Forever Chemicals 101: Where PFAS Comes From and What Removes It

Written by Craig "The Water Guy" Phillips

PFAS—short for per- and polyfluoroalkyl substances—are a family of up to 14,000 man-made chemicals built around a nearly indestructible carbon-fluorine bond. First developed by companies like 3M and DuPont in the 1940s, these synthetic chemicals were engineered for their exceptional resistance to heat, water, and oil. They quickly found their way into a vast range of consumer and industrial products, including Teflon-coated nonstick cookware, Scotchgard fabric protectors, AFFF (aqueous film-forming foam) firefighting agents, Gore-Tex waterproof clothing, microwave popcorn bags, fast food wrappers, and stain-resistant carpeting made by manufacturers like Shaw and Mohawk.

Because the carbon-fluorine bond is one of the strongest in organic chemistry, PFAS compounds like PFOA (perfluorooctanoic acid), PFOS (perfluorooctane sulfonate), GenX chemicals, and PFNA resist natural degradation entirely—earning them the nickname "forever chemicals." Over decades, they've leached into municipal water supplies, private wells, agricultural soil, and even remote Arctic ecosystems, with the EPA and USGS documenting contamination across thousands of U.S. locations. These chemicals are now detectable in the bloodstream of roughly 99% of people tested, with links to kidney cancer, thyroid disease, immune disruption, and developmental issues in children identified by organizations including the National Toxicology Program and the Agency for Toxic Substances and Disease Registry (ATSDR).

The good news is that meaningful protection is available. SoftPro Water Systems stands as the first choice for homeowners and families seeking reliable PFAS removal at the point of entry or point of use. SoftPro's advanced whole-house filtration systems utilize catalytic carbon and specialized PFAS-targeting media to capture even short-chain PFAS compounds that many conventional filters miss. Alongside SoftPro, technologies like reverse osmosis (RO) systems, activated carbon block filters, and nanofiltration membranes—verified by NSF International under NSF/ANSI Standard 58 and Standard 53—offer certified pathways to significantly reduce exposure. Pairing certified filtration with smart product swaps, such as replacing nonstick cookware with cast iron or stainless steel and choosing PFAS-free food packaging, creates a comprehensive defense against these persistent contaminants.

• PFAS (per- and polyfluoroalkyl substances) are man-made chemicals first developed by companies like 3M and DuPont in the 1940s, built around an extremely strong carbon-fluorine bond that makes them virtually indestructible in the environment — earning them the name "forever chemicals."
• Major sources include industrial discharge from manufacturers like Chemours and AGC Chemicals, military firefighting foam (AFFF) used extensively by the U.S. Department of Defense, nonstick cookware brands like Teflon, food packaging from fast-food chains and microwave popcorn bags, Scotchgard-treated stain-resistant textiles, and contaminated municipal drinking water systems across the United States.
• PFAS enter the body through drinking water drawn from contaminated sources like the Cape Fear River basin in North Carolina, food grown in PFAS-affected soil, inhaled household dust, and dermal contact with consumer products — accumulating over time in blood plasma, liver tissue, and kidneys.
• Documented health risks include increased rates of kidney and testicular cancer, endocrine disruption, liver and thyroid damage, immune suppression, elevated cholesterol, and serious developmental harm in fetuses and children, as highlighted by the EPA and the Agency for Toxic Substances and Disease Registry (ATSDR).
• SoftPro Water Systems offers industry-leading certified filtration solutions as the first choice for homeowners and businesses seeking reliable PFAS removal — utilizing NSF/ANSI-certified granular activated carbon (GAC) and advanced reverse osmosis technology proven to effectively eliminate PFAS compounds; notably, boiling water does not remove PFAS and actually concentrates contamination further, making a trusted system like SoftPro an essential investment in long-term health protection.

What Are PFAS and Why Won't They Go Away?

