Ok, this is it. In this episode we find out what happened in Santa Ana. Well, at least we’ll find out the evidence that our study produced after careful research over several years.

At the end of the episode you will learn how we went about testing different hypotheses, such as “the lead came from the peeling paint on buildings,” or “maybe it came from vehicles using leaded gasoline.” These are questions that required a creative approach that brought together history and environmental science to understand the soil pollution crisis in Santa Ana. I will not give you specific data points here, but you can find detailed charts, regressions, and so on in our published study linked in the episode’s notes.

You will also notice that I am not the only one moving the story forward today. For this episode I worked with students with an Environmental Justice Organizing Academy and they helped me design the episode and explain the study by asking me questions. We worked hard to make this one fun and informative, so I hope you enjoy it!

Ep 5: History, Science, and Community come together in Santa Ana

Lead poisoning is an epidemic that has been ravaging communities of color across the country (and the world) for a hundred years. The story of how it spread to our own backyards has little to do with the individual responsibility of homeowners and parents. This is a story about capitalism, the politics of science, and the subtle (and overt) workings of environmental racism.

Ep1: A Community against Lead

In 2018, residents of Santa Ana (CA) found out that a large portion of the city’s soil was contaminated with lead. Community activists had partnered with University of California-Irvine and conducted a study of 1,500 soil samples across the city. The results: Half of the soil samples showed concentrations of lead that were toxic for children.

Lead poisoning is an epidemic that has been ravaging communities of color across the country (and the world) for a hundred years. The story of how it spread to our own backyards has little to do with the individual responsibility of homeowners and parents. This is a story about capitalism, the politics of science, and the subtle (and overt) workings of environmental racism.

This audio documentary follows a group of activists and researchers as they try to unearth decades of neglect, discrimination, and toxic practices in Santa Ana, CA. You will be an active participant in solving the mystery behind pollution maps: Was it lead-based paint, car emissions, farming practices, or metal factories? Each episode will interrogate these usual suspects while also narrating the history of lead and lead poisoning in the United States. You will hear about lead in paint and how its deleterious effects connected to the issue of affordable housing and redlining. You will also learn about the emblematic citrus groves in Orange County and how the use of the automobile resulted in widespread lead poisoning among American children.
