Your Drinking Water Has “Forever Chemicals” in It — What That Means for Your Family in Southeast Louisiana
You just found out that the water coming out of your tap — the water you have been drinking, cooking with, making baby formula with, showering in — contains chemicals that do not break down. Not in the environment. Not in your body. A residential water quality study tested 107 homes across seven Southeast Louisiana parishes and found PFAS in 105 of them. Perfluorooctanoic acid appeared in 97.2 percent of the samples. Perfluorooctane sulfonic acid showed up in 72.9 percent. Arsenic was in 70 percent. Lead was in 67 percent. Every single sample taken during low Mississippi River water levels exceeded the EPA’s recommended salt thresholds. One sample in Plaquemines Parish measured 43 percent above the pending federal limit for PFAS.
If you live in St. James, St. John the Baptist, St. Charles, Jefferson, Orleans, St. Bernard, or Plaquemines Parish, this is your kitchen table right now. You are looking at a glass of water and wondering whether it is safe to drink. You are wondering what this means for your children, whose developing immune systems the science says are especially vulnerable. You are wondering whether anyone can be held accountable for putting these chemicals in your water, or whether the rollback of federal protections means the companies that contaminated it will simply walk away.
We are going to answer every one of those questions on this page. Not in generalities — in the specific law of Louisiana, the specific science of PFAS, the specific geography of the Mississippi River corridor, and the specific evidence that is disappearing on a clock you cannot see. This is what we do. We are Attorney911 — The Manginello Law Firm, PLLC — and we handle toxic tort cases for families who have been poisoned by someone else’s decisions.
What the Study Found — and What It Means for Your Family
The Southeast Louisiana Residential Water Quality Study was conducted to inform residents about the long-term health risk of low-level exposures to lead, arsenic, and PFAS — even when most detections fall below enforceable limits. That last phrase is the key to understanding why this is a legal issue and not just a public health notice. The study found that while most of the PFAS and heavy metal detections were below the levels federal health officials currently deem actionable, there is consensus among physicians that no amount of PFAS exposure is safe.
Let us walk you through the numbers that matter.
Out of 107 homes tested across the seven parishes, 105 had at least one detectable PFAS compound. The study tested for 18 different PFAS chemicals and found seven of them at least once. Two dominated: PFOA appeared in 97.2 percent of tap water samples, and PFOS appeared in 72.9 percent. These are the two compounds the federal government regulated first, the two that the International Agency for Research on Cancer has classified — PFOA as a known human carcinogen and PFOS as a possible carcinogen. They are in nearly every glass of water coming out of Southeast Louisiana taps.
Arsenic showed up in 70 percent of samples. Lead in 67 percent. Salt levels exceeded EPA recommended thresholds for drinking water quality in 100 percent of samples taken during low water levels on the Mississippi River. And one Plaquemines Parish sample measured 43 percent above the pending federal PFAS limit — a concrete, above-limit detection that provides a regulatory benchmark for an above-limit exposure claim.
The study found no meaningful difference between parishes that draw drinking water from aquifers — St. James and St. John the Baptist — and those that pull from the Mississippi River. The contamination is everywhere in the corridor. It does not respect parish lines or water source.
But it does respect race and income in one telling respect. The study documented sharp disparities in heavy metal exposure: Black and lower-income households recorded the highest concentrations of arsenic and lead. Study participants with a high school education or less, and those earning under $25,000 a year, recorded the highest peaks in heavy metal exposure. PFAS, by contrast, appeared more uniformly across all demographic groups — which makes sense, because PFAS dissolves in water and travels through municipal systems regardless of who is drinking it at the other end.
“Something that makes PFAS unusual, compared to the vast majority of chemicals that we toxicologists study, is that PFAS dissolve in water. Now PFAS also contaminate the drinking water of millions of Americans.”
That statement came from a Boston University School of Public Health environmental health professor and toxicologist who assisted in the study. It tells you why this contamination is different from every other chemical exposure a Louisiana resident might face. Most toxic chemicals that enter water either settle into sediment, evaporate, or break down over time. PFAS do none of those things. They dissolve. They travel. They reach every tap. And once they enter your body, they stay — measured in years, not days.
What PFAS Does Inside Your Body
PFAS are per- and polyfluoroalkyl substances — a family of more than 12,000 synthetic chemicals used since the 1940s in nonstick cookware, cleaning products, carpets, waterproof clothing, food packaging, and firefighting foam. They are called “forever chemicals” because the carbon-fluorine bonds that make them useful are among the strongest in organic chemistry. No natural process breaks them down. They persist in the environment indefinitely, and they persist in your body for years.
