McMullen County Toxic Exposure and Industrial Injury Attorneys

Every morning for decades, workers across McMullen County headed out to the Eagle Ford Shale, to the drilling pads near Tilden, and along the supply corridors that fuel the South Texas economy. You did the heavy lifting. You hauled the fracking sand, you maintained the high-pressure lines, and you worked in the shadow of massive machinery at sites owned by some of the largest oil and gas corporations in the world. Nobody told you that the dust you inhaled while unloading proppants or the sweet-smelling vapors near the separators were rewriting your DNA.

Now, the shortness of breath isn’t just “getting older.” The persistent cough isn’t just “the South Texas crud.” And the diagnosis the doctor gave you in San Antonio—mesothelioma, acute myeloid leukemia, or silicosis—isn’t just a streak of bad luck. It is a biological betrayal.

We are Attorney 911. Led by Ralph Manginello, a trial veteran with more than 27 years of experience and a track record in massive litigation like the BP Texas City Refinery explosion, and Lupe Peña, a former insurance defense insider who once represented the very corporations you are now fighting against. We understand the unique industrial landscape of McMullen County. We know that in a county with more oil rigs than traffic lights, your life was often treated as a line item on a corporate balance sheet.

If you or a loved one has been diagnosed with a disease linked to toxic exposure or has suffered a catastrophic injury on a McMullen County job site, you are not just a case number. You are a neighbor. And the companies that poisoned you have a team of lawyers. Call 1-888-ATTY-911. It’s time you had the most aggressive team in Texas on your side.

The Science of Betrayal: How McMullen County Workers Were Exposed

In McMullen County, the primary threat hasn’t been a single event, but the cumulative burden of decades of unregulated industrial activity. Whether you were an insulator at a local facility, a roughneck on a drilling floor, or a truck driver hauling materials through Tilden, the substances you encountered were invisible killers.

Asbestos: The Permanent Invader in South Texas Infrastructure

Asbestos fibers are naturally occurring silicate minerals that form microscopic, needle-like shards. Despite industry knowledge dating back to the 1930s, asbestos was used pervasively throughout industrial sites in and around McMullen County. It was in the gaskets of the drilling equipment, the insulation of the transport lines, and the fireproofing in the older buildings.

When asbestos is disturbed—during maintenance, demolition, or routine wear—microscopic fibers measuring less than 5 micrometers are released into the air. When you inhale these, they travel deep into the alveoli of your lungs. Because they are biopersistent, your body cannot break them down. Your immune system sends macrophages to engulf and destroy the foreign particles, but the fibers are too sharp and too long. This leads to what we call “frustrated phagocytosis.”

The dead macrophages release inflammatory cytokines like TNF-α and IL-1β, initiating a cycle of chronic inflammation that lasts for decades. Over 20 to 50 years, this oxidative stress damages the DNA of the mesothelial cells, specifically deactivating tumor suppressor genes like BAP1 and NF2. This is the exact cellular mechanism that leads to mesothelioma. As Ralph Manginello often tells his clients, “The company knew the fibers wouldn’t leave your lungs. They just didn’t think you’d ever find out they knew.”

Benzene: The Molecular Assassin in the Eagle Ford Shale

If you worked near the wellheads or the storage tanks in McMullen County, you were likely exposed to benzene. Benzene is a fundamental component of crude oil and a known human carcinogen. Unlike other toxins, benzene attacks the bone marrow microenvironment.

Once inhaled or absorbed through the skin, benzene is metabolized in your liver by the enzyme CYP2E1 into benzene oxide. This further breaks down into muconaldehyde—a highly toxic compound that binds to the DNA of your hematopoietic stem cells. In the bone marrow of McMullen County oilfield workers, these metabolites cause specific chromosomal translocations, such as t(8;21), which are the hallmark of acute myeloid leukemia (AML).

Crystalline Silica: The Hidden Threat of South Texas Fracking

McMullen County is the heart of the Eagle Ford fracking boom. Fracking requires massive quantities of “frac sand,” which is nearly pure crystalline silica. When workers handle this sand, fine dust (respirable crystalline silica) is released. These particles are 100 times smaller than the sand you find on a beach.

Inhaled silica dust enters the lung tissue and triggers a fibrogenic cascade. The lungs develop small, hard nodules of scar tissue. This is silicosis. As the disease progresses, your lungs lose their elasticity, making every breath a struggle. For workers in the South Texas energy corridor, this is a preventable tragedy caused by companies that refused to implement basic dust suppression technology.

The Attorney 911 Advantage in McMullen County

Why choose us? Because you aren’t just fighting a local employer; you are often taking on multinational energy giants with multi-billion dollar defense budgets.

