The Forever Problem

What if the food on your plate contains chemicals you can't see, smell, or wash away? PFAS, also known as forever chemicals, can enter the food we eat long before it reaches our kitchen. From vegetables grown in contaminated soil and water to fish living in polluted rivers, these chemicals can move through our food supply without leaving any visible signs. In this episode of The Forever Problem ,...

In this episode, we explore how PFAS, also known as forever chemicals, affect wildlife and the ecosystems they call home. While much of the conversation around PFAS focuses on human health and contaminated drinking water, animals are often exposed long before these chemicals reach our homes. From fish swimming in polluted rivers to birds, dolphins, sea turtles, and polar bears living thousands of...

In this episode, we begin Season 4 by following PFAS through the environment and asking a simple but important question: **Where do forever chemicals go once they enter our water?** PFAS pollution doesn't always stay close to where it started. Rain can wash these chemicals from roads, industrial areas, landfills, and other sources into storm drains and streams. From there, streams connect to river...

In this episode, we wrap up Season 3 with one of the biggest questions surrounding forever chemicals: **Is there actually a safe level of PFAS?** Scientists rarely describe chemical exposure as simply “safe” or “unsafe.” Instead, they look at acceptable risk, health guidelines, and exposure limits. With PFAS, that question becomes especially complicated because some of these chemicals can remain i...

In this episode, we step away from molecules and lab results to look at the human side of PFAS contamination. For many communities, the first sign of a problem isn't strange-looking or bad-tasting water. PFAS are invisible, odorless, and tasteless, which means families can drink contaminated water for years without knowing it. We explore how PFAS can enter drinking water through industrial sites,...

In this episode, we explore how PFAS may affect one of the body's most important communication systems: hormones. Hormones act as chemical messengers, helping regulate growth, sleep, energy, metabolism, puberty, and many other essential functions. Scientists are studying PFAS because some of these chemicals may interfere with how hormone signals are sent, received, or processed. Rather than damagi...

In this episode, we explore what current scientific research says about how PFAS may affect the human body after exposure. Rather than focusing on fear, we focus on evidence. Scientists continue to study long-term patterns in large populations to better understand how these forever chemicals may influence important body systems over time. The goal is not to suggest that PFAS cause every illness, b...

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...