Here is the mechanism, in plain language. When you drink water containing PFAS, the compounds pass through your intestinal wall and enter your bloodstream. Unlike most chemicals, which your liver and kidneys process and excrete within hours or days, PFAS bind to proteins in your blood — particularly albumin — and circulate through your body repeatedly. They concentrate in the liver, kidneys, and blood. Your body cannot metabolize them. It cannot break them apart. It can only excrete them slowly, and the half-life of PFOA in human serum is approximately two to four years. For PFOS, it is approximately three to five years. That means if you stopped drinking contaminated water today, half the PFAS in your blood would still be there in three years. A quarter would still be there in six years.
The health conditions the scientific literature has linked to PFAS exposure include:
High cholesterol. PFAS interfere with how your body processes lipids. The C8 Science Panel — a team of independent epidemiologists who studied nearly 70,000 people exposed to PFOA-contaminated drinking water in West Virginia and Ohio — found a “probable link” between PFOA and high cholesterol. This is one of the most consistently reproduced findings in PFAS epidemiology.
Liver damage. PFAS concentrate in the liver and disrupt normal liver enzyme function. Studies have documented elevated liver enzymes in exposed populations, indicating cellular stress and potential long-term liver disease.
Thyroid disease. PFAS interfere with thyroid hormone production and regulation. The C8 Science Panel found a probable link between PFOA and thyroid disease.
Reduced vaccine response in children. This is the finding that should make every parent in these seven parishes pay attention. PFAS exposure has been associated with reduced immune response to childhood vaccinations — meaning children exposed to PFAS may produce fewer antibodies in response to vaccines, leaving them less protected against the very diseases the vaccines are designed to prevent. The study’s lead policy coordinator noted that while the testing provides just a snapshot, “these small amounts of exposures can add up, which is why ongoing monitoring and mitigation is important.”
Kidney cancer and testicular cancer. The C8 Science Panel found a probable link between PFOA and both kidney cancer and testicular cancer. IARC, the world’s leading cancer authority, classified PFOA as a Group 1 known human carcinogen in 2024. PFOS was classified as Group 2B, possibly carcinogenic to humans.
Pregnancy-induced hypertension and ulcerative colitis. Both were found to have a probable link to PFOA exposure by the C8 Science Panel.
The article reporting this study noted that PFAS consumption has been linked to high cholesterol, liver damage, increased risk of thyroid disease, and reduced vaccine response in children. The broader scientific literature extends that list to include specific cancers and pregnancy complications. The federal government’s own Maximum Contaminant Level Goal for PFOA and PFOS in drinking water is zero — meaning EPA found no threshold below which there is no known health risk. The legal limit was set at four parts per trillion not because four parts per trillion is safe, but because four parts per trillion is the lowest level current testing methods can reliably detect.
That is the gap the defense will exploit: most of the detections in this study fall below enforceable federal limits. But the enforceable limit is not a safety threshold. It is a detection threshold. The health goal is zero. The medical consensus is that no level is safe. That distinction is the heart of a PFAS medical monitoring claim.
Who Is Responsible for the Contamination
This is the most complex question in any PFAS water contamination case, and we are going to be honest with you about why. The study found contamination. It did not name a specific source defendant. Identifying who put the PFAS, lead, and arsenic into your water requires environmental forensics — a scientific investigation that matches the chemical fingerprint of the contamination in your tap water to the known discharges of industrial facilities, military installations, and product manufacturers along the Mississippi River corridor.
Here are the categories of defendants that environmental forensics can identify:
PFAS chemical manufacturers. Companies that designed, manufactured, and distributed PFAS compounds — including 3M, DuPont, Chemours, and successor entities — knew or should have known that these chemicals were persistent, bioaccumulative, and harmful to human health. Products liability claims against these manufacturers assert design defect (the chemicals were unreasonably dangerous by design because they cannot break down) and failure to warn (the manufacturers did not alert end-users, water systems, or regulators of the health risks). The national AFFF and PFAS multidistrict litigation provides a roadmap for expert selection, causation methodology, and regulatory history development in these cases.
Industrial dischargers along the Mississippi River corridor. The seven-parish study area spans the heavily industrialized Mississippi River corridor from St. James and St. John the Baptist Parishes — long identified as part of Louisiana’s “Cancer Alley,” dense with petrochemical plants, refineries, and chemical manufacturing facilities — through the New Orleans metropolitan area and south to Plaquemines Parish at the river’s mouth. Industrial facilities that discharged PFAS, heavy metals, or other contaminants into source waters — whether through permitted NPDES discharges or unpermitted releases — are potential defendants. The federal Clean Water Act makes the discharge of any pollutant without a permit unlawful, and the permit itself is a written promise capping exactly what a company may release. NPDES discharge monitoring reports are the polluter’s own admissions of what it released.
Aqueous film-forming foam (AFFF) manufacturers and users. Firefighting foam is one of the most concentrated sources of PFAS in the environment. Military installations, airports, and industrial facilities that used AFFF for training or emergency response may have contaminated groundwater and surface water. The Department of Defense has been destroying certain legacy foam stockpiles — which means the records of what was used, where, and when are on a preservation clock. AFFF use and storage records from nearby installations may identify a concentrated point source.