Ralph Manginello brings nearly three decades of high-stakes litigation experience to the table. His work in the U.S. District Court for the Southern District of Texas has given him a deep understanding of federal safety regulations and corporate accountability. Ralph’s experience in the BP Texas City Refinery explosion litigation, a case that resulted in $2.1 billion in settlements and verdicts, proved that he does not blink when facing the world’s most powerful corporations.

Lupe Peña provides our firm with a “nuclear differentiator.” Before joining us to fight for the people of McMullen County, Lupe spent years working for the very insurance firms that defend these corporations. He knows the playbook. He knows how they attempt to “low-ball” settlements, how they hide evidence of exposure, and how they use delay tactics to wait out terminal patients. As Lupe says, “I used to be the one finding ways to deny these claims. Now, I use that knowledge to make sure they can’t ever hide from the truth again.”

With our firm, you get direct access. Call 1-888-ATTY-911 and you don’t talk to a call center in another country. You talk to a team that understands South Texas, understands the state of our courts, and understands that your family’s future is on the line.

Mesothelioma and Asbestos Claims in McMullen County

Mesothelioma is an aggressive, terminal cancer that affects the lining of the lungs (pleural), abdomen (peritoneal), or heart (pericardial). It has one primary cause: asbestos. In McMullen County, generations of workers have been exposed through:

  • Oil and Gas Operations: Heat-resistant asbestos was used in virtually every rig component before the late 1980s.
  • Pipefitting and Insulation: Workers maintaining the energy infrastructure in the Eagle Ford corridor handled asbestos-lagged pipes daily.
  • Secondary Exposure: Many wives and children in McMullen County were exposed when workers brought home “dusty” clothes. Asbestos fibers transferred to the family car and the laundry room, leading to “take-home” mesothelioma decades later.

Understanding the Asbestos Bankruptcy Trusts

If the company you worked for decades ago is now bankrupt, you may think your chance for compensation is gone. This is a common misconception that corporate lawyers love to encourage. In reality, over 60 active asbestos bankruptcy trusts currently hold approximately $30 billion in assets.

These trusts were established by court order to ensure that future victims—like current residents of McMullen County—receive compensation even if the original manufacturer is no longer in business. We have the expertise to navigate the Trust Distribution Procedures (TDP) for major trusts like the Johns-Manville Trust, the Owens Corning Trust, and the W.R. Grace Trust.

The Manville Trust currently pays about 5.1% of approved claim values, while others, like the Shook & Fletcher Trust, pay up to 58%. We fight to secure payments from MULTIPLE trusts simultaneously, often stacking these claims with lawsuits against solvent defendants. The clock is ticking—as assets are depleted, these payment percentages can drop. Call 1-888-ATTY-911 to lock in your claim today.

Axis 1: Toxic Substance Exposure Depth

While asbestos is our anchor, the Manginello Law Firm handles the full spectrum of toxic torts affecting the McMullen County community.

Benzene and the Oilfield Workforce

Acute Myeloid Leukemia (AML) and Myelodysplastic Syndrome (MDS) are the signature cancers of the South Texas oilfield. If you were a refinery operator, a tank cleaner, or an oilfield technician in McMullen County and now suffer from unexplained fatigue, bruising, or a low white blood cell count, you need a medical evaluation that looks specifically for benzene biomarkers. Our medical experts utilize immunohistochemistry to identify the specific chromosomal damage caused by your workplace exposure.

PFAS: The “Forever Chemical” Threat

Per- and polyfluoroalkyl substances (PFAS) are used in firefighting foams (AFFF) common on industrial sites and airports near McMullen County. These chemicals do not break down in the environment. They migrate into the groundwater, contaminating the very wells the people of Tilden rely on. PFAS exposure is linked to kidney cancer, testicular cancer, and thyroid disease. We are currently investigating community contamination claims where industrial runoff has entered the McMullen County water table.

Roundup and Pesticide Exposure

McMullen County isn’t just about oil; it’s about the land. Ranchers and agricultural workers who have used Roundup (glyphosate) for years are now being diagnosed with Non-Hodgkin Lymphoma. The “Monsanto Papers”—internal documents revealed in recent litigation—showed that the company ghostwrote studies to hide the cancer risk. Juries have responded with multi-billion dollar verdicts. If you worked the South Texas land and got sick, we will hold the chemical manufacturers accountable.

Axis 2: Dangerous Industry Worker Injuries in South Texas

McMullen County workers perform some of the most dangerous jobs in the world. When a company ignores OSHA standards or cuts corners on safety to meet a production deadline, “accidents” happen. We know these weren’t accidents—they were choices.

