Atrazine Lawsuit 2026 | Non-Hodgkin's Lymphoma Claims

Overview of the Atrazine Lawsuit Investigation

The atrazine lawsuit investigation centers on the growing evidence that chronic exposure to this widely used herbicide may cause cancer, particularly non-Hodgkin’s lymphoma (NHL).

Atrazine use has been widespread in American agriculture for decades, with millions of pounds applied annually across cornfields and other crops.

Despite mounting health concerns, the Environmental Protection Agency (EPA) has continued to permit atrazine’s use, though it acknowledges the chemical’s potential to cause adverse health effects.

Scientific studies have linked atrazine to endocrine disruption, which can interfere with hormone regulation and may contribute to the development of certain cancers.

In addition to cancer concerns, atrazine has also been associated with reproductive effects and developmental issues, especially in communities exposed through drinking water.

However, the current legal focus is specifically on individuals who developed NHL following significant atrazine exposure.

Lawsuits are being evaluated to determine whether Syngenta, the primary manufacturer, failed to adequately warn users about the cancer risks.

Atrazine remains one of the most frequently detected toxic substances in U.S. groundwater and surface water, increasing the risk of long-term exposure in both occupational and environmental settings.

Plaintiffs may include farmers, applicators, and others who had regular contact with the chemical in agricultural or turf management settings.

The investigation aims to hold the manufacturer accountable and to seek compensation for those harmed by atrazine-related cancer diagnoses.

What is Atrazine?

Atrazine is a synthetic herbicide commonly used to control broadleaf and grassy weeds in crops like corn, sorghum, and sugarcane.

Introduced in the late 1950s, it quickly became one of the most widely used agricultural chemicals in the United States. Atrazine works by inhibiting photosynthesis in plants, but its persistence in soil and water has raised environmental and health concerns.

The chemical is known to travel far from application sites, frequently contaminating groundwater, streams, and even drinking water supplies.

Because of its widespread use and potential to harm human health, atrazine has become the subject of growing regulatory scrutiny and legal action.

What Company Produces Atrazine?

Atrazine is primarily produced by Syngenta, a global agrochemical company headquartered in Switzerland.

The herbicide was originally developed by CIBA-Geigy in the 1950s, a predecessor to Syngenta, and has remained one of the company’s flagship products.

Today, Syngenta manufactures atrazine under its own labels and also licenses it for use in a variety of combination herbicide products.

Although banned in dozens of countries, atrazine remains legal and widely used in the United States, particularly in corn production.

Syngenta continues to defend the safety of atrazine despite ongoing concerns about its links to cancer and endocrine disruption.

Common atrazine-containing brand names include:

• AAtrex® – Syngenta’s flagship atrazine herbicide for corn and sorghum.
• Bicep II Magnum® – A pre-emergent herbicide combining atrazine and metolachlor.
• Lumax® EZ – A broad-spectrum corn herbicide containing atrazine, mesotrione, and s-metolachlor.
• Lexar® EZ – Similar to Lumax, used for early season weed control in corn.
• Expert® Herbicide – A Syngenta mix for corn that includes atrazine and glyphosate.
• Gro-Mor Atrazine 4L – A liquid atrazine herbicide used in row crops.
• Atrazine 90 WDG – A water-dispersible granular formulation sold by various manufacturers.

These products are used in both agricultural and, to a lesser extent, turf and residential applications.

Health Risks Associated With Atrazine

Atrazine has been used in American agriculture for decades, but growing scientific and regulatory concern has raised serious questions about its long-term safety.

According to the U.S. Environmental Protection Agency (EPA), atrazine is one of the most frequently detected herbicides in drinking water and has been shown to cause endocrine disruption, which can interfere with hormone function and potentially lead to reproductive harm.

In 2025, the World Health Organization’s International Agency for Research on Cancer (IARC) classified atrazine as a probable human carcinogen, citing strong links to non-Hodgkin’s lymphoma and compelling animal studies.

Even at low levels, atrazine exposure has been associated with changes in the immune system, hormone imbalances, and developmental risks in children.

The EPA has acknowledged that prolonged exposure through water, skin contact, or inhalation may pose health risks, especially for farm workers and those living near treated fields.

Research also shows that atrazine doesn’t break down easily in the environment, meaning it can linger in soil and water for years after application.

While still legal in the U.S., atrazine has been banned in over 35 countries, including all members of the European Union, due to its health and environmental impact.

These findings have led public health experts and legal professionals to take a closer look at atrazine’s role in serious illnesses like cancer.

Atrazine Linked to Non-Hodgkin’s Lymphoma Risk

Scientific research increasingly shows a compelling link between atrazine exposure and an elevated risk of developing non-Hodgkin’s lymphoma (NHL), a serious cancer affecting the lymphatic system.

In 2025, the World Health Organization’s International Agency for Research on Cancer (IARC) officially reclassified atrazine as a Group 2A probable human carcinogen, citing “limited evidence in humans” and “sufficient evidence in animals” that it can cause cancer, particularly NHL.

This marked a significant shift in how global health authorities view the risks of long-term atrazine exposure, especially for people working in agriculture or groundskeeping.