Municipal and parish water utilities. Water system operators — including the Sewerage and Water Board of New Orleans, which operates one of the oldest urban water systems in the nation, and parish-level systems across the corridor — have a duty arising from their public water system operator status under the Safe Drinking Water Act and Louisiana environmental law. Potential claims include failure to monitor for PFAS, failure to treat or filter source water to remove contaminants, and failure to warn residents about the presence of PFAS, lead, and arsenic in delivered drinking water. Consumer Confidence Reports — the annual water quality reports utilities are required to send to customers — and historical testing data will show whether the utility knew or should have known about the contamination.
The Louisiana Department of Environmental Quality. LDEQ administers and enforces drinking water standards at the state level under delegated authority from the Safe Drinking Water Act, with parallel obligations under the Louisiana Environmental Quality Act. Potential claims related to insufficient monitoring, enforcement, or permitting practices would face governmental immunity and notice-of-claim requirements under the Louisiana Tort Claims Act. A licensed Louisiana attorney must confirm the current LTCA notice deadline and whether it applies to your specific claims.
The critical deflator on case value — and we are going to be straight with you about this — is that no specific industrial source defendant is identified in the study. The majority of detections fall below enforceable federal limits. Causation attribution is the primary value gate. Without an identified source through environmental forensics, individual case value is highly speculative. But the forensics can be done. Hydrogeologists and environmental chemists can perform source attribution analysis correlating PFAS compound signatures in tap water with known industrial dischargers, AFFF use sites, and chemical manufacturing facilities along the corridor. That investigation is the foundation of the case.
Louisiana Law: Your Rights and the Clock
Louisiana operates under a civil-law system that is different from every other state in the country. In Louisiana, what most states call “torts” are called “delictual obligations.” What most states call a “statute of limitations” is called “prescription.” The rules are similar in function but distinct in origin and terminology, and if your case is filed by someone who does not understand the difference, the mistake can be fatal.
Here is the rule that matters most: Louisiana’s prescriptive period for delictual actions generally runs one year from the date the damage is sustained or discovered. That is a short clock — shorter than most states. But for toxic tort cases involving latent injuries — diseases that take years or decades to develop after exposure — Louisiana applies a prescription-discovery analysis that can extend the filing window. The clock does not necessarily start on the day you were exposed to PFAS. It may start on the day you discovered, or should have discovered through reasonable diligence, that your water was contaminated and that the contamination caused or could cause your injury.
For many residents in these seven parishes, the publication of this water quality study may be the triggering event — the moment they discovered their drinking water contained PFAS, lead, and arsenic. If you have been diagnosed with a PFAS-linked condition — thyroid disease, high cholesterol, liver enzyme abnormalities — the prescription clock may run from the date you connected your diagnosis to the water exposure, not from the date of diagnosis alone.
Louisiana follows a comparative fault regime. If a plaintiff is allocated a percentage of fault, their recovery is reduced by that percentage but is not barred entirely. In PFAS water contamination cases, the defense may try to allocate fault to the resident for aging private plumbing that contributed to lead exposure — but the environmental justice finding that Black and lower-income households bore the highest heavy metal concentrations is a factual counter to any attempt to blame residents for infrastructure they do not control.
The Louisiana Environmental Quality Act provides the state’s regulatory framework for water quality and pollutant discharges, administered through LDEQ. Violations of permit conditions or water-quality standards may support negligence-per-se theories — meaning the violation of the regulation itself can serve as proof of negligence, not just evidence of it. A licensed Louisiana attorney must confirm the current prescriptive rule and any applicable exception for latent environmental disease in your specific parish and court.
For claims against governmental entities — water utilities, LDEQ — the Louisiana Tort Claims Act imposes specific procedural notice requirements and statutory immunity limitations. These notice requirements have their own deadlines that may be shorter than the one-year prescription period, and missing them can bar a claim against a governmental defendant even when the substantive claim is strong. This is one of the easiest ways a strong case dies for a paperwork reason.
Louisiana’s Medical Malpractice Act damage caps do not apply to toxic tort cases. Punitive damages are generally disfavored in Louisiana and available only in narrowly defined statutory categories. The environmental context may implicate specific statutory provisions that a licensed Louisiana attorney should verify — but do not assume punitive damages are available in your case without that confirmation.
The Regulatory Rollback — and Why It Does Not Change Your Legal Rights
The federal regulatory landscape for PFAS in drinking water has been volatile, and the volatility is part of your case.
In April 2024, the Biden administration’s EPA issued the first enforceable federal limits on PFAS in drinking water — the National Primary Drinking Water Regulation for PFAS. The rule set the Maximum Contaminant Level for PFOA and PFOS at four parts per trillion each. The Maximum Contaminant Level Goal — the level at which there is no known or expected health risk — was set at zero. The compliance deadline was 2029. Initial monitoring was required by April 2027.
