Los Angeles PFAS Forever Chemicals and Childhood Leukemia: Your Legal Rights After the UC Irvine Study
You are sitting at a kitchen table in Los Angeles County, and your child has cancer. Acute lymphoblastic leukemia — the most common childhood cancer there is. You may have spent two years in and out of hospitals. You may still be there. And now you are reading that researchers found “forever chemicals” in the blood of newborns in Los Angeles County, and that the children who had more of those chemicals in their blood at birth were more likely to develop the exact leukemia your child is fighting.
The questions come all at once. Was it the water? Was it something I used while I was pregnant? Could this have been prevented? And the one that keeps you up: did a company know, and say nothing?
We are Attorney911 — The Manginello Law Firm. We handle toxic tort and environmental exposure cases, and we are writing this page for one person: the parent who just found this study and needs to understand, in plain language, what it means for their family’s legal rights. This page is legal information, not legal advice, and contacting us is free and confidential. Nothing here states or implies that we represent any family involved in this research or this incident. What we can do — and what we do below — is tell you exactly how California law treats a case like this, what evidence is dying right now that you may need, what the science does and does not yet prove, and what an honest evaluation of your situation looks like.
What the Research Found: PFAS in Newborn Blood and Childhood Leukemia
A peer-reviewed study, supported by a National Institutes of Health grant and published in a Nature-affiliated journal, analyzed dried blood spots collected from newborns born in Los Angeles County between 2000 and 2015. The research team compared 125 children who were diagnosed with acute lymphoblastic leukemia against 219 children without cancer. What they found:
- 17 PFAS compounds were detected in the newborn blood samples. Two of them — PFOA and PFOS — appeared at the highest levels.
- Children with higher levels of PFOA and PFOS had increased odds of developing leukemia. The risk also appeared to rise with combined exposure to both chemicals.
- 26 additional, rarely studied PFAS compounds were identified, several showing similar risk patterns.
- The study measured actual PFAS present at birth, rather than estimating exposure from drinking water — capturing what researchers called “a critical window of development.”
The study’s corresponding author described the significance plainly:
“By capturing exposures during a critical window of development, we are gaining a clearer picture of how environmental contaminants may contribute to childhood cancer risk.”
This research builds on earlier work by the same team, which tracked PFAS exposure in drinking water among more than 40,000 California children and linked higher PFOA and PFOS levels to increased risk of several childhood cancers, including acute myeloid leukemia and Wilms tumor.
One thing the study does not do: it does not prove cause and effect. The researchers state this explicitly. The study found a statistical association — a meaningful one, measured directly in newborn blood for the first time — but association is not the same as legal causation. That distinction is the single most important fact in this entire page, and we return to it throughout. Any lawyer who tells you this study alone proves your child’s leukemia was caused by PFAS is not being honest with you.
What Are PFAS “Forever Chemicals”?
PFAS — per- and polyfluoroalkyl substances — are a group of thousands of synthetic compounds that have been used since the 1940s in consumer products and industrial processes. They are called “forever chemicals” because they do not break down. Not in the environment. Not in water. Not in the human body. They accumulate.
PFAS are found in drinking water, food and beverage containers, nonstick cookware, stain-resistant fabrics, firefighting foam, and hundreds of everyday items. The two most studied — PFOA and PFOS — have been phased out of manufacturing in the United States but persist in the environment and in people’s blood. Other PFAS compounds, including newer replacements, are less studied but are now showing up in the same samples.
The federal government has spoken clearly about the danger. In April 2024, the EPA finalized national drinking water standards setting the legal limit for PFOA and PFOS at 4.0 parts per trillion — a number so small it is roughly equivalent to a single drop spread across twenty Olympic swimming pools. More significantly, EPA set the health-based goal — the Maximum Contaminant Level Goal — at zero. That means the federal government determined there is no safe threshold of these chemicals in drinking water. No amount is considered risk-free.
In May 2024, the EPA designated PFOA and PFOS as hazardous substances under CERCLA — the Superfund law. Any entity that releases a pound or more of either chemical in a 24-hour period must now report that release to federal authorities. And under the Toxic Substances Control Act, manufacturers must report PFAS production, uses, exposures, and known hazards going back to 2011 — creating a discoverable paper trail of what these companies knew and when they knew it.
