The Gas That Killed on Screen Is in Your Air Right Now
If you live in the Permian Basin or the Eagle Ford Shale, you may have watched the hydrogen sulfide scene in Landman and felt something cold settle into your chest — not because the show was frightening, but because your body already knows that smell. The rotten-egg odor that comes and goes with the wind. The headaches that hit the whole household on the same afternoon. The child whose asthma started the year the new well went in a quarter mile from the school. You may have told yourself it was allergies, the weather, the dust. A 2024 investigation by journalists and public-health researchers found that roughly 78,000 people lived within a half-mile of Texas wells containing hydrogen sulfide at concentrations classified as “immediately dangerous to life and health” — and at least 33,600 students attended schools inside that same footprint. Those numbers are not from a television script. They are from documented well data, mapping, and census records, and they describe a threat that is still in the air around homes, playgrounds, and classrooms across two of the busiest oil and gas plays in the world.
We are Attorney911 — The Manginello Law Firm, PLLC. We handle toxic tort and environmental exposure cases in Texas, and we built this page for the family sitting at the kitchen table at 2 a.m. with a folder of doctor visits and a suspicion that nobody in authority has been straight with them about what is in the air. What follows is everything we know about how hydrogen sulfide harms the body, who is legally responsible, what the evidence looks like, how fast it disappears, what a case is worth, and what to do in the first 72 hours. None of it is filler. Every section exists because a person in your exact position needs it to make the next decision.
What the Investigation Found: 78,000 People and 33,600 Students
A 2024 joint investigation by journalists and researchers identified specific oil and gas wells in the Permian Basin of West Texas and the Eagle Ford Shale of South Texas that contain hydrogen sulfide at concentrations the government classifies as “immediately dangerous to life and health” — a term reserved for atmospheres that can cause death or permanent harm within minutes. The investigation cross-referenced well data with census and school-enrollment records and produced findings that should change how every parent in the patch thinks about the air outside:
Roughly 78,000 people lived within a half-mile of those wells. At least 33,600 students attended schools in that footprint.
A half-mile is not an abstract distance. It is the length of eight or nine city blocks. It is closer than the nearest grocery store for many families in rural West Texas and South Texas. It is the distance between a front porch and a wellhead that, on a day when the wind shifts, can put a lethal gas into the air a child breathes at recess.
The investigation also documented what residents near leaking facilities have been reporting for years: nausea, headaches, coughing, rashes, and asthma. These are not random complaints. They are the textbook symptom profile of chronic, low-level hydrogen sulfide exposure — the same gas that, at higher concentrations, kills oilfield workers in minutes. The difference between the worker who collapses at the wellhead and the child who develops asthma three blocks away is not the gas. It is the dose. And the dose depends on how much is leaking, how close you are, and how long you have been breathing it.
What Hydrogen Sulfide Does to the Human Body
Hydrogen sulfide — H₂S — is a colorless gas produced naturally in oil and gas formations, including the Permian Basin and the Eagle Ford Shale. It is heavier than air, which means it pools in low-lying areas, valleys, and the ground-level air around homes and schools. The National Institute for Occupational Safety and Health classifies H₂S as immediately dangerous to life and health at 50 parts per million. At higher concentrations, exposure can cause death within minutes by shutting down the body’s ability to breathe at the cellular level.
Here is what happens inside the body — and why the damage is not always obvious at first.
The Mechanism: Cellular Asphyxiation
H₂S works the same way cyanide does. It inhibits cytochrome c oxidase — the final enzyme in the mitochondrial electron transport chain, the machinery every cell uses to turn oxygen into energy. When that enzyme is blocked, the cell cannot use oxygen even when oxygen is present in the blood. The cell suffocates from the inside. The most oxygen-dependent organ — the brain — is the first to fail.
This is why a worker exposed to a high concentration of H₂S can drop without warning: the brain simply stops receiving energy, and consciousness is lost in seconds. At lower concentrations, the same mechanism operates more slowly — a chronic deprivation that erodes neurological function, respiratory health, and the body’s ability to repair itself, day after day, year after year.
The Rotten-Egg Trap: Olfactory Fatigue
H₂S has a distinctive rotten-egg odor at low concentrations — and that odor is the body’s only natural warning system. But the gas defeats that warning system in two stages. First, olfactory fatigue sets in: after even a few minutes of exposure, the nose stops detecting the smell. The odor seems to disappear, even though the gas is still present. Second, at higher concentrations, olfactory paralysis occurs: the nerve that transmits smell is itself disabled. A person in a dangerous atmosphere may smell nothing at all — and conclude they are safe.
