A lot of products contain toxic PFAS. Some of these "forever chemicals" are ending up in sewage that is turned into fertilizer.

A MARTÍNEZ, HOST:

The water from our sinks, showers and toilets contain the chemicals known as PFAS. As WBUR's Barbara Moran explains, all those so-called forever chemicals are going into wastewater treatment plants. The question now is, where do they go from there?

BARBARA MORAN, BYLINE: It's barely sunrise, and I've already put a lot of stuff down the drain - shampoo, cold coffee, soap, all kinds of stuff.

LAURA ORLANDO: What gets into wastewater is just about everything that we use in our society.
