Trend watch: PFAS remediation & emerging contaminants in 2026 — signals, winners, and red flags

Global spending on PFAS remediation surpassed $2.8 billion in 2025, up 63% from the prior year, according to the Environmental Business Journal. The acceleration reflects a convergence of regulatory deadlines, litigation settlements, and advancing destruction technologies that are finally moving beyond containment toward permanent elimination of per- and polyfluoroalkyl substances. This trend watch identifies the signals shaping PFAS remediation and emerging contaminants management in 2026, the technologies and companies gaining ground, and the red flags that could stall progress.

Why It Matters

PFAS are a class of more than 14,000 synthetic chemicals used since the 1940s in everything from nonstick cookware and food packaging to firefighting foam and semiconductor manufacturing. Their carbon-fluorine bonds resist natural degradation, earning them the label "forever chemicals." PFAS contamination has been detected in the drinking water of over 110 million people in the United States alone, according to the U.S. Geological Survey. In Europe, a 2023 investigation by Le Monde and partners identified more than 17,000 contaminated sites across the continent.

The health implications are severe and well-documented. PFAS exposure is linked to elevated cancer risk, thyroid disease, immune suppression, reproductive disorders, and developmental delays in children. The U.S. EPA established enforceable maximum contaminant levels (MCLs) for six PFAS compounds in drinking water in 2024, with compliance deadlines beginning in 2027. The EU adopted a universal PFAS restriction proposal under REACH that would ban all non-essential PFAS uses, with phased implementation starting in 2026.

The financial exposure is equally significant. PFAS-related litigation in the U.S. alone has generated over $12 billion in settlements since 2023, with 3M's $10.3 billion water utility settlement and DuPont/Chemours' $1.18 billion agreement representing landmark payouts. Manufacturers, water utilities, military installations, and airports face remediation costs that regulators and courts are increasingly pushing back to polluters. For municipalities and water utilities, the cost of compliance with new MCLs is estimated at $1.5 billion annually in the U.S., driving urgent demand for cost-effective treatment solutions.

Key Concepts

PFAS destruction technologies break the carbon-fluorine bond to permanently eliminate PFAS, as opposed to removal technologies that concentrate PFAS into waste streams requiring further management. Leading destruction approaches include supercritical water oxidation, electrochemical oxidation, and plasma-based treatment.

Granular activated carbon (GAC) and ion exchange resins are the dominant removal technologies currently deployed at water treatment facilities. These methods effectively capture PFAS from water but generate spent media that must be disposed of or regenerated, creating secondary waste management challenges.

Emerging contaminants extend beyond PFAS to include pharmaceuticals, microplastics, 1,4-dioxane, and endocrine-disrupting compounds. Regulatory frameworks are beginning to address these substances collectively under integrated contaminant management approaches rather than chemical-by-chemical regulation.

Total organic fluorine (TOF) measurement quantifies the aggregate fluorine content in a sample rather than testing for individual PFAS compounds. This approach addresses the limitation of targeted analytical methods that test for only 30-50 specific PFAS while thousands of compounds exist.

What's Working

Revive Environmental's supercritical water oxidation (SCWO) systems have demonstrated 99.99% destruction efficiency for PFAS in concentrated waste streams, including aqueous film-forming foam (AFFF) concentrates and landfill leachate. The company deployed its first commercial-scale unit in 2024 and has contracts with the U.S. Department of Defense for AFFF stockpile destruction at military installations. SCWO operates at temperatures above 374 degrees Celsius and pressures exceeding 221 bar, converting PFAS into simple salts, water, and carbon dioxide. By late 2025, Revive had processed over 500,000 gallons of AFFF concentrate across three operational sites.

Aclarity's electrochemical oxidation platform offers a modular, on-site treatment approach that destroys PFAS in water without generating secondary waste. The system uses boron-doped diamond electrodes to generate hydroxyl radicals that break carbon-fluorine bonds. Aclarity has deployed systems at landfills and industrial facilities across the northeastern United States, with reported destruction rates exceeding 95% for short-chain and long-chain PFAS. The modular design allows utilities to scale treatment capacity incrementally, avoiding the capital burden of centralized treatment plant upgrades.

The EU's integrated approach to PFAS restriction under REACH represents the most comprehensive regulatory framework globally. Rather than regulating individual compounds, the proposal restricts the entire class of PFAS, with exemptions only for essential uses where no alternatives exist. Denmark, Germany, the Netherlands, Norway, and Sweden jointly submitted the restriction dossier, and the European Chemicals Agency (ECHA) has advanced it through public consultation. The framework provides industry with clear phase-out timelines while driving innovation in PFAS-free alternatives for textiles, food contact materials, and industrial applications.

What's Not Working

Landfill disposal of PFAS-contaminated materials without destruction continues to redistribute contamination rather than eliminate it. Spent GAC, ion exchange resins, and PFAS-laden biosolids are commonly sent to lined landfills, where PFAS leach into leachate that must itself be treated. A 2025 study by the Environmental Science and Technology journal found detectable PFAS in leachate at 98% of tested municipal landfills in the U.S. This circular contamination pathway means removal-only approaches are deferring the problem rather than solving it.