This is the cruelest feature of H₂S toxicity. The body’s alarm goes silent at exactly the moment the danger is greatest. Residents who say “I don’t smell anything anymore” may be describing the most dangerous phase of exposure, not the absence of it.
Acute vs. Chronic: Two Different Diseases From the Same Gas
Acute exposure — a high-concentration release, a wellhead blowout, a tank venting, a pipeline leak — produces rapid, dramatic harm: loss of consciousness (the oilfield term is “knockdown”), respiratory failure, cardiac arrest, and death. Survivors of acute knockdown can suffer permanent brain injury from the period of oxygen deprivation, including memory loss, cognitive deficits, and motor impairment.
Chronic, low-level exposure — the daily, ambient drift from a well that leaks small amounts of H₂S into the surrounding community — produces a different set of harms that build slowly and are harder to connect to the source. The medical literature and the residents’ reports align:
- Neurological: chronic headaches, memory problems, difficulty concentrating, balance disturbances, chronic fatigue. Studies have connected long-term, low-level H₂S exposure to broader neurological deficits.
- Respiratory: persistent cough, asthma onset or worsening, bronchial hyperreactivity, decreased pulmonary function. Children are especially vulnerable because their respiratory systems are still developing and they breathe more air per pound of body weight than adults.
- Dermatological: rashes and skin irritation, particularly with direct contact or prolonged ambient exposure.
- Gastrointestinal: nausea, which residents near leaking facilities report frequently.
The proof problem with chronic exposure is that each symptom, taken alone, looks ordinary. A headache is a headache. A cough is a cough. The defense will argue these are allergies, dust, pollen, pre-existing conditions, or stress. The answer is the pattern — the same symptoms appearing in the same households, in the same neighborhoods, at the same distances from the same wells, at rates that exceed what you would expect in an unexposed population. That pattern is built by an epidemiologist who models the exposure plume and compares it to the health records of the people who live inside it.
Why Children Are Different
The 33,600 students in the investigation’s footprint are not just smaller adults. Children breathe faster — their minute ventilation per unit of body weight is higher, which means they inhale more of whatever is in the air for their size. Their blood-brain barriers are not fully developed, making neurotoxins more dangerous. Their lungs are still growing, and airway irritation during development can produce permanent changes in lung function. And they cannot report symptoms the way an adult can — a six-year-old does not say “I am experiencing olfactory fatigue.” A six-year-old says nothing, or says her head hurts, and the parent writes it off as a long day.
This is why the pediatric population near high-H₂S wells is the most legally significant group in the investigation. If chronic exposure can be tied to measurable health effects in children, the damages include not just past medical bills but a lifetime of potential neurological and respiratory consequences — and the cost of medical monitoring for every child who was exposed but has not yet developed symptoms.
Where the Danger Lives: The Permian Basin and the Eagle Ford Shale
Texas oil and gas is not one place. It is two distinct producing regions, each with its own geology, its own H₂S profile, its own communities, and its own courthouse. Understanding where you live in relation to these plays is the first step in understanding your exposure.
The Permian Basin: West Texas
The Permian Basin spans West Texas and southeastern New Mexico, but the heart of American oil production beats through the Midland-Odessa corridor along Interstate 20. This is the most productive oil basin in the United States, and it has been producing for nearly a century — which means the well inventory includes both cutting-edge modern wells and aging, legacy infrastructure that has been in the ground for decades. H₂S concentrations in Permian formations can be extreme. Communities like Midland, Odessa, and the smaller towns that dot the surrounding counties — Gardendale, Notrees, Crane, Monahans, Kermit, Pecos — live with active wells, compressor stations, tank batteries, and processing facilities in close proximity to homes, schools, and businesses.
The Railroad Commission of Texas is the primary state regulatory body overseeing oil and gas operations here. The RRC maintains H₂S safety rules that require operators to file contingency plans, conduct monitoring, and follow wellsite safety procedures at wells containing dangerous H₂S concentrations. But the RRC’s rules are written for worker safety at the wellsite — they do not establish ambient air quality standards for the communities around the wells. That is supposed to be the Texas Commission on Environmental Quality’s job, under the Texas Clean Air Act. The gap between what the RRC regulates (the well) and what TCEQ regulates (the air around the well) is the same gap where community exposure lives.
If you are in the Permian Basin, your oilfield exposure is not just a workplace issue. It is a community issue. The wells near your child’s school do not stop emitting when the school bell rings.
The Eagle Ford Shale: South Texas
The Eagle Ford Shale runs from the Mexican border northeast toward the San Antonio metropolitan area, cutting through counties like Karnes, DeWitt, Gonzales, La Salle, McMullen, and Live Oak. The play developed rapidly beginning around 2009, transforming rural ranchland into one of the most densely drilled regions in the country. Eagle Ford wells can carry high H₂S concentrations, and the rapid development means wells, compressor stations, and gathering lines were often placed near existing homes, schools, and community infrastructure with less setback distance than common sense would suggest.
