Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals widely used in various industries for their resistance to heat, water, and oil. These substances have been incorporated into numerous products, including non-stick cookware, waterproof clothing, firefighting foams, and food packaging. Due to their persistent nature, PFAS are often referred to as "forever chemicals," as they do not easily break down in the environment or the human body. One of the most concerning issues with PFAS is their contamination of water sources, where they can accumulate over time and pose health risks. To address this, water treatment methods such as activated carbon filtration, ion exchange, and reverse osmosis can help remove PFAS from drinking water.
Where do PFAS come from?
PFAS originate from both industrial and consumer sources. They are produced in manufacturing facilities that create fluoropolymer coatings and products, such as Teflon and stain-resistant fabrics. These chemicals are also released into the environment through wastewater discharge, landfill seepage, and the use of firefighting foams, particularly around airports and military bases. As a result, PFAS contamination can be found in soil, air, and water sources worldwide.
What do PFAS do?
PFAS have unique chemical properties that make them highly resistant to degradation. They accumulate over time in the environment, leading to widespread contamination. In humans, PFAS can accumulate in the blood and tissues, where they remain for extended periods. Their persistence raises concerns about long-term exposure and potential health risks.
Are PFAS dangerous to humans?
Scientific research indicates that prolonged exposure to PFAS can have adverse health effects. Studies have linked PFAS exposure to various health conditions, including:
Increased cholesterol levels
Liver damage
Thyroid dysfunction
Immune system suppression
Hormonal disruption
Developmental issues in infants and children
Increased risk of certain cancers, such as kidney and testicular cancer
Because of these potential health risks, regulatory agencies are working to limit PFAS exposure and contamination levels in consumer products and drinking water.
How to remove PFAS
Eliminating PFAS from the environment and human exposure requires multiple strategies, including:
Regulatory Restrictions: Governments are implementing stricter regulations on PFAS production and use to reduce contamination.
Safer Alternatives: Scientists are developing alternative chemicals and materials that perform similar functions without the persistent risks associated with PFAS.
Proper Disposal and Waste Management: Industries and consumers must dispose of PFAS-containing products responsibly to prevent further environmental contamination.
How PFAS can be found in drinking water and how to remove them
Water contamination is one of the most significant concerns regarding PFAS. These chemicals can seep into groundwater, rivers, and lakes, making their way into drinking water supplies. Because they do not degrade easily, removing PFAS from water requires advanced treatment technologies, such as:
Activated Carbon Filtration: Granular activated carbon (GAC) can adsorb PFAS from water, effectively reducing contamination levels.
Ion Exchange Resins: Specially designed resins can trap PFAS ions, helping to purify water supplies.
Reverse Osmosis: This filtration method uses a semi-permeable membrane to remove PFAS and other contaminants from water.
Advanced Oxidation Processes: These involve chemical reactions that break down PFAS molecules, although this method is still under development.
Drinking water dispensers equipped with high-quality filters, such as those using activated carbon, ion exchange resins, or reverse osmosis, can effectively reduce PFAS levels in drinking water.
Borg & Overström drinking water dispensers and integrated tap systems are designed with a unique 5-step approach to create the cleanest water possible. This includes high performance carbon filtration. Our easy-fit carbon filters help to reduce sediment and bacteria and microplastics.
By using active carbon 0.5 micron filtration, unwanted PFAS can be addressed, leaving only great-tasting, healthier water that is safe to drink.
Are PFAS in drinking water found in tap and bottled water?
The simple answer is yes. Research has been done on sample water from taps and bottled water in various countries around the world, from the UK to China. The findings were that 99% of samples of bottled water contained PFAS.
Simple treatments can help to reduce the level of PFAS, practices such as boiling the water first and using filtration methods. This is why Borg & Overström drinking water dispensers and integrated tap systems offer such a safe, hygienic option.
Where does the law stand with PFAS in France?
In France, PFAS regulation is becoming stricter, with increasing government action to limit their environmental and health impacts. The country follows the EU Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) framework, which is working toward a broad PFAS ban, and has pushed for tighter restrictions at the European level. Nationally, the French water authorities monitor PFAS contamination, with limits set for drinking water quality. The government has introduced a ban on PFAS in certain consumer products like cosmetics and food packaging, ahead of wider EU restrictions. Additionally, environmental agencies are conducting large-scale investigations into PFAS pollution, particularly around industrial sites. Public pressure and media coverage have intensified, leading to legal actions against companies responsible for PFAS contamination. Despite resistance from industries that rely on PFAS, France continues to advocate for a phased-out approach, balancing environmental protection with economic considerations.
