Stella, Wisconsin PFAS Contamination: Your Legal Rights When “Forever Chemicals” Are in Your Well Water
You opened the mail, or you picked up the phone, and a state toxicologist told you to stop drinking your own water — now. Not next week. Not after you finish the dishes. Now. The well your children grew up on, the water you cooked with, made coffee with, bathed in, tested at levels thousands of times above what the federal government says is safe. And nobody was required to tell you. Nobody was required to test. Because your well is private, and private wells are the blind spot in the American drinking water safety system.
We are Attorney911 — The Manginello Law Firm. We handle toxic tort cases. And we are writing this for one person: the homeowner in Stella, Wisconsin — or anywhere in rural Wisconsin, or anywhere in this country — who just learned that the water they trusted for years is loaded with PFAS, the compounds everyone now calls “forever chemicals.” You have questions pouring in faster than answers. Is my family going to be okay? Who did this? Can I make them pay for what they put in my water? Is it too late? We are going to answer every one of those questions, and we are going to do it the way we would if you were sitting across the table from us — which you can be, at no cost, any hour of any day, by calling 1-888-ATTY-911.
What happened in Stella is not an isolated accident. It is part of a national contamination crisis that is still unfolding. A family in a tidy farmhouse surrounded by potato farms in Dunn County accepted a state offer to test their well. The results came back showing PFAS concentrations thousands of times above the federal drinking water limit. Three children had grown up drinking that water. The state told them to stop immediately. And the article that brought this to light frames it against a broader national backdrop — including northwest Georgia, where the carpet industry’s decades of stain-resistant fluorochemical use contaminated water supplies across multiple communities. The same chemicals. The same persistence. The same corporate origin. Different town, different industry, same story: companies made these compounds, knew or should have known they were dangerous, put them into products and waste streams, and let them seep into the groundwater that feeds the wells families depend on.
If your well has tested positive for PFAS — whether in Stella, anywhere in Wisconsin, or anywhere else in this country — this page is for you. Everything below is legal information, not legal advice. Past results depend on the facts of each case and do not guarantee future outcomes. But the information here is real, it is current as of the date we published it, and it is written by trial lawyers who know how these cases are built and fought.
What PFAS “Forever Chemicals” Actually Are — and Why They Earned That Name
PFAS stands for per- and polyfluoroalkyl substances. They are a family of thousands of synthetic chemicals that share one defining feature: a carbon-fluorine bond, which is one of the strongest chemical bonds in organic chemistry. That bond is the reason these compounds are heat-resistant, stain-resistant, water-resistant, and oil-resistant — the properties that made them commercially valuable for decades in everything from nonstick cookware to stain-resistant carpet to firefighting foam. It is also the reason they are called “forever chemicals.” The carbon-fluorine bond does not break down in nature. Not in soil. Not in water. Not in the human body. PFAS persist. They accumulate. They move from soil into groundwater, from groundwater into wells, from wells into the glass of water on your kitchen table, and from that glass into your blood, your organs, and — critically — your children’s developing bodies.
The federal government’s own health scientists recognized this. In April 2024, the EPA finalized the first-ever enforceable federal drinking water limits for PFAS under the Safe Drinking Water Act. The Maximum Contaminant Level — the legal limit — for PFOA and PFOS, the two most-studied PFAS compounds, was set at 4.0 parts per trillion. That is roughly four drops of contamination in an Olympic-sized swimming pool. And the health-based goal — the Maximum Contaminant Level Goal, which is the level at which there is no known or expected health risk — was set at zero.
The EPA finalized health-based Maximum Contaminant Level Goals for PFOA and PFOS at zero — meaning the federal government’s own health scientists concluded there is no amount of these chemicals in drinking water that carries no risk.
Zero. The government’s health goal for these chemicals in your drinking water is zero. When a family’s well tests at thousands of times the legal limit, that is not a margin-of-error situation. That is a family that has been drinking water the government says should contain none of these compounds at all — for years.
The Private Well Regulatory Gap — Why Nobody Tested Your Water Until Now
Here is the fact that makes PFAS contamination of private wells a crisis hiding in plain sight: the Safe Drinking Water Act, the federal law that sets enforceable limits on contaminants in public water systems, does not cover private wells. If your water comes from a municipal system, the EPA requires testing and treatment. If your water comes from a well on your own property — as it does for roughly one-third of Wisconsin’s population, and for millions of households across the United States — the federal government does not require anyone to test it, monitor it, or tell you what is in it.
The family in Stella found out about their contamination because the state of Wisconsin chose to run a voluntary testing program. State scientists mailed an offer. The homeowner accepted “without much thought,” according to the public reporting. Months later, a state toxicologist was on the phone telling them to stop drinking the water immediately. That is how most private well PFAS contamination is discovered — through voluntary state testing, a university study, or a neighbor’s test that prompts the whole street to check. Not through any federal mandate. Not through any required monitoring.