The Eagle Ford presents a different community profile than the Permian. The towns are smaller, more rural, and in some cases heavily Spanish-speaking. The families living near Eagle Ford wells may be multigenerational ranch families, or they may be workers who moved to the area for the boom and stayed. Either way, the exposure is the same, and the legal rights are the same — but the language barrier can be one more wall between a sick family and the legal system. We serve families fully in Spanish. Lupe Peña conducts complete consultations in Spanish without an interpreter, because we understand that a family’s ability to understand their rights should never depend on whether the lawyer speaks their language.
The Regulatory Map: Who Is Supposed to Protect You
Three layers of government have jurisdiction over H₂S from oil and gas operations in Texas:
The Railroad Commission of Texas (RRC) — the primary oil and gas regulator. The RRC’s H₂S safety rules govern wellsite operations, contingency planning, and monitoring at wells that contain dangerous H₂S levels. The RRC’s focus is on the well and the worker — not the family living a quarter mile away.
The Texas Commission on Environmental Quality (TCEQ) — the air quality regulator. TCEQ enforces the Texas Clean Air Act and regulates emissions from oil and gas facilities. TCEQ maintains air quality monitoring stations and a citizen complaint database. If you have called TCEQ to report an odor or symptoms, that complaint is a public record — and it is evidence.
The U.S. Environmental Protection Agency (EPA) — under the federal Clean Air Act, the EPA regulates hazardous air pollutants from oil and gas operations. The EPA’s Risk Management Program, under 40 CFR Part 68, requires facilities that hold more than 10,000 pounds of hydrogen sulfide in a process to file a formal accident-prevention plan — including a worst-case release scenario that models how far a toxic cloud would travel into the surrounding community. If a facility near your home crossed that threshold, the company was required to map the blast zone on paper, years before anyone was hurt.
The gap between these three regulators is the space where community exposure thrives. The RRC watches the wellhead. TCEQ watches the monitoring station (if there is one nearby). The EPA watches the filing cabinet. Nobody is watching the air between the well and the school. That is the gap a toxic tort case forces closed.
Who Is Responsible: The Defendant Stack
A toxic exposure case is never about one company. It is about a stack of entities, each of which played a role in allowing H₂S to reach the air your family breathes. Naming the right defendants — and piercing the corporate structures that separate them — is the difference between a case that produces accountability and one that produces a shrug.
The Well Operator
The company that operates the well — the entity listed on the RRC permit — owes the primary duty to safely operate a facility containing gas at concentrations classified as immediately dangerous to life and health. This duty is not limited to the workers on the site. Texas courts have recognized theories of strict liability for abnormally dangerous activities, and oilfield operations that release toxic gas into surrounding communities may qualify. The operator knew, or should have known, what concentrations of H₂S were in their wells. The operator chose where to place the well, how to maintain the wellhead, what monitoring to conduct, and what to do when the monitoring showed a problem. The gap between what the operator knew and what the operator did is where liability lives — and where punitive damages become possible.
The Parent or Holding Company
The name on the well permit is frequently a small operating LLC — a thinly capitalized entity designed to hold the liability while the parent company holds the assets. This is the same corporate structure strategy used in industries from trucking to nursing homes: build a wall between the entity that causes the harm and the entity that profits from the operation. Texas law allows plaintiffs to pierce that wall through alter-ego and enterprise-liability theories where the parent exercised operational control or directed safety practices at the well sites. If the parent set the budget, approved the safety plan, or dictated the monitoring protocol, the parent is a defendant.
Well Service and Maintenance Contractors
The company that maintained the wellhead, inspected the valves, or serviced the containment systems owes a duty to perform that work correctly. A corroded valve, a failed seal, a cracked wellhead component — any of these can be the mechanical failure that let H₂S escape. The maintenance contractor’s records show whether the equipment was inspected on schedule, whether defects were documented, and whether repairs were made or deferred. Negligent maintenance is a separate theory of liability, and the contractor is a separate defendant with its own insurance.
Pipeline and Midstream Companies
If the H₂S-rich gas (known in the industry as “sour gas”) is being transported, processed, or handled by a midstream company — a pipeline operator, a gas processing plant, a compressor station — that company contributes to ambient H₂S levels through its own leaks, venting, and emissions. The midstream company is a separate entity from the well operator, with its own duty to handle sour gas safely, and its own exposure to community claims.