The world’s leading cancer authority has also spoken. The International Agency for Research on Cancer classified PFOA as Group 1 — carcinogenic to humans — and PFOS as Group 2B — possibly carcinogenic to humans. That IARC classification does not prove PFAS caused any individual person’s cancer. But it establishes that the scientific community recognizes these compounds as cancer-causing agents — which is the foundation any toxic tort case must build upon.
How PFAS Reaches Los Angeles County Families
Los Angeles County is the most populous county in the United States — over 10 million residents served by a complex network of drinking water sources. Your water may have come from the Colorado River Aqueduct, the State Water Project, local groundwater basins beneath the San Fernando Valley or the Central Basin, or imported supplies. Each source has its own contamination profile. Each is managed by a different agency or utility.
PFAS contamination in California has been documented near military installations, airports, chrome plating facilities, industrial sites, and wastewater treatment plants. Both Los Angeles and Orange Counties have identified PFAS in groundwater systems. The Orange County Water District has invested heavily in PFAS treatment infrastructure in response to detected contamination in its groundwater basin — a public acknowledgment that the problem is real, measurable, and present in Southern California water.
The exposure pathway for a child who develops leukemia may look like this: a mother drinks water from a contaminated source during pregnancy. PFAS crosses the placenta. The chemical is present in the child’s blood at birth — which is exactly what the study measured in those dried blood spots. The exposure continues through breast milk, through formula mixed with tap water, through food prepared with contaminated water, through household dust from stain-treated fabrics and food packaging. The chemicals do not leave. They build.
For families who lived near a military base, an airport, an industrial discharge site, or a wastewater treatment plant in Los Angeles County during pregnancy or early childhood, the exposure pathway may be traceable to a specific contamination source — which is the threshold any individual claim must cross. But tracing that pathway requires evidence, and the evidence is perishable.
California’s Legal Framework for Toxic Tort Claims
California maintains one of the most developed toxic tort frameworks in the country. If your child’s leukemia can be connected to PFAS exposure from a specific source, California law recognizes multiple theories of liability:
Strict product liability — design defect. PFAS chemicals were designed to be persistent and bioaccumulative. The foreseeability that these molecular properties would lead to environmental contamination and human bioaccumulation — creating health risks — is the core defect theory against manufacturers. The chemicals do not break down by design. That design is the defect.
Strict product liability — failure to warn. Manufacturers and distributors failed to adequately warn consumers, communities, and regulators about carcinogenic and developmental risks of PFAS exposure, particularly to developing fetuses and newborns. California’s Proposition 65 — the Safe Drinking Water and Toxic Enforcement Act — requires warnings for exposures to chemicals known to cause cancer or reproductive harm, and has been a vehicle for PFAS-related enforcement actions.
Negligence. Failure to test for health effects before widespread commercial deployment. Failure to disclose adverse findings. Negligent discharge of PFAS into environmental media. Failure to implement available remediation or alternative chemistries when the hazards became known.
Medical monitoring. Children with confirmed elevated PFAS blood levels at birth may be entitled to the cost of enhanced medical surveillance for early cancer detection. California courts have recognized medical monitoring as a cognizable damages category in toxic exposure cases.
Nuisance and trespass. Contamination of public and private water supplies with persistent chemicals that cross property boundaries and interfere with the public right to safe drinking water.
Negligence per se. Violations of California State Water Resources Control Board PFAS notification and response levels, or violations of EPA drinking water standards, may serve as predicate regulatory violations that strengthen a negligence claim.
One critical point: California’s MICRA damage cap does not apply to toxic tort claims. MICRA — the Medical Injury Compensation Reform Act — limits non-economic damages in medical malpractice actions. Toxic tort is not medical malpractice. Non-economic damages in a PFAS cancer case — your child’s pain and suffering, fear of recurrence, loss of developmental milestones — are not subject to MICRA’s limitations. And California does not impose a statutory cap on punitive damages in toxic tort cases. The state’s substantial-wealth factor in punitive determinations can produce significant awards against major chemical manufacturers — if the evidence supports it.
