TCE & Kidney Cancer FAQ

If you or a loved one developed kidney cancer after working with or living near trichloroethylene (TCE), you may have the right to pursue compensation. The science is clear: both the U.S. Environmental Protection Agency and the International Agency for Research on Cancer have formally classified TCE as a substance that causes kidney cancer in humans. Below, we answer the questions we hear most often from potential clients.

Boling Firm handles TCE kidney cancer cases on a contingency fee basis, you pay nothing unless we recover compensation for you. Contact your kidney cancer lawyer today at 1-800-799-7914 for a free consultation.

The Science: Does TCE Cause Kidney Cancer?

Is there scientific proof that TCE causes kidney cancer?

Yes. The evidence is extensive, consistent, and comes from multiple independent scientific bodies.

• The U.S. EPA's 2011 Integrated Risk Information System (IRIS) assessment — the result of more than 20 years of analysis — classified TCE as "carcinogenic to humans by all routes of exposure," with kidney cancer identified as the strongest link.
• The International Agency for Research on Cancer (IARC) upgraded TCE to a Group 1 known human carcinogen in 2014, citing kidney cancer as the primary basis.
• The National Toxicology Program (NTP) lists TCE as a known human carcinogen in its Report on Carcinogens, noting that increased kidney cancer risk was observed consistently across studies with higher exposure levels.

This level of scientific consensus — multiple major agencies independently reaching the same conclusion — is the same standard used to hold companies accountable in court.

How does TCE actually cause kidney cancer?

TCE is lipophilic, meaning it accumulates in fatty tissue and organs. After entering the body through inhalation, ingestion, or skin contact, it is metabolized primarily in the liver. Its toxic byproducts — known as cysteine-S-conjugates — are then concentrated and activated in the kidneys, where they cause direct DNA damage.

Research shows these metabolites can:

• Mutate tumor suppressor genes in renal cells (including the VHL gene, commonly mutated in kidney cancer)
• Trigger oxidative stress that disrupts normal cellular function
• Suppress the immune system's ability to identify and destroy cancerous cells

The specific cancer most strongly associated with TCE exposure is renal cell carcinoma (RCC), which accounts for roughly 90% of all kidney cancers.

What do large-scale population studies show?

The epidemiological record is extensive. Meta-analyses covering dozens of cohort and case-control studies across multiple countries consistently show elevated rates of kidney cancer among people with documented TCE exposure — especially workers in metal degreasing, dry cleaning, aerospace, and electronics manufacturing.

A population-based study published in Anticancer Research found a significant dose-response relationship between industrial TCE releases and kidney cancer mortality across U.S. counties. A separate study focused on contaminated groundwater in New Hampshire identified elevated kidney cancer rates in communities whose private wells were affected by TCE contamination.

The NTP concluded that epidemiological studies demonstrate a causal relationship between TCE exposure and kidney cancer "based on consistent evidence of increased risk across studies with different study designs, in different geographical areas, and in different settings."

Is TCE now banned in the United States?

In 2024, the EPA issued a final rule under the Toxic Substances Control Act (TSCA) banning most industrial and commercial uses of TCE, with most uses targeted for elimination by September 2025. Limited exemptions were granted for certain military and medical applications, with some extending up to 20 years.

The ban has faced legal and political challenges and remains subject to ongoing regulatory review as of 2026. Regardless of its status, TCE contamination from decades of past use persists in soil, groundwater, and building air at thousands of sites across the country — and continues to harm people today.

TCE Exposure: Who Is at Risk?

Which industries and jobs carry the greatest TCE exposure risk?

TCE was used extensively as an industrial degreaser and cleaning solvent from the 1940s through the 2000s. Workers in the following industries face or have faced elevated risk:

• Metal fabrication and machining (vapor degreasing of parts)
• Aerospace and defense manufacturing
• Automotive manufacturing and repair
• Dry cleaning and textile finishing
• Electronics and semiconductor manufacturing
• Military installations
• Printing, adhesives, and paint manufacturing

Even intermittent or part-time exposure may be legally significant, particularly over an extended period or in high-concentration environments without adequate ventilation or protective equipment.