This regulatory gap is not an oversight. It is a deliberate design choice that leaves millions of rural American households dependent on state-level programs that vary wildly in scope, funding, and aggressiveness. Wisconsin has been more proactive than many states — the Wisconsin DNR has implemented state PFAS standards for certain environmental media and has conducted the kind of voluntary well testing that discovered the Stella contamination. But even Wisconsin’s program is voluntary. The decision to test was the family’s. The discovery was almost accidental. And the years of exposure before that discovery — the years the children drank the water, bathed in it, absorbed it — are years no regulator was watching.
The Federal Framework: What the Government Has Done — and What It Means for Your Case
Three federal actions in 2024 transformed the legal landscape for PFAS contamination cases. If your well tested positive, these are the pillars your case stands on.
The EPA Drinking Water Standard (April 2024). The EPA’s National Primary Drinking Water Regulation set enforceable Maximum Contaminant Levels of 4.0 parts per trillion each for PFOA and PFOS. These are the current, binding federal limits. The rule also set limits for additional PFAS compounds — PFHxS, PFNA, and HFPO-DA (GenX) at 10 parts per trillion, plus a Hazard Index for mixtures — but as of mid-2026, the EPA has proposed rescinding those additional limits while keeping the PFOA and PFOS standards in place. What endures, and what matters for your case, is this: the federal government has formally determined that PFOA and PFOS are dangerous in drinking water at any detectable level, has set the legal limit at 4.0 parts per trillion, and has set the health goal at zero. When your well tests at thousands of times that limit, you are looking at a documented, federally recognized health hazard.
The CERCLA Hazardous Substance Designation (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, effective July 8, 2024, means that any entity that releases one pound or more of PFOA or PFOS in any 24-hour period must report that release to the federal government. More importantly for your case, it means that parties responsible for PFAS releases into the environment are subject to CERCLA’s liability framework — which is strict (no need to prove fault), joint and several (any one responsible party can be held liable for the entire cleanup), and retroactive (reaching conduct that occurred before the designation, even decades ago). The defenses under CERCLA are narrow: act of God, act of war, or a third party’s act. “We followed the rules at the time” is not a defense.
The TSCA PFAS Reporting Rule (October 2023). Under the Toxic Substances Control Act, 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 to the agency. This means the federal government has been forcing PFAS manufacturers to hand over what they know about their own products — including what they knew about health risks and environmental persistence — going back more than a decade. The question in any PFAS case is what those disclosures show, and what the companies knew before the public did.
Who Is Legally Responsible for PFAS in Your Well
PFAS contamination cases are not like a car crash where one driver ran a red light. The chain of responsibility often runs from a chemical manufacturer through an industrial user through a waste disposal practice through the soil and into your groundwater. Each link in that chain is a potential defendant, and each carries a different legal theory.
PFAS Chemical Manufacturers. The companies that designed, produced, and marketed PFAS compounds face strict products liability claims for design defect and failure to warn. The core argument: these compounds are unreasonably dangerous by design because their carbon-fluorine bonds prevent environmental degradation, causing irreversible bioaccumulation and persistence in groundwater — a product that cannot be made safe for its intended use. These manufacturers had internal corporate knowledge of health risks and environmental persistence that has been documented in prior litigation and public regulatory records. The public record from PFAS litigation and regulatory proceedings documents corporate knowledge spanning decades. When the IARC — the world’s leading cancer authority — classified PFOA as a Group 1 carcinogen (known to cause cancer in humans) in 2024, it confirmed what internal corporate research had suggested for far longer.
Industrial PFAS Users. Facilities that used PFAS in manufacturing — including the carpet industry in northwest Georgia, which used stain-resistant fluorochemical treatments for decades — face negligence and strict liability claims for abnormally dangerous activities. These facilities discharged or disposed of PFAS-laden waste into the environment, contaminating groundwater that serves private wells. The Dalton, Georgia carpet manufacturing belt in Whitfield County and surrounding counties is one of the most well-documented PFAS hotspots in the country. The same mechanism — industrial use, waste discharge, groundwater contamination, private well exposure — is the mechanism at work in communities across the United States.
Waste Disposal and Biosolids Entities. In rural areas like Stella, surrounded by agricultural operations, a critical potential pathway is biosolids application. Wastewater treatment plants process industrial and municipal waste that contains PFAS. The resulting biosolids — treated sewage sludge — are frequently applied to agricultural land as fertilizer. When it rains, PFAS compounds in the biosolids leach into the soil and migrate into the groundwater that feeds private wells. Entities responsible for PFAS-containing waste disposal or biosolids application near affected wells face claims for negligence, trespass, and nuisance for introducing these compounds into soil and groundwater.
Downstream Product Manufacturers. Companies that used PFAS treatments in their products — stain-resistant treatments, coatings, aqueous film-forming foam (AFFF) used in firefighting training — introduced PFAS into the environment through intended use or foreseeable disposal. These entities face failure-to-warn and design defect claims.
