Columbus, Ohio PFAS “Forever Chemicals” in Drinking Water: Health Risks, EPA Rules, and Your Legal Rights
The city of Columbus is ahead of the curve. While municipal water systems across the country still have a few years before federal rules require them to begin removing per- and polyfluoroalkyl substances — the “forever chemicals” known as PFAS — from drinking water, Columbus’s water plants are reportedly already doing it. A Columbus-based company has expanded its operations to help municipal water systems meet the upcoming compliance deadlines, and the city’s own utilities are not treating the deadline as a crisis. They are treating it as a checkpoint they already passed.
That is good news for your tap water today. But it does not close the book on what these chemicals may have already done to the people who drank them, worked with them, or lived near the places that released them — before anyone was testing, before anyone was treating, before anyone was required to tell you what was in the glass.
If you are reading this page, you may be someone who was diagnosed with kidney cancer, thyroid disease, or ulcerative colitis and only recently learned that PFAS exposure has been scientifically linked to those exact conditions. You may have worked at a facility that used PFAS-containing materials for years — a chrome plater, a paper coating plant, a textile mill, a refinery, a fire training facility where PFAS-laden firefighting foam was sprayed for decades. You may live near an industrial site, a military installation, or an airport where aqueous film-forming foam (AFFF) loaded with PFAS was used repeatedly and washed into the ground. Or you may simply be a Columbus resident who heard the word “forever chemicals” on the news and wants to understand what it means for your family’s health and your legal rights.
We are Attorney911 — The Manginello Law Firm, PLLC. We built this page because the intersection of PFAS science, federal regulation, and Ohio toxic tort law is one of the most complex legal subjects in the country, and the person who needs to understand it is usually the person who least expected to be here. What follows is the most complete treatment of PFAS exposure, health risks, federal regulation, and legal rights in Ohio that we know how to write — because the question “can these chemicals cause the disease I have?” is not one a person should have to answer alone.
What Are PFAS “Forever Chemicals” — and Why They Earned the Name
PFAS is a family name. It covers thousands of individual synthetic compounds — perfluoroalkyl and polyfluoroalkyl substances — that share one defining feature: a chain of carbon atoms bonded to fluorine atoms. The carbon-fluorine bond is one of the strongest chemical bonds in organic chemistry. It is the reason these compounds resist heat, repel water, shrug off oil, and survive conditions that destroy almost everything else. It is also the reason they do not break down. Not in sunlight. Not in water. Not in soil. Not in your body.
That is where the name “forever chemicals” comes from. These compounds were engineered to be indestructible — and they are. They accumulate in the environment, in wildlife, and in human blood. They do not metabolize. They do not decay. The human body absorbs them, distributes them through the bloodstream, and excretes them at a rate so slow that the half-life of some PFAS compounds in the human body is measured in years. PFOA’s half-life in human serum is roughly two to four years. PFOS is similar. Some newer compounds may persist even longer. That means if you were exposed to meaningful levels of PFOA a decade ago, a portion of it is still circulating in your blood today.
PFAS were manufactured and used in enormous quantities starting in the 1940s and 1950s. They appear in products most people have touched: nonstick cookware, food packaging, stain-resistant carpeting and upholstery, waterproof clothing, cleaning products, paints, and — in vast quantities — firefighting foam. The military, civilian airports, fire training facilities, and petroleum refineries used AFFF foam containing PFOS and related compounds for decades. When that foam was sprayed — in training exercises, in emergencies, in testing — the PFAS washed into the soil, infiltrated groundwater, and traveled into rivers and reservoirs. The Scioto River and Big Walnut Creek, the two watersheds that feed Columbus’s drinking water system, run through a region with a deep industrial history — manufacturing, aerospace, chemical processing — exactly the kind of industrial activity that produced, used, and sometimes discharged PFAS into the environment.
The chemicals are also in everyday consumer products. As the reporting noted, they are “commonly found in packaging, cookware, carpeting and other everyday items.” That is the source of the background exposure nearly every American carries — trace levels of PFAS detectable in the blood of virtually the entire U.S. population. But background exposure and elevated exposure are two very different things, and the difference between them is where a toxic tort case lives or dies.
EPA’s National Primary Drinking Water Regulation for PFAS
In April 2024, the U.S. Environmental Protection Agency finalized the first-ever federal limits on PFAS in drinking water. The rule — the PFAS National Primary Drinking Water Regulation — set enforceable Maximum Contaminant Levels (MCLs) for six individual PFAS compounds or mixtures. The headline number: PFOA and PFOS, the two most-studied and most-ubiquitous PFAS compounds, were each capped at 4.0 nanograms per liter — which is 4.0 parts per trillion.
Four parts per trillion. That is roughly the equivalent of a single drop of contaminant dispersed across twenty Olympic swimming pools. The EPA set the number there because it is essentially at the limit of what current laboratory technology can reliably detect. The message embedded in that number is blunt: the federal government concluded there is no concentration of PFOA or PFOS in drinking water that it can call safe.
