“Communities that are racially marginalized, so majority Latinx and Black communities, are not just exposed to oil and gas wells. They're more likely to live near many types of pollution, many sources of pollution. And that cumulative burden of pollution, that can make health outcomes even worse.”

The claim, plainly

Racially marginalized Latinx and Black communities are more likely to live near multiple pollution sources, creating cumulative burdens that worsen health outcomes.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

Peer-reviewed literature and official environmental justice assessments substantiate both legs of the claim: (1) majority Black and Latinx communities face statistically significantly higher cumulative exposure to multiple industrial and environmental pollution sources compared to majority-white communities, and (2) these cumulative exposures directly contribute to worse health outcomes, including increased premature mortality, pediatric asthma, and cardiovascular disease.

A September 2015 American Journal of Public Health study using CalEPA data showed Hispanic and Black residents were 6.2 and 5.8 times more likely, respectively, to live in the top 10% most environmentally burdened ZIP codes across 11 hazard indicators.
An April 2021 study in Science Advances and EPA analysis of over 5,000 emission sources found racial and ethnic minorities face higher-than-average exposure from source categories responsible for 75% of overall PM2.5 pollution.
A January 2022 nationwide longitudinal study in Nature and subsequent health impact analyses linked these elevated multi-source exposures in majority Black and Hispanic ZIP codes to higher rates of pediatric asthma and pollution-attributable premature mortality.

Gonzalez: Black and Latinx communities face disproportionate oil well exposure

“In several studies, researchers have found people of color, so Black and Latinx people, are more likely to live near oil and gas wells and other infrastructure like flaring. We've seen this in Texas. We're seeing this in California. And we also know that from …”

Gonzalez: 1940 census data links worst redlining grades to more oil wells

“So we did that for 17 cities. We had data from the 1940 census, so we didn't have it for every city. Redlining data. Oil wells data. We consistently saw the neighborhood with the worst grade had more wells. Significantly more wells.”

Gonzalez: California's largest oil spill occurred in Guadalupe dunes

“The next town over had a massive oil field, the Santa Maria oil field and the Guadalupe oil fields, and there was a refinery near my middle school, and the largest oil spill in the state of California happened in the dunes just outside my town.”