Property Owners and Lessees
The entity that owns or leases the land where the well sits — and that allowed the well to be placed in proximity to homes, schools, and community infrastructure — may face premises-liability claims for allowing a dangerous condition to persist on land used near inhabited areas.
The Evidence Clock: Records That Disappear
Toxic exposure cases are won or lost on evidence that has an expiration date. The records that prove what was in the air, what the company knew about it, and what the company did (or did not) do about it are not permanent. They are subject to retention schedules, overwrite cycles, and the quiet disappearance that happens when nobody demands them in time. The preservation letter — a formal demand to freeze all relevant evidence — is the first document we send, and it goes out the day you call, not the day a lawsuit is filed. Here is what that letter targets, system by system.
H₂S Monitoring and Wellhead Data
The operator’s own monitoring data — continuous H₂S readings, wellhead pressure records, leak-detection system logs — establishes the magnitude and duration of H₂S levels at specific wells. This data proves the hazard existed at concentrations classified as immediately dangerous to life and health and provides the dose estimates for nearby populations.
Who holds it: The well operator, and sometimes a third-party monitoring contractor.
How fast it can die: Operators may revise, overwrite, or report that historical monitoring data has been “lost” or was never retained. Digital monitoring systems can overwrite on rolling cycles. There is no universal federal retention mandate for community-level H₂S monitoring data — the company’s own retention policy governs, and those policies are designed to protect the company, not you. The preservation letter is the only thing that converts a routine data-purge into spoliation — the legal term for destroying evidence after being told to preserve it, which allows a jury to assume the destroyed data was as bad as you say it was.
Railroad Commission of Texas Well Files
The RRC maintains public records on every well in Texas: permits, inspection reports, H₂S contingency plans, and any enforcement actions. These records show what the operator told the regulator about the H₂S concentrations at its wells and what safety measures were required.
Who holds it: The Railroad Commission of Texas — these are public records.
How fast they can die: RRC records are generally durable, but they are voluminous and the specific file you need may be archived or difficult to locate without a targeted records request. Regulatory enforcement files may have their own retention limitations. File the records request promptly.
TCEQ Air Quality Data and Citizen Complaint Records
TCEQ maintains air quality monitoring data from its network of stations and a database of citizen complaints. If you or your neighbors have called TCEQ to report odors, symptoms, or concerns, those complaints are public records — and they establish a timeline of community exposure that is independent of the operator’s own data.
Who holds it: TCEQ.
How fast it can die: TCEQ complaint databases and monitoring station data should be requested before any data archiving or purging cycles remove historical records. The complaint you filed two years ago is evidence — but only if it still exists when someone asks for it.
Well Maintenance Records, Valve and Wellhead Inspection Logs
These records show whether the operator maintained its equipment to prevent H₂S migration and whether it had actual or constructive notice of leaking or failing containment systems. A gap in the inspection record — a period where nobody checked the valve that failed — is itself evidence.
Who holds it: The well operator and/or its maintenance contractors, often on-site or at regional offices.
How fast it can die: Maintenance logs are routinely discarded under routine document-retention policies. The spoliation letter must name these records specifically and go out immediately.
Employee and Contractor Testimony
Front-line oilfield workers — the people who staff the wells, run the compressors, and maintain the equipment — often have firsthand knowledge of H₂S releases, inadequate safety protocols, or management’s awareness of community exposure risks. This testimony is critical for punitive damages, because it can establish that the operator knew about the danger and chose not to act.
How fast it can die: Oilfield workers are highly transient. Employee turnover in the Permian Basin and Eagle Ford means witnesses relocate, change employers, or become unavailable rapidly. Identifying and preserving witness testimony is a race against the industry’s own workforce churn.
Ambient Air Sampling
The scientific bridge between well-site H₂S concentrations and community exposure levels is built by independent air sampling — testing the air at the homes, schools, and properties where people are being exposed. Ambient conditions change. Wind shifts. Operators may remediate or repair leaks. The H₂S level that was dangerous last month may be lower today — not because the problem was solved, but because the conditions that caused the reading have temporarily changed.
How fast it can die: The air itself is the evidence, and it is gone the moment the wind shifts. Independent air sampling at the identified locations should be conducted as soon as feasible to capture current H₂S levels before any operator remediation alters the conditions. This is not a records-preservation step — it is a physical evidence-gathering step, and it has its own clock.
What Your Case May Be Worth
Every toxic exposure case is different, and the value of yours depends on the severity of proven injuries, the strength of the causation evidence linking specific wells to your exposure, the number of defendants identified, and the venue where the case is filed. What follows is an honest framework — not a promise. Past results depend on the facts of each case and do not guarantee future outcomes.
