“The Environmental Protection Agency reportedly has decided not to set legal limits for the toxic fluorinated chemicals PFOA and PFOS in drinking water. The news is deeply disturbing, because an estimated 110 million Americans’ water may be contaminated with those cancer-linked compounds or others in the chemical family known as PFAS.

But there is another group of Americans threatened by PFAS chemicals – and they haven’t yet been born.  

In 2005 and 2009, laboratory tests commissioned by Environmental Working Group, Commonweal and Rachel’s Network found PFOA, PFOS and other PFAS chemicals in the umbilical cord samples from 20 babies born in the U.S.

These tests exposed the shocking truth that American babies are born pre-polluted with PFAS and other toxic chemicals, which can pass from mothers to fetuses through the umbilical cord. According to the Centers for Disease Control and Prevention, nearly all Americans have PFOA or PFOS in their blood.

PFOA, once used to make DuPont’s Teflon, and PFOS, formerly an ingredient in 3M’s Scotchgard, have been linked through extensive research to cancer, kidney disease and weakened childhood immunity.

With the analytical capabilities of the time, the laboratory detected the presence of 10 different PFAS chemicals in the umbilical cord samples. On average, five PFAS compounds were in each sample, and two babies had nine PFAS chemicals in their cord blood.

Since then, multiple international studies have confirmed our findings. Most recently, in 2016 a Canadian study found PFAS chemicals in more than 90 percent of the nearly 2,000 cord blood samples collected from pregnant women.

Not long ago, scientists believed the placenta shielded umbilical cord blood – and the developing fetus – from environmental pollution. But EWG’s research and other studies show that during this critical time of development in the womb, the fetus is already exposed to scores of industrial chemicals.

Exposure to PFAS chemicals comes from many sources – not only drinking water but also food and food packaging, some brands of waterproof clothing and even cosmetics.The extent of drinking water and environmental contamination is only now coming to light, decades after widespread manufacturing of PFAS-containing materials and products. EWG research estimated that PFAS contaminants may be in the drinking water of 110 million Americans.

The list of PFAS chemicals that EWG tests could detect are just a small fraction of the thousands that have been in use worldwide. PFOA and PFOS are now banned in the U.S., and their levels in people have been dropping, according to CDC biomonitoring studies. Meanwhile, replacement PFAS chemicals have come on the market, such as the GenX chemical, which is about as toxic as PFOA.

In 2008, EWG first called attention to the fact that companies have been quietly substituting the older PFAS chemicals with replacements, on the basis of woefully inadequate health and safety information. Sharon Lerner of The Intercept reported that ‘203 [different] PFAS have been made in or imported to the U.S. in large quantities since 1986.’

Congress and the Trump administration should take steps to understand the sources of PFAS contamination, monitor the scope of PFAS contamination, stop the introduction of new PFAS chemicals, and set science-based cleanup standards for contaminated sites. Specifically, policymakers should:

  • Add PFAS chemicals to the Toxic Release Inventory and require monitoring of PFAS in air, water and our children’s bodies.
  • Ban the introduction of new PFAS chemicals and end the use of PFAS in firefighting foams and in consumer products like cookware, food packaging and personal care products.
  • Set tough science-based cleanup standards, require water utilities and military installations to meet them, and make sure polluters pay their fair share of the cost…”