Can people be exposed to TCE through drinking water or their home?

Yes, and this is a serious, underrecognized pathway. TCE degrades slowly in soil and groundwater, migrating from industrial sites and landfills into residential water supplies over time, particularly private wells. TCE has been detected at more than 1,000 EPA-designated Superfund sites. Many TCE superfund sites in Louisiana and Texas.

Common environmental exposure routes include:

• Contaminated drinking water from private wells or municipal systems near TCE sources
• Vapor intrusion — TCE vapors from contaminated groundwater rise through soil and enter homes through foundation cracks, accumulating in indoor air
• Showering and bathing with TCE-contaminated hot water (inhalation of steam)
• Proximity to Superfund sites or former industrial facilities

The EPA has set a maximum contaminant level goal of zero for TCE in drinking water, reflecting the agency's position that no level of exposure is safe.

Your Legal Rights and Options

Who can be held responsible for TCE-related kidney cancer?

Liability depends on how and where the exposure occurred. Potentially responsible parties include:

• Employers who used TCE without adequate safety protocols or failed to warn workers of known risks
• TCE manufacturers and chemical suppliers who were aware of health risks but failed to adequately disclose them
• Industrial operators and property owners who contaminated groundwater or soil
• Companies responsible for Superfund sites affecting residential communities
• Government entities responsible for contaminated military installations

Internal industry documents have shown that the dangers of TCE were known to manufacturers long before adequate warnings were issued to workers or the public. This history of concealment is often central to successful TCE litigation.

What compensation may be available in a TCE kidney cancer case?

Victims may be entitled to recover damages for:

• Past and future medical expenses (surgery, chemotherapy, dialysis, ongoing care)
• Lost wages and reduced earning capacity
• Pain and suffering and emotional distress
• Loss of consortium (for spouses and family members)
• Wrongful death damages if the victim has passed away

In cases involving companies that knowingly concealed safety risks, courts may also award punitive damages designed to deter future misconduct.

How long do I have to file a TCE lawsuit?

Statutes of limitations — the legal deadlines for filing — vary by state. In most toxic tort cases, the clock begins when the victim knew or reasonably should have known that their illness was linked to TCE exposure, not necessarily from the date of exposure itself. This is known as the discovery rule.

Because kidney cancer can take years or decades to develop after initial TCE exposure, courts have sometimes allowed claims that appear time-barred on their face. Even so, acting promptly is critical — evidence can be lost, witnesses' memories fade, and some jurisdictions impose strict deadlines regardless of when the connection was discovered.

If you have been diagnosed with kidney cancer and have a history of TCE exposure, you should speak with an attorney as soon as possible.

How do I prove my kidney cancer was caused by TCE?

A successful TCE kidney cancer case requires establishing two things: that you were exposed to TCE at a meaningful level and duration, and that this exposure was a contributing cause of your kidney cancer. Your legal team will work with:

• Occupational exposure experts to reconstruct workplace TCE levels using employment records and industrial hygiene data
• Medical oncologists and toxicologists to provide expert testimony linking your renal cell carcinoma to TCE
• Environmental scientists (in groundwater cases) to document TCE concentrations at the relevant location and time period
• Your medical records and pathology reports confirming diagnosis, tumor type, and staging

The strong scientific consensus — including the EPA's and IARC's formal carcinogen classifications — provides a powerful foundation for expert testimony in these cases.

What if a family member died from TCE-related kidney cancer?

If your loved one passed away from kidney cancer linked to TCE exposure, surviving family members may be able to pursue a wrongful death claim. These claims can seek compensation for the deceased's medical expenses, lost future income, and the family's loss of companionship and financial support.

Wrongful death statutes vary by state, and the family members who may bring a claim — spouses, children, parents — also differ by jurisdiction. Deadlines in wrongful death cases are often shorter than in personal injury cases, so it is important to consult an attorney promptly.
