248. Mariah Blake with Mónica Guzmán: A Legacy of Chemicals & Cover-Ups

From Silent Spring to Erin Brockovich, people have been captivated — and devastated — by stories of harmful chemicals and the many ways that they have altered and even ended human lives. From investigative journalist Mariah Blake comes a new book that recounts a small town being poisoned, a corporate cover up, and a grassroots movement to fight back.

In 2014, after losing several friends and relatives to cancer, an insurance underwriter in Hoosick Falls, New York, suspected that the local water supply was polluted. When he tested his tap water, he discovered dangerous levels of “forever chemicals” (synthetic chemicals that are resistant to breaking down and can lead to adverse health and environmental effects). This set off a chain of events that revealed at least 100 million Americans’ drinking water was tainted. The discovery of bad water was a shock to some, but perhaps more shocking was the discovery that the United States government and the manufacturers of these toxic chemicals — used in everything from cookware to lipstick to children’s clothing — had known about these hazards for decades but had hidden them from the public.

In her new book They Poisoned the World, investigative journalist Mariah Blake tells this story, tracing its roots all the way back to the Manhattan Project and through the postwar America.

Drawing on years of reporting and tens of thousands of documents, Blake weaves the history of forever chemicals with the story of how a lone village took on the chemical giants all the way to the nation’s capital — and won.