The EPA said exactly that in a companion figure. The Maximum Contaminant Level Goal — the non-enforceable health-based target that sits behind the enforceable MCL — was set at zero for both PFOA and PFOS. Zero. The EPA’s own scientific determination was that no amount of these two compounds in drinking water carries zero risk. The enforceable limit of 4.0 ppt is a compromise with the limits of laboratory detection, not a statement about what is safe to drink.
The 2024 rule also set individual MCLs of 10 parts per trillion for three additional compounds — PFHxS, PFNA, and HFPO-DA (commonly known as GenX) — and established a Hazard Index of 1 as the limit for any mixture of two or more of those compounds plus PFBS. These additional limits matter because they acknowledge that the PFAS problem is not just about two compounds. It is about a family of thousands, and the health risk is cumulative when multiple compounds are present together.
However, the regulatory picture for those additional compounds is in flux. As of mid-2026, the EPA has proposed rescinding the MCLs for PFHxS, PFNA, GenX, and the Hazard Index mixture — while keeping the PFOA and PFOS limits in place. The agency has also proposed extending the compliance deadline for PFOA and PFOS from 2029 to 2031. These are proposed changes, not final rules, and they are subject to public comment and potential litigation. What is certain today is that the 4.0 ppt limit for PFOA and PFOS is the law, and public water systems across Ohio and the nation are working to meet it.
The compliance timeline works in stages. Initial monitoring was required to begin by April 26, 2027. Full compliance with the MCLs was required by April 26, 2029 — the date by which public water systems must have treatment in place to reduce PFAS below the legal limit. If the proposed extension to 2031 is finalized, that date moves back two years. Either way, Columbus’s decision to begin treatment ahead of the deadline means the city is positioned to meet the standard regardless of when the clock runs out.
The Safe Drinking Water Act — the federal statute at 42 U.S.C. § 300f and the provisions that follow — provides the legal framework for these standards. The Ohio EPA enforces them at the state level through its drinking water program, which has been actively sampling public water systems for PFAS contaminants across the state. Ohio has not been passive on this issue. The Ohio EPA’s statewide sampling initiative was one of the earlier state-level efforts to understand the scope of PFAS contamination in public water supplies.
The Health Conditions Science Has Linked to PFAS Exposure
The health effects of PFAS are not theoretical. They have been studied in human populations — including populations in the Ohio River Valley.
The most significant body of epidemiological evidence on PFOA and human disease comes from the C8 Science Panel, a group of independent epidemiologists established as part of a class-action settlement involving PFOA contamination from a chemical plant in Parkersburg, West Virginia. That plant sat on the Ohio River. Its contamination affected drinking water in communities on both sides of the river — West Virginia and Ohio. The panel studied approximately 69,000 people who had been exposed to PFOA through their drinking water, and in 2012 it published a series of “probable link” findings.
The C8 Science Panel found a “probable link” between PFOA exposure and six specific conditions:
- Kidney cancer
- Testicular cancer
- High cholesterol
- Thyroid disease
- Pregnancy-induced hypertension
- Ulcerative colitis
“Probable link” is a legal-epidemiological term of art defined in the settlement agreement. It does not mean “possible” or “maybe.” It means that based on the scientific evidence, the panel concluded that a causal association was more likely than not. Those findings have driven thousands of personal injury claims and remain the scientific spine of much PFAS litigation today.
The article’s own reporting reflects the same health concerns, attributing them to the EPA:
The compounds can suppress the immune system, cause higher cholesterol, decreased fertility, thyroid disease, liver damage, and an increased risk of kidney, testicular and other cancers, according to the U.S. Environment Protection Agency.
Beyond the C8 panel, the world’s leading cancer research authority has weighed in. The International Agency for Research on Cancer (IARC) — part of the World Health Organization — classified PFOA as Group 1: carcinogenic to humans. That is IARC’s highest confidence category, reserved for substances where the evidence of cancer-causing potential in humans is sufficient. PFOA received that designation based on the Working Group’s November 2023 meeting in Lyon, France, with the full monograph published in 2024 as IARC Volume 135. For PFOA, the human evidence was described as “limited” for testicular cancer and renal-cell (kidney) cancer, but the Group 1 classification rested on sufficient evidence in animals combined with strong mechanistic evidence showing how PFOA damages cells. PFOS was classified as Group 2B: possibly carcinogenic to humans — a lower confidence level, but still a formal recognition of cancer concern.
The mechanism of harm is becoming clearer. PFAS compounds bind to serum proteins in the blood — they do not dissolve in fat the way some other persistent pollutants do. Instead, they travel through the bloodstream attached to proteins and concentrate in organs that filter or process blood: the liver, the kidneys, and the thyroid. They are endocrine disruptors, meaning they interfere with hormone signaling. They cause oxidative stress at the cellular level. They modulate the immune system — which is why the EPA lists immune suppression among the documented effects. And because they are not metabolized, the damage they do is cumulative across years of exposure.
The proof problem in any PFAS case is that these conditions — kidney cancer, thyroid disease, ulcerative colitis — all have other causes too. Kidney cancer occurs in people with no PFAS exposure. Thyroid disease is common. Ulcerative colitis has genetic and environmental components that have nothing to do with water contamination. The defense in every PFAS case argues that the plaintiff’s disease was caused by something else: diet, genetics, smoking, age, bad luck.
