Candido Alvarez stopped going to doctors years ago. When his body temperature hit 120 degrees Fahrenheit during a construction job and blood appeared in his urine, signaling potential kidney damage from extreme heat exposure, he refused to seek emergency care. A four-hour hospital visit for Covid-19 had cost him $7,500. The bill, he said, felt worse than any illness.
"I'm going to die not so much from the illness but from thinking about how I'm going to pay the rent," the 47-year-old undocumented immigrant from Honduras said.
Alvarez's predicament captures a deepening crisis in Houston's working-class neighborhoods, where lower-income immigrants face a converging threat: environmental hazards from one of North America's largest petrochemical centers, increasing severe weather driven by climate change, crumbling infrastructure that fails repeatedly after disasters, and now a federal immigration crackdown that is keeping people away from hospitals even in emergencies.
Houston's east side, where many immigrants live, sits in what researchers call "the arrow" because of the shape poverty and pollution data form on city maps. The wealthy west side glitters with luxury stores and green space. The arrow points toward the east, where it abruptly ends downtown. Beyond its margins to the south and east, where blue-collar immigrants cluster, poverty rates spike, childhood asthma rates climb, and toxic waste sites multiply. Median home values plummet. College degree attainment vanishes.
A 21-year life expectancy gap separates Houston's richest from its poorest neighborhoods.
"Almost every indicator you look at, this arrow emerges," said Nadia Valliani, director of community impact at the Greater Houston Community Foundation.
The petrochemical concentration around Houston is staggering. Harris County processes 2.6 million barrels of crude oil daily and hosts more than 400 petrochemical facilities lining a 52-mile shipping channel. Human rights advocates have called it a "racial sacrifice zone." Residents report severe respiratory problems. During Harvey in 2017, refineries and chemical plants burned off fuel and chemicals as floodwaters rose. A facility leaked 461,000 gallons of gasoline near a predominantly Latino neighborhood. Air pollution from 340 tons spilled into the atmosphere as plants malfunctioned.
Harvey dumped up to 60 inches of rain, a one-in-1,000-year flood event that scientists say was made 15 to 38 percent worse by climate change. The hurricane killed 89 people and caused $158.8 billion in estimated damages. More recent storms like the 2021 winter storm, the May 2024 derecho, and Hurricane Beryl have battered the region with blackouts lasting days and flooding that lingers.
"I think we just haven't stopped living in survival mode for a very long time," said Norma Gonzalez, a community advocate at Woori Juntos, an immigrant-serving organization in Houston.
Years after Harvey, homes in immigrant neighborhoods remain flooded-damaged with no upgrades to prevent future inundation. Mold spreads. Families board off rooms they cannot afford to repair. After each new storm, the damage compounds. Experts call this psychological toll "recovery from the recovery," as people of color wrestle with trauma, denied aid, unsafe living conditions, and the grim knowledge that the next disaster is coming.
When Hurricane Beryl hit in 2024, Hilda, an undocumented immigrant and three-decade Houston resident who asked to use only her first name due to deportation fears, ran out of her diabetes medication and got severely ill. She lives between Settegast and Trinity Gardens, a historically Black area where immigrants buy cheaper homes because they cannot secure bank loans or credit without a social security number. The strategy makes sense: own an asset quickly, keep it if deported, rent it out. But it also traps families in flood-prone neighborhoods on the lowest ground.
An academic study published in 2023 found that 40 of 46 soil samples tested in northeast Houston showed chemical levels suggesting cancer risk. Some lead levels exceeded safe thresholds for children.
Healthcare access has collapsed under the weight of disaster and policy. In 2017, a survey found that nearly 25 percent of immigrants on the Texas Gulf Coast lacked a doctor's office to visit when sick, forcing them to the emergency room. Over half had no health insurance. More than 40 percent reported needing more help accessing medical care.
Those barriers have only deepened since January 2025. Research from the KFF organization found that 48 percent of likely undocumented immigrants, 14 percent of lawfully present immigrants, and 8 percent of naturalized citizens across the country have skipped medical care because of immigration-related fears. In Houston, immigration enforcement sweeps have emptied clinic waiting rooms.
"People don't want to come out," said Mariela Soberanis, a manager at the Ibn Sina Foundation's network of community clinics serving Houston's poor. "Unless they really, really, really have to."
The clinics provide low-cost care for the uninsured, including specialists, ultrasound exams, bloodwork, dentistry, and minor procedures. Staff have waded through floodwaters to deliver supplies. But now, as immigration enforcement intensifies, patients vanish.
Melissa Villarreal, who researched Hurricane Harvey's impact on Mexican-origin women, described families trapped in homes with mold and holes in roofs because Federal Emergency Management Agency bureaucracy blocked access to loans and assistance. Without credit history or social security numbers, undocumented immigrants face additional FEMA hurdles. Many never recovered from Harvey before the next disaster struck.
"Because they didn't have the money, they never recovered," Villarreal said. "But then what happens the next time there's a disaster?"
Some local organizations are pushing back. Hilda hopes to plant vegetation in her neighborhood to absorb floodwater and address soil contamination. After Harvey, she watched as investors bought flooded homes cheap from desperate residents. Better to own the property outright than lose it to another inundation, families reasoned.
Yet Houston's official flood reduction plans have historically favored wealthy west Houston over northeast neighborhoods where immigrants concentrate. The disparity persists.
Roughly 30 percent of Houston's 2.4 million residents are foreign-born. Nearly one-third of them lack legal status. The city pulses with Vietnamese, Urdu, Tagalog, Arabic, Spanish, and English. Immigrants run much of Houston's economy and shape its culture. Yet they absorb its worst environmental and economic shocks while being systematically excluded from disaster recovery resources and now targeted by federal enforcement.
Alvarez continues construction work in unventilated spaces without proper safety equipment. He avoids the hospital despite worsening health. The choice feels rational to him, even as it slowly kills him. That's survival mode, Houston-style.
Author James Rodriguez: "Houston's poorest neighborhoods have been absorbing disaster after disaster for years while the city's wealthier enclaves get rebuilt first and protected better, and now a deportation crackdown is the final blow keeping desperate people away from doctors."
