Practical guide to getting rid of forever chemicals (PFAS) from your tap water
Tap water contains *eternal pollutants* like PFAS, threatening your long-term health. These substances, used since the 1940s, daily penetrate our environment. Being aware of their presence is fundamental to preserving your well-being.
Effective filtration methods reveal accessible solutions to reduce the presence of PFAS. Reverse osmosis and nanofiltration technologies stand out for their notable efficiency.
Modernizing water treatment plants is a crucial challenge, while the necessary investments are colossal.
Preferring filtered water enhances your protection against these unwanted pollutants, ensuring healthier consumption. Assessing your options is an integral part of a proactive approach to water resource contamination.

PFAS: A scourge for drinking water
Per- and polyfluoroalkyl substances, or PFAS, excel in manufacturing persistent chemicals. Since the 1940s, these toxic compounds have infiltrated daily life, finding refuge in various consumer items. Food packaging, textiles, and even cosmetics contain these eternal pollutants. Their name evokes their longevity, capable of defying time by contaminating our environment and our health.
The dangers of PFAS to health
Many studies highlight the harmful effects of PFAS on human health. Prolonged exposure to these substances can lead to various problems, ranging from chronic diseases to hormonal disruptions. The Agency for Toxic Substances and Disease Registry (ATSDR) emphasizes that drinking water represents a major source of exposure to these substances. The need to eliminate them from water becomes imperative.
Solutions to purify your drinking water
Reverse osmosis and nanofiltration
Choosing a reverse osmosis system proves to be an effective method for purifying drinking water. This process relies on a membrane that filters contaminants, particularly PFAS, allowing only pure water to pass through. Alfred Bernard, emeritus professor at UCLouvain, validates the effectiveness of this approach, capable of isolating numerous pollutants, including PFAS. A highly sought solution to ensure quality water within your home.
Filter pitchers: An accessible alternative
Filter pitchers present themselves as a cost-effective solution to reduce the presence of PFAS in water. However, their effectiveness varies from model to model. Some pitchers, such as Zerowater and Clearlyfiltered, manage to eliminate more than 96% of contaminants, while others, like those equipped with a Brita Elite filter, offer mixed performance, not exceeding 48% removal.
Modernization of water treatment infrastructure
Updating water treatment plants is a major challenge for eliminating PFAS at the source. These modifications require significant investment and substantial energy. For example, the Syndicat des Eaux d’Île-de-France plans to spend more than one billion euros to integrate suitable filtration systems. Meanwhile, these new installations would lead to a significant increase in energy consumption.
Waste management: A challenge to tackle
The crucial question that arises is about the disposal of PFAS once filtered. Remaining aware of this aspect is essential, as these substances must not be released into the environment. The need for proper management of these chemical wastes is becoming increasingly urgent in view of the accumulation of eternal pollutants. Protecting the water we consume requires taking effective action against this scourge.
Frequently asked questions
What are PFAS?
PFAS, or per- and polyfluoroalkyl substances, are a family of more than 15,000 chemicals known for their persistence in the environment, often called “eternal pollutants” due to their ability to remain in water and soil for decades.
How do PFAS end up in our drinking water?
PFAS can contaminate drinking water through various means, including industrial effluents, waste disposal sites, and failing filtration systems. Tap water is often considered one of the main sources of human exposure to these substances.
What methods are effective in removing PFAS from tap water?
Reverse osmosis and nanofiltration are among the best methods for reducing PFAS. Filter pitchers can also be effective, but their capacity depends on their design and the types of targeted contaminants.
Is reverse osmosis effective against PFAS?
Yes, the reverse osmosis system uses a special membrane that effectively filters PFAS, including both long and short chain, while allowing purified water to pass through.
Are all water filters effective against PFAS?
No, not all water filters are equal. Some filter pitchers can eliminate more than 96% of PFAS, while others filter only 20 to 48%. It is crucial to check the specifications of each model.
What if water treatment plants cannot eliminate PFAS?
It is essential to treat drinking water at the source with modern filtration systems. However, this requires significant investments. Consumers can also opt for domestic solutions such as reverse osmosis systems or suitable filter pitchers.
What are the health risks of prolonged exposure to PFAS?
PFAS are associated with various health problems, including hormonal disorders, heart diseases, and reduced immune response. Prolonged exposure may also increase the risk of certain cancers.
How can I know if my water is contaminated with PFAS?
It is recommended to test tap water if you suspect contamination. Specialized laboratories offer analyses to detect the presence of PFAS and other contaminants.
What is the best option: buying bottled water or using a filter?
Using a suitable filter is often more economical and sustainable than constantly buying bottled water. Make sure to choose a filter known for its effectiveness in removing PFAS.
Can PFAS be eliminated after being filtered?
It is important to properly dispose of filters containing PFAS, as their release into the environment can cause pollution issues. Specific procedures must be followed to manage these contaminations.