The counter is exposure. If your serum PFAS levels are elevated — if biomonitoring shows concentrations well above background — and you lived for years in a community with documented drinking water contamination, or worked at a facility where PFAS was used, the dose-response relationship and the C8 panel’s findings become the bridge between exposure and disease. You do not have to prove PFAS is the only cause. You have to prove it was a cause — that it contributed, more likely than not, to the disease you now have.
Columbus, Ohio’s Water System and PFAS: What the Local Picture Shows
Columbus is the state capital and the largest city in Ohio, sitting in Franklin County at the heart of the state. The city operates one of the largest municipal water systems in the Midwest. Its water comes from two main sources: the Scioto River watershed and the Big Walnut Creek watershed. Together, these systems serve more than 1.2 million residents in the greater metropolitan area.
Both watersheds run through central Ohio’s industrial corridor. The region’s manufacturing, aerospace, and chemical processing history means that PFAS detection and remediation is a real public health priority — not because Columbus water is uniquely dangerous, but because the same industrial activity that built central Ohio’s economy is the activity that historically produced, used, and sometimes released PFAS into the environment. The Ohio EPA recognized this when it conducted statewide sampling of public water systems for PFAS contaminants — one of the earlier state-level efforts to map the scope of the problem.
The article’s central point — that Columbus’s municipal water plants are reportedly already implementing PFAS removal measures — is genuinely encouraging. It means the city’s water utilities are not waiting until the federal compliance deadline to act. It means the treatment technology exists, is being deployed, and is working. If you are drinking Columbus tap water today, the system that feeds your faucet is ahead of the regulatory curve.
But the treatment of water today does not erase the years before treatment began. If PFAS was present in the water supply at elevated levels five, ten, or twenty years ago — before anyone was testing for it, before the 2024 federal rule existed, before Columbus began proactive removal — the people who drank that water were exposed. The exposure is in the past. The diseases it may have caused can take years or decades to appear. Kidney cancer, thyroid disease, and the other C8-linked conditions do not necessarily show up the month after exposure. They surface years later — sometimes many years later.
That gap — between the years of exposure and the year of diagnosis — is the gap that toxic tort law was built to address. It is also the gap that makes PFAS cases some of the most medically and legally complex cases in the tort system.
Who May Have a PFAS Toxic Tort Claim in Ohio
Under Ohio law, a toxic tort claim for PFAS-related injury requires proof of three things: exposure to a specific defendant’s PFAS discharge, medical causation linking that exposure to a diagnosed injury, and damages — the financial, physical, and human losses that follow.
Each of those three elements is a separate battle.
Exposure means you have to show that you came into contact with PFAS from a specific, identifiable source. This is not the same as showing that PFAS exists in your water. Virtually everyone has trace levels of PFAS in their blood. The question is whether your exposure was elevated — meaningfully above background — and whether it can be traced to a particular defendant’s conduct. A contaminated water district with documented PFAS levels above the EPA’s 4.0 ppt limit is evidence. Employment records showing you worked at a facility that used PFAS-containing materials for years is evidence. Residence history showing you lived in a community with a known PFAS plume is evidence. Serum biomonitoring — a blood test that measures the actual concentration of PFAS compounds in your serum — is the most direct evidence of all.
Causation means you have to show that the exposure caused your disease. This is where the defense fights hardest. They will argue your kidney cancer was caused by smoking, or hypertension, or obesity, or genetics, or simply the statistical bad luck of a disease that occurs in the general population. The counter lives in the science: the C8 Science Panel’s “probable link” findings, the IARC Group 1 classification for PFOA, the dose-response literature showing that higher exposure correlates with higher disease risk, and your own exposure history — documented, elevated, and temporally connected to your diagnosis.
Damages mean you have to show what the disease cost you. Medical bills. Lost wages. Lost earning capacity — the income you will never earn because the disease shortened your career or ended it. Pain and suffering. The cost of future medical monitoring. If the disease is fatal — and kidney cancer can be — the losses extend to wrongful death: the financial support your family will go without, the companionship and guidance that was taken from them.
If you are considering whether you have a PFAS claim, the intake questions are straightforward: What is your diagnosed medical condition? When were you diagnosed? Where did you live and work during the period of potential exposure? Is there documented PFAS contamination in the water supply that served your home or workplace? Were you occupationally exposed to PFAS-containing materials? Have you had serum PFAS biomonitoring performed?
Those answers — not a lawyer’s opinion — determine whether a PFAS case exists. Our role is to help you find those answers, connect them to the law, and build the case the facts support. We handle toxic tort claims because the people who need this work done are usually people who had no idea they were being exposed until the day a doctor said the word “cancer.”
Ohio Law and PFAS Claims: Statute of Limitations, Comparative Fault, Damage Caps
Ohio’s legal framework for toxic tort claims has several features that shape how a PFAS case must be built and when it must be filed.
