- bscphil 4y agoThe map reminds me of this infamous plot [1]. Look at how many more points there are in North Carolina, New Jersey, and Massachusetts than surrounding states. Naively we would conclude that these states have way more PFAS contamination. But maybe they are just considerably better about testing for and reporting it?
