The Forever Problem

In this episode, we begin Season 3 by exploring one of the most important questions about PFAS: How do these forever chemicals get inside the human body? Once PFAS enter the environment, they can reach people through several everyday pathways. Drinking water is one of the most studied sources, but exposure can also come from food, household dust, personal care products, and even before birth. Unde...

In this episode, we wrap up Season 2 by exploring one of the most important questions in PFAS research: How do scientists detect something they cannot see, smell, or taste? PFAS often exist at incredibly small concentrations, measured in parts per billion or even parts per trillion. To put that into perspective, a single part per trillion is an almost unimaginably tiny amount. Yet scientists can s...

In this episode, we explore whether PFAS can move from contaminated water into the food we eat. After learning how PFAS travel through water, soil, and air, this episode looks at what happens when irrigation water contains forever chemicals. The big question is simple but important: can plants absorb PFAS even when the water looks clean and the crops appear healthy? We break down a research experi...

In this episode, we explore one of the most important questions about PFAS: How do they end up everywhere? PFAS, often called “forever chemicals,” are not only incredibly persistent but also highly mobile. Once they enter the environment through industrial discharge, firefighting foams, landfills, or wastewater, they can dissolve in water and travel long distances. Groundwater, rivers, and streams...

In this episode, we focus on the one thing that explains the entire PFAS problem: a single chemical bond. PFAS, known as “forever chemicals,” do not break down because of the carbon-fluorine bond at their core. Most materials in nature break apart over time through sunlight, water, oxygen, or microbes. But PFAS are different. Their structure is built to resist all of these natural processes, which...

In this episode, we begin a new chapter by breaking down the science behind PFAS in a simple and clear way. PFAS, known as “forever chemicals,” are built from strong chemical bonds that do not easily break down. Instead of complex terms, this episode explains the basics. Everything is made of atoms, and when atoms connect, they form molecules. The way those atoms bond determines how stable a subst...

In this episode, we break down a question many people are asking: Are PFAS really a serious problem, or is this being overblown? PFAS, known as “forever chemicals,” are everywhere, but the conversation around their risk is more complex than it seems. Some argue that we are exposed to many chemicals daily and that low-level exposure does not always mean danger. They point out that regulatory limits...

In this episode, we explore a question that surprises many people: How did PFAS end up everywhere without us even noticing? PFAS, often called “forever chemicals,” were not accidental contaminants. They were intentionally created and widely used because of their unique properties. Starting in the mid-20th century, fluorinated chemicals like Teflon transformed manufacturing. They resisted heat, wat...

In this episode, we tackle a frustrating but important question: If PFAS are dangerous, why can’t scientists just get rid of them? PFAS, a type of PFAS known as “forever chemicals,” were engineered to resist heat, water, and oil. At the core of the problem is chemistry. The carbon–fluorine bond that makes PFAS so useful is also one of the strongest chemical bonds on Earth. These compounds do not b...

In this episode, we uncover how PFOS (perfluorooctane sulfonate) — a type of PFAS forever chemical — quietly shows up in everyday products. From food packaging and athleisure to cosmetics and drinking water, PFOS are not locked away in labs. They are in our homes, our schools, and even our daily routines. These chemicals were designed to resist heat, oil, and water, but that same strength makes th...

In this first episode, we introduce The Forever Problem and unpack a question most people have never been asked: what if something in your life never goes away? Sahana explains PFAS, often called “forever chemicals,” substances designed to resist heat, water, and time. These chemicals don’t break down, don’t disappear, and are now found in our environment, our food, and our bodies. You can’t see t...
