Black, Latinx Californians Face Highest Exposure to Oil and Gas Wells

More than 1 million Californians live near active oil or gas wells, potentially exposing them to drilling-related pollution that can contribute to asthma, preterm births and a variety of other health problems. A new study appearing in the March 23 edition of the journal GeoHealth finds that these Californians are disproportionately Black, Latinx or low-income, and Black Californians are more likely to live near the most intensive oil and gas operations.

More than 1 million Californians live near active oil or gas wells, potentially exposing them to drilling-related pollution that can contribute to asthma, preterm births and a variety of other health problems.

new study appearing in the March 23 edition of the journal GeoHealth finds that these Californians are disproportionately Black, Latinx or low-income, and Black Californians are more likely to live near the most intensive oil and gas operations.

“When we look across the state of California over the past 15 years, Black, Latinx and low-income people consistently were more likely to live near oil and gas wells,” said study first author David González, a President’s Postdoctoral Fellow at the University of California, Berkeley. “Black people, in particular, were more likely to be in places that had the most intensive oil and gas production, which can lead to more exposure to harmful chemicals.”

The study also found that while oil and gas production in California has declined over the past 15 years, the rate of decrease has been slower near racially marginalized communities.

Earlier work led by González found that disparities in exposure to oil and gas wells can be traced back to the 1930s in Los Angeles and linked to the historical policy of redlining.

“What’s emerging is that oil and gas wells have been disproportionately impacting racially marginalized and low-income communities in California for generations,” González said.

“We found that redlining was strongly associated with the disproportionate siting of oil and gas wells in historically racially marginalized communities, and we’re still seeing disproportionate siting and production of oil and gas infrastructure in many of these same neighborhoods today.”

Oil and gas production is a complex process that can release an array of hazardous pollutants: Drilling rigs and other heavy machinery emit diesel exhaust, active wells can release toxic volatile organic compounds, and in some cases, the chemicals that are used to extract oil from underground reservoirs can seep into the water supply, endangering those who rely on groundwater for drinking.

Operating heavy drilling machinery in residential areas can also create other stressors, like light and sound pollution.

Mounting evidence suggests that these pollutants pose a variety of health risks to those who live close to wells — that distance usually is defined as living within 1 kilometer (km), or a little over half a mile.

The California climate measures signed into law last September by Gov. Gavin Newsom contained provisions that would ban new drilling within approximately 1 km of homes, schools, hospitals and parks and provide protections for those living near existing wells.

But in early February, oil companies succeeded in putting the law on hold until voters decide its fate in a November 2024 ballot referendum.

“The weight of scientific evidence clearly demonstrates that people living near oil and gas development have a greater risk of respiratory problems and adverse birth outcomes,” said Seth B.C. Shonkoff, executive director of PSE Healthy Energy and an associate researcher at UC Berkeley’s School of Public Health. “Attempts to undermine or delay California’s landmark setback law contradict the science and increase public health risks, particularly for Black and brown communities.”

Given the complexity of oil and gas operations, many studies only consider proximity to wells when investigating the health risks of oil and gas production. However, this focus on proximity may mask additional disparities in the hazards posed by more intensive production, the researchers said.

The current study, which found that Black Californians are more likely to be exposed to more intensive oil productions, might help explain why some studies have found that the health risks associated with living near wells are higher for racially and socioeconomically marginalized people.

Rachel Morello-Frosch, professor at UC Berkeley’s School of Public Health and in the Department of Environmental Science, Policy and Management and the study’s senior author, said she hopes the paper makes clear the health equity implications of the oil and gas industry in California.

“This study advances scientific understanding about the origins and persistence of racialized inequities in exposure to oil and gas extraction in California, which in turn has significant implications for regulatory interventions that center environmental justice in protecting community health from this well-documented environmental hazard,” Morello-Frosch said.

In addition to the 1 million Californians who live near active or retired wells, nearly 9 million — 20% of the population — live close to wells that have been plugged and abandoned, some as early as the 1800s. While wells that have been plugged in recent years are held to rigorous environmental standards, other studies have found that some of these older wells may still be emitting toxic chemicals that could be harmful to those living nearby.

“The most common exposure to oil and gas infrastructure in California was to plugged and abandoned wells,” González said. “From a public health perspective, it’s not clear how worried we should be about plugged wells. But given how many people live near them, I think it’s important to ask more questions and take care when we retire wells so we don’t create problems down the road.”

Additional study co-authors include Claire M. Morton of Stanford University; Lee Ann L. Hill, Drew R. Michanowicz and Robert J. Rossi of PSE Healthy Energy; and Joan A. Casey of the University of Washington. This study was supported by the California Air Resources Board (#18RD018) and National Institute of Environmental Health Sciences (R00 ES027023)

Diabetes in Black California: Turning the Tide from Crisis to Control

According to the Centers for Disease Control and Prevention (CDC) Behavioral Risk Factor Surveillance System data, nearly 17.9% of Black adults in California have been diagnosed with diabetes — above the national Black adult average of 16.8%, and nearly five points higher than California’s overall adult rate of 12.6% across all races. California ranks 24th out of 39 states with available data for Black adult diabetes rates.

