Global PFAS contamination is a crisis measured in trillions of dollars, millions of DALYs, and billions of affected lives. Current approaches focus on downstream cleanup — mopping the floor while the tap runs. This fund targets the source.
"The math is clear: destroy PFAS at the source."
Environmental engineer with 15+ years of water sector experience and a track record of designing and managing large-scale programs across Africa and Asia.
Why this matters: Deploying capital into upstream PFAS destruction infrastructure requires someone who combines deep technical water/environmental expertise with a proven ability to manage complex, multi-stakeholder programs at scale. Dr. Barstow's career spans both — from peer-reviewed environmental engineering research to operational leadership of programs reaching millions of people across dozens of countries.
Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals manufactured since the 1940s. Their carbon-fluorine bonds — among the strongest in chemistry — make them virtually indestructible in the environment, earning them the name "forever chemicals."
4,000–12,000 compounds estimated in commercial use. Only 6 are subject to drinking water regulations. The vast majority remain uncharacterized.
Non-stick coatings, firefighting foam (AFFF), food packaging, textiles, semiconductors, cosmetics, and thousands of industrial applications.
Kidney & testicular cancer, thyroid disease, immune suppression, reproductive harm, childhood obesity, chronic kidney disease, and more.
PFAS do not break down naturally. Global rainwater now exceeds drinking water safety thresholds. They have been detected in Arctic ice cores dating to the 1940s.
Interactive map of known PFAS manufacturing facilities and regional contamination hotspots. Manufacturing facilities (gold) represent just 0.04% of contamination sites but create concentrations 1,000–10,000× higher than downstream sources.
27 facilities from 12 companies compiled from the following sources:
Contamination hotspots are displayed as aggregated regional markers (not individual site-level data) to provide a readable overview of contamination concentration patterns. Each marker represents a geographic cluster derived from the source databases listed above. Manufacturing facility coordinates were individually verified against company disclosures and satellite imagery.
PFAS follow a predictable pathway from manufacturing to human exposure. The further downstream you intervene, the more diffuse the contamination becomes — and the more expensive cleanup gets. Point sources offer concentrated streams at identifiable facilities where destruction technologies can eliminate PFAS before environmental release.
The leverage point: Consumer products represent millions of diffuse household sources. Atmospheric deposition carries PFAS thousands of kilometers. But manufacturing facilities — just 30 globally — handle PFAS in pure, concentrated forms with contamination levels 1,000–10,000× higher than industrial users. Intervening here prevents contamination across all downstream pathways.
12 companies control majority of global PFAS output. Top 3 fluoropolymer producers (Chemours, Daikin, Solvay) hold ~83% market share. These facilities are the origin point for all downstream contamination.
Metal finishing (~15,000), textiles (~5,000), semiconductors (~1,000), and pulp/paper (~500). Geographically clustered in MI/OH, NC/SC, Bavaria, Shandong. Concentrated wastewater streams enable targeted destruction.
Military installations, airports, and fire departments store legacy foam awaiting proper disposal. State take-back programs (NH: 10,000+ gallons; OH: 200,000 liters) demonstrate collection is feasible. Industry estimates: 5+ years to eliminate at current capacity.
Using population attributable fraction methodology with stratified biomonitoring data, we estimate the annual health burden from legacy PFAS exposure across four key regions. These figures represent only PFOA and PFOS — just 2 of 4,000–12,000 compounds in commerce.
Key finding: Replacement PFAS likely generate burden in the millions of DALYs annually, though uncertainty is high. Of the 4,000–12,000 PFAS substances in commerce, only 6 have drinking water regulations. This monitoring gap means the vast majority of health effects remain unquantified while production continues.
Downstream PFAS remediation is extraordinarily expensive and often incomplete. Upstream destruction at point sources offers orders-of-magnitude better cost-effectiveness — before contamination disperses into soil, water, and biological systems.
Multiple technologies can achieve >99% destruction of PFAS compounds. The challenge is not technological feasibility — it's deploying capacity at the scale needed to match the contamination.
Uses water above its critical point (374°C, 221 bar) as a reaction medium. Fast kinetics, complete mineralization. Leading option for concentrated AFFF and industrial wastewater destruction.
Lower energy requirements than thermal methods. No extreme temperature or pressure conditions. Uses boron-doped diamond electrodes to generate reactive species that break C-F bonds.
Uses electrical discharges to create plasma that fragments PFAS molecules. Promising for mixed waste matrices. Several companies scaling up pilot systems for field deployment.
Uses subcritical water with sodium hydroxide to defluorinate PFAS through alkaline hydrolysis. Novel approach for PFAS in biosolids, contaminated soil, and solid waste matrices.
Regulation is accelerating globally — creating mandatory demand for destruction capacity. Every new MCL, product ban, and CERCLA designation strengthens the economic case for upstream destruction infrastructure.
The PFAS Destruction Fund deploys capital into upstream destruction infrastructure — targeting the concentrated point sources where intervention offers the highest leverage per dollar deployed.
Upstream PFAS destruction infrastructure at or near manufacturing facilities, major industrial users, and AFFF stockpile locations. Three-tier approach matching intervention to source concentration.
Proven destruction methods — supercritical water oxidation and electrochemical oxidation as primary; plasma-based and HALT as emerging. Deployment matched to waste stream characteristics.
Regulatory compliance fees (EPA MCL deadlines create mandatory demand), avoided liability (CERCLA designation drives proactive destruction), and potential contamination-prevention credit markets.
Tonnes of PFAS destroyed, contamination prevented (measured in avoided ppt-volume), communities protected, and DALYs averted through reduced exposure at source.