Identifying which of these defendants is responsible for the contamination in a specific well is the work of hydrogeological investigation — contaminant transport modeling, source identification, and groundwater flow analysis. It is the primary value driver in any private well PFAS case. A case with confirmed contamination but no identified source is worth less than a case where hydrogeological tracing connects the PFAS in your well to a specific manufacturer’s product, a specific facility’s discharge, or a specific biosolids application.
Wisconsin Law: Your Rights, the Clock, and the Discovery Rule
Wisconsin recognizes toxic tort claims under multiple legal theories: strict liability, negligence, trespass, and nuisance. Each gives you a different path to hold the responsible parties accountable.
Strict Products Liability. The companies that designed and manufactured PFAS compounds can be held strictly liable for the damage those compounds cause — meaning you do not have to prove they were careless, only that the product was unreasonably dangerous and caused your harm. The design defect argument is uniquely strong for PFAS: these compounds cannot be made safe for their intended use because the very property that makes them commercially valuable — the carbon-fluorine bond that resists degradation — is the property that makes them environmental hazards.
Trespass. PFAS compounds migrated from manufacturing facilities, disposal sites, or biosolids application areas onto your private property and into the groundwater that supplies your well. That is a physical invasion of your property rights by a hazardous substance. Wisconsin recognizes trespass as a cause of action for the intentional invasion of property rights, and the introduction of contaminants onto land through groundwater migration satisfies the elements.
Private Nuisance. The contamination of your well water substantially and unreasonably interferes with your use and enjoyment of your property by rendering your primary drinking water source unsafe for consumption. Your property is less valuable, less usable, and less safe because of what someone else put into the groundwater beneath it.
Negligence. Manufacturers and industrial users failed to exercise reasonable care in testing, marketing, use, and disposal of PFAS compounds despite known or foreseeable risks of groundwater contamination and human exposure. A company that makes a chemical that does not break down, puts it into products and waste streams, and lets it seep into the groundwater feeding families’ wells has failed the most basic duty of care.
Medical Monitoring. Exposure to PFAS at levels thousands of times above federal drinking water limits creates a reasonably certain need for ongoing medical surveillance to detect PFAS-associated diseases — including certain cancers, thyroid dysfunction, and immune disorders — at early, treatable stages. Wisconsin courts recognize medical monitoring as a compensable element of damages in toxic exposure cases. This is particularly critical for children exposed during developmental periods, because PFAS bioaccumulation creates elevated body burdens that persist for years after exposure stops.
The Statute of Limitations and the Discovery Rule. This is the clock that kills cases silently — and the rule that saves them. Wisconsin’s personal injury statute of limitations gives you three years. Wisconsin’s statute for injury to property gives you six years. But the discovery rule changes when that clock starts. For PFAS contamination, the clock generally does not start on the day you were exposed. It starts on the day you discovered — or by reasonable diligence should have discovered — that your water was contaminated and that the contamination caused or could cause your injury.
For the family in Stella, that clock likely started the day the state toxicologist called and told them to stop drinking the water. Not the day the chemicals first entered the well. Not the day the children first drank the water. The day of discovery. For anyone whose well has not yet been tested, the clock may not have started yet — but it will start the day test results come back positive, and waiting to test is waiting to start a clock you cannot stop.
Wisconsin follows a modified comparative negligence standard with a 51% bar — meaning your own share of fault, if any, reduces your recovery but does not bar it unless you are 51% or more at fault. In PFAS well contamination cases, comparative fault is rarely a meaningful defense: you did not manufacture the chemicals, you did not discharge them into the environment, and you did not know they were in your water. Wisconsin does not impose caps on compensatory damages in most personal injury actions. Wisconsin does have statutory limitations on punitive damages — the specific current rule should be confirmed with an attorney at the time of filing.
If your case involves a death from a PFAS-associated disease, Wisconsin’s wrongful death statute provides a separate three-year deadline, and the claim belongs to the surviving family members through a personal representative. You can learn more about wrongful death claims here.
The Medicine: What PFAS Does to the Human Body
PFAS are persistent, bioaccumulative compounds that bind to serum proteins and concentrate in the liver, kidneys, and other organs. They are not metabolized. They do not break down. The human half-life of PFAS — the time it takes for the body to eliminate half of the accumulated burden — is measured in years, not days. For PFOA, the estimated half-life is approximately two to four years. For PFOS, approximately three to five years. For some compounds, even longer. This means that the PFAS your children absorbed over years of drinking contaminated well water will remain in their bodies for years to come — declining slowly, but never quickly enough to undo the exposure that already occurred.
The health effects associated with PFAS exposure have been studied extensively. The C8 Science Panel — an independent group of epidemiologists established as part of a legal settlement between PFAS manufacturer DuPont and contaminated communities in the Ohio River Valley — conducted one of the largest PFAS health studies ever undertaken. The panel found “probable links” between PFOA exposure and six health conditions: kidney cancer, testicular cancer, high cholesterol, thyroid disease, pregnancy-induced hypertension, and ulcerative colitis. Subsequent research has expanded the list of associated conditions to include immune system effects, decreased vaccine response, liver enzyme alterations, and developmental effects in children exposed in utero and through early childhood.