In May 2025, the Trump administration partially rolled back those regulations. The compliance deadline was pushed from 2029 to 2031. Certain PFAS maximum contaminant levels were removed entirely. The rollback means that for some PFAS compounds, there is no longer an enforceable federal limit in effect — even though the science that led to the regulation has not changed.
Here is what the rollback does not do: it does not change the science. It does not change the fact that PFAS are in your water. It does not change the medical consensus that no level of PFAS exposure is safe. It does not change the products liability claims against the manufacturers who designed chemicals that cannot break down. It does not change the Clean Water Act’s prohibition on discharging pollutants without a permit. It does not change CERCLA’s 2024 designation of PFOA and PFOS as hazardous substances — a designation that creates cleanup-cost recovery and natural-resource-damage pathways and makes the company that released them responsible for remediation.
What the rollback does do is make the regulatory standard argument harder for below-limit detections. If the enforceable limit for a specific PFAS compound has been removed, the defense will argue there is no standard to violate. The counter is twofold: first, the regulatory rollback does not retroactively erase violations that occurred while the standard was in effect. Second, the absence of an enforceable limit does not eliminate the common-law duties — the duty to warn, the duty not to create a public nuisance, the duty not to sell a product that is unreasonably dangerous — that exist independent of any federal regulation. A chemical manufacturer whose product contaminated your water cannot defend itself by saying the government decided to stop regulating it.
The EPA’s Lead and Copper Rule continues to impose monitoring and treatment requirements on water systems for lead contamination. The arsenic standard remains at a maximum contaminant level of 10 parts per billion. These are still enforceable. The lead in 67 percent of samples and the arsenic in 70 percent are subject to regulatory scrutiny regardless of what happened to the PFAS limits.
What Your Case Could Be Worth
We are going to give you honest numbers, and we are going to tell you exactly what makes the difference between the low end and the high end.
Medical monitoring claims — $50,000 to $150,000 per plaintiff. This is the baseline value for a resident with documented PFAS exposure through contaminated drinking water, no diagnosed disease, and sub-regulatory-limit exposure levels. Medical monitoring means the cost of blood serum PFAS testing to establish your body burden, plus longitudinal medical surveillance for the conditions the scientific literature links to PFAS exposure — thyroid function testing, liver enzyme panels, lipid panels, and for children, immune response monitoring. Medical monitoring is a recognized remedy for low-level, chronic, bioaccumulative exposure. It compensates the cost of watching for a disease you are at elevated risk of developing, even if you have not developed it yet. The scientific consensus that no PFAS exposure level is safe is the foundation of this claim — it means even below-limit exposure creates a medically justified need for surveillance.
Diagnosed disease claims — $750,000 to $3,000,000+ per plaintiff. This range applies when a plaintiff has been diagnosed with a PFAS-linked disease — thyroid cancer, kidney cancer, testicular cancer, liver disease, or pediatric immune impairment — AND an industrial source defendant has been identified through environmental forensics AND documented above-limit exposure can be tied to that source. At this level, the case includes the medical monitoring baseline plus treatment costs, lost earning capacity, pain and suffering, and in fatal cases, survival and wrongful-death damages. Louisiana survival actions preserve the decedent’s pre-death claims, and wrongful-death claims compensate the surviving family members.
Aggregate mass tort value. If a single industrial source or water system defendant is identified across the seven-parish exposure zone, the aggregate mass tort value could reach tens of millions of dollars. The seven-parish study area encompasses hundreds of thousands of residents. Even at the medical monitoring baseline, the numbers compound quickly across a population of that size.
The deflator. The critical deflator is causation attribution. No specific defendant is identified in the study. The majority of detections fall below enforceable federal limits. Without a source defendant identified through environmental forensics, individual case value is highly speculative. These ranges assume a source defendant is identified. Without that identification, the case is significantly harder to value and significantly harder to win. That is the honest truth, and you deserve to hear it before you make any decision about your legal rights.
Past results depend on the facts of each case and do not guarantee future outcomes. The firm has recovered more than $50 million for injured clients across its history, including a $5 million brain-injury settlement, a $3.8 million amputation settlement, and a $2.5 million truck-crash recovery. Those cases were built on identified defendants and proven causation. A PFAS case in Southeast Louisiana requires the same foundation — and building it starts with evidence that is disappearing right now.
The Evidence That Is Disappearing Right Now
Every toxic tort case is a race against a clock you cannot see. The records that prove what was in your water, who put it there, and what the responsible parties knew are on retention schedules that will legally permit their destruction while you are still deciding whether to act. Here is what exists, who holds it, and how fast it can die.
