Dan Rodricks: For the sake of environment and health, back away from ‘better living through chemistry’

What do we do about PFAS? There seems little doubt that scientists will discover more of these “forever chemicals” during the testing of Maryland farmland and Chesapeake waters. What do we do when we find them? Can we destroy a “forever chemical”? The term is scary, suggesting a harmful substance so durable it can’t be washed away. PFAS are chemical compounds found in our homes, in the land where cows graze and where farmers grow our food, in the waterways where we harvest fish. PFAS are “biopersistent” and “bioaccumulative,” meaning they hang out and build up over time.