In 2024, the IARC — the International Agency for Research on Cancer, which is the world’s leading authority on cancer-causing substances — classified PFOA as Group 1: carcinogenic to humans. PFOS was classified as Group 2B: possibly carcinogenic to humans. The Group 1 classification for PFOA places it in the same category as asbestos, benzene, and tobacco smoke — substances the world’s cancer science has determined definitely cause cancer in people.
Why children are especially vulnerable. Children drink more water per pound of body weight than adults. Their developing systems are more susceptible to endocrine disruption, immune effects, and developmental harm. PFAS crosses the placenta and is present in breast milk. A child who grew up on a contaminated well absorbed these compounds during the most critical windows of physical and neurological development. The body burden accumulated during those years does not reset when the family switches to bottled water. It declines slowly — over years — while the child continues to grow and develop with that chemical load still present in their blood and organs.
The proof problem the defense exploits. PFAS is in nearly everyone’s blood. The defense in PFAS cases routinely argues that background exposure — from food packaging, consumer products, dust, the general environment — means you cannot trace a plaintiff’s body burden to a specific defendant’s chemical or a specific well’s contamination. The counter is differential exposure: blood serum PFAS levels in a family that drank from a contaminated well at thousands of times the federal limit will be dramatically elevated above background levels. The well water test results, the serum levels, and the proximity to an identified source combine to distinguish household exposure from the ambient background the defense tries to hide behind.
Medical Monitoring: Why It Matters — Especially for Children
Medical monitoring is both a medical necessity and a legal claim. For a family exposed to PFAS at levels thousands of times above the federal limit, the need for ongoing medical surveillance is not speculative. It is a direct, foreseeable consequence of the exposure. The diseases associated with PFAS — kidney cancer, testicular cancer, thyroid disease, immune disorders — are conditions where early detection materially changes outcomes. A patient whose kidney cancer is caught at Stage 1 has a fundamentally different prognosis than one whose cancer is found at Stage 3.
A medical monitoring claim seeks the cost of a court-supervised surveillance program: periodic blood work, thyroid function testing, lipid panels, liver enzyme monitoring, and — where indicated by elevated serum levels or symptom presentation — imaging studies to detect cancers at early, treatable stages. The cost of such a program, projected across the exposure cohort’s expected lifespan, is a recoverable element of damages. For children with developmental exposure, the monitoring period is longer and the surveillance protocol is more intensive — because the body burden is higher and the exposure occurred during critical developmental windows.
Blood serum PFAS testing is the foundation of both medical monitoring and specific causation. A serum test measures the actual concentration of PFAS compounds in a person’s blood — documenting the individual body burden that results from household well water exposure. This data differentiates your family’s exposure from background levels, establishes the dose that connects to the disease risk, and provides the medical baseline against which future monitoring is measured. Critically, PFAS serum levels begin declining the moment exposure stops — slowly, but measurably. Every month that passes between the cessation of exposure and the blood draw is a month in which the peak body burden — the strongest evidence of the exposure dose — is eroding. Early testing captures the highest concentration. Delayed testing understates the exposure. This is not a theoretical concern. It is a clinical and legal reality that makes blood serum testing time-sensitive.
The Evidence Race: What Exists and How Fast It Disappears
PFAS contamination cases live or die on evidence that most families do not know exists and that no one is required to preserve for them. Here is what matters, who holds it, and how fast it can legally vanish.
Well water test results and state agency sampling data. The state’s test results are the baseline document — they establish PFAS concentration levels, identify which specific compounds are present, and fix the timeline of discovery for statute-of-limitations purposes. State agency sampling data has retention limits. Historical records may be purged or archived offsite. Request a complete copy of all testing records for your property immediately, in writing, from the agency that conducted the test. Do not assume the state will keep your file indefinitely.
Blood serum PFAS testing for all exposed household members. This is the most time-sensitive evidence in the case. PFAS serum levels decline slowly after exposure ceases — meaning every month you wait, the peak body burden that documents the true exposure dose is measurably lower. Early testing captures the highest concentration. This data is both medically important and legally powerful: it establishes specific causation, differentiates household exposure from background, and provides the baseline for medical monitoring. Every exposed family member — especially children — should be tested as soon as feasible, through a laboratory that analyzes for the full PFAS panel, not just PFOA and PFOS.
Property records, well construction logs, and aquifer documentation. These establish ownership, well depth, the geological connection to the contaminated aquifer, and baseline property value before contamination was discovered. Historical well construction records and property appraisals may be difficult to locate as time passes. Gather them now — the well drilling report, the property deed, any prior appraisals, and any records of water quality testing conducted before the PFAS discovery.