Industrial Explosions and Refinery Accidents

A pressurized line rupture or a chemical release in an energy facility can be catastrophic. Ralph Manginello’s experience in the BP Texas City litigation taught him that these explosions almost always stem from a failure in Process Safety Management (PSM). Under 29 CFR 1910.119, companies are required to anticipate and prevent these disasters. When they don’t, we make them pay.

Crane Collapses and Heavy Equipment Failure

In the Eagle Ford Shale, massive cranes are used to move drilling rigs and infrastructure. A single assembly error or a decision to operate in high winds can lead to a collapse. One cubic yard of soil weighs 3,000 pounds—when a crane drops its load or an unshored trench collapses in McMullen County, survival is measured in minutes. We investigate shift logs, maintenance records, and anemometer data to prove the negligence that led to your injury.

Electrocution and High-Voltage Injuries

Electrical injuries on South Texas job sites are often fatal or result in permanent disability, including cataracts and neurological damage. If your employer violated lockout/tagout (LOTO) protocols under 29 CFR 1910.147, they are responsible for your medical bills and lost earning capacity.

The Multi-Pathway Compensation Strategy

Most law firms in Texas pick one path: workers’ comp or a lawsuit. Attorney 911 handles the full “stack” of compensation. For a single industrial worker in McMullen County, we may pursue:

  1. A Personal Injury Lawsuit: Against solvent third-party contractors and product manufacturers.
  2. Asbestos Trust Fund Claims: Filing simultaneously with multiple national trusts.
  3. Workers’ Compensation: Ensuring your immediate medical bills are covered while we pursue the larger case.
  4. Wrongful Death/Survival Actions: If you have lost a family member, we fight for the loss of consortium and the pain they suffered before their passing.

Every case is unique, and past results do not guarantee a similar outcome. However, with settlement ranges for mesothelioma reaching $1M-$1.4M and verdicts for benzene exposure exceeding $725M in recent years, the stakes could not be higher.

Evidence Preservation: Why You Must Act Now

In McMullen County, the evidence of your exposure is disappearing. Companies shred industrial hygiene reports. Rigs are moved. Old facilities are demolished, taking the asbestos with them. Co-worker witnesses retire and move away.

Within 14 days of being retained, our team sends formal spoliation and preservation demands to all potential defendants. We subpoena OSHA 300 logs and Material Safety Data Sheets (SDS). We work with industrial hygienists to reconstruct the air you breathed 30 years ago. The corporations are counting on you waiting until it’s too late. Don’t give them that victory. Call 888-ATTY-911 today.

Frequently Asked Questions for McMullen County Residents

I was exposed to asbestos 40 years ago. Is it too late to file a claim?

No. Texas follows the “discovery rule.” The statute of limitations typically does not begin until you are diagnosed and learn that the disease was caused by your exposure. For mesothelioma, which has a latency of up to 50 years, your claim is very likely still active.

My employer says workers’ comp is my only option. Is that true?

Almost never. While you may be limited in suing your direct employer, you can nearly always sue the “third parties” responsible—the company that manufactured the toxic chemicals, the contractor that maintained the faulty equipment, or the owner of the premises where you were exposed. These third-party claims have no damage caps.

How much does it cost to hire Attorney 911?

Zero dollars upfront. We work on a contingency fee basis. We advance all the costs of the litigation—expert witnesses, medical record retrieval, and court filings. If we don’t win money for you, you owe us nothing. We only get paid when you do.

Do I have to go to court in Houston?

While our principal office is in Houston, we handle cases throughout McMullen County and South Texas. Much of the litigation process, including depositions and mediations, can now be handled via Zoom or in Tilden/nearby cities. We come to you.

What if the company I worked for is out of business?

This is exactly why the bankruptcy trusts exist. Many of the major asbestos manufacturers and chemical companies from the mid-20th century established these trusts to pay future claims. We can identify which trusts are obligated to pay you.

Your Fight for Justice Starts with One Call

The corporations that operated in McMullen County made billions while their workers paid with their health. They had the studies. They had the warnings. They had the documents—like the Sumner Simpson letters—that proved they knew the danger as early as 1935. They chose their profits. Now, it’s time for you to choose your future.

Whether you are in Tilden, Calliham, or anywhere in South Texas, the legal team at Attorney 911 is ready to stand with you. We have the scientific expertise, the regulatory knowledge, and the trial experience to take on the energy giants and win.

Ralph Manginello and Lupe Peña are waiting to hear your story. Hablamos Español. Your immigration status does not affect your right to justice in a Texas courtroom.

Don’t wait for the trust funds to deplete further. Don’t wait for more evidence to disappear. Don’t wait for your health to decline.
