Water news: PFAS and their regulation

Since the beginning of 2023, water news, for example, a new standard requires that drinking water comply with a maximum concentration of 0.1 μg/L for the sum of 20 PFAS compounds. This directive was adopted by the European Union. This news marks an important milestone in the regulation of chemical pollutants related to water quality.

What are PFAS?

"Per- and polyfluoroalkyl substances," or PFAS, comprise more than 4,000 chemical substances. These compounds are widely used in industry and agriculture. Furthermore, they are also found in everyday products: non-stick cookware, waterproof textiles, paper or cardboard food packaging, and cosmetic products.

Their use also extends to other sectors. Indeed, they are present in fire-fighting foams, lubricants, and electrical insulation. Their massive release into the environment makes them ubiquitous. They are found in the air, soil, and groundwater. This leads to their contamination of food and drinking water, creating a major problem.

Why are PFAS called "forever pollutants" in water news?

PFAS are nicknamed "forever pollutants" because of their exceptional resistance to degradation. Once released during their manufacture or use, they migrate into water. They remain there intact for long periods, sometimes decades.

They are found in oceans, groundwater tables, and drinking water. This situation makes their elimination complex. Although progress is underway thanks to research, these pollutants remain difficult to treat. They therefore pose a significant environmental challenge.

What are the obligations for tap water?

Regulation requires a rapid response to any exceedance of the 0.1 μg/L standard for PFAS. Each case must be addressed to restore compliance. As of January 2026, health inspections by Regional Health Agencies will systematically include testing for these substances in drinking water. This measure aims to strengthen health security and protect consumers.

What solutions are there to eliminate PFAS?

Water companies conduct analyses to detect PFAS in water resources. These campaigns make it possible to inform the public and identify exceedances. Several technologies are available to treat these pollutants.

• Activated carbon captures certain types of PFAS.
• Advanced membrane processes, such as low-pressure reverse osmosis, retain a wide range of compounds.
• Combined solutions associate several techniques for greater efficiency.
• The Filtrahome Box is an innovative solution dedicated to professionals and crisis situations.

These initiatives contribute to guaranteeing quality drinking water. They play a key role in protecting public health and managing water news in France.