Corporate documents from PFAS manufacturers and industrial users. Chemical use records, disposal practices, internal health studies, and regulatory communications link specific entities to PFAS releases in the affected area and establish the knowledge element for punitive damages. Corporate document retention policies may destroy historical records. Regulatory filings have varying retention periods. Active litigation holds preserve evidence, but a litigation hold requires a formal preservation demand — which requires an attorney to send it. The TSCA reporting rule requires PFAS manufacturers to compile and retain production, exposure, and hazard records going back to 2011. What those records show — and whether they still exist — depends on how quickly someone demands them.
State environmental agency investigation files and facility inspection reports. These contain source identification studies, sampling data, facility compliance records, and correspondence establishing regulatory notice to potential defendants. Agency file retention varies by record type. Closed investigation files may be archived or subject to disposition schedules. Request the complete file for your area — not just your property, but any PFAS investigation the Wisconsin DNR has conducted in Dunn County and the surrounding region.
The preservation letter — a formal demand that all relevant parties freeze and preserve every document, sample, and data point related to PFAS contamination in your area — is the single most important early step in a PFAS case. It goes out the day you call us. Not the week after. Not after you “think about it.” The day you call. Because every day that passes is a day the defense can argue the records were destroyed under routine retention policy, not in response to a litigation hold. You can reach us for a free consultation at 1-888-ATTY-911, any hour, any day.
What a PFAS Contamination Case Is Worth
Case value in PFAS well contamination cases runs a wide range — from tens of thousands to millions of dollars per plaintiff — driven by the specific facts of exposure, injury, and source identification. We will give you the honest framework, not a promise.
At the lower end — $75,000 to $250,000 per plaintiff. A household with confirmed well contamination but no diagnosed PFAS-related disease may recover the cost of alternative water supply (bottled water, point-of-entry filtration systems, well replacement, or municipal water hookup), property devaluation (the loss in market value from a contaminated well, which can render a property difficult or impossible to sell), and medical monitoring costs for early disease detection. This is the floor — the compensation for having your water poisoned and your property damaged, even if no disease has yet manifested.
At the higher end — into the millions. A plaintiff with a PFAS-associated cancer or serious disease, particularly a child with developmental exposure, could see recoveries in the millions. The national PFAS litigation landscape has produced multi-billion-dollar settlements with major chemical manufacturers — confirming both the severity of the harm and the depth of collectibility. At this level, the damages include past and future medical expenses, lost earning capacity, pain and suffering, emotional distress (the anguish of learning your children consumed contaminated water for years), and — where the manufacturer’s internal knowledge of toxicity and environmental persistence is proven — punitive damages.
What drives value up. Confirmed blood serum PFAS levels dramatically above background. A diagnosed PFAS-associated condition — kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, pregnancy-induced hypertension. Children with developmental exposure. A hydrogeological source identification that traces the contamination in your well to a specific manufacturer, facility, or disposal site. Internal corporate documents showing the manufacturer knew of the health risks and environmental persistence and continued production without adequate warnings.
What drives value down. The primary value deflator in private well PFAS cases is source identification. Contamination without a traceable source is harder to litigate — not impossible, but harder. Blood serum levels that have declined significantly due to delay in testing. A long gap between discovery and legal action that lets evidence disappear. Signing a broad release presented as an “assistance agreement” or “water replacement program” before consulting an attorney.
Wisconsin does not cap compensatory damages in most personal injury actions, which means the full measure of your economic and non-economic losses is recoverable. Wisconsin does have statutory limitations on punitive damages — the current rule should be confirmed at the time of filing. The national PFAS litigation landscape — including the multi-billion-dollar public water system settlements with major chemical manufacturers — confirms that the defendants in these cases have the resources to pay meaningful compensation. The question is not whether the money exists. It is whether your case is built strongly enough to compel it.
The Defense Playbook: What to Expect — and How to Counter It
The companies responsible for manufacturing and using PFAS have been defending these cases for years. They have a playbook. Here are the plays you will see, and the counter to each.
Play 1: The “Assistance Agreement” Trap. Within weeks or months of contamination being discovered, someone — a manufacturer-affiliated testing program, an industrial facility’s “community liaison,” an insurance representative — may approach your family offering free bottled water, a water filtration system, or even a modest payment. The document they ask you to sign will be called an “assistance agreement,” a “water replacement program,” or a “goodwill arrangement.” Buried in the fine print will be a broad liability release: by accepting the water or the payment, you agree not to sue. The counter: do not sign anything from any industrial facility, manufacturer-affiliated program, or insurance representative without having an attorney review it first. A legitimate offer of assistance does not require you to surrender your legal rights. If it does, it is not assistance. It is a settlement designed to cost the company less than what your case is worth.
Play 2: The “Ubiquitous Background Exposure” Defense. The defense will argue that PFAS is everywhere — in food packaging, consumer products, household dust, the general environment — and that your family’s body burden cannot be traced to their specific product or facility. The counter: blood serum PFAS levels in a family that drank from a well testing at thousands of times the federal limit will be dramatically elevated above the national background level. The well water test results, the serum levels, and the proximity to an identified source combine to distinguish household exposure from ambient background. The defense cannot explain a serum level five or ten times the national average by pointing at pizza boxes.
