we have a small airport near us (#Livermore, California) and we have elevated #PFAS in half of our wells. Local government types say the other half of them are fine (as if underground water exists in little well-shaped silos).

To the best of my knowledge, no one rests for PFAS in blood samples.

Of course, until quite recently, leaded aviation fuel was allowed for these small airports. So, look over there! Nothing to see here.