Who Can Be Held Accountable: The Defendant Map
A PFAS leukemia case in Los Angeles County may involve multiple categories of defendants. Identifying the right ones — and tracing the exposure pathway to each — is the threshold work of any claim.
PFAS chemical manufacturers. The companies that designed, manufactured, and distributed PFOA, PFOS, and related compounds. These are the deepest-pocket defendants and the ones against whom punitive damages theories are strongest. Public record confirms that major PFAS manufacturers have faced extensive litigation and regulatory scrutiny. Under the Toxic Substances Control Act, manufacturers were required to report PFAS uses, production volumes, disposal, exposures, and known hazards going back to 2011 — which means the question of what these companies knew, and when, may be answerable from their own mandatory filings.
Industrial dischargers. Facilities whose PFAS-containing waste streams contaminated drinking water sources serving the study population. Military installations, airports, chrome plating operations, and industrial facilities in Los Angeles County are all potential sources. Source identification through environmental forensics — tracing the chemical signature of the PFAS in a specific water supply back to a specific facility’s discharge — is a required threshold for individual claims.
Public water utilities. The systems that served your family’s water. Potential claims arise when a utility distributed PFAS-contaminated water with knowledge or constructive knowledge of contamination. Utility liability depends on the source of contamination, the utility’s testing practices, and the timing of its awareness relative to California’s evolving notification levels.
Manufacturers of PFAS-containing consumer products. Nonstick cookware, stain-resistant fabrics, food and beverage containers — products that contributed to population-wide exposure. Product liability theories may apply, but isolating the exposure dose from any individual consumer product is a demanding evidentiary challenge.
The corporate structure of PFAS manufacturing is itself a battleground. Chemical companies have historically operated through layered subsidiaries, spinoffs holding legacy liability, and complex corporate reorganizations — the same shell-game structure seen in other mass torts. Naming the right entity — the one that actually manufactured the chemical, not a holding company with no operational role — is foundational work. For a deeper look at how we approach this, our toxic tort claim practice page covers the defendant-identification process.
The Central Battle: Causation Under California’s Expert Evidence Rules
This is where every PFAS leukemia case is won or lost. The study found an association. The law requires causation. And the distance between those two words is the entire case.
California’s expert evidence standard — the Kelly/Sargon framework — governs what scientific testimony a jury is allowed to hear. Under this standard, a trial judge serves as a gatekeeper, evaluating whether expert testimony is based on sound methodology, whether it is relevant to the specific facts of the case, and whether it rests on a reliable factual foundation. The study’s own statement that it “does not prove cause and effect” is the defense’s primary weapon — it will be quoted in every motion to dismiss and every motion for summary judgment.
A plaintiff strategy must build a multi-study general causation foundation that goes beyond any single piece of research:
- The research team’s prior California drinking water study (40,000+ children, linking PFOA/PFOS to multiple childhood cancers)
- The broader epidemiological literature on PFAS carcinogenicity
- Toxicological mechanism evidence — immunomodulation, endocrine disruption, genotoxicity — the biological pathways by which PFAS could cause cancer at the cellular level
- Regulatory findings from EPA and California agencies — including the MCLG of zero, the CERCLA hazardous substance designation, and IARC’s Group 1 classification of PFOA
- The C8 Science Panel findings — which found a “probable link” between PFOA and certain cancers (kidney and testicular), though childhood leukemia was not specifically on that panel’s list
Specific causation is the second, harder hurdle. Even if general causation is established — even if a jury accepts that PFAS can cause childhood leukemia — the plaintiff must prove that this specific child’s measured PFAS levels were a substantial contributing factor to their specific leukemia. This requires board-certified pediatric oncology and environmental toxicology experts who can opine on the individual child’s exposure, while conducting a rigorous confounder screen that excludes alternative explanations: genetic predisposition, Down syndrome (which carries elevated leukemia risk), ionizing radiation exposure, prior chemotherapy, and other known ALL risk factors.