The statute of limitations. Ohio’s statute of limitations for personal injury is generally two years from the date of injury or discovery. For PFAS exposure cases — where the disease may not appear until years or decades after the exposure — the discovery rule is the doctrine that can keep a claim alive. Under the discovery rule, the clock does not necessarily start on the day you were exposed to PFAS. It may start on the day you discovered — or, by reasonable diligence, should have discovered — that you had an injury and that PFAS exposure caused it. A kidney cancer diagnosis you received last year, combined with information you only recently learned about PFAS contamination in your former water supply, may mean your clock started recently, not decades ago.
But the discovery rule is not unlimited. Some states impose an outer deadline — a statute of repose — that can cut off a claim even before discovery. Whether Ohio has such a repose provision that applies to toxic tort cases, and how it interacts with the discovery rule, is a question that must be confirmed for the specific facts of your case. The safe approach is to treat the deadline as real and running, and to talk to a lawyer early rather than assuming you have plenty of time.
Comparative negligence. Ohio follows a modified comparative negligence framework. In plain English: if you are partly at fault for your own injury, your recovery is reduced by your share of fault. If your share of fault exceeds a certain threshold, your claim can be barred entirely. In a PFAS case, the defense might argue that you contributed to your own kidney cancer by smoking, by failing to seek medical care earlier, or by choosing to live in a contaminated area after learning about the risk. Every percentage point of fault they pin on you is money subtracted from your recovery — which is exactly why the defense works so hard to assign blame to the plaintiff. The counter is clean exposure documentation and a clear medical timeline that ties the disease to the exposure, not to lifestyle factors.
Damage caps. Ohio has tort reform provisions that include statutory caps on non-economic damages in most personal injury actions. Non-economic damages — pain, suffering, emotional distress, loss of quality of life — are the human costs that no receipt can measure. In Ohio, those damages can be capped, meaning there is a legal ceiling on how much a jury can award for them, even if the jury believes the suffering is worth more. What the caps typically do not touch is the economic stream: medical bills, lost wages, lost earning capacity, future medical care costs. Those are calculated from actual and projected financial losses, and they are generally not subject to the same statutory ceiling. This means that in a PFAS case, rigorous economic proof — a life-care plan, a vocational assessment, a forensic economist’s present-value calculation — is not just helpful. It is the part of the case the caps cannot reach.
CERCLA as a federal overlay. Separate from Ohio’s tort framework, federal law provides its own liability tool. In May 2024, the EPA designated PFOA and PFOS as “hazardous substances” under the Comprehensive Environmental Response, Compensation, and Liability Act — the Superfund law. This designation carries a powerful legal consequence: CERCLA liability is strict (no need to prove the company was careless — only that it owned, ran, made, or transported the contamination), joint and several (any one responsible party can be tapped for the entire cleanup), and retroactive (it reaches conduct from decades before the designation). The only statutory defenses are an act of God, an act of war, or a third party’s act. For a PFAS plaintiff, CERCLA provides a federal liability theory that does not depend on proving negligence at all — only that the defendant released the chemical.
Who Could Be Liable: Tracing PFAS to the Source
In a PFAS case, identifying the responsible party is an investigation, not a guess. The chemicals do not carry a label saying who put them there. But they do leave traces — in water sampling data, in facility records, in the regulatory filings the law requires, and in the geography of contamination plumes.
The categories of potential defendants in PFAS litigation include:
Industrial manufacturers. Companies that produced PFAS compounds or used them in manufacturing processes — chrome plating, textile coating, paper food packaging, semiconductor fabrication, photographic imaging, aerospace components. If a facility in your watershed used PFAS and discharged it into the air, into a river, or onto the ground, that facility is a potential defendant.
Chemical producers. The companies that manufactured PFAS compounds themselves and sold them to downstream users. The corporate history of PFAS manufacturing includes major chemical companies, some of which have already entered into public water system settlements totaling billions of dollars for PFAS remediation. Those settlements — which involve public water utilities, not individual injury claimants — are evidence that the manufacturers knew, or should have known, that their products would contaminate drinking water.
AFFF users. Military bases, civilian airports, fire training facilities, petroleum refineries, and chemical plants that used aqueous film-forming foam for firefighting or training. AFFF was loaded with PFOS and related compounds. When it was sprayed — in training exercises, in emergency responses, in equipment testing — the PFAS washed into soil and groundwater. If you lived near one of these facilities, your drinking water may have been contaminated for years.
The corporate shell game. The company that released the PFAS may not be the company you can sue today. Industrial defendants are often structured in layers: an operating subsidiary that held the license and made the mess, a property company that owns the land, a parent holding company that collected the profits, and perhaps a private-equity sponsor that set the budget. The operating subsidiary may be thinly capitalized — engineered to be judgment-proof. The real assets sit one or two entities up the chain. Identifying the correct corporate defendant — or defendants — requires pulling Secretary of State filings, EPA facility registrations, and corporate ownership records. Naming the wrong entity is how a strong case quietly dies.