Individual Claims: The Range
Mild to moderate exposure with transient symptoms — headaches, nausea, respiratory irritation that resolve after the exposure source is removed or the family relocates: approximately $75,000 to $250,000 per individual claimant. These cases are real and compensable, but the defense will argue the symptoms are nonspecific and the causation is speculative. The value is driven by the strength of the exposure modeling and the medical documentation.
Severe chronic exposure causing permanent harm — sustained respiratory disease, permanent neurological damage, or wrongful death from acute H₂S poisoning: $2,000,000 to $15,000,000 or more per claimant. These cases require robust expert testimony on dose-response relationships, a life-care plan for future medical needs, and a forensic economist to reduce future costs to present value. The neurological damage from chronic H₂S exposure may not be visible on a standard CT scan — just as a traumatic brain injury can exist with a clean scan, the cognitive and memory deficits from H₂S require neuropsychological testing and expert testimony to prove.
The Mass Tort Dimension
When 78,000 people live within a half-mile of identified high-H₂S wells and 33,600 students attend schools in that footprint, the aggregate exposure population is large enough to support coordinated mass tort litigation. The aggregate value of a mass tort across the Permian Basin and Eagle Ford Shale could range from $50,000,000 to $500,000,000 or more, depending on the number of qualifying plaintiffs, the severity of proven injuries, the number of operator defendants, and the strength of the causation evidence.
The presence of 33,600 students in the exposure footprint significantly elevates the mass tort potential — not just because of the vulnerability of the pediatric population, but because of the availability of medical monitoring as a remedy. Medical monitoring is the cost of future medical surveillance for exposed but currently asymptomatic people — the periodic testing, screening, and evaluation needed to catch disease early in a population that has been put at elevated risk. For children exposed to H₂S during their developmental years, medical monitoring could mean years of pulmonary function testing, neurological screening, and respiratory health surveillance — and the operator who caused the exposure should pay for every year of it.
Texas Damage Categories
Texas toxic tort claims seek two categories of compensatory damages:
Economic damages — past and future medical expenses (respiratory treatment, neurological evaluation, diagnostic testing, medication, ongoing monitoring), lost wages, and diminished earning capacity where neurological effects impair cognitive or physical function. These are objective, calculable, and uncapped.
Non-economic damages — pain and suffering, emotional distress, loss of quality of life, and the anxiety of living with continued exposure risk. These are the human costs no receipt can measure.
Exemplary (punitive) damages — Texas allows exemplary damages where the defendant acted with malice or gross negligence — actual awareness of the danger and conscious disregard for the safety of others. The investigation’s identification of wells with IDLH-level H₂S near populated areas provides a foundation for arguing conscious disregard: the operator knew the well contained lethal gas, knew people lived nearby, and failed to implement known, available safety measures. Texas caps exemplary damages — generally at the greater of $200,000 or two times the economic damages, plus up to $750,000 in non-economic damages — but the cap does not apply to the economic and non-economic foundation beneath it. The economic stream is uncapped.
Texas Law: The Rules That Govern Your Case
The Statute of Limitations: Two Years, With a Critical Exception
Texas imposes a general two-year statute of limitations on personal injury and wrongful death claims, governed by the Texas Civil Practice and Remedies Code. For most injuries, the clock starts on the date of the injury. But toxic exposure is different. The disease caused by chronic H₂S exposure may not appear for months or years after the exposure began — and the connection between the gas and the harm may not be apparent until a doctor, an investigator, or a lawyer identifies it.
Texas applies the discovery rule to latent injury claims: the clock may not start until the plaintiff knew, or by reasonable diligence should have known, both that they were injured and that the injury was caused by the exposure. For a family that has been breathing low-level H₂S for years and only recently learned that the well near their home contains gas at immediately-dangerous concentrations, the discovery rule may mean the clock started recently — not years ago.
But the discovery rule is not automatic. It is litigated. The defense will argue that you “should have known” earlier — that the odor, the symptoms, or the well’s presence should have put you on notice. The application of the discovery rule to chronic toxic exposure is a legal question that must be confirmed with counsel for your specific situation, and the safest assumption is that the deadline is real and running. Do not wait to find out.
Comparative Fault: The 51% Bar
Texas follows a modified comparative negligence standard with a 51% bar. Your recovery is reduced by your percentage of fault — and if you are found 51% or more at fault, you recover nothing. In a toxic exposure case, the defense may try to assign you fault for choosing to live near the well, for not moving sooner, for smoking, for pre-existing conditions, or for failing to report symptoms. Every percentage point they pin on you is money off your recovery. The defense works hard on this because every point is cheaper than admitting the well caused the harm.