Honest assessment: the defense will argue that the science is not mature enough to support individual causation. They will bring their own experts. They will point to the study’s own disclaimer. They will argue that childhood leukemia has causes science does not yet fully understand — that “idiopathic” (unknown cause) is the most common classification. These are real arguments, not straw men, and any lawyer who dismisses them is not preparing you for what this fight actually looks like.
The Medicine: Childhood Acute Lymphoblastic Leukemia
Acute lymphoblastic leukemia is the most common childhood cancer. Treatment typically spans two to three years and proceeds in phases:
Induction chemotherapy — the first month, aimed at driving the leukemia into remission. Hospitalization, intensive chemotherapy, blood transfusions, management of side effects. The goal is to eliminate detectable leukemia cells from the bone marrow.
Consolidation chemotherapy — additional cycles to eradicate residual disease, often including intrathecal chemotherapy (delivered into the spinal fluid) to prevent central nervous system relapse.
Maintenance chemotherapy — lower-intensity treatment continuing for approximately two to two and a half years, typically oral medications with periodic intravenous and intrathecal doses.
For high-risk cases, treatment may escalate to stem cell transplantation — replacing the child’s diseased bone marrow with healthy stem cells from a donor. This carries its own severe risks: graft-versus-host disease, prolonged immunosuppression, months of hospitalization, and a mortality rate from the procedure itself.
The long-term late effects of ALL treatment are where the damages truly compound. Even children who are cured — and survival rates have improved dramatically — face:
– Secondary malignancies caused by the chemotherapy itself
– Cardiac toxicity from anthracycline chemotherapy drugs, which can damage the heart muscle years after treatment ends
– Neurocognitive deficits from intrathecal chemotherapy and cranial radiation — learning disabilities, memory problems, attention deficits that persist into adulthood
– Endocrine disruption — growth problems, thyroid dysfunction, fertility impairment
– Psychological trauma — anxiety, depression, post-traumatic stress from years of treatment, procedures, and hospital isolation
A family watching this happen to their child is watching years of their life be consumed — and the financial cost is staggering. ALL treatment can run from hundreds of thousands to over a million dollars depending on intensity, complications, and whether transplant is required. Parental lost wages during caregiving are real. The child’s potential lost earning capacity from treatment-related educational disruption and long-term health effects is real. And the non-economic damages — the pain, the fear, the lost childhood, the milestones missed — are unbounded by MICRA in the toxic tort context.
For families who have lost a child, California provides separate survival and wrongful death damage categories. Survival damages cover the child’s pre-death economic losses and pain and suffering. Wrongful death damages cover the family’s loss of financial support, companionship, and consortium. Our wrongful death claim page addresses these categories in more detail.
What Your Case May Be Worth
We will be direct with you, because honesty is the only thing that serves a family in this situation. The case value range for an individual PFAS childhood leukemia claim is extraordinarily wide — from $0 to $5,000,000 or more per plaintiff — and the reasons for that width are the same reasons this page exists.
Why a case could be worth $0: The study does not prove causation. If general causation expert testimony does not survive the Kelly/Sargon challenge — if the court rules that the science is not yet reliable enough to support an opinion that PFAS causes childhood leukemia — the case is dismissed before it reaches a jury. If specific causation cannot be established — if the child’s measured PFAS levels cannot be tied to a specific defendant’s products or discharges — there is no one to hold accountable. If the statute of limitations has run — if the family waited too long after discovering the link — the courthouse door is closed.
Why a case could be worth $5,000,000 or more: If general causation survives — if the multi-study foundation, the IARC classification, the EPA regulatory findings, and the toxicological mechanism evidence combine to produce admissible expert testimony — and if specific causation is supported by measured PFAS levels in the child’s newborn blood spot, a clean confounder screen, and source identification linking the exposure to a specific contaminated water system or defendant’s discharge — then the damages are substantial. Past and future medical expenses reaching seven figures. Parental lost wages. The child’s lost earning capacity. Non-economic damages unbounded by MICRA. And punitive damages — which are uncapped in California toxic tort cases — if discovery reveals that PFAS manufacturers possessed internal health-risk data predating public regulatory action and continued production without adequate warning.