Water Collaborative study raw data, chain-of-custody records, and laboratory analysis packets. These establish the baseline contamination levels, geographic distribution, and demographic disparities that are central to your exposure proof and the environmental justice framing. The study’s published findings are available, but the underlying lab packets and methodology data may be available only briefly. Request them immediately from the Water Collaborative of Greater New Orleans.
Historical water utility testing records, Consumer Confidence Reports, and LDEQ compliance correspondence for all seven parish systems. These demonstrate whether water system operators knew or should have known about PFAS, lead, and arsenic contamination and failed to warn or treat. Retention schedules vary. Some records may be discarded on three-to-five-year cycles. Issue preservation letters immediately to every utility that served your household.
NPDES discharge permits, discharge monitoring reports, and enforcement records for industrial facilities along the Mississippi River corridor. These identify PFAS and heavy metal point-source contributors and establish regulatory notice of their discharges. LDEQ and EPA retention schedules apply, but facilities may destroy internal monitoring data on their own schedules. Preservation letters to identified facilities are urgent — and the facilities can only be identified once the environmental forensics begin to match chemical fingerprints.
Blood serum PFAS testing from affected residents. This is the evidence that establishes your individual body burden and the specific causation linking your water exposure to biological absorption. PFAS half-lives in human serum are measured in years, but baseline testing should occur before any voluntary exposure reduction — such as installing a water filter or switching to bottled water — confounds the results by lowering your serum levels before the baseline is established. If you are going to get tested, do it before you change your water source. The blood test is the proof that the chemicals in your water ended up in your body.
AFFF use and storage records from nearby military installations, airports, and industrial facilities. Firefighting foam is a primary PFAS source, and historical use records may identify a concentrated point source. Military base records are subject to federal records schedules, and the Department of Defense has been destroying certain legacy foam stockpiles. Request preservation now — once the stockpiles and their documentation are gone, the PFAS source attribution becomes significantly harder.
Plumbing and service-line material records from municipal water systems. These distinguish lead contamination originating from utility-owned service lines versus private plumbing, which allocates liability between the utility and the property owner. Infrastructure replacement projects — which are ongoing in New Orleans and other corridor systems — may destroy or remove the very evidence needed. Document current pipe materials before upgrades replace them.
The preservation letter is the single most important first step. It is a written demand that the entity — the water utility, the industrial facility, the military installation — freeze all relevant records and not destroy them pending litigation. The day you call us is the day that letter goes out. Not after the investigation. Not after the lawsuit is filed. That day. Because the records that prove your case are on a clock, and the clock is already running.
What the Defense Will Try — and How We Counter It
Every mass exposure case has a defense playbook, and PFAS water contamination is no exception. Here are the plays you should expect, and the counter to each one.
Play 1: “The detections were below enforceable federal limits.” The defense will point to the fact that most PFAS detections in the study fell below the federal Maximum Contaminant Level of four parts per trillion and argue that below-limit exposure cannot support a claim. The counter: the enforceable limit is a detection threshold, not a safety threshold. EPA’s own Maximum Contaminant Level Goal is zero. The medical consensus, stated by the study’s own toxicologist, is that no level of PFAS exposure is safe. The federal government set the legal limit at four parts per trillion because that is the lowest level current testing methods can reliably detect — not because four parts per trillion is safe. Medical monitoring is a recognized remedy precisely for this situation: chronic, low-level, bioaccumulative exposure that creates a medically justified need for surveillance even absent a current disease diagnosis.
Play 2: “Everyone has PFAS in their blood — you cannot prove our client caused yours.” PFAS are ubiquitous. The CDC’s National Health and Nutrition Examination Survey has found PFAS in the blood of nearly every American tested. The defense will argue that you cannot distinguish background exposure from the contaminated water. The counter: blood serum testing combined with water quality data and residence history can establish an elevated body burden above national background levels. If your serum PFAS concentrations are significantly higher than NHANES national averages, and your drinking water source is contaminated, the differential supports a specific causation argument. The C8 Science Panel’s methodology — using population-level exposure data to establish probable links — provides a scientific framework for attributing disease risk to a specific water source.
Play 3: “The lead and arsenic came from your own plumbing, not our water system.” For the heavy metal contamination found in 67 percent (lead) and 70 percent (arsenic) of samples, the defense will try to allocate fault to the resident’s private plumbing. The counter: the study documented that Black and lower-income households recorded the highest heavy metal concentrations, and that disparity appeared across income and educational differences. When the highest contamination hits the households least likely to have recently updated private plumbing — and most likely to be served by aging municipal infrastructure — the allocation of fault to the resident is not just weak, it is an environmental justice failure that a jury will understand.
