At least 45% of tap water contaminated

At least 45% of the United State's tap water could be contaminated with at least one form of PFAS, known as "forever chemicals," according to a study from the U.S. Geological Survey.

What are ‘forever chemicals’?

PFAS are a large family of human-made chemicals known as ‘forever chemicals’ because they don’t break down in the environment. This has led to widespread contamination and bad effects on our health.

 

Where can we find PFAS?

Manufacturers use PFAS to make products resistant to oil, heat, stain, or water. They are found in everything from cosmetics, to outdoor gear, non-stick pans, food wrappers, and countless others, according to the CDC, and so end up in our food, water, and air.

PFAS are even in our blood

One study found that 97% of Americans have measurable levels of PFAS in their blood. For years, experts have said the most common way to be exposed to PFAS is through drinking water.

‘Forever chemicals’ in rainwater everywhere

Research conducted by the University of Stockholm, revealed that rainwater almost everywhere on Earth has unsafe levels of forever chemicals’.

Even in Antartica

The Per- and poly-fluoroalkyl substances (PFAS) in rainwater are even present in Antarctica, the researchers said.

Rainwater everywhere judged unsafe to drink

“Based on the latest U.S. guidelines for PFOA in drinking water, rainwater everywhere would be judged unsafe to drink”,, said Ian Cousins, lead author of the study on rainwater, to the BBC.

Many people around the world rely on rainwater

“Although in the industrial world we don't often drink rainwater, many people around the world expect it to be safe to drink, and it supplies many of our drinking water sources”, Cousins added.

Rainwater is also essential for agriculture

Furthermore, agriculture around the world depends on rainfall, and everything we eat demands water.

Uncertain health effects

Human health effects from exposure to low environmental levels of PFAS are uncertain, according the CDC. Some scientists even say that there is no link between PFAS and health problems.

Higher risk of cancer

However, The Agency for Toxic Substances and Disease Registry says exposure to PFAS may lead to higher risk for kidney or testicular cancer, increased cholesterol levels, and damage to the liver and immune system.

Forever chemicals linked to infertility

Moreover, a recent study conducted in Singapore, showed that women with higher levels of “forever chemicals” in their blood have a 40% lower chance of becoming pregnant within a year of trying to conceive, several media reported.

Experts have called for new limits on PFAS

Experts have been calling for new limits on PFAS for years, and studies like these regularly renew calls to do so.

Some benefit economically while polluting water

“It cannot be that some few benefit economically while polluting the drinking water for millions of others, and causing serious health problems”, Dr. Jane Muncke, managing director of the Food Packing Foundation in Zurich, told Euro News.

Polluting industries have to step up

“The vast amounts that it will cost to reduce PFAS in drinking water to levels that are safe, based on current scientific understanding, need to be paid by the industry producing and using these toxic chemicals”, said Muncke.

A failed bill to remove PFAS in cosmetics

In June 2021, a bipartisan group of senators introduced the “No PFAS in Cosmetics Act” to ban the use of PFAS in cosmetics and personal-care items. The bill failed to move to the committee.

A lot of companies have stopped using PFAS

However, plenty of companies have pledged to stop using PFAS in their products, including some clothing, fast food, and outdoor sports brands. The Green Science Policy institute put together a list of brands of products that are PFAS-free that is available online.

A method for decomposing ‘forever chemicals’

Luckily, scientists recently found a method for decomposing ‘forever chemicals’, a major breakthrough in addressing widespread environmental contamination across the world, according to research published in 'Science.'.

Low temperature technique to break down PFAS

An emerging low temperature technique to break down PFAS has proven to be very effective“The fundamental knowledge of how PFAS degrade is the single most important thing coming out of this study,” said Will Dichtel, researcher and co-author of the new study.

How to limit our exposure to ‘forever chemicals’?

But until scientists actually apply the new method to get rid of ‘forever chemicals’, a good way to limit our exposure to them is by buying PFAS-free products when we need to replace our own.