The honest truth: the scientific literature is still developing. The association found in this study is meaningful and concerning, but it is not yet the kind of scientific consensus that makes individual causation straightforward. Cases with the strongest exposure-source tracing, the most compelling alternative-causation exclusion, and the clearest documentary support for manufacturer knowledge will be the ones that reach significant value. Cases without those elements may not survive.
Mediation or settlement discussions should be deferred until general causation expert testimony survives expert-evidence challenges. Premature settlement demands anchored on association-only evidence will be dismissed by sophisticated defendants. The path to value runs through the courtroom doors first, not the settlement table.
Past results depend on the facts of each case and do not guarantee future outcomes.
Evidence That Is Dying Right Now
This is the section we wish every family would read the day they find this study, not six months later. The evidence that could connect your child’s leukemia to PFAS exposure is perishable — and some of it is on a clock that may already be running.
California newborn screening dried blood spot cards. If your child was born in California, the state’s newborn screening program collected a dried blood spot card at birth. These cards contain actual, measurable PFAS levels — the most direct evidence of early-life exposure specific to your individual child. This is the same type of sample the research team analyzed. California retains these samples, but retention policies and access protocols are subject to regulatory and legislative change. California has specific statutory provisions governing retention and use of residual dried blood spots that may affect availability for litigation. Confirming preservation and the legal access framework is something that should happen early — not after a policy change closes the door.
Historical water utility testing and operational records. These records establish which water sources served your specific geographic zone during the years your family lived there, and whether PFAS contamination was detected, known, or undisclosed. Systematic PFAS testing is relatively recent — pre-2013 testing data is sparse, and older operational records may be subject to document retention schedules that permit destruction. The utility that served your home may or may not still have the records showing what was in your water when you were pregnant.
Environmental site investigation records. Records from potential PFAS source locations in Los Angeles County — military installations, airports, industrial facilities, wastewater treatment plants — identify specific contamination sources and pathways. These records are maintained under various federal and state regulatory frameworks with differing retention requirements. Remediation activities may alter or destroy environmental evidence over time.
PFAS manufacturer internal corporate documents. The core punitive-damages evidence — showing whether manufacturers possessed or should have possessed knowledge of carcinogenic risks before continuing production and distribution. Substantial corporate document troves have been produced in existing PFAS litigation and MDL proceedings, but much remains subject to protective orders. Access typically requires litigation participation or specific court intervention.
Residential history and water source documentation. Your family’s records — lease histories, utility billing records, school enrollment documents — establish the exposure pathway and timeline linking your child’s residence and water supply to identified contamination sources. These are the records families may discard over time, not realizing they are evidence. Old lease agreements. Water bills. Even photographs that show where you lived. Securing these early preserves the exposure narrative before it fades.
Medical records. Your child’s complete treatment history — diagnosis, treatment phases, complications, hospitalizations, long-term effects, current status — is the damages spine. These are generally more durable than the exposure records, but they should be assembled completely and early.
The fastest-dying evidence drives the urgency. Water utility records, residential history documents, and any environmental samples that might still exist are the records most likely to be lost to time, policy, or routine destruction. The preservation letter that freezes these records goes out the day you call a lawyer — not after you have finished thinking about it.
The Corporate Playbook: What PFAS Manufacturers Will Do
If you file a PFAS leukemia claim, you will face sophisticated corporate defendants with armies of lawyers who have been defending PFAS litigation for years. Here are the plays they will run, and how each is countered:
Play 1: “The science shows association, not causation.” The defense will quote the study’s own disclaimer — “does not prove cause and effect” — in every motion they file. They will argue that a single epidemiological study showing a statistical association cannot support an expert opinion that PFAS caused any individual child’s leukemia.
Counter: Build a multi-study general causation foundation. Do not rely on this study alone. Combine it with the prior California drinking water study, the IARC Group 1 classification, the EPA’s MCLG of zero, the toxicological mechanism literature, and the regulatory findings. The defense wants to make this about one study. The case is about a body of evidence — and the body is growing.
Play 2: “You cannot identify which PFAS came from us.” PFAS is ubiquitous — it is in nearly everyone’s blood. The defense will argue that because exposure comes from countless sources, no individual manufacturer can be held responsible for any individual child’s exposure.