Play 4: “The government rolled back the regulations, so there is no standard to violate.” The defense will cite the Trump administration’s May 2025 rollback of certain PFAS limits as proof that the regulatory standard no longer exists. The counter: the rollback does not retroactively erase violations that occurred while the standard was in effect. More fundamentally, the common-law duties — to warn, to avoid creating a public nuisance, to not sell a product that is unreasonably dangerous — exist independent of federal regulation. A chemical manufacturer whose product contaminated your water cannot defend itself by pointing to a regulatory rollback that came after the contamination was discovered.
Play 5: Delay. The defense will extend discovery, challenge expert admissibility, file motions to dismiss, and run the prescriptive clock. In Louisiana, the one-year prescription period is already short. The defense knows this. Every month of delay is a month closer to prescription. The counter: act early, preserve evidence immediately, and have a Louisiana-licensed attorney confirm the prescriptive rule and any discovery-rule extension that applies to your specific situation.

How a PFAS Case Is Actually Built
Here is the chronological walk of how a mass exposure water contamination case is constructed, from the day you call to the day a number is on the table.
Week one: preservation. The day you call, preservation letters go out to every entity that may hold relevant evidence — the water utility that served your home, LDEQ, and any industrial facilities the initial source-attribution analysis identifies. The letters demand that all water quality testing records, Consumer Confidence Reports, discharge monitoring reports, AFFF use records, and plumbing material records be frozen and not destroyed pending litigation. This is the most time-critical step in the entire case. Records on three-to-five-year retention cycles can be legally destroyed while you are still deciding whether to file.
Weeks two through four: blood serum testing and medical documentation. You are connected with a qualified environmental medicine specialist for blood serum PFAS testing — before you install a water filter or switch water sources, so the baseline reflects your actual exposure. You document any household member’s diagnosis of thyroid disease, liver enzyme abnormalities, high cholesterol, or pediatric immune issues. These records establish your individual damages and link the exposure to biological absorption.
Months one through three: environmental forensics. A hydrogeologist and environmental chemist perform source attribution analysis. They correlate the PFAS compound signatures in your tap water — the specific mix of PFOA, PFOS, and the other five detected compounds — with known industrial dischargers, AFFF use sites, and chemical manufacturing facilities along the Mississippi River corridor. NPDES discharge monitoring reports are subpoenaed. LDEQ inspection and enforcement records are pulled. Internal corporate documents from facilities whose chemical fingerprint matches the residential sample profile are targeted in discovery.
Months three through six: the national MDL connection. The national AFFF and PFAS multidistrict litigation provides a roadmap for expert selection, causation methodology, and regulatory-history development. Coordinating with co-counsel in the MDL avoids duplicative discovery and leverages existing document productions — the internal corporate emails, the internal testing data, the internal knowledge-of-hazard documents that the manufacturers have already been forced to produce in other cases.
Months six through twelve: discovery and depositions. The records come out. The water utility’s testing history reveals what it knew and when. The industrial facility’s discharge reports show what it released and in what quantities. The chemical manufacturer’s internal documents show what it knew about persistence and health risks — and when it knew it. The depositions are where the safety director, the plant manager, and the corporate representative explain the company’s choices under oath.
The number. The number at the end is built from all of it — the blood serum results, the medical monitoring cost analysis, the disease-risk projection, the life-care plan if disease is diagnosed, the property devaluation if municipal water contamination diminishes home values, and the non-economic damages for the anxiety and emotional distress of chronic exposure to bioaccumulative carcinogenic substances. A well-documented medical-monitoring cost analysis and disease-risk projection is what pressures excess carriers once liability clarity improves through source identification. This is not a process that can be rushed. It is also not a process that can be delayed. The evidence clock and the prescriptive clock are running simultaneously.
What to Do in the First 72 Hours
Here is the practical roadmap for what to do right now, today, this week — not next month, not after you talk to your neighbor about it, not after you see whether the government does anything.
Do get blood serum PFAS testing through your physician or a qualified environmental medicine specialist. This is the single most important medical step. The test documents your body burden — the amount of PFAS actually in your blood — and establishes the baseline before any exposure reduction confounds the results. Tell your doctor you live in one of the seven parishes where the water quality study found contamination, and ask for a PFAS serum panel. If your doctor does not offer the test, ask for a referral to an environmental medicine specialist.
Do document any household member’s diagnosis of conditions linked to PFAS exposure. If anyone in your household has been diagnosed with thyroid disease, liver enzyme abnormalities, high cholesterol that appeared without obvious dietary cause, or if your children have had reduced vaccine response or frequent infections, document it. Request complete medical records. These diagnoses, combined with your water exposure history, are the foundation of a personal injury or medical monitoring claim.
Do preserve your water quality data. If you have had your water tested independently, keep the results. If you have not, consider having your tap water tested by a certified laboratory that can detect PFAS at parts-per-trillion levels. Keep copies of your water utility’s Consumer Confidence Reports for every year you have lived at your current address.
