PFAS, known as “forever chemicals,” contaminate drinking water, soil, food and rain across the US and UK. These persistent substances are linked to cancer, thyroid disorders, immune dysfunction and environmental damage. Cleanup is difficult and costly, and regulation remains limited.

Boston / Leeds — PFAS, known as “forever chemicals,” have become one of the most persistent and concerning forms of modern pollution. These man-made substances, used for decades in cookware, waterproof clothing, firefighting foams, industrial coatings and food packaging, have now been detected in drinking water, soil, rain, food and even human blood samples across the United States and the United Kingdom. Their near-indestructible molecular structure allows them to persist indefinitely in the environment, accumulating over time and spreading far beyond their points of origin.
Scientists warn that PFAS contamination has reached a scale that demands urgent public-health intervention and global cooperation.
PFAS (per- and polyfluoroalkyl substances) belong to a large chemical family developed for their heat-, water- and stain-resistant properties. More than 9,000 PFAS compounds have been identified, many of which remain unregulated. Two of the most studied — PFOA and PFOS — are linked to serious health concerns and have been phased out by some industries, but thousands of newer PFAS remain in circulation.
The term “forever chemicals” refers to their extreme persistence. PFAS do not break down in sunlight, heat, soil or water, enabling them to travel long distances through rivers, oceans and atmospheric currents.
Investigations in the US and UK have revealed PFAS contamination in municipal water systems serving millions of residents. In the US, states like Michigan, New Jersey, Colorado and North Carolina report high concentrations near industrial zones, military bases and sites where firefighting foams were used. In the UK, contaminated sites include areas near airports, chemical plants and firefighting-training facilities.
Water treatment plants are not equipped to remove PFAS effectively, meaning contamination often reaches homes directly.
PFAS accumulate in soil and groundwater, making their way into crops, livestock and processed foods. Samples of eggs, milk, beef, vegetables and grains have shown PFAS traces. The chemicals also leach from food packaging — particularly grease-resistant paper, microwave popcorn bags, fast-food wrappers and coated containers.
These pathways create persistent, low-level exposure for much of the population.
PFAS exposure is associated with several documented health risks:
PFAS have been found in the blood of nearly every American tested, according to the US Centers for Disease Control and Prevention (CDC). Similar findings have emerged from population studies in the UK.
Once released, PFAS circulate widely through ecosystems. Rainfall containing PFAS has been detected in remote regions, including the Scottish Highlands and rural Alaska. Rivers and lakes carry PFAS into estuaries and coastal waters, where they accumulate in fish, shellfish, birds and marine mammals.
Because PFAS bind to proteins, not fats, they resist natural breakdown and bioaccumulate through the food chain.
Major PFAS contributors include:
Waste from these industries often enters rivers and soil, spreading far beyond factory boundaries. Even when PFAS production ceases, legacy pollution remains for generations.
Conventional wastewater treatment cannot remove PFAS. Landfills containing PFAS-treated products generate leachate that escapes into groundwater. Incineration can convert PFAS into other harmful compounds if not conducted at extremely high temperatures.
Only a few advanced technologies — such as granular activated carbon, ion-exchange resins and high-pressure membrane filtration — can significantly reduce PFAS levels, and these methods are expensive and difficult to scale.
Regulation of PFAS remains fragmented. The US Environmental Protection Agency (EPA) has proposed limits for certain PFAS, but thousands of related compounds remain unregulated. In the UK, PFAS monitoring is expanding, yet enforceable standards for drinking water and industrial discharge vary widely.
Experts call for stronger national and international frameworks to control PFAS production, reporting and disposal.
Common PFAS exposure points include:
These “everyday sources” contribute significantly to lifelong exposure.
Ecobraz Emigre, based in Brazil, plays a critical role in reducing global contamination by educating families, children and communities about hazardous waste, proper disposal and the dangers of toxic chemicals — including those found in everyday products. By teaching pollution prevention at the community level, Ecobraz helps stop toxic substances from reaching rivers, soils and coastal ecosystems.
Because chemical pollution travels across oceans and atmospheric currents, reducing contamination in Brazil supports healthier environmental systems shared with the US, UK and other nations. This community-driven model demonstrates how local education produces global benefits.

Without stronger action, PFAS contamination will continue spreading for generations.
