Water
NOTE: Cape May Point Borough Water purchases water from Cape May Water & Sewer which is required to test for perfluorononanoic acid (pfna). Sample information shown below was taken by Cape May Water & Sewer.
Perfluorononanoic acid, otherwise known as PFNA or C9, is a PFC similar in function and use to PFOA. These chemicals were used in the production of non-stick, stain repellent and chemically inert coatings. Click here to read more about perfluorinated chemicals.