Play 3: The “No Source-to-Well Tracing” Argument. The defense will argue that you cannot prove their specific product or facility caused the specific contamination in your specific well. The counter: hydrogeological contaminant transport modeling — performed by a qualified expert witness — traces PFAS migration from a source (a manufacturing facility, a disposal site, a biosolids application area) through the groundwater system to your well. Groundwater flows along predictable paths determined by geology, gradient, and aquifer characteristics. PFAS contamination leaves a chemical fingerprint — the specific compounds present, their ratios, and their concentrations — that can be matched between source and well. This is not speculation. It is environmental forensics.
Play 4: The Delay and Stall. The defense will extend every deadline, contest every document request, and run the clock toward the statute of limitations while hoping you lose momentum, lose evidence, or lose interest. The counter: a preservation letter sent immediately, aggressive discovery demands, and a litigation team that understands the evidence-decay timeline and does not let the defense run out the clock. Lupe Peña, our associate attorney, spent years inside a national insurance-defense firm — he sat in the rooms where adjusters and their software decided how to deny, delay, and devalue claims. He knows these tactics from the inside. Now he uses that knowledge for injured clients. You can read more about him here.
Play 5: The “We Followed the Rules” Defense. The defense will argue that PFAS production and use was legal at the time, that no regulations prohibited their discharge, and that they cannot be held liable for conduct that was permissible when it occurred. The counter: CERCLA liability is strict and retroactive — it reaches conduct that occurred before the hazardous substance designation, even decades before. “We followed the rules at the time” is not a CERCLA defense. The only statutory defenses are act of God, act of war, or a third party’s act. A company that manufactured and released PFAS into the environment cannot hide behind the absence of a regulation that did not yet exist — especially when their own internal research documented the risks.
How a PFAS Case Is Actually Built
Here is the chronological walk — from the day you call to the day a number is on the table.
Week one: preservation. The day you contact us, the preservation letter goes out — to every potential defendant, every relevant state agency, and every third-party data holder. That letter demands the freeze of well water test data, state agency investigation files, corporate manufacturing and disposal records, biosolids application records, and any internal health studies or communications related to PFAS. The letter creates a litigation hold: once it is received, destruction of relevant documents is not routine retention — it is spoliation, and a court can impose sanctions, including an adverse-inference instruction telling the jury to assume the destroyed evidence was as bad as the plaintiff says.
Weeks two through four: evidence gathering. We obtain complete copies of all state testing records for your property and the surrounding area. We pull Wisconsin DNR investigation files for Dunn County and neighboring jurisdictions. We identify potential sources — manufacturing facilities, industrial users, wastewater treatment plants, biosolids application sites, fire training areas — and begin the hydrogeological investigation that will connect the contamination in your well to a specific defendant’s conduct. We arrange blood serum PFAS testing for all exposed household members through a qualified laboratory, capturing peak body burden before levels begin their slow decline.
Months one through three: expert retention. A PFAS case requires a team of expert witnesses. A board-certified toxicologist establishes general causation — the scientific link between PFAS exposure and specific health conditions. A hydrogeologist performs contaminant transport modeling and source identification — tracing the PFAS in your well to a specific facility, disposal site, or application area. An epidemiologist establishes specific causation — linking your individual PFAS body burden to any diagnosed conditions. A life-care planner builds the future-care cost stream, and a forensic economist reduces it to present value.
Months three through twelve: discovery. The corporate documents come out. Internal health studies. Marketing decisions. Waste disposal practices. Regulatory communications. The TSCA reporting filings. The internal memos that show what the manufacturers knew about PFAS toxicity and environmental persistence — and when they knew it. These documents drive both liability and punitive damages. The depositions follow, where corporate representatives explain their choices under oath.
Year one and beyond: resolution. PFAS cases are complex, long-duration litigation. The national PFAS litigation landscape has produced multi-billion-dollar settlements, and mediation in these cases leverages the substantial public record of prior settlements to establish value benchmarks. Cases may evaluate consolidation through multidistrict litigation or state court mass joinder, given the shared factual questions across geographically dispersed plaintiff populations. The timeline is measured in years, not months — but the evidence preserved in the first weeks is what makes the resolution possible.
The First 72 Hours: What to Do Right Now
If your well has tested positive for PFAS — or if you have reason to believe it may be contaminated — here is what to do, in order, starting now.
Hour 1: Stop drinking the water. This is not a legal instruction. It is a medical one. If a state toxicologist or health official has told you to stop, stop. Switch to bottled water for all consumption — drinking, cooking, making ice, preparing infant formula. If you cannot afford bottled water, contact your local health department about emergency water supply assistance. Do not boil the water — boiling concentrates PFAS, it does not remove them.
Hour 2: Document everything. Save every document related to the testing — the state’s offer letter, the test results, any correspondence with the agency, the phone call where you were told to stop drinking the water. Write down the date and time of that call, the name of the person who told you, and exactly what they said. Photograph the well, the testing equipment if any was left on site, and any visible conditions around the property. Do not dispose of any water samples.