Do not sign anything from your water utility, an insurance company, or anyone offering to “resolve” your concerns. A release is a legal document that extinguishes your right to sue. In the weeks and months after contamination becomes public, entities responsible for the water system may offer “settlements” or “credits” that come with a release attached. Do not sign anything without having it reviewed by a lawyer.
Do not give a recorded statement to any insurance adjuster, water utility representative, or investigator. A recorded statement is engineered to be quoted against you. The person asking the questions is not your friend. They are building a file to minimize or deny your claim. You have no obligation to provide a recorded statement to anyone at this stage.
Do not delay. Louisiana’s prescriptive period is one year from the date the damage is sustained or discovered. The discovery rule may extend that window for latent injuries, but the safe assumption is that the clock started when the study was published and you learned your water was contaminated. Every day you wait is a day closer to prescription and a day the evidence continues to degrade.
Do install a water filter certified for PFAS reduction. This is a practical health step, not a legal one. Reverse osmosis systems and certain activated carbon filters certified under NSF/ANSI standards for PFAS reduction can reduce the PFAS in your drinking water. Boiling water does not remove PFAS — it concentrates them. Bottled water is not necessarily PFAS-free unless it has been specifically tested. But note: if you plan to get blood serum testing, get tested before you change your water source, so the baseline reflects your actual historical exposure.
Do call us. The consultation is free, it is confidential, and it costs you nothing. We work on contingency — we do not get paid unless we win your case. The call is the first step in the preservation process, because the day you call is the day the evidence-preservation letters can go out.
Environmental Justice: The Disparity the Study Documented
The water quality study did not just find contamination. It found that the contamination was not distributed equally. Black and lower-income households recorded the highest concentrations of heavy metals — the lead and arsenic that can damage developing brains and organs. Households with a high school education or less, and those earning under $25,000 a year, recorded the highest peaks in heavy metal exposure. More educated, higher-income groups recorded generally lower levels.
PFAS contamination, by contrast, appeared more uniformly across race, education, and income — because PFAS dissolves in water and travels through municipal systems regardless of who is drinking it at the other end.
That disparity is both a legal claim component and a community-mobilization reality. It is a legal claim component because the documented racial and socioeconomic disparities in heavy metal exposure may support claims under equal-protection or disparate-impact theories, particularly where municipal infrastructure decisions disproportionately burden Black and low-income communities. The lead service lines that serve predominantly Black and lower-income neighborhoods are not there by accident. They are there because of decades of infrastructure decisions that prioritized some neighborhoods over others.
It is a community-mobilization reality because the families who are bearing the highest contaminant burdens are often the families with the least access to legal resources, the least ability to install expensive water filtration systems, and the least political capital to demand that their water utility test and treat their water. The study’s findings should be communicated factually: Black and lower-income households carried the highest heavy metal concentrations. That disparity is documented. It is in the data. And it is part of the case.
Frequently Asked Questions
What are PFAS “forever chemicals”?
PFAS are per- and polyfluoroalkyl substances — a family of thousands of synthetic chemicals used since the 1940s in nonstick cookware, waterproof clothing, food packaging, cleaning products, carpets, and firefighting foam. They are called “forever chemicals” because they do not naturally degrade in the environment or in the human body. Once they enter your bloodstream through contaminated drinking water, they persist for years. The half-life of PFOA in human serum is approximately two to four years, meaning half the PFOA in your blood today will still be there in three years even if you stop all exposure.
Can I sue if my water has PFAS but it is below the legal limit?
Yes — potentially. The federal Maximum Contaminant Level for PFOA and PFOS is four parts per trillion, but that number is a detection threshold, not a safety threshold. EPA’s own health goal is zero. The medical consensus is that no level of PFAS exposure is safe. Even below-limit exposure can support a medical monitoring claim — a recognized legal remedy that compensates the cost of ongoing medical surveillance for conditions linked to the exposure. The absence of a diagnosed disease does not mean you have no claim. It means your claim is for monitoring, not for treatment — and that claim is worth $50,000 to $150,000 per plaintiff in cases with confirmed exposure and no diagnosed disease.
How long do I have to file a claim in Louisiana?
Louisiana’s prescriptive period for delictual actions — the equivalent of a statute of limitations in other states — generally runs one year from the date the damage is sustained or discovered. For toxic tort cases involving latent injuries, the prescription-discovery analysis may extend the filing window, because the clock may not start until you discover, or should have discovered through reasonable diligence, that your water was contaminated and that the contamination caused your injury. The publication of the water quality study may be the triggering event for many residents. A licensed Louisiana attorney must confirm the current prescriptive rule and any applicable exception for your specific situation. Do not assume you have plenty of time — Louisiana’s clock is shorter than most states.
What health conditions are linked to PFAS exposure?
