What this does not tell you
These are entry-point results for the system, not one tap. Water mixes between sources, sits in mains and passes through household plumbing. A certified lab test of your own tap is the only thing that answers what you drink, and it is the only route at all for a private well.
How to test your tap waterIf you want to treat it
Reverse osmosis and properly specified activated carbon remove most PFAS at the tap. Certification to NSF/ANSI 53 or 58 with an explicit PFOA and PFOS claim is what separates a PFAS filter from a taste filter.
