The Big Story

Wed. Oct 30, 2019

The chemical industry is growing rapidly in Louisiana at the same time that the state is backsliding when it comes to toxic levels of cancer-causing chemicals in the air. Along with Local Reporting Network partner The Times-Picayune and The Advocate, we investigated.

Welcome to “Cancer Alley.”

In a Notoriously Polluted Area of the Country, Massive New Chemical Plants Are Still Moving In

Data from an EPA model indicates that communities along the lower Mississippi River corridor already face severely elevated cancer risks from industrial activity. Massive new chemical plants are slated to be built there anyway.

I’ve Investigated Industrial Pollution for 35 Years. We’re Going Backwards.

Decades ago, Mark Schleifstein and his colleagues exposed environmental threats coming out of industrial plants all along the Louisiana section of the Mississippi River. A lot of those plants never went away, and even more are moving in.

How We Found New Chemical Plants Are Being Built in South Louisiana’s Most Polluted Areas

ProPublica and The Times-Picayune and The Advocate investigated the potential cancer-causing toxicity in the air. Using EPA data, public records requests and more, we found that some of the country’s most toxic air will likely get worse.
