        Welcome to part 4 of our blog series “The Problem of PFAS”. If you are just tuning in, you might want to take a look at the previous blogs of this series as we provided background on the PFAS controversy (Part 1), a review of the regulatory guidelines for  monitoring PFAS contamination in the environment (Part 2), and most recently, a look at which analytical method might work the best for your lab (Part 3).

It was when I was first exposed to EPA method 1664B. It stated right in the introduction it is a performance-based method.