The CERCLA designation adds another tool here. Because PFOA and PFOS are now hazardous substances, any facility that released one pound or more of either compound in any 24-hour period was required to report that release to the National Response Center and to state and local emergency authorities. That report — if it was filed — is a paper trail directly connecting a specific facility to a specific release. And because CERCLA liability is retroactive, the designation reaches releases that happened decades ago, long before the 2024 rule.
Separately, the Clean Water Act makes it flatly illegal to discharge pollutants into the nation’s waters without a permit. The permit — an NPDES permit — sets enforceable limits on what a facility may release. When a facility exceeds those limits, it breaks a federal law it agreed to in writing. And the Clean Water Act includes a citizen suit provision that allows private citizens to sue a polluter directly for permit violations, after giving 60 days’ notice to the EPA, the state, and the alleged violator.
There is also the Toxic Substances Control Act. Under TSCA, the EPA requires any person who manufactured or imported PFAS or PFAS-containing articles in any year since January 1, 2011, to report uses, production volumes, disposal, exposures, and known hazards. This means the federal government has been collecting data on who made PFAS, how much they made, where it went, and what they knew about its dangers. That data — if it has been submitted — is a roadmap to defendants and to what they knew.
The Evidence Clock: What Records Exist and How Fast They Disappear
Every piece of evidence in a PFAS case exists on a clock. Some of it is on a long clock. Some of it is already gone.
Water utility testing data. Public water systems are required to test for regulated contaminants and report the results. After the 2024 PFAS rule, systems must begin initial monitoring by April 2027. But some systems — including in Ohio — tested earlier, voluntarily or under state programs. Consumer Confidence Reports, issued annually by water utilities, may contain PFAS results. Ohio EPA’s statewide sampling data is a public record. These records are generally durable — they are government documents retained under public records laws. But the specific sampling event that caught the contamination may have been a one-time test, and the raw sample data may sit in a lab file that is subject to the lab’s own retention schedule.
CERCLA release reports. If a facility released one pound or more of PFOA or PFOS in any 24-hour period after the July 2024 effective date of the hazardous substance designation, it was required to report that release. Those reports go to the National Response Center and to state and local authorities. They are the paper trail of a specific discharge from a specific facility. But the reporting duty only triggers at the one-pound threshold — smaller, chronic seepage may generate no federal report at all.
TSCA manufacturer reports. The TSCA § 8(a)(7) PFAS reporting rule requires manufacturers to compile and submit records going back to 2011 — production volumes, uses, disposal, exposures, and known hazards. These reports, if submitted, are a federal database of who made PFAS and what they knew. The submission window has been moved repeatedly, so at any given moment the database may be incomplete. The absence of a public filing is not proof a company is clean.
Employment records. If you were exposed to PFAS at work, your employment file — dates of employment, job title, work location, safety data sheets for chemicals you handled — is the proof. OSHA’s hazard communication standard requires employers to maintain safety data sheets for hazardous chemicals and to make them accessible to employees. Exposure monitoring records for certain regulated substances must be retained for 30 years. But PFAS is not currently a specifically regulated substance under most OSHA standards, which means the 30-year retention clock may not apply. Employment records can be discarded on the employer’s own retention schedule — often as short as a few years after separation. The longer you wait to request them, the more likely they are to be gone.
Medical records. Your diagnosis, treatment history, lab results, imaging, and pathology reports are the proof of your injury. These are retained by healthcare providers under state and federal medical records laws — typically for several years after the last treatment date. But records do deteriorate, get archived to inaccessible storage, or get purged. If you have a PFAS-related diagnosis, assembling your complete medical record early — while it is still readily accessible — is essential.
Serum PFAS biomonitoring. A blood test that measures the concentration of PFAS compounds in your serum is the most direct evidence of your individual exposure. It is not a standard medical test — you have to seek it out — but it produces a number that connects your body to the chemical. That number, compared against national background levels, can show whether your exposure was elevated. If you are considering a PFAS claim, getting serum biomonitoring done — and done soon — is one of the most important first steps.
The preservation letter — a written demand to every potential defendant and evidence custodian to freeze all relevant records — is the tool that stops the clock. The day you call a lawyer is the day that letter goes out. Before that day, the evidence is dying on its own schedule.
How a PFAS Exposure Case Is Actually Built
A PFAS toxic tort case is not filed overnight. It is built — methodically, layer by layer — from the facts up.
Week one: intake and preservation. The first conversation is about your story: where you lived, where you worked, what you were diagnosed with, and when. The first action is the preservation letter — sent to every entity that may hold evidence of your exposure or the defendant’s conduct. Water utilities, employers, laboratories, the facility itself. The letter orders them not to destroy, alter, or discard any records related to PFAS testing, water quality, chemical use, discharge reports, or your employment. This letter is not a formality. It is the legal mechanism that converts routine record destruction into sanctionable spoliation if the records disappear after notice.
Month one through three: exposure mapping. We reconstruct where your exposure happened. This means pulling water utility data for every address you lived at during the relevant period. It means identifying facilities in your watershed that used or discharged PFAS — from EPA databases, state environmental records, and the TSCA reporting records. It means reviewing your employment history for jobs that involved PFAS-containing materials. If you have not yet had serum biomonitoring, we help you get it. The goal is a documented exposure pathway — a chain that runs from a specific source, through a specific medium (water, air, occupational contact), to your body.
