The average US citizen has a large load of PFAS in their blood[1] from clothing, carpet, water and other sources. The levels have dropped a great deal in the last 20 years but it's unlikely you've increased your levels much beyond what you already had from other sources. [1] https://www.atsdr.cdc.gov/pfas/pfas-blood-testing.html https://www.atsdr.cdc.gov/pfas/pfas-blood-testing.html The blood serum levels reported by CDC are staggering. As an example, I have a well and it's in a contamination plume of PFOS and PFOA. The EPA certified laboratory measured level two years ago was 11 ppt (parts per trillion.) The CDC measured 2.1 ug/L of PFOA (only) in the blood of over 2000 people in 2014. That's 2,100,000 ppt; 5 orders of magnitude higher than my 'contaminated' water.
