Who Knew We Painted with PFAS?

According to US Environmental Protection Agency (EPA), PFAS are widely used, long lasting chemicals, components of which break down very slowly over time. Because of their widespread use and their persistence in the environment, many PFAS are found in the blood of people and animals all over the world and are present at low levels in a variety of food products and in the environment. PFAS are found in water, air, fish, and soil at locations across the nation and the globe. Scientific studies have shown that exposure to some PFAS in the environment may be linked to harmful health effects in humans and animals.

In 2026, Daqian Jiang and his colleagues has created a model that has quantified PFAS retention and emissions associated with paints in the US starting from 2000 with projections up to 2060…Results revealed that in 2020, around 565 tonnes of PFAS were stored in in-use paint in the US…. By 2060, the model predicted that around 486 tonnes of these retained PFAS would accumulate in landfill sites, emitting 25 times more PFAS into the environment than in 2020, with hotspots driven by demolition activity and waste routing. ‘So even if PFAS use in paints were reduced or phased out today, substantial future emissions could still occur from the large quantities already present in existing buildings.’

The Essence of a Nightmare: PFAS on Ocean Waves

PFAS, or forever chemicals, are ubiquitous in our environment. In the U.S. alone, there are more than 57,000 sites contaminated with these chemicals. They’re in our drinking water, our soil, our products—and our ocean. And according to new research, when waves crash onto shores around the world, they spray hundreds of thousands of PFAS particles into the air, creating a cycle in which these chemicals go from land to sea and back again. PFAS (per- and polyfluoroalkyl substances) are a class of synthetic chemicals largely used to make products stain-, grease-, and water-resistant. They’ve been dubbed “forever chemicals” because they don’t easily break down and so stay in our environments for thousands of years. They’re linked to harmful effects to health, including cancer, decreased fertility, developmental delays, and more.

From Miracles to Pariahs: Forever Chemicals

Leave a reply

The US Environmental Protection Agency (EPA) in March 2023 proposed the first federal limits on so-called forever chemicals in public drinking water…The EPA is proposing maximum allowable levels for two compounds in a class of chemicals known as perfluoroalkyl and polyfluoroalkyl substances, or PFAS. Known as forever chemicals because they take a long time to break down, they were used for decades in carpeting, clothing, food packaging, firefighting foam and other consumer and industrial products…Once prized as innovative substances that could resist stains, water, grease and heat, PFAS are increasingly viewed as a threat because they persist in the environment and have been found in roughly 99% of the U.S. population…

The move represents a seismic shift in the regulation of the nation’s drinking water, and will require sweeping changes for thousands of water systems that will have to test for and treat a group of chemicals that have been the subject of growing concern among public health officials and people worried about the safety of water coming from their taps.  In its new proposed rule, EPA set a limit for two types of PFAS of 4 parts per trillion each in public drinking-water systems. The EPA also said it would regulate four other PFAS chemicals by requiring treatment if the combined level reaches a certain concentration….The rule, if enacted, is likely to fuel fights over who will bear most of the cost for treatment systems in hundreds of communities. Water companies, states and communities have already filed thousands of lawsuits against companies that manufactured or used PFAS, seeking to recover costs for cleanups and filtration.

The two individual chemicals that the EPA is proposing limiting are known as PFOA and PFOS. Companies phased out their production over the past two decades, but the long-term use of firefighting foam containing them at military facilities and airports is a frequent source of drinking-water contamination, according to the EPA. The chemicals and other PFAS have also tainted water after escaping from landfills, wastewater-treatment plants and textile and other manufacturers.

Scientific understanding about the health risks from PFAS is still evolving, but a number of studies have shown links to a variety of cancers, thyroid disease, high cholesterol and other issues. There are thousands of PFAS chemicals, including roughly 700 that have been used in commerce in the U.S. in recent years, according to the EPA…