Month three through six: medical documentation and expert retention. We assemble your complete medical record — diagnosis, treatment, pathology, imaging, lab values. We identify the right medical experts: a toxicologist who can testify about the mechanism by which PFAS causes your specific disease; an epidemiologist who can testify about the C8 Science Panel findings and the dose-response literature; a treating physician or specialist who can connect your diagnosis to the exposure. For damages, we retain a life-care planner who builds the cost of your future medical needs — year by year, treatment by treatment — and a forensic economist who reduces that cost stream to present value.
Month six through twelve: defendant identification and filing. With the exposure mapped and the medicine documented, we identify the correct corporate defendants — the entities that released the PFAS, the entities that owned or controlled the facility, and any parent or successor entities whose conduct or assets are reachable. We file the complaint. The statute of limitations clock governs the filing date — and for PFAS cases under Ohio’s discovery rule, the clock may have started when you connected your diagnosis to the exposure, not when the exposure itself happened. Filing on time is not optional.
After filing: discovery and resolution. The discovery phase is where the case is won or lost. We demand the defendant’s internal documents — safety data sheets, discharge monitoring reports, CERCLA filings, TSCA submissions, internal communications about PFAS risks, water testing results. We take depositions — the safety director, the plant manager, the environmental compliance officer — under oath, on the record. The number at the end of the case is built from all of it: the exposure evidence, the medical proof, the expert testimony, the damages calculation, and the defendant’s own documents showing what they knew and when they knew it.
What PFAS Exposure Cases Are Worth
No honest lawyer can tell you what your case is worth without knowing your diagnosis, your exposure history, your treatment costs, your lost income, and the specific defendant’s conduct. What we can tell you is how the number is built — and what Ohio law allows and limits.
Economic damages — the costs you can put on a receipt — are the foundation. Past medical bills: surgery, chemotherapy, immunotherapy, hospitalization, medications, specialist visits. Future medical costs: projected treatment, monitoring, medications, and potential recurrence — built into a life-care plan by a certified planner, priced at current market rates, and reduced to present value by a forensic economist. Lost wages: the income you have already lost to treatment and recovery. Lost earning capacity: the income you will never earn because the disease shortened your career, reduced your ability to work, or ended it. These are the damages Ohio’s caps generally cannot touch — and in a serious PFAS-related cancer case, they can be substantial.
Non-economic damages — the human costs no receipt can measure — are what Ohio’s tort reform caps reach. Pain. Suffering. Emotional distress. Loss of the ability to enjoy the life you had before the diagnosis. The fear of recurrence. The impact on your marriage, your family, your independence. Ohio law allows these damages, but statutory caps may limit the amount a jury can award, regardless of what the jury believes the suffering is worth. The caps are calculated under a formula tied to the economic damages or a statutory floor — and the exact cap that applies to your case depends on the nature of the injury, the year of the claim, and whether any exceptions (such as catastrophic injury provisions) apply. The exact cap must be confirmed for your specific case at the time of filing.
Medical monitoring is a damages category unique to toxic tort cases. If you were exposed to elevated PFAS but have not yet been diagnosed with a linked disease, you may still have a claim for the cost of ongoing medical surveillance — regular blood work, imaging, and specialist visits designed to catch disease early, while it is still treatable. Medical monitoring recognizes that exposure to a carcinogen creates a need for proactive healthcare that unexposed people do not have. Whether Ohio courts recognize medical monitoring as an independent cause of action — or whether it must be sought as part of a broader claim — is a question that depends on the specific facts and the current state of Ohio law.
Punitive damages — damages designed to punish the defendant rather than compensate the plaintiff — may be available in Ohio if the defendant’s conduct was more than negligent. If a company knew its PFAS discharge was contaminating drinking water and concealed that knowledge, or continued to release the chemicals after learning of the danger, that conduct may rise to the level that supports a punitive damages claim. Ohio has its own rules governing the availability and calculation of punitive damages, and those rules must be confirmed for your case.
Wrongful death. If PFAS exposure contributed to a death — kidney cancer is potentially fatal — Ohio’s wrongful death statute allows certain family members to recover for the financial support the deceased would have provided, the services they would have rendered, and the companionship and guidance that was taken from the family. We handle wrongful death claims because the families who need this work are families who already lost someone they should not have lost.
Past results depend on the facts of each case and do not guarantee future outcomes. Every PFAS case is built from its own exposure history, its own medical record, and its own defendant’s conduct. The number — whatever it is — is built from those facts, not from a formula.
The Insurance Adjuster’s Playbook in Toxic Tort Cases
If you have a PFAS-related diagnosis and a potential defendant learns about it — through a water district notice, a community lawsuit, or direct contact — you may hear from an insurance adjuster or a company representative. Here is what they will do, and here is how to counter each play.
