A New Hampshire town finds out its water has been contaminated by a chemical. The most basic question — whether the water is safe to drink — doesn’t have a clear answer. Nobody seems to know much about this so-called forever chemical, which is weird… because all of this has all happened before. From the Document team at New Hampshire Public Radio, Safe to Drink is a four-part series about a water contamination story that keeps repeating in town after town — and about the people who fought for answers through a maze of chemistry, regulations, and illnesses. You can binge the whole series now: subscribe to Safe to Drink on Apple Podcasts, or check out their page on NHPR’s website.  Learn more about your ad choices. Visit megaphone.fm/adchoices
