Forever Chemicals
In Your Water
PFAS never break down. They accumulate in your blood, organs, and drinking water — and 49% of U.S. tap water is contaminated. Here's what you need to know.
What Are PFAS and Why Are They Called "Forever Chemicals"?
Per- and polyfluoroalkyl substances (PFAS) are a family of over 12,000 synthetic chemicals that share one defining trait: an extraordinarily strong carbon-fluorine bond that makes them virtually indestructible. No natural process — sunlight, water, bacteria, or heat — can break them down.
Invented in 1938 and mass-produced since the 1950s, PFAS have been used in nonstick cookware (Teflon), waterproof clothing (Gore-Tex), food packaging, firefighting foam (AFFF), and thousands of industrial applications. They've since contaminated soil, groundwater, and drinking water supplies worldwide.
Once ingested, PFAS accumulate in your blood, liver, and kidneys with a half-life of 4–8 years. This means your body eliminates only half of its PFAS burden every 4–8 years — while you continue to ingest more daily from water, food, and consumer products.
The Carbon-Fluorine Bond: Why PFAS Last Forever
The carbon-fluorine (C-F) bond is the strongest single bond in organic chemistry — requiring 485 kJ/mol to break. For comparison, carbon-hydrogen bonds require only 411 kJ/mol. This exceptional stability is what makes PFAS useful in industry (nothing sticks to them) and devastating in the environment (nothing destroys them).

Key PFAS Compounds in Drinking Water
Not all PFAS are created equal. These are the most commonly detected compounds in U.S. drinking water, each with different regulatory limits, persistence, and health effects.
PFOA (Perfluorooctanoic Acid)
Also known as: C8
Phased out by 2015, but persistent in environment
PFOS (Perfluorooctane Sulfonic Acid)
Also known as: Scotchgard chemical
Phased out by 3M in 2002, still widespread
GenX (HFPO-DA)
Also known as: PFOA replacement
Currently in use as 'safer' alternative
PFBS (Perfluorobutane Sulfonic Acid)
Also known as: Short-chain PFAS
Increasingly used as PFOS replacement
PFHxS (Perfluorohexane Sulfonic Acid)
Also known as: Medium-chain PFAS
Banned under Stockholm Convention 2022
PFNA (Perfluorononanoic Acid)
Also known as: Long-chain PFAS
Still detected in drinking water nationwide
How PFAS Affect Your Health
Decades of research — including the landmark C8 Science Panel study of 70,000 exposed residents — have established clear links between PFAS exposure and serious health conditions.
Cancer
- Kidney cancer — 2x increased risk with PFOA exposure (C8 Science Panel)
- Testicular cancer — significant association with occupational PFOA exposure
- Bladder cancer — emerging evidence from PFOS studies
- Thyroid cancer — dose-dependent relationship observed
Immune System
- Reduced vaccine antibody response in children (40–50% reduction)
- Decreased immune cell counts and function
- Increased susceptibility to infections
- Potential link to autoimmune disorders
Reproductive & Developmental
- Reduced birth weight in exposed mothers
- Pregnancy-induced hypertension and preeclampsia
- Decreased fertility in both men and women
- Developmental delays in exposed children
Endocrine & Metabolic
- Thyroid hormone disruption (hypothyroidism)
- Elevated cholesterol levels (10–20 mg/dL increase per unit PFOA)
- Liver damage and elevated liver enzymes
- Ulcerative colitis — 2x increased risk
Key Finding: The C8 Science Panel (2005–2012) studied 70,000 residents exposed to PFOA-contaminated water near DuPont's West Virginia plant. They established "probable links" between PFOA exposure and kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, pregnancy-induced hypertension, and high cholesterol.

How We Detect PFAS in Your Water
Our certified lab partner uses EPA-approved analytical methods to detect PFAS at parts-per-trillion concentrations — far below what home test kits can measure.
EPA Method 537.1
Liquid chromatography/tandem mass spectrometry (LC-MS/MS) for 18 PFAS compounds in drinking water. The gold standard for regulatory compliance testing.
EPA Method 533
Complementary to 537.1, covering short-chain and newer PFAS compounds not included in 537.1, including GenX and PFBS.
Total Oxidizable Precursor (TOP) Assay
Converts PFAS precursors to measurable terminal PFAS, revealing total PFAS burden including unidentified compounds.
What Your $99 Test Reveals About PFAS
Don't Wait for Your Utility to Test for PFAS
The EPA's new PFAS rules don't require full compliance until 2029. That's 5 more years of exposure. Our $99 test tells you what's in your water today — and what to do about it.