Play 1: “Everyone has PFAS in their blood.” The adjuster will point out that PFAS is detectable in virtually every American’s blood. The implication: your exposure is normal, and your disease is just bad luck. The counter: background exposure and elevated exposure are different things. If your serum PFAS levels are well above national medians — if you lived in a community with documented drinking water contamination — your exposure was not “background.” It was elevated by a specific, identifiable source. The dose-response literature shows that higher exposure correlates with higher disease risk. The number in your blood is the number that defeats the “everyone has it” argument.
Play 2: “You cannot prove our chemical caused your cancer.” The adjuster will argue that kidney cancer, thyroid disease, and ulcerative colitis all have many causes, and you cannot prove this specific defendant’s PFAS caused your specific disease. The counter: the C8 Science Panel found a “probable link” between PFOA and kidney cancer. IARC classifies PFOA as Group 1 — carcinogenic to humans. You do not have to prove PFAS is the only cause. You have to prove it was a contributing cause — more likely than not — and the science, combined with your documented exposure, is the bridge.
Play 3: “You waited too long to file.” The adjuster will argue that the statute of limitations has expired because your exposure happened years or decades ago. The counter: Ohio’s discovery rule means the clock may not start until you discovered — or should have discovered — the connection between your exposure and your disease. If you were diagnosed recently and only recently learned about the PFAS contamination in your water supply, your clock may have started recently. But this is not an argument to make yourself — it is a legal question that requires a lawyer’s analysis of your specific timeline.
Play 4: The quick medical monitoring check with a release attached. The adjuster may offer a modest payment — a few thousand dollars for “medical monitoring” — with a release document that, if signed, waives your right to sue for any future injury, including a cancer diagnosis that has not yet appeared. This is the most dangerous play. A check that arrives before your medical results do, with a release printed on the back, is designed to close your case before you know what it is worth. Never sign a release from an insurance company without having a lawyer read it first. The release is permanent. The disease it waives may not be.
Play 5: “Your lifestyle caused your disease.” The adjuster will argue that your kidney cancer was caused by smoking, obesity, hypertension, or occupational exposures unrelated to PFAS. The counter: every potential alternative cause must be examined and, where possible, eliminated. If you did not smoke, if your blood pressure was normal, if you had no other significant occupational carcinogen exposure — the defense’s alternative-cause argument weakens. And under the eggshell-plaintiff doctrine, a defendant takes the victim as found — a pre-existing vulnerability that made you more susceptible to PFAS-related disease does not reduce the defendant’s liability.
What to Do If You Believe PFAS Caused Your Illness
If you have been diagnosed with kidney cancer, testicular cancer, thyroid disease, or ulcerative colitis — and you have reason to believe your drinking water or your workplace exposed you to elevated levels of PFAS — here are the steps that matter most.
Get your medical records together. Pull your diagnosis, your pathology report, your treatment history, your lab results, and your imaging. These documents are the proof of your injury. Request them from every doctor, hospital, and clinic that has treated you for the condition. Medical records can become harder to obtain as years pass — providers archive, purge, or merge. Get them now.
Document your exposure history. Write down every address you lived at during the period of potential exposure — going back as far as you can. Note the water source at each address (municipal water, private well). Note every job you held where you may have come into contact with PFAS-containing materials — chrome plating, textile manufacturing, paper coating, firefighting, military service. Note any facilities near your home — military bases, airports, industrial plants, fire training facilities — that may have used or discharged PFAS.
Request water quality data. Contact your water utility and ask for PFAS testing results for your service area. Check the Ohio EPA’s statewide sampling data — it may include results for your water system. Request Consumer Confidence Reports for the years you lived in the area. If you were on a private well, consider having the well tested — some state programs offer free or low-cost PFAS testing for private wells.
Consider serum PFAS biomonitoring. A blood test that measures PFAS compounds in your serum is the most direct evidence of your individual exposure. Talk to your doctor or a toxicology specialist about whether this test is appropriate for you. The results — compared against national background levels — can show whether your exposure was meaningfully elevated.
Do not sign anything from an insurance company. If you receive a letter, a check, or a release document from an insurance company, a water district, or a facility’s legal representative — do not sign it. Do not cash any check. Do not give a recorded statement. Do not answer questions about your health history over the phone. Everything you say can and will be used to reduce the value of your claim. The friendly voice on the phone is not your friend.
Talk to a lawyer. The statute of limitations is real. The evidence is on a clock. The defendants are already represented. You should be too. The consultation is free. The fee is contingency — we do not get paid unless we win your case. And the conversation costs you nothing but the time it takes to tell your story.

Frequently Asked Questions
What are PFAS “forever chemicals” and why are they called that?
PFAS are a family of thousands of synthetic chemical compounds — perfluoroalkyl and polyfluoroalkyl substances — that share carbon-fluorine bonds, among the strongest bonds in chemistry. They are called “forever chemicals” because those bonds do not break down — not in the environment, not in water, not in the human body. They persist and accumulate for decades.
Can I sue if PFAS in my drinking water caused my cancer?
You may have a claim if you can prove three things: that you were exposed to elevated PFAS from an identifiable source, that the exposure caused your diagnosed disease, and that the exposure resulted in measurable damages. A contaminated water supply with documented PFAS levels above the EPA’s 4.0 ppt limit, combined with a diagnosis of kidney cancer or another C8-linked condition, may support a claim. The specific facts of your exposure, diagnosis, and timeline determine whether a case exists.
