Louisiana serves as a terrifying example of what can become of a state that shortchanges science and environmental regulations to boost industry and infrastructure.

If you’re visiting New Orleans and want to see something truly amazing, take your beer or daiquiri to-go and walk a few blocks past the Superdome—you’ll find a school being constructed on an old waste dump.

“All the toxins from the landfill are still there,” says toxicologist Wilma Subra. These toxins include lead, mercury, and arsenic, exposure to which can lead to reproductive damage, and skin and lung cancer. Even more astonishing, Subra says hundreds of schools across Louisiana have been built on waste dumps. Why? Dumps represent cheap land often already owned by a cash-strapped town or city, plus serve as rare high ground in a flood-prone state. And this is just the beginning of Louisiana’s nightmare.

The risk of cancer in Reserve, a community founded by freed slaves, is 800 times the national average, making the community, by one EPA metric, the most carcinogenic census tract in America—the cause is a DuPont/Denka chemical plant adjacent to the town that annually spews 250,000 pounds of the likely carcinogen chloroprene into the air. If you think the situation in Flint is bad, there are approximately 400 public water systems in Louisiana with lead or other hazardous substances leaching into the drinking water. Meanwhile, hundreds of petrochemical plants peppered across the state’s lush swampy interior freely emit carcinogens, endocrine disruptors, and neurotoxins into the air and water, as well as inject them deep into the earth.

Perhaps it’s no surprise that Louisiana is ranked, according to different surveys, 47th in environmental quality, third in poverty, and 49th in education. Are you still gushing about your latest trip to New Orleans for Jazz Fest Presented by Shell, or French Quarter Festival presented by Chevron? “New Orleans is the best,” one visitor recently wrote to me, “you are so smart to live there!” But how smart is it to allow children to attend school built on toxin-laced waste? How smart is it to allow a community’s cancer rates to shoot off the charts? Louisiana is rich in culture, spirit, and faith, yet what type of state knowingly poisons its own people? What type of country stands by and allows it to happen?