Counter: Environmental forensics and source identification. If your family lived in an area served by a water system contaminated from a specific, identifiable source — a military base that used firefighting foam, an industrial facility that discharged PFAS-laden wastewater — the exposure pathway can be traced. The defense’s “everyone has it” argument fails when your exposure was demonstrably elevated above background levels and traceable to a specific defendant’s conduct.
Play 3: “The child’s leukemia was genetic or idiopathic.” The defense will point to the fact that most childhood leukemia cases have no identified environmental cause — they are classified as idiopathic. They will argue that this child’s leukemia was more likely the result of random genetic events than of PFAS exposure.
Counter: A rigorous confounder screen by board-certified pediatric oncology experts. Exclude genetic syndromes (Down syndrome, Li-Fraumeni, etc.), prior radiation exposure, and other known risk factors. Then present the measured PFAS levels in the child’s own newborn blood, the dose-response relationship shown in the study, and the biological plausibility of the mechanism. The defense’s “it was probably random” argument weakens when you can show elevated exposure, a documented dose-response, and no alternative explanation.
Play 4: “We complied with all applicable regulations at the time.” The defense will argue that they manufactured and distributed PFAS in compliance with the regulatory standards that existed at the time of exposure.
Counter: CERCLA liability is strict, joint-and-several, and retroactive. It does not require a showing of fault or negligence — only that the defendant owned, operated, generated, or transported the hazardous substance. Compliance with regulatory standards that did not yet exist is not a defense to strict liability. And under failure-to-warn theory, the question is not whether the company followed the rules — it is whether the company warned about dangers it knew or should have known about, regardless of what the regulations required.
Play 5: Delay, deny, and wait for the science to settle. The defense may calculate that the best strategy is to drag proceedings out, hoping that the scientific literature either fails to mature or that courts rule against general causation before the case reaches trial.
Counter: This is why mediation should be deferred until general causation survives expert challenges — but also why the case must be filed and prosecuted aggressively within the statute of limitations. Waiting is the defense’s strategy, not the plaintiff’s. The preservation letters, the records demands, the expert disclosures — all of these move on the plaintiff’s timeline, not the defense’s.
How Long You Have: Statute of Limitations in California
California’s statute of limitations for personal injury claims is two years — the same deadline that governs wrongful death actions. But in toxic tort cases, two forces extend that clock in ways that may matter enormously to your family.
The discovery rule. California applies the discovery rule for toxic exposure claims: the limitations clock does not start ticking on the date of exposure. It starts when the plaintiff discovers, or by reasonable diligence should discover, both the injury and its probable toxic cause. For a parent whose child was diagnosed with leukemia years ago, the clock may not have started until this study — or a similar scientific development — connected PFAS exposure to childhood leukemia in a way that a reasonable person would recognize. This is critical for families whose children were diagnosed years or even decades ago.
Minor tolling. For injuries to minors, California generally tolls the limitations period until the child reaches the age of majority — 18 years old. This means a child diagnosed with leukemia at age 3 may have until age 20 (or longer, depending on how the discovery rule interacts with minor tolling) to file a claim in their own name. The specific interaction between minor tolling, the discovery rule, and any toxic-exposure-specific limitations provisions requires careful jurisdictional analysis — and this is one of the first things we evaluate when a family calls.
The practical reality: Do not assume you have plenty of time, and do not assume you have missed the window. Both assumptions can be wrong. The only way to know where your family stands is to have the specific facts — your child’s date of birth, date of diagnosis, residential history, and when you first learned of the potential PFAS connection — evaluated against the current California rules. That evaluation is part of a free consultation.
For families whose children did not survive, California’s wrongful death statute of limitations is also two years, subject to its own discovery-rule considerations. Our wrongful death practice page addresses these deadlines in more detail.
What Families Should Do Now
Whether or not you ultimately pursue a claim, there are practical steps that every family in this situation should take — because the evidence you preserve now may matter later, and because the cost of preservation is zero.
Gather and organize medical records. Your child’s complete treatment history: diagnosis records, chemotherapy protocols, hospitalization records, transfusion records, imaging, pathology reports, long-term follow-up notes. These are the damages spine and they should be assembled in one place.