The scientific literature links PFAS exposure to high cholesterol, liver damage, thyroid disease, reduced vaccine response in children, kidney cancer, testicular cancer, pregnancy-induced hypertension, and ulcerative colitis. The C8 Science Panel — independent epidemiologists who studied nearly 70,000 people exposed to PFOA-contaminated water — found “probable links” between PFOA and six specific conditions. IARC, the world’s leading cancer authority, classified PFOA as a Group 1 known human carcinogen in 2024. If you or a family member has been diagnosed with any of these conditions and you live in one of the seven affected parishes, document the diagnosis and your water exposure history.
Should I get my blood tested for PFAS?
Yes — and do it before you install a water filter or switch to bottled water. Blood serum PFAS testing measures your body burden — the amount of these chemicals actually in your blood. It does not diagnose disease. It documents exposure. The baseline test should reflect your actual historical exposure, not your exposure after you have reduced it. If you install a reverse osmosis filter today and get tested in six months, your serum levels will have dropped — and the test will understate your actual exposure. Get tested first. Then filter your water. The blood test is the proof that the chemicals in your water ended up in your body.
Who is responsible for the PFAS in my water?
Identifying the responsible party requires environmental forensics. Potential defendants include PFAS chemical manufacturers (companies that designed and sold the chemicals), industrial facilities along the Mississippi River corridor that discharged PFAS into source waters, military installations and airports that used PFAS-containing firefighting foam, municipal water utilities that failed to monitor, treat, or warn, and LDEQ for regulatory oversight. The study identified contamination but did not name a specific source defendant. Source attribution analysis — matching the chemical fingerprint in your tap water to known dischargers — is the investigation that identifies the responsible party. That investigation is the foundation of the case.
What is medical monitoring and how much is it worth?
Medical monitoring is a recognized legal remedy that compensates the cost of ongoing medical surveillance for conditions a person is at elevated risk of developing due to documented exposure to a hazardous substance. In PFAS cases, it includes blood serum testing to establish body burden, plus longitudinal testing for thyroid function, liver enzymes, lipid panels, and — for children — immune response monitoring. The case value for medical monitoring claims ranges from $50,000 to $150,000 per plaintiff, assuming confirmed exposure through contaminated drinking water, sub-regulatory-limit levels, and no diagnosed disease. The scientific consensus that no PFAS exposure level is safe is the legal foundation — it means even below-limit exposure creates a medically justified need for surveillance.
The government rolled back the PFAS limits — does that affect my case?
The regulatory rollback affects the regulatory standard argument but not the common-law claims. The Trump administration’s May 2025 rollback extended the compliance deadline from 2029 to 2031 and removed certain PFAS maximum contaminant levels. But the rollback does not change the science, does not change the fact that PFAS are in your water, does not retroactively erase violations that occurred while the standard was in effect, and does not eliminate the common-law duties to warn, to avoid creating a public nuisance, and to not sell a product that is unreasonably dangerous. The CERCLA designation of PFOA and PFOS as hazardous substances — which creates cleanup-cost recovery pathways — also remains in effect. A chemical manufacturer whose product contaminated your water cannot defend itself by pointing to a regulatory rollback.
The study found environmental justice disparities — does that matter legally?
Yes. The documented racial and socioeconomic disparities in heavy metal exposure — Black and lower-income households bearing the highest lead and arsenic concentrations — may support claims under equal-protection or disparate-impact theories, particularly where municipal infrastructure decisions disproportionately burden specific communities. The disparity is also a damages narrative anchor: it counters any comparative-fault defense that blames residents for aging private plumbing, because the households least likely to have updated plumbing are the ones bearing the highest contaminant burdens. And it is a community-mobilization reality that can drive coordinated action across the seven-parish exposure zone.
Can I still drink my tap water?
The study found PFAS in 105 of 107 homes, lead in 67 percent, arsenic in 70 percent, and salt exceeding EPA thresholds in 100 percent of low-river samples. The medical consensus is that no level of PFAS exposure is safe. From a health perspective, installing a water filter certified for PFAS reduction — specifically a reverse osmosis system or an activated carbon filter certified under NSF/ANSI standards for PFAS reduction — is a prudent step. Boiling water does not remove PFAS. It concentrates them. Bottled water is not necessarily PFAS-free unless it has been specifically tested. From a legal perspective, if you plan to get blood serum PFAS testing, get tested before you change your water source, so the baseline reflects your actual historical exposure. This page is legal information, not medical advice — consult your physician for guidance specific to your health situation.
Will a home water filter remove PFAS?
Some will, some will not. Reverse osmosis systems are the most effective at removing PFAS from drinking water. Certain activated carbon filters certified under NSF/ANSI standards for PFAS reduction can also be effective, but not all carbon filters are certified for PFAS. A standard pitcher filter is unlikely to remove PFAS at parts-per-trillion levels. Look for filters certified specifically for PFOA and PFOS reduction. But again: if you plan to get blood serum testing for a legal case, get tested before you install the filter. The blood test needs to reflect your actual exposure history, not your post-filtration exposure.