Incineration at conventional temperatures fails to destroy PFAS reliably. Standard municipal waste incinerators operating at 850-1,100 degrees Celsius may not achieve complete defluorination of PFAS compounds, potentially releasing fluorinated byproducts into air emissions or concentrating them in ash. Research published in Environmental Science and Technology Letters in 2025 demonstrated that certain PFAS transformation products survived conventional incineration, challenging the assumption that thermal treatment is a universal solution. Only specialized high-temperature incineration (>1,100 degrees Celsius) with appropriate residence times and emissions controls has demonstrated reliable destruction.

Analytical testing bottlenecks are slowing compliance timelines. The surge in PFAS monitoring requirements has overwhelmed laboratory capacity. Certified labs capable of EPA Method 533 and 537.1 analyses face 6-12 week backlogs in many regions, delaying utilities' ability to characterize contamination levels and design treatment responses. Testing costs of $300-600 per sample for targeted PFAS analysis, and $1,000+ for total organic fluorine measurements, create significant financial burdens for small water systems serving under 10,000 people.

PFAS-free alternatives in critical industrial applications remain performance-limited. While alternatives exist for many consumer products, sectors like semiconductor manufacturing, medical devices, and aerospace rely on PFAS for properties (chemical resistance, low friction, dielectric performance) that current substitutes cannot fully replicate. Blanket restriction timelines that do not account for these technical gaps risk disrupting essential manufacturing processes before viable alternatives mature.

Red Flags

Treatment technology fragmentation without performance standards. The rapid emergence of PFAS destruction technologies has outpaced standardization. Without established benchmarks for destruction efficiency, byproduct formation, energy consumption, and cost per unit treated, utilities and regulators cannot effectively compare solutions. The absence of EPA-validated performance protocols for destruction technologies (as opposed to removal) risks creating a market where unproven claims attract capital while proven solutions struggle for recognition.

Small water system compliance gaps. Over 45,000 community water systems in the U.S. serve populations under 10,000, and many lack the technical and financial capacity to implement PFAS treatment. Federal funding through the Bipartisan Infrastructure Law addresses part of the capital cost, but ongoing operational expenses for treatment media replacement, monitoring, and waste disposal may be unsustainable for systems with limited rate bases. Without targeted assistance, these communities face either noncompliance or severe rate increases.

Regrettable substitution creating next-generation contamination. As PFAS are phased out, some replacement chemicals have themselves raised toxicity concerns. GenX, a PFOA replacement manufactured by Chemours, is now regulated as a contaminant in its own right. If industry replaces PFAS with structurally similar compounds that share persistence or toxicity characteristics, the remediation cycle repeats. Robust premarket toxicity assessment for PFAS alternatives is essential to prevent creating new "forever chemical" problems.

Biosolids and agricultural contamination pathways expanding. PFAS-contaminated biosolids from wastewater treatment plants have been applied to agricultural land for decades, creating soil and groundwater contamination in farming communities. Maine banned the land application of biosolids in 2022, and other states are considering similar restrictions. Without cost-effective PFAS removal from biosolids or alternative disposal pathways, wastewater utilities face mounting storage and disposal costs that could exceed $1 billion annually nationwide.

• Establish ongoing monitoring programs that track emerging contaminants beyond currently regulated PFAS compounds

FAQ

What are the most effective technologies for removing PFAS from drinking water? Granular activated carbon (GAC) and anion exchange resins are the most widely deployed and proven technologies for PFAS removal from drinking water. GAC is effective for long-chain PFAS like PFOA and PFOS, while ion exchange resins offer better performance for short-chain compounds. High-pressure membrane systems like nanofiltration and reverse osmosis achieve removal rates above 95% for most PFAS but generate concentrated reject streams requiring further management. The choice depends on influent concentrations, water chemistry, flow rates, and budget constraints.

How much does PFAS treatment cost for a typical water utility? Costs vary significantly by system size, contamination level, and technology choice. For a mid-sized utility serving 50,000 people, capital costs for GAC treatment range from $5 million to $15 million, with annual operating costs of $500,000 to $2 million for media replacement and monitoring. Smaller systems face disproportionately higher per-capita costs due to fixed infrastructure requirements. PFAS destruction technologies for concentrated waste streams add $15-50 per 1,000 gallons of treatment capacity, though costs are declining as the technology matures.

Can PFAS be permanently destroyed, or only removed from water? Yes, several technologies can permanently destroy PFAS by breaking the carbon-fluorine bond. Supercritical water oxidation, electrochemical oxidation, and high-temperature plasma systems have demonstrated destruction efficiencies exceeding 99% in pilot and commercial deployments. These technologies convert PFAS into inorganic fluoride salts, water, and carbon dioxide. However, destruction technologies are currently most cost-effective for concentrated waste streams rather than high-volume, low-concentration drinking water treatment, where removal followed by concentrated waste destruction is typically more economical.

What does the EU PFAS restriction mean for manufacturers? The proposed EU REACH restriction would ban all non-essential PFAS uses with phased implementation timelines. Manufacturers using PFAS in consumer products like textiles, food packaging, and cosmetics face the earliest phase-out requirements, potentially by 2027-2028. Industrial applications with demonstrated essential uses, such as semiconductor manufacturing, medical devices, and certain fluoropolymer applications, would receive longer transition periods of 5-12 years. Companies should inventory all PFAS uses in their products and supply chains, identify available alternatives, and begin qualification testing for substitutes now.