Hour 24: Request your complete file. Contact the state agency that conducted the testing and request a complete copy of all records related to your property — not just the summary results, but the full analytical report, the chain of custody, and any historical sampling data for your area. Put the request in writing. Keep a copy.
Hour 48: Arrange blood serum testing. Contact a laboratory that performs PFAS blood serum analysis and arrange testing for every exposed household member. Ask whether the lab analyzes for the full PFAS panel or only PFOA and PFOS. The full panel is preferred — compounds like PFHxS, PFNA, and PFBS may be present in your water and contribute to your total body burden. If you need help finding a qualified laboratory, call us. We maintain relationships with laboratories that perform this analysis.
Hour 72: Do not sign anything. If anyone — a manufacturer representative, an industrial facility, an insurance adjuster, a “community liaison” — has offered you water, money, filtration, or any other form of assistance and asked you to sign a document, do not sign it. Call us first. A document that requires you to release your legal rights in exchange for a few cases of bottled water is not a favor. It is a trap designed to close your case before it opens.
Then: Call us. The preservation letter goes out the day you call. The evidence freeze starts the day you call. The clock on building your case starts the day you call. The consultation is free. The call costs nothing. We do not get paid unless we win your case. 1-888-ATTY-911. Any hour. Any day.

Frequently Asked Questions
Can I sue if my private well is contaminated with PFAS?
Yes. Private well owners whose water has been contaminated with PFAS by the actions of chemical manufacturers, industrial users, or waste disposal entities have legal claims under multiple theories: strict products liability, negligence, trespass, private nuisance, and medical monitoring. The fact that private wells are not regulated by the Safe Drinking Water Act does not mean you have no legal rights — it means the government did not protect you, but the civil justice system can still hold the responsible parties accountable. The strength of your case depends on confirming the contamination through testing, documenting your exposure through blood serum analysis, and — through hydrogeological investigation — tracing the contamination to its source.
How long do I have to file a PFAS lawsuit in Wisconsin?
Wisconsin’s personal injury statute of limitations gives you three years, and the property damage statute gives you six years. But the discovery rule changes when that clock starts. For PFAS contamination, the clock generally starts when you discover — or reasonably should have discovered — that your water was contaminated and that the contamination could cause harm. For the family in Stella, that clock likely started the day the state toxicologist called. For someone whose well has not yet been tested, the clock may not have started yet. But once test results come back positive, the clock is running — and every month of delay is a month of evidence that is disappearing. Do not wait to find out if you have time. Find out now.
What health problems are linked to PFAS exposure?
The C8 Science Panel — an independent epidemiological research group established through a legal settlement — found probable links between PFOA exposure and six conditions: kidney cancer, testicular cancer, high cholesterol, thyroid disease, pregnancy-induced hypertension, and ulcerative colitis. Additional research has associated PFAS exposure with immune system effects, decreased vaccine response, liver enzyme changes, and developmental effects in children. In 2024, the IARC classified PFOA as a Group 1 carcinogen — known to cause cancer in humans — and PFOS as Group 2B, possibly carcinogenic. The health effects depend on the level of exposure, the duration, the specific compounds involved, and individual susceptibility. Blood serum testing documents your individual body burden and helps assess your specific risk profile.
How much is a PFAS contamination case worth?
Case value ranges widely — from $75,000 to $250,000 per plaintiff at the lower end (confirmed contamination without diagnosed disease, covering property damage, alternative water costs, and medical monitoring) to millions of dollars at the higher end (PFAS-associated cancer or serious disease, especially in children with developmental exposure). What drives value: confirmed serum levels above background, a diagnosed PFAS-associated condition, hydrogeological source identification linking the contamination to a specific defendant, and internal corporate documents showing the manufacturer knew of the risks. What reduces value: inability to trace the contamination to a specific source, delayed blood serum testing that understates the exposure dose, and — critically — signing a liability release before consulting an attorney. Wisconsin does not cap compensatory damages in most personal injury actions.
Who is responsible for PFAS in my well water?
PFAS contamination typically involves a chain of responsibility: the chemical manufacturers who designed and produced the compounds (strict products liability for design defect and failure to warn), the industrial users who discharged PFAS-laden waste into the environment (negligence and strict liability for abnormally dangerous activities), the entities that applied PFAS-containing biosolids to agricultural land near your well (negligence, trespass, and nuisance), and downstream product manufacturers whose products introduced PFAS into the environment through intended use or foreseeable disposal. In rural areas like Stella, surrounded by agricultural operations, biosolids application is a recognized PFAS pathway — wastewater treatment plants process industrial and municipal waste containing PFAS, and the resulting biosolids applied to farmland can leach PFAS into the groundwater feeding private wells. Identifying the specific responsible party requires hydrogeological investigation.
What should I do if my well water tested positive for PFAS?