The Stowers Demand: A Texas Advantage
Texas has a unique insurance doctrine — the Stowers demand — that creates pressure on defendants and their insurers to settle. When a plaintiff offers to settle within the policy limits and the insurer refuses, the insurer may become personally liable for any excess verdict — even if the verdict exceeds the policy by millions. A properly structured Stowers demand, sent early in the litigation, can force an insurer to take a case seriously that it would otherwise string along with delay tactics. Lupe Peña spent years inside a national insurance-defense firm — he knows how insurers evaluate Stowers exposure from the inside, because he used to be the person on the other side of the table making that calculation.
The Insurance Playbook: What to Expect
When a family files a toxic exposure claim against an oil and gas operator, the response is not a surprise. It is a playbook — a series of moves designed to minimize the payout, extend the timeline, and exhaust the claimant. Here are the plays you should expect, and the counter to each.
Play 1: “These Levels Are Safe”
The operator’s first move is to argue that the H₂S concentrations near your home are within acceptable limits — too low to cause the symptoms you are reporting. They will produce their own monitoring data showing low readings, and they will hire an expert to testify that chronic low-level H₂S exposure does not cause the health problems you are describing.
The counter: The operator’s monitoring data is only as good as where they placed the monitors. A monitor at the wellhead does not measure the air at your child’s school. Independent air sampling at the point of exposure — your home, your property, your child’s classroom — is the answer to a wellhead reading. And the medical literature on chronic low-level H₂S exposure is growing: the symptoms residents report (nausea, headaches, coughing, rashes, asthma, neurological effects) are documented in the scientific literature as effects of exactly the kind of exposure the investigation identified.
Play 2: “Something Else Caused Your Symptoms”
The defense will argue that your headaches are from stress, your cough is from dust, your child’s asthma is genetic, and your rash is an allergy. Each symptom, taken alone, has an alternative explanation that does not involve the well.
The counter: The pattern defeats the alternative-cause argument. When the same symptoms appear in the same households at the same distances from the same wells at rates that exceed what you would expect in an unexposed population, the alternative-cause defense collapses. An epidemiologist models the exposure plume and compares it to the health records of the people inside it. A toxicologist establishes the dose-response relationship. A differential diagnosis by a treating physician rules out the alternative causes the defense wants to blame. The answer to “something else caused it” is “prove it — because the pattern says otherwise.”
Play 3: The Quick Nuisance-Value Offer
Some families receive a fast offer — a check for a modest amount, accompanied by a release that would extinguish all future claims, including claims for medical conditions that have not yet appeared. The offer may arrive before you have finished documenting your symptoms, before you have seen the right specialists, and before anyone has tested the air at your home.
The counter: A release signed today covers the disease that develops five years from now. The quick check is designed to buy the silence of the family that does not yet know the full extent of the harm. Do not sign anything, do not accept any payment, and do not provide a recorded statement to anyone representing the operator or its insurer before you have spoken with a lawyer. The preservation of your future rights is worth more than any check that arrives before the medical evaluation is complete.
Play 4: The Delay Toward the Statute of Limitations
The insurer may string the claim along — requesting more documentation, conducting lengthy “investigations,” making partial admissions followed by retreats — all aimed at running the two-year statute of limitations until your claim is time-barred and you have no case at all.
The counter: The preservation letter, the medical evaluation, and the filing of the lawsuit are all on a schedule that we control, not the insurer. The day you call is the day the clock starts working for you instead of against you. We do not wait for the insurer to finish its “investigation” before we act — because the insurer’s investigation is not designed to find the truth. It is designed to run out the clock.
How We Build the Proof
Here is how a toxic exposure case like this is actually built — not in theory, but in the order the work gets done.
Week one: The preservation letter goes out — to the well operator, to the maintenance contractor, to the midstream company, and to any monitoring vendor. The letter names every category of evidence: H₂S monitoring data, wellhead pressure records, leak-detection logs, maintenance and inspection records, RRC filings, TCEQ complaints, employee rosters, and internal communications about community exposure. The letter converts routine document destruction into spoliation — and puts the company on notice that destroying evidence after this letter will have consequences in front of a jury.
Week two through four: Independent air sampling is arranged at the affected properties, schools, and community locations. The operator’s RRC well files, inspection reports, and H₂S contingency plans are requested. TCEQ air quality monitoring data and citizen complaint records are pulled. The community health profile begins to take shape — who is sick, with what, and where they live in relation to the wells.
Month two through three: Medical records are gathered and organized. Treating physicians are identified. If neuropsychological testing is needed for cognitive deficits, it is scheduled. If pulmonary function testing is needed for respiratory effects, it is completed. The life-care planner begins building the future-cost stream for any permanent injury.