Multiple epidemiological studies reviewed by IARC have shown that farmers and pesticide applicators who use atrazine regularly face significantly higher rates of NHL than those who do not.

In particular, one study cited by IARC found that farmworkers with the highest levels of atrazine exposure had more than double the risk of developing a certain subtype of non-Hodgkin’s lymphoma.

Another key finding comes from genetic research showing that NHL cases linked to atrazine exposure often share a specific chromosomal translocation t(14;18), a common biomarker found in lymphomas potentially caused by environmental factors.

On a biological level, atrazine is known to cause endocrine disruption, meaning it interferes with hormones that regulate key cellular processes.

It also weakens the immune system, which normally plays a role in identifying and destroying abnormal or cancerous cells.

Laboratory studies have shown that atrazine can cause DNA damage, oxidative stress, and inflammation, all of which are hallmarks of cancer development.

Other Health Concerns Associated with Atrazine Exposure

In addition to its potential link to non-Hodgkin’s lymphoma, atrazine has been associated with a range of other serious health effects, especially in individuals who are chronically exposed.

Research shows that pesticide exposures, including atrazine, can interfere with normal hormonal function and affect multiple organ systems.

Pregnant women and young children may be particularly vulnerable, as studies have linked atrazine in drinking water to adverse birth outcomes and developmental issues.

Animal studies have documented changes in liver weight and function following prolonged atrazine exposure.

Other findings suggest decreased body weight in offspring and reproductive disruptions when parents are exposed during critical developmental periods.

These concerns have led public health organizations to question the safety of continued atrazine use, even at low doses.

Other potential health effects of atrazine exposure may include:

• Hormonal imbalances due to endocrine disruption
• Increased risk of birth defects in children born to exposed mothers
• Irregular menstrual cycles and reproductive issues in women
• Reduced sperm count and fertility problems in men
• Altered liver function and increased liver weight in lab animals
• Decreased body weight in fetuses and newborns
• Developmental delays and neurological concerns in early life

While more research is needed to understand the full impact, existing studies suggest that atrazine poses a health threat beyond cancer alone.

These risks are especially concerning for communities reliant on well water or individuals who live or work near treated areas.

Who Is at Risk From Exposure to Atrazine?

Atrazine is most commonly used in agriculture to control broadleaf and grassy weeds, particularly in crops like corn, sorghum, and sugarcane.

According to the U.S. Department of Agriculture and Environmental Protection Agency (EPA), over 70 million tons of atrazine are applied each year across U.S. farmland, making it one of the most heavily used herbicides in the country.

It is typically applied as a pre-emergent or post-emergent spray, either directly onto soil or crops using tractor-mounted booms or aerial application methods.

Once applied, atrazine can leach into groundwater, run off into nearby streams, or become airborne and drift to surrounding areas, posing risks to individuals far beyond the immediate site of use.

Midwestern states like Iowa, Illinois, Indiana, Nebraska, and Ohio use the most atrazine because of their large corn production.

Southern states such as Texas and Louisiana also see heavy use, particularly in sugarcane and sorghum fields.

In these areas, people may be exposed through direct handling, contaminated groundwater, or residue on crops and soil. This section will explore which workers and communities may face the greatest risks.

Agricultural Workers and Pesticide Applicators

Farmers and field workers who handle, mix, or spray atrazine face some of the highest levels of exposure.

These individuals often come into direct contact with concentrated forms of the herbicide, especially during application or equipment cleanup.

Without proper protective gear or safety protocols, exposure through skin, inhalation, or accidental ingestion is a serious concern.

Over time, this kind of repeated contact can significantly increase the risk of developing health problems, including non-Hodgkin’s lymphoma.

High-risk occupations may include:

• Crop farmers (especially corn, sorghum, and sugarcane)
• Licensed pesticide applicators
• Herbicide and chemical sprayer operators
• Farm equipment operators responsible for spraying
• Agricultural chemical mixing/loading personnel
• Farmhands and laborers working in recently treated fields
• Agricultural maintenance workers cleaning tanks, hoses, or sprayers

Farmworkers and Rural Families

Farmworkers who plant, weed, or harvest crops in fields treated with atrazine may be exposed even if they don’t handle the chemical directly.

Residue can remain on plants, soil, and equipment for days or weeks after application, leading to skin contact or inhalation during routine tasks.

In many cases, workers are not given adequate protective equipment or training to avoid these risks.

Families who live on or near farms may also face exposure through pesticide drift, contaminated dust, or atrazine in well water.

Children are particularly vulnerable due to their developing immune and hormonal systems.

Long-term, low-level exposure in these settings can still contribute to serious health concerns, including increased cancer risk.

Groundskeepers and Turf Management Professionals

Atrazine isn’t limited to farmland.

It’s also used to control weeds on golf courses, athletic fields, parks, and other managed green spaces.

Groundskeepers and turf managers who apply or maintain treated areas may be exposed through spraying, mixing, or contact with recently treated turf.

These workers often operate in enclosed areas or near the public, increasing the risk of inhalation or skin exposure.