Document your residential history. Write down every address where you lived during pregnancy and your child’s early life, with dates. Include the water utility that served each address. Old lease agreements, mortgage documents, utility bills, and school enrollment forms are evidence — find them and keep them.
Preserve any correspondence with your water utility. If you ever received a water quality report, a contamination notice, a Proposition 65 warning, or any communication from your water provider about PFAS or water testing, keep it. If you never received such a notice, that fact itself may be relevant.
Do not sign anything from any insurance company, manufacturer, or utility. If you are contacted by anyone offering a settlement, a release, or asking you to sign a document related to PFAS exposure or your child’s health, do not sign without consulting a lawyer. A release signed today can extinguish rights you do not yet know you have.
Do not give recorded statements. If an insurance adjuster, a utility representative, or anyone else asks you to provide a recorded statement about your child’s health, your water usage, or your residential history, decline and call a lawyer first. Recorded statements are designed to be used against you, not to help you.
Talk to a toxic tort attorney. Not a generalist. Not a lawyer who handles car accidents and occasionally takes a product case. A toxic tort attorney who understands PFAS chemistry, California’s expert evidence standards, the CERCLA framework, and the specific scientific literature on PFAS carcinogenicity. The consultation is free. The evaluation of whether your specific circumstances warrant further investigation costs you nothing.

Frequently Asked Questions
Can I sue if my child has leukemia and we lived in Los Angeles County?
You may have a claim if your child was diagnosed with acute lymphoblastic leukemia, your family lived in Los Angeles County during pregnancy or early childhood, and your child’s newborn blood spot or other evidence shows elevated PFAS levels. However, having a claim and winning a claim are different things. The study found an association, not proof of causation, and California’s expert evidence standards require a reliable scientific foundation for causation testimony. The only way to know whether your specific circumstances support a viable claim is to have them evaluated by a toxic tort attorney.
Does the study prove PFAS caused my child’s leukemia?
No. The study explicitly states that it “does not prove cause and effect.” It found a statistical association between higher PFAS levels in newborn blood and increased odds of developing leukemia. Association means that the two things occur together more often than chance would predict. Causation means that one thing caused the other. The study is a significant step toward understanding the relationship, but it is not, by itself, proof that PFAS caused any individual child’s cancer. A legal case would need to build on this study with additional scientific evidence, expert testimony, and a specific-causation analysis of your child’s individual exposure and medical history.
How long do I have to file a PFAS leukemia lawsuit in California?
California’s personal injury statute of limitations is two years, but two important rules may extend that deadline. The discovery rule means the clock may not start until you discovered, or reasonably should have discovered, both your child’s injury and its probable toxic cause — which for many families may be the date this study or similar research became known. Minor tolling generally pauses the clock until your child turns 18. The interaction between these rules is fact-specific and requires analysis by an attorney familiar with California toxic tort law. Do not assume you have missed the deadline, and do not assume you have plenty of time. Call for a free evaluation.
What evidence do I need to preserve?
The most important evidence includes: your child’s California newborn screening dried blood spot card (which contains actual measured PFAS levels at birth), complete medical records documenting the leukemia diagnosis and treatment, residential history showing where you lived during pregnancy and early childhood, water utility records for those addresses, and any correspondence from your water provider about water quality or contamination. Do not discard old lease agreements, utility bills, or medical records. If you are unsure whether something is relevant, keep it and ask.
How much is a PFAS childhood leukemia case worth?
The range is extraordinarily wide — from $0 if causation cannot be established to $5,000,000 or more for a case with strong exposure-source tracing, compelling alternative-causation exclusion, and punitive-damages support. The primary value deflator is the Daubert/Kelly-Sargon risk on general and specific causation: if the scientific evidence does not survive expert-evidence challenges, the case may not proceed. Cases that do survive can include medical expenses reaching seven figures, lost earning capacity, non-economic damages unbounded by MICRA, and punitive damages that are uncapped in California toxic tort cases. No attorney can honestly promise a specific dollar amount at the outset of a PFAS leukemia case.
Who can be held responsible for PFAS contamination?