How long do I have to file a PFAS lawsuit in Ohio?
Ohio’s statute of limitations for personal injury is generally two years. For PFAS cases, the discovery rule may mean the clock does not start until you discovered — or should have discovered — the connection between your exposure and your disease. A recent cancer diagnosis combined with recently learned information about PFAS contamination in your former water supply may mean your clock started recently. But some states impose an outer deadline (a statute of repose) that can cut off a claim regardless of discovery. You should confirm the deadline that applies to your specific case with a lawyer as soon as possible.
What health conditions are linked to PFAS exposure?
The C8 Science Panel — which studied approximately 69,000 people exposed to PFOA through drinking water in the Ohio River Valley — found a “probable link” between PFOA and six conditions: kidney cancer, testicular cancer, high cholesterol, thyroid disease, pregnancy-induced hypertension, and ulcerative colitis. The EPA also lists immune system suppression, decreased fertility, and liver damage among the documented health effects. IARC, the world’s leading cancer authority, classifies PFOA as Group 1 (carcinogenic to humans).
Is Columbus’s drinking water safe from PFAS?
Based on the reporting that prompted this page, Columbus’s municipal water plants are already implementing PFAS removal measures ahead of the federal compliance deadline. That is genuinely encouraging and means the city is ahead of the regulatory curve. However, treatment today does not address exposure that may have occurred in years past, before treatment was in place and before anyone was required to test for PFAS. If you lived in the Columbus area for years and were diagnosed with a PFAS-linked condition, your exposure may have occurred before the current treatment was operational.
How do I know if I was exposed to PFAS?
Exposure can be documented through several sources: water utility testing data for your service area, Ohio EPA sampling results, employment records showing work at a PFAS-using facility, residence history showing you lived near a known contamination source, and serum PFAS biomonitoring — a blood test that measures the actual concentration of PFAS compounds in your blood. If your serum levels are meaningfully above national background levels, that is direct evidence of elevated exposure.
What is the EPA’s limit for PFAS in drinking water?
The EPA’s 2024 final rule set the Maximum Contaminant Level for PFOA and PFOS at 4.0 parts per trillion each — a number so low it is essentially at the limit of what laboratories can detect. The health-based goal (the MCLG) was set at zero, meaning the EPA found no amount of these compounds in drinking water that carries zero risk. Additional limits were set for PFHxS, PFNA, and GenX at 10 ppt, but those limits are currently proposed for rescission as of mid-2026. The PFOA and PFOS limits remain in effect as current law.
Can I get medical monitoring for PFAS exposure?
If you were exposed to elevated levels of PFAS but have not yet been diagnosed with a linked disease, you may have a claim for the cost of ongoing medical surveillance — regular testing designed to catch disease early while it is still treatable. Whether medical monitoring is available as an independent claim in Ohio depends on the specific facts of your case and the current state of Ohio law. A lawyer can evaluate whether medical monitoring is a viable part of your claim.
Who can be held liable for PFAS contamination?
Potential defendants include industrial facilities that used or discharged PFAS (chrome platers, paper coaters, textile mills, semiconductor fabricators), chemical companies that manufactured PFAS compounds, and facilities that used PFAS-containing firefighting foam (military bases, airports, fire training facilities, refineries). Under CERCLA, liability is strict, joint-and-several, and retroactive — meaning a company can be held responsible for PFAS releases from decades ago without any need to prove negligence. The specific defendant in your case depends on the source of your exposure.
What is my PFAS exposure case worth?
The value of a PFAS case depends on your specific diagnosis, your treatment costs, your lost income and earning capacity, your pain and suffering, and the defendant’s conduct. Economic damages (medical bills, lost wages, future care costs) are generally not subject to Ohio’s statutory damage caps. Non-economic damages (pain, suffering, loss of quality of life) may be subject to caps under Ohio’s tort reform provisions. No honest lawyer can give you a specific dollar figure without reviewing your medical records, your exposure history, and the specific defendant’s conduct. Past results depend on the facts of each case and do not guarantee future outcomes.
Can I still file a claim if I signed a release with the water company or an insurer?
A release you signed — especially one signed before you knew the full extent of your injury — may be challengeable. If you signed a document under pressure, without understanding what you were giving up, or before your disease was diagnosed, the release may not be enforceable. But this is a legal question that requires immediate review of the specific document you signed. Do not assume the release is final until a lawyer has read it. And do not sign any further documents from an insurer without legal review.
Does workers’ compensation cover PFAS-related illness?
If you were exposed to PFAS at work and developed a disease linked to that exposure, you may have a workers’ compensation claim against your employer. But workers’ compensation benefits are capped and do not cover the full range of damages available in a tort claim — particularly pain and suffering. You may also have a separate toxic tort claim against a third party (a chemical manufacturer, a premises owner, a contractor) who is not your employer. The workers’ comp claim and the third-party tort claim are two different lanes, and the third-party lane is where the full measure of damages is available. Both should be evaluated.