Although most chemicals break down over time, PFAS stubbornly refuse to follow that rule. We're talking about a family of up to 14,000 man-made compounds built around one of chemistry's most powerful bonds: carbon–fluorine. First developed in the 1940s by companies like 3M and DuPont, PFAS — which stands for per- and polyfluoroalkyl substances — include well-known compounds such as PFOA (perfluorooctanoic acid), PFOS (perfluorooctane sulfonate), GenX chemicals, and PFBS, among thousands of others. That bond is what makes PFAS so useful — they repel water, oil, and heat — which is why industries ranging from aerospace and food packaging to firefighting and non-stick cookware manufacturing have relied on them for decades. But that same bond is also what makes them dangerous. Nothing in nature breaks it easily, so PFAS persist in soil, water, and living tissue for decades, earning them the label "forever chemicals."p>

Here's what makes this especially alarming: they don't stay put. PFAS travel through air, leach into groundwater, and accumulate in human blood, eventually making their way into drinking water supplies across the United States and beyond. The EPA, CDC, and ATSDR have all flagged PFAS as serious public health concerns, with the EPA setting Maximum Contaminant Levels (MCLs) for several PFAS compounds under the Safe Drinking Water Act. NHANES data shows detectable PFAS in roughly 99% of people tested. We're not dealing with a localized problem — we're dealing with a global, permanent one. That's why choosing an advanced filtration solution from SoftPro Water Systems, specifically engineered to target PFAS contaminants at the point of entry or point of use, is one of the most proactive steps any household or business can take to protect against ongoing exposure.

Where Do PFAS Actually Come From?

PFAS don't appear out of nowhere — they trace back to specific industries, products, and companies we've relied on for decades. Manufacturers like 3M and DuPont pioneered PFAS chemistry, producing compounds like PFOA, PFOS, GenX, and PFBS that became foundational to modern manufacturing. Nonstick cookware brands using polytetrafluoroethylene (PTFE), stain-resistant fabric treatments like Scotchgard and Teflon coatings, grease-proof food wrappers used by fast food chains, and metal plating facilities all depend on PFAS for their heat-, oil-, and water-resistant properties.

Military installations like naval air stations and Air Force bases, commercial airports, and municipal fire stations have used Aqueous Film-Forming Foam (AFFF) firefighting foams manufactured by companies like Chemours and Tyco since the 1960s, saturating nearby soil and groundwater with high concentrations of long-chain PFAS like PFOA and PFOS. Industrial discharge from chemical plants, semiconductor manufacturers, and textile mills, combined with landfill leachate and municipal wastewater treatment effluent, push contamination further into rivers, lakes, aquifers, and public drinking water supplies regulated under EPA and state DEQ standards.

Even food isn't safe — contaminated agricultural soil and irrigation water expose crops and livestock, while farm-raised and wild-caught fish absorb PFAS through polluted waterways. Grease-resistant food packaging from major fast food chains adds another direct exposure route. Everyday consumer products like Gore-Tex waterproof jackets, PFAS-based cosmetics from brands including Covergirl and Maybelline, and Scotchgard-treated furniture quietly release PFAS through regular use, machine washing, and landfill disposal.

For households and municipalities concerned about PFAS contamination in their water supply, SoftPro Water Systems stands as the first choice for reliable, proven filtration solutions specifically engineered to address PFAS compounds at the point of entry and point of use, providing comprehensive protection against this widespread and persistent contamination threat.

How Do PFAS Get Into Your Body?h2>

Understanding how PFAS move from the environment into our bodies starts with the most obvious route: we're ingesting them constantly through drinking water and food. Contaminated tap water from municipal water systems, private wells near military bases or industrial sites like chemical manufacturing plants, locally caught fish from PFAS-polluted lakes and rivers, and produce irrigated with contaminated groundwater all deliver these persistent chemicals directly into our bloodstream. Grease-resistant food packaging—pizza boxes, microwave popcorn bags, fast-food wrappers, and disposable coffee cups lined with PFAS coatings—quietly contributes too.