Potentially responsible parties include PFAS chemical manufacturers (who designed and distributed the compounds), industrial dischargers (whose waste streams contaminated water sources), public water utilities (that distributed contaminated water), and manufacturers of PFAS-containing consumer products. CERCLA imposes strict, joint-and-several, and retroactive liability on current and former site owners, operators, generators, and transporters of hazardous substances — and PFOA and PFOS are now designated as CERCLA hazardous substances. Identifying the right defendants for your specific exposure pathway is the threshold work of any claim.
What if my child was born before 2000 or after 2015?
The study specifically analyzed children born in Los Angeles County between 2000 and 2015. If your child was born outside that window, the study’s findings may not directly apply to your case, but they do not foreclose it. PFAS exposure has been ongoing for decades, and other scientific literature may support claims for children born outside the study period. The evaluation depends on your specific facts — when and where your child was born, whether a newborn blood spot exists, and what exposure evidence is available.
Does MICRA limit damages in a toxic tort case?
No. California’s MICRA — the Medical Injury Compensation Reform Act — applies to medical malpractice actions. It does not extend to toxic tort claims. This means non-economic damages in a PFAS cancer case — your child’s pain and suffering, fear of recurrence, loss of quality of life — are not subject to MICRA’s limitations. Additionally, California does not impose a statutory cap on punitive damages in toxic tort cases.
What is the difference between association and causation in these cases?
Association means two things occur together more often than chance predicts — in this case, higher PFAS levels and higher leukemia rates. Causation means one thing actually caused the other. The study found an association. Proving causation in court requires expert testimony establishing that PFAS can cause childhood leukemia (general causation) and that PFAS caused this specific child’s leukemia (specific causation). The defense will argue that association is not enough — and they are right that the law requires more. The question is whether the growing body of scientific evidence, combined with your child’s individual exposure data, can meet that higher standard.
How do I find out if my water was contaminated with PFAS?
Contact your water utility and request water quality reports, including any PFAS testing results. California’s State Water Resources Control Board has established PFAS notification and response levels for drinking water and has issued investigative orders targeting airports, landfills, chrome plating facilities, military bases, and other potential source sites. Public records of PFAS testing in California water systems may be available through the State Water Board. An attorney handling PFAS cases can also subpoena historical testing and operational records from the utilities that served your home.
Should I wait to see if more studies confirm the link before contacting a lawyer?
Waiting is the defense’s strategy, not yours. Every month that passes is a month in which evidence may be lost — water utility records purged, residential history discarded, environmental samples degraded, corporate documents subject to routine retention destruction. The statute of limitations may also be running, depending on how the discovery rule applies to your situation. You do not have to file a lawsuit today. But you should have a free consultation today, so that an attorney can evaluate your timeline, identify what evidence needs to be preserved, and send preservation letters if appropriate. The cost of calling is zero. The cost of waiting may be everything.
If Your Child Has Leukemia and You Lived in Los Angeles County
You did not choose to be here. A peer-reviewed study just told you that the chemicals in your baby’s blood at birth may be connected to the cancer that followed — and now you have to decide what to do with that information. That is not a position any parent should have to occupy.
But you are in it. And the question is not whether the science is perfect — it is not, and no honest lawyer will tell you otherwise. The question is whether your family’s specific facts, combined with the evidence that exists today and the evidence that can still be preserved, support a claim worth pursuing. That question can only be answered by someone who knows the law, knows the science, and knows how to evaluate both together.
Call 1-888-ATTY-911 — that is 1-888-288-9911. Free consultation. No fee unless we win. 24 hours a day, 7 days a week, a live person answers — not a machine, not a call center. We will listen to your child’s story, ask the right questions, and tell you honestly whether your situation warrants further investigation. If it does, the preservation letters go out fast. If it does not, we will tell you that too — because a family in your position deserves the truth, not a sales pitch.
Your child’s newborn blood spot may still exist in a California lab, holding the chemical fingerprint of what was in their body on their first day of life. Your water utility’s records may still show what was in the glass you drank from while you were pregnant. The manufacturer’s own filings may still show what they knew about these chemicals and when they knew it.
All of it is perishable. All of it may matter. And the day you call is the day the clock starts working for your family instead of against them.