Month three through six: Experts are retained. A board-certified toxicologist establishes general causation — that H₂S at the documented concentrations causes the documented health effects. An epidemiologist models the community exposure — who was exposed, to what dose, over what period. An environmental engineer analyzes the well-site containment and identifies the specific failure that allowed H₂S to reach the community. If children are involved, a pediatric neurologist evaluates the developmental risks.
Month six and beyond: Discovery — the formal process of demanding documents and testimony from the defendants — begins. The operator’s internal communications about H₂S concentrations, community complaints, and safety decisions are produced. Depositions are taken — the safety director, the site manager, the maintenance contractor, the monitoring vendor. Under oath, the people who ran the operation explain the choices they made. The gap between what they knew and what they did is where the case is won.
The number at the end — the settlement or verdict — is built from all of it. Every document, every test, every deposition, every expert report. It is not a guess. It is an architecture, and it is built piece by piece from the day you call.
Your First 72 Hours: A Roadmap
If you or your family are experiencing symptoms you believe may be connected to H₂S exposure from nearby oil and gas operations, here is what to do — and what not to do — in the first 72 hours.
Do: Seek Medical Evaluation
See a physician and describe your symptoms, your proximity to oil and gas operations, and your concern about H₂S exposure. Be specific about the symptoms — headaches, nausea, coughing, rashes, asthma, memory problems, dizziness — and about when they started in relation to when the well began operating or when you first noticed odors. Request that your symptoms and your exposure concern be documented in your medical record. If your child is symptomatic, have the child evaluated by a pediatrician. If respiratory symptoms are severe, go to the emergency room. Your health comes first, and the medical record created now is evidence that will matter later.
Do: Document Everything
Start a symptom journal. Write down what you feel, when, and what the conditions were outside — wind direction, odor, visible operations at the well site. Photograph the well site from your property. Photograph any visible emissions, vapor, or equipment conditions. Save every communication you have had with the operator, the RRC, TCEQ, or anyone else about the well or the odors. If you have called TCEQ to complain, request a copy of your complaint record. If neighbors have similar symptoms, talk to them — the pattern is the proof, and the pattern is built household by household.
Do Not: Sign Anything
Do not sign a release, a waiver, a settlement agreement, or any document presented by the operator, the operator’s insurer, or anyone representing the operator’s interests. Do not accept a check. Do not agree to allow the operator or its contractor to conduct testing on your property without speaking to a lawyer first. A document signed in the first 72 hours can extinguish rights you do not yet know you have.
Do Not: Give a Recorded Statement
The operator’s insurer may call — friendly, concerned, asking you to “just tell us what happened” on a recording. This is not a courtesy. It is a recorded statement designed to be quoted against you later. Decline politely. Do not speculate about causes, do not minimize your symptoms, and do not say “I’m feeling okay” if you are not. The safest answer is: “I need to speak with a lawyer before I make any statement.”
Do Not: Post on Social Media
Do not post about your symptoms, your concerns, or the well on social media. The defense will mine your social media for anything that can be used to minimize your claim — a photo of you at a family barbecue used to argue “she looks fine,” a post about a bad day used to argue “he was already stressed.” Assume everything you post will be read by a lawyer whose job is to pay you as little as possible.
Do: Call Us
The consultation is free. The call is 1-888-ATTY-911. We are available 24 hours a day, 7 days a week — not an answering service, but live staff who can start the process immediately. The preservation letter can go out the same day you call. The clock on the evidence starts working for you the moment you pick up the phone.
Frequently Asked Questions
How do I know if the well near my home has high H₂S levels?
The Railroad Commission of Texas maintains public records on oil and gas wells, including H₂S concentration data and contingency plans for wells that contain dangerous levels. You can search the RRC’s online database by county, operator, or well location. If a 2024 investigation identified your area as being within a half-mile of high-H₂S wells, the well data is already on record. But the RRC database is not user-friendly, and the specific H₂S concentrations may be buried in permit filings and contingency plans. We can help you pull and interpret the records for your specific location.
Can I sue if I don’t have a specific disease diagnosis yet?
If you have been exposed to H₂S at documented dangerous concentrations and are experiencing symptoms — headaches, nausea, coughing, rashes, asthma — you have an injury claim even if no doctor has given you a specific disease name. The symptoms are the injury, and the medical documentation of those symptoms is the proof. For asymptomatic individuals who were exposed but have not developed symptoms, the claim may be for medical monitoring — the cost of future surveillance to catch disease early. Medical monitoring is a recognized remedy in mass toxic tort cases, particularly for children whose developing systems may show effects years after the exposure.
How long do I have to file a lawsuit in Texas?