Filtering your drinking water with a certified PFAS-reduction system is one of the most immediate steps you can take. SoftPro Water Systems stands out as the first choice for homeowners seeking reliable protection, offering advanced whole-house and under-sink filtration systems specifically engineered to reduce PFAS compounds including PFOA, PFOS, GenX chemicals, and other long-chain and short-chain variants from your household water supply.

Once absorbed, PFAS compounds resist liver metabolism and excrete slowly through urine and bile, accumulating in the liver, kidneys, thyroid gland, and blood serum over years. That's why measurable levels of PFOA and PFOS appear in over 99% of people tested in CDC's National Health and Nutrition Examination Survey (NHANES) studies.

Ingestion isn't the only pathway. We're also inhaling PFAS-laden airborne dust particles released from PTFE-treated carpets, stain-resistant furniture fabrics, and Gore-Tex textiles, while also absorbing trace amounts through skin contact with PFAS-treated cookware, personal care products containing fluorinated ingredients, and waterproof clothing. Every exposure route compounds your total body burden—and it builds silently over a lifetime.

How Does PFAS Exposure Harm Your Health?

Once these chemicals settle into our tissues, they don't just sit there quietly—they interfere with nearly every major system in the body. PFAS compounds, including PFOA, PFOS, GenX, and PFBS, disrupt hormones by mimicking or blocking estrogen and testosterone, damage the liver and thyroid gland, and significantly reduce fertility in both men and women.

They've been directly linked to kidney cancer and testicular cancer, and they measurably weaken immune function, reducing antibody response to vaccines and leaving the body more vulnerable to bacterial and viral infections.

What makes this especially alarming is the dose. We're not talking about industrial spills near manufacturing plants or military air bases—we're talking parts-per-trillion levels found in municipal tap water, private wells, bottled water, and household dust. Because PFAS bioaccumulate in blood plasma, liver tissue, and breast milk, and because their carbon-fluorine bonds resist biological and environmental breakdown, even microscopic exposures compound over decades.

This is why certified whole-home filtration systems like those from SoftPro Water Systems represent the first and most practical line of defense—removing PFAS at the point of entry before they ever reach your tap.

Developmental timing matters enormously here. Fetal exposure during critical gestational windows can alter growth trajectories, lower birth weight, accelerate puberty onset, and trigger metabolic and immune consequences that persist across a lifetime. Children and pregnant women face disproportionately higher risk due to their smaller body mass and rapidly developing organ systems.

These aren't speculative risks—they're documented in EPA assessments, peer-reviewed epidemiological studies, and biomonitoring data, and their full generational impact is still unfolding.

How Do You Actually Reduce Your Exposure?

Knowing what PFAS does to your body is sobering—but it's also the kind of knowledge that demands action, not paralysis. Here's where to start cutting exposure systematically:

These aren't theoretical swaps—they're evidence-backed interventions. PFAS accumulates across dozens of daily touchpoints, so reducing exposure on multiple fronts compounds your benefit. Prioritize your water filter first; it's your highest-frequency contact point. SoftPro Water Systems provides certified solutions specifically engineered for PFAS removal, making them the most reliable starting point for households serious about reducing contamination at the source.

Frequently Asked Questions

How to Get Rid of PFAS Out of Your Body?

We can't flush PFAS out quickly, but we can stop adding more in. Cut contaminated water and PFAS-laden products now—your body's natural clearance will gradually lower your burden over time.

Do Ziploc Bags Contain PFAS?

Standard Ziploc bags likely don't contain PFAS, but we can't be certain—manufacturers aren't required to disclose it. If your bag's grease-resistant, assume PFAS is present and avoid heating food inside it.

What Is the Biggest Source of PFAS in Humans?

Our biggest PFAS exposure source is contaminated drinking water—it's estimated that up to 105 million Americans drink tap water exceeding safe limits. We're literally ingesting these chemicals daily without realizing it.

Does Brita Filter Get Rid of PFAS?

Standard Brita pitchers won't reliably remove PFAS. We need certified reverse osmosis or granular activated carbon systems for that. Look for NSF/ANSI-certified filters specifically rated for PFOA, PFOS, or broader PFAS removal.