Crystal Lambert knew something was terribly wrong with her three-year-old granddaughter as she sped down the street trying to get her to the hospital.

“I thought she got a hold of some poison,” Lambert recalled.

Doctors found Lambert’s granddaughter had a blood sugar level over 800, diagnosing her with Diabetic Ketoacidosis(DKA), a state in which the body, starved of insulin, begins to shut down.

Lambert said she was born with a pancreas that was not fully functioning — it lacked the specialized cells required to produce insulin.

Her granddaughter survived and is five years old today.  Now, she gives herself insulin shots, asks endless questions about her condition, and runs like the spirited child she is. But the terror of that night transformed Lambert — and ultimately inspired her to launch the We Fight Back Organization, a mobile health and food access initiative serving underserved communities across California. Lambert is the executive director.

The Crisis by the Numbers

According to the Centers for Disease Control and Prevention (CDC) Behavioral Risk Factor Surveillance System data, nearly 17.9% of Black adults in California have been diagnosed with diabetes — above the national Black adult average of 16.8%, and nearly five points higher than California’s overall adult rate of 12.6% across all races. California ranks 24th out of 39 states with available data for Black adult diabetes rates.

Nationally, according to the U.S. Department of Health and Human Services, Black Americans were 24% more likely than the overall U.S. population to have diabetes in 2024. They also died from diabetes 78% more often than the general population in 2022. Black Americans are also more than twice as likely as the overall population to develop kidney failure caused by diabetes.

According to the California Health Care Foundation’s 2024 Health Disparities Almanac, Black Californians have the shortest life expectancy in the state at just 74.6 years — due in part to chronic conditions like diabetes and its devastating complications.

Leon Rock, co-founder of the African American Diabetes Association, believes statistics, though revealing, only tell part of the story.

“There are a whole bunch of Black folks that don’t tell you that they have diabetes — or don’t know,” he said.

And the disease itself, Rock is careful to note, is not what kills. “They die from the complications. That’s heart attack, that’s stroke, that’s amputations of legs, of feet. Going blind. All those complications are inherent in a system that has impacted Black folks with diabetes in California and across America.”

An Information Gap Fuels the Crisis

For Rock, part of the solution is diagnosis. He says the medical and public health systems are failing Black Californians by the absence of information designed for them.

“That is the bottom line. We need good information. Information that is culturally specific,” said Rock.

Telling people to eat healthy or exercise, he added, falls short when culturally specific alternatives are not provided, and when many residents of urban communities do not feel safe exercising in some neighborhoods – or outside at night.

Dr. Khadijah Lang, a family medicine physician and president of the Golden State Medical Association, agrees that the roots of the crisis run deeper than individual behavior — and blaming patients misses the point.

“We are not genetically predisposed to diabetes,” Lang said. “But the system under which we live increases the likelihood that we will develop it.” 

What the Body Needs — What Communities Are Denied

Type 2 diabetes, which accounts for 90 to 95% of all diabetes cases, according to the CDC, develops when the body can no longer use insulin effectively to regulate blood sugar. Left unmanaged, it damages nerves, kidneys, eyes, and the cardiovascular system. The hemoglobin A1C test is a blood draw that reveals how the body has processed sugar over the previous three months — not just at the moment of the test. It is the standard tool for both diagnosis and ongoing monitoring.

That distinction matters, Lang emphasized, because patients cannot manipulate three months of blood sugar history the way they might fast for a day before a single blood draw.

“The pill is not meant to undo or control a sugar level that’s being constantly stressed,” Lang said. “It’s meant to work in conjunction with a low-carbohydrate diet and exercise.” She recommended at minimum 30 minutes of physical activity five days a week — breakable into 10-minute sessions for those who need it.

Lang stressed that education must be delivered in language people recognize and can relate to. The goal is to inform them of the choices that serve their health best, she said.

But for many Black Californians, even those informed choices remain out of reach, Lambert said.

“They need access to healthy foods and medication, too” she said.

California has made some critical policy advances. The state has expanded access to the Continuous Glucose Monitor (CGM), which has transformed diabetes care for state residents. Assembly Bill 365, introduced in 2024, proposed requiring Medi-Cal to cover the costs of CGM and other related medical equipment but it failed in the State Senate. Since then, the California Department of Health Care Services (DHCS) reports that the core Medi-Cal CGM benefit now available to eligible patients was solidified through previous budget actions and pharmacy policy updates.

These measures, while meaningful, have not closed the gap for the communities most at risk, according to advocates.

Control Through Community

Health care advocates conclude that the solution must be communal, culturally grounded, and sustained — not a fad, not a celebrity moment, not a single clinic visit. For example, observed Lang, lifestyle shaped by shared values and collective accountability can move the needle where individual prescriptions have not.

Rock is building infrastructure to match the urgency, establishing local chapters of the African American Diabetes Association across the country, with California next.

“We have to do for self, period,” he said. “Health is wealth. We have to eat to live.”

And Lambert, whose granddaughter unknowingly started all of this for her, keeps showing up.

“Diabetes advocacy is about dignity, education, prevention, and hope,” she said.