Stop drinking the water immediately. Save every document related to the testing. Request your complete file from the testing agency in writing. Arrange blood serum PFAS testing for all exposed household members through a qualified laboratory. Do not sign any document presented by a manufacturer, industrial facility, or insurance representative without legal review. Do not dispose of any water samples. Photograph your well and property conditions. Write down the timeline of when you learned about the contamination and who told you. Then call an attorney who handles toxic tort cases — the preservation letter that freezes evidence needs to go out immediately, because the records that prove your case are on retention clocks that do not wait for you.
Should I get my blood tested for PFAS?
Yes — and the sooner the better. Blood serum PFAS testing documents your individual body burden — the actual concentration of PFAS compounds in your blood resulting from your household well water exposure. This data is both medically important (it tells your doctor what you were exposed to and at what level, informing your medical monitoring protocol) and legally powerful (it differentiates your exposure from background levels and establishes the dose that connects to disease risk). Critically, PFAS serum levels decline slowly after exposure stops — meaning every month you wait, the peak body burden that best documents your exposure dose is measurably lower. Early testing captures the strongest evidence. Delayed testing understates the exposure. This is a time-sensitive medical and legal step.
Can I sign a water replacement agreement from the company?
Not without having an attorney review it first. Documents presented as “assistance agreements,” “water replacement programs,” or “goodwill arrangements” frequently contain broad liability releases — by accepting bottled water, a filtration system, or a modest payment, you may be agreeing not to sue the company for the contamination. A legitimate offer of emergency water assistance does not require you to surrender your legal rights. If the document asks you to release, waive, or discharge any claims, it is not assistance — it is a settlement designed to close your case for a fraction of what it is worth. Call us before you sign anything. The review is free. The cost of signing without review could be your entire case.
What if my children drank the contaminated water for years?
This is the cruelest aspect of PFAS contamination: children are the most vulnerable. They drink more water per pound of body weight than adults. Their developing systems are more susceptible to endocrine disruption, immune effects, and developmental harm. PFAS crosses the placenta and is present in breast milk. A child who grew up on a contaminated well absorbed these compounds during the most critical windows of physical and neurological development, and the body burden accumulated during those years will persist for years — declining slowly, but never quickly enough to undo the exposure. Children who drank contaminated well water for years have the strongest medical monitoring claims, the most compelling damages narratives, and — if a PFAS-associated disease develops — the highest case values. Blood serum testing for exposed children is urgent: their peak body burden is the strongest evidence of their developmental exposure, and it is declining from the day the family stopped drinking the well water.
How long does a PFAS lawsuit take?
PFAS contamination cases are complex, long-duration litigation — measured in years, not months. The preservation letter goes out immediately, but the hydrogeological investigation, expert retention, discovery, depositions, and resolution process unfold over a longer arc. Cases that consolidate into multidistrict litigation or state court mass joinder may follow a bellwether case timeline where test cases go to trial first and settlement frameworks follow. The national PFAS litigation landscape has produced multi-billion-dollar settlements, but those settlements took years to reach. What you can control is the evidence: the documents preserved in the first weeks, the blood serum levels captured in the first months, and the hydrogeological work that connects your contamination to its source. The timeline is long. The evidence window is short. That is why the call needs to happen now.
Why Our Firm

Lupe Peña is our associate attorney. He is a former insurance-defense attorney who spent years inside a national defense firm — the rooms where adjusters and their software decided how to deny, delay, and devalue claims exactly like yours. He knows how the other side values your case, which doctors they pick for independent medical exams, and how surveillance and social-media monitoring are used against injured people. He is fluent in Spanish and conducts full client consultations in Spanish without an interpreter. A third-generation Texan with roots to the King Ranch, he now sits on your side of the table.

The firm has recovered more than $50 million for clients. Past results depend on the facts of each case and do not guarantee future outcomes. What we can tell you is this: the knowledge in this page — the regulatory framework, the evidence clocks, the defense playbook, the medicine — is the knowledge we bring to every case. The preservation letter that goes out the day you call is the same letter that would go out for any family in your situation. The difference between a case that recovers meaningful compensation and a case that quietly disappears is almost always the speed and quality of the evidence preservation. That is what we do. That is what we are offering you.
The Call
The family in Stella did the right thing. They accepted the state’s offer to test their well. They followed the toxicologist’s instruction to stop drinking the water. What happened to them is not their fault. It is the fault of the companies that designed chemicals that do not break down, put them into products and waste streams, and let them seep into the groundwater that feeds families’ wells. The law provides pathways to hold those companies accountable — for the property damage, for the medical monitoring, for the anguish of discovering your children grew up drinking contaminated water, and for the diseases that exposure may cause in the years to come.
But the law has a clock. And the evidence has a shorter clock. The blood serum levels that document your family’s exposure are declining from the day you stopped drinking the water. The corporate documents that prove what the manufacturers knew are on retention schedules that do not wait for you. The state agency files that establish the timeline of discovery are subject to disposition schedules. Everything that makes your case strong is also everything that is disappearing.