Texas generally imposes a two-year statute of limitations on personal injury and wrongful death claims. For toxic exposure, the discovery rule may extend the clock — it may not start until you knew or should have known that your injury was caused by H₂S exposure. But the discovery rule is not automatic and is litigated case by case. Do not assume you have plenty of time. The safest move is to speak with counsel now — the consultation is free, and the cost of waiting may be the case itself.
What if I was partly at fault for living near the well?
Texas follows a modified comparative negligence rule with a 51% bar. Your recovery is reduced by your share of fault, but it is not eliminated unless you are 51% or more at fault. Choosing to live near a well is not negligence — you have the right to live in your home without being poisoned by your neighbor’s industrial operation. The defense may try to assign you fault, but a skilled attorney fights every percentage point because every point is money off your recovery.
Can my child’s school be held responsible?
The school district is generally not the primary defendant in an H₂S exposure case — the well operator is. But if the school was built or operated with knowledge of the nearby H₂S hazard, and if the school failed to take reasonable steps to protect students (monitoring, ventilation, notification, evacuation protocols), the school district may face claims as well. The primary focus, however, is on the operator that created the hazard and the entities that allowed it to persist near populated areas.
What is medical monitoring and how much is it worth?
Medical monitoring is a damages category that covers the cost of future medical surveillance for people who have been exposed to a toxic substance but have not yet developed a diagnosable disease. For children exposed to H₂S, this may include years of pulmonary function testing, neurological screening, and respiratory health evaluation. The cost depends on the number of exposed individuals, the duration of monitoring needed, and the specific tests recommended by medical experts. In a mass tort involving 33,600 students, medical monitoring alone could represent a significant component of the total recovery. The operator who caused the exposure should pay for the surveillance — not the families, not the schools, not the taxpayers.
Is this a class action or do I keep my own case?
Toxic exposure cases can proceed as coordinated mass tort litigation — where cases are grouped for pretrial purposes but each plaintiff retains an individual claim — or as individual lawsuits for severe injury or wrongful death. Coordination allows efficient handling of shared evidence (the well data, the exposure modeling, the expert testimony) while preserving each family’s right to have their specific injuries evaluated and compensated individually. Your case is never absorbed into a single “pot” — you keep your own claim, your own injuries, and your own recovery.
What does it cost to hire a lawyer for an H₂S exposure case?
We work on contingency. That means we do not charge an hourly fee. We are paid a percentage of the recovery — 33.33% before trial and 40% if the case goes to trial — and we do not get paid unless we win your case. The consultation is free. You pay nothing out of pocket to have your case evaluated, your evidence preserved, and your legal options explained. If we are not the right fit for your case, we will tell you — and point you toward someone who is.
Why Our Firm
We are Attorney911 — The Manginello Law Firm, PLLC. We have been handling personal injury, wrongful death, and toxic tort cases in Texas since 2001. We are not a firm that discovered toxic exposure yesterday and wrote a web page about it today. We understand the oilfield because we have spent decades around it.
Ralph Manginello — our Managing Partner — has been licensed in Texas since November 6, 1998. That is 27+ years of trial practice, including in the federal courts of the Southern District of Texas. Ralph was a journalist before he was a lawyer — he trained to find the story the company does not want told, and he brought that instinct into the courtroom. He is admitted to federal court, he has tried cases against corporate defendants, and he leads the active $10 million hazing lawsuit against Pi Kappa Phi and the University of Houston. Ralph does not file a lawsuit to settle it quietly. He files it to win it.
Lupe Peña — our Associate Attorney — is a former insurance-defense attorney who spent years inside a national defense firm. He sat in the rooms where adjusters and their software decided how to deny, delay, and devalue claims exactly like yours. He knows how the reserve is set in the first 48 hours. He knows how the recorded-statement call is engineered. He knows which doctors the insurer sends claimants to for “independent” medical exams that are neither independent nor objective. And now he sits on your side of the table — bringing that insider knowledge to the families the insurance industry used to count on not knowing the playbook. Lupe is a 3rd-generation Texan with family roots to the King Ranch. He conducts full consultations in Spanish without an interpreter — because the families in the Eagle Ford who need legal help should not need a translator to understand their rights.
Our fee is contingency — 33.33% before trial, 40% if we go to trial. We do not get paid unless we win your case. The consultation is free. The call is 24/7. The number is 1-888-ATTY-911.
We handle toxic tort claims, wrongful death cases, brain and neurological injury cases, and workplace and oilfield injury cases across Texas — from our Houston offices to the Permian Basin and the Eagle Ford Shale. We have spent years fighting for workers exposed to toxic substances at refineries and chemical plants — the same chemical-industry accountability fight that community H₂S exposure demands.
