PFAS: understand, act and protect – Solutions for municipals and industrials

PFAS (per- and polyfluoroalkyl substances) are known as "forever chemicals". Widely used since the 1950s in a multitude of industrial applications but also in a wide variety of everday consummer products, they are found in water, air, and soil. They are extremely persistent and accumulate both in the environment and in living organisms.

The issues related to PFAS are numerous and complex. These substances are associated with many adverse health effects, such as hormonal disorders, cancers, and damage to the immune system.

Given their harmful effects on human health and ecosystems, it is essential to take action.

What are PFAS? Definition and origins

PFAS (per- and polyfluoroalkyl substances) are a group of over 10,000 synthetic chemical compounds used since the 1950s. They are commonly found in:

  • Firefighting foamsWaterproof textiles
  • Non-stick
  • cookware
  • Food packaging
  • CosmeticsAt the molecular level, PFAS contain a highly stable carbon-fluorine bond, making them extremely persistent in the environment and nearly impossible to break down naturally. This is why they are often referred to as “forever chemicals.”

Why are PFAS so concerning?

PFAS pose several major risks:

  • Environmental: They contaminate water, soil, air, and ecosystems—even in polar regions.
  • Human health: Some PFAS are linked to cancer, endocrine disruption, immune system issues, and fertility problems.
  • Bioaccumulation: They build up in living organisms and spread throughout the food chain.

European and French regulations: thresholds to meet by 2026

The European Directive 2020/2184, transposed into French law by the decree of December 30, 2022, mandates:

  • A limit of 100 ng/L (0.1 µg/L) for the sum of 20 PFAS in drinking water (EDCH).
  • Stricter thresholds for other micropollutants: bisphenol A, chlorates, uranium, pesticide metabolites.
  • Mandatory monitoring starting January 1, 2026, as part of the national sanitary control program.
  • For industries, specific restrictions on aqueous discharges under the ICPE (Classified Installations for Environmental Protection) framework.

Your challenges

Communities and industries across Europe are increasingly facing the challenge of PFAS contamination in their drinking water and wastewater. Addressing this issue requires a clear understanding of four key areas: detection and monitoring, regulatory compliance, treatment and removal, and transparent risk communication. Each plays a vital role in protecting public health.

Municipalities

  • Must be compliant by 2026.
  • Need to invest in adapting or upgrading treatment infrastructure.
  • Face increasing public and media pressure.
  • Risk financial penalties in case of pollution.
  • Are responsible for public health and maintaining user trust.

Industries

  • Brand image can be severely damaged in the event of contamination.
  • Polluter-pays principle increases their legal liability.
  • Remediation costs can be high.
  • Operational shutdowns or legal disputes may occur in case of non-compliance.