Over time, repeated contact with atrazine can lead to cumulative health risks, especially without consistent use of protective gear.

Although less publicized than agricultural exposure, these occupations may still face meaningful long-term hazards.

Residential Exposure: Limited but Not Impossible

While most atrazine exposure occurs in agricultural or commercial settings, residential contact can still happen under certain conditions.

Homeowners who used atrazine-based weed killers on their lawns or gardens (especially in older formulations) may have experienced direct exposure during mixing or spraying.

Living near large farming operations can also increase the risk of pesticide drift or groundwater contamination, particularly in rural communities that rely on private wells.

Although less common, this type of environmental exposure may still pose health risks over time.

For individuals diagnosed with non-Hodgkin’s lymphoma, a history of repeated contact with atrazine at home may be relevant to potential legal claims.

Past Legal Actions Involving Atrazine

Atrazine has been the focus of several major legal challenges over the past two decades, most notably involving widespread water contamination.

In 2012, Syngenta agreed to pay a $105 million settlement to resolve a class action lawsuit filed by more than 1,000 community water systems across the Midwest, including the City of Greenville, Illinois.

The lawsuit alleged that Syngenta knowingly allowed atrazine to pollute public drinking water supplies, forcing municipalities to shoulder the cost of removal.

Though the company did not admit wrongdoing, the case highlighted how extensively atrazine had spread through rivers, streams, and groundwater across farming regions.

In a separate line of legal actions, environmental and public health groups (including the Center for Biological Diversity and Pesticide Action Network) have sued the U.S. Environmental Protection Agency (EPA) for failing to ban or adequately regulate atrazine despite growing scientific evidence of health and ecological risks.

These lawsuits argue that the EPA’s reapproval of atrazine in 2020 ignored data on endocrine disruption, wildlife harm, and cancer risk, particularly affecting vulnerable communities and endangered species.

Do You Qualify for an Atrazine Exposure Claim?

You may qualify for an atrazine exposure claim if you have a documented history of repeated atrazine contact and a diagnosis of non-Hodgkin’s lymphoma.

The strongest cases often involve occupational exposure, such as mixing, loading, spraying, or working in areas where atrazine was applied over multiple seasons or years.

Eligibility often depends on whether atrazine exposure can be tied to a job, worksite, or routine responsibilities, not just a one-time event.

Lawyers also look at how exposure likely occurred, including direct skin contact, inhalation of spray or mist, or handling contaminated equipment and clothing.

A confirmed medical diagnosis, treatment timeline, and pathology records are typically needed to support the cancer claim.

Work records, pesticide application logs, job descriptions, or witness statements can help establish the exposure history.

Some cases may involve environmental exposure, such as living near heavy agricultural spraying or relying on a private well in an area with known atrazine use, but these claims can be harder to prove.

A case review can help determine whether your exposure history and diagnosis fit the criteria being investigated.

Evidence in Atrazine Exposure Lawsuits

Evidence is often the difference between a claim that moves forward and one that stalls early.

Lawyers use records and documentation to show when and how exposure happened, then connect that history to a non-Hodgkin’s lymphoma diagnosis.

An attorney can help obtain medical records, track down work and pesticide documentation, and preserve supporting proof before it disappears.

That matters in cases involving older job sites, changing employers, and products applied years before symptoms appeared.

Evidence that may support an atrazine exposure claim includes:

• Pathology reports confirming non-Hodgkin’s lymphoma and subtype details
• Medical records showing diagnosis date, treatment history, and prognosis
• Employment records, job descriptions, union records, or W-2s showing where you worked
• Pesticide application logs, spray records, or farm management records listing atrazine use
• Purchase receipts, invoices, or distributor records for atrazine products
• Applicator licenses, training records, or safety compliance documentation
• Statements from coworkers, supervisors, or family members confirming handling or spraying practices
• Photos of equipment, product containers, labels, or storage areas
• Maintenance records for sprayers, tanks, hoses, and protective equipment
• Property or well testing records, water quality reports, or local contamination data when relevant

Potential Compensation in an Atrazine Lawsuit

Damages are the losses a person can seek to recover in a lawsuit after a harmful exposure and resulting illness.

In an atrazine case involving non-Hodgkin’s lymphoma, damages are meant to reflect both the financial impact of treatment and the personal toll of living with cancer.

Lawyers evaluate medical records, billing statements, employment history, and expert input to estimate how the illness has affected a person’s life now and into the future.

The goal is to present a clear, well-supported valuation that accounts for both out-of-pocket costs and the broader consequences of the diagnosis.

Potential damages in an atrazine lawsuit may include:

• Past and future medical expenses (hospital care, chemotherapy, radiation, medications)
• Costs of ongoing monitoring, follow-up care, and specialist treatment
• Lost wages and reduced earning capacity
• Disability or inability to return to the same work
• Out-of-pocket expenses (travel for treatment, lodging, home care, medical equipment)
• Physical pain and treatment-related side effects
• Emotional distress, anxiety, and loss of enjoyment of life
• Loss of consortium for a spouse in some cases
• Wrongful death damages for surviving family members, when applicable
