Belgium Faces Human Rights Complaint Over PFAS Inaction

Environmental law NGO ClientEarth has filed a formal human rights complaint against Belgium with the European Committee of Social Rights (ECSR), accusing the Belgian state of systematically failing to protect its population from widespread PFAS pollution. The complaint, lodged on 8 July 2026, argues that Belgium violated Article 11 of the European Social Charter — the right to protection of health — by failing to take timely and adequate action despite knowing about the contamination for years.

The Scope of Belgium’s PFAS Crisis

Belgium has the highest known PFAS contamination levels in Europe, according to the Forever Pollution Project, a cross-border investigative journalism consortium. Per- and polyfluoroalkyl substances, known as “forever chemicals,” are a family of over 10,000 synthetic chemicals used since the 1940s for their non-stick, waterproof, and heat-resistant properties. They do not break down in the environment and accumulate in living organisms.

Contamination spans all three of Belgium’s regions. The most well-known hotspot is the 3M factory in Zwijndrecht, Flanders, where PFAS were produced from the 1970s until 2024. As early as 2001, PFOS concentrations in groundwater around the site were thousands of times above safe limits. Residents have been advised since 2021 not to eat garden produce or use groundwater.

In Wallonia, the US military base at Chièvres saw tap water PFAS levels five times the EU safety limit between 2021 and 2023, yet authorities never informed the public — even though the US Army had instructed personnel not to drink tap water there as early as 2017. The TotalEnergies plastics site at Feluy has also been identified as a major contamination source. In Brussels, the former Sicli fire extinguisher factory in Uccle is a significant hotspot, and water provider Vivaqua has systematically detected TFA — a persistent PFAS — in reservoirs supplying the capital at levels exceeding upcoming EU limits.

A Pattern of Systematic Failure

ClientEarth argues that Belgium’s failure is not isolated but systematic. According to the complaint, authorities knew about the contamination for years or even decades before acting, and action only came after investigative journalism by Flemish broadcaster VRT in 2021 and subsequent public pressure. Responses have been fragmented across Belgium’s three regions, measures have focused on hotspots rather than widespread pollution, and authorities have relied on further studies rather than concrete action.

In 2024, a Brussels court ruled that Flemish authorities failed to act as a “normal, diligent government,” despite knowing about the contamination for years. The complaint also notes that Bart De Wever, then-mayor of Antwerp and now Belgian Prime Minister, was allegedly informed of the PFAS situation as early as 2017.

Human Toll: Voices from Affected Communities

Toon Penen, a resident of Zwijndrecht living near the 3M plant, provided testimony for the complaint. “For a long time, I had no idea that I was living in one of the worst PFAS pollution sites in Europe,” he said. “I trusted that if there was a serious risk, the authorities would tell us clearly and in time. They did not.”

“The pollution has changed how I feel about my own home,” Penen added. “A garden should be a place where you can relax, grow food, let children play and let your dog run around without thinking about danger. But that feeling is gone.”

Health Impacts of PFAS Exposure

Exposure to PFAS is associated with at least a dozen diseases, including kidney, testicular, ovarian, prostate, and thyroid cancers; liver disease; obesity; Type 2 diabetes; reduced fertility; and immune system suppression. The World Health Organization classified PFOA as carcinogenic to humans in 2023.

Prof. Dr. Jacob de Boer, Emeritus Professor in Environmental Chemistry and Toxicology, explained: “PFAS do not break down and instead steadily accumulate in the human body — with severe associated health impacts such as immune system suppression, thyroid disruption, and even cancer when levels are high.”

Legal Strategy and Government Response

ClientEarth chose the ECSR because it “disposes of a very significant coercive power.” While the committee cannot impose fines, its findings carry significant political and legal weight and have led to major policy changes in member states. The Committee is expected to decide on the admissibility of the complaint in 2027, with a final decision expected within two to three years.

Belgian authorities acknowledge the seriousness of the contamination but push back against claims of complete inaction. A spokesperson for Federal Climate Minister Jean-Luc Crucke told The Brussels Times that a federal PFAS strategy has been presented and approved, adding: “Yes, Belgium is facing serious contamination… Yes, the public response still needs to be strengthened. But no, it is not accurate to say that nothing is being done.”

What’s Next

ClientEarth lawyer Hélène Duguy stated: “The solution is simple: the Belgian government needs to step up urgently and ban all PFAS as soon as possible. Alternatives exist. People’s health and human rights are on the line.”

The complaint demands a ban on all non-essential PFAS uses, systematic biomonitoring, remediation of contaminated sites, and better public information. A study published on 6 July 2026 found that even 100 billion euros per year in remediation efforts across Europe would only remove a tiny fraction of PFAS from the environment, underscoring the immense challenge ahead.

Belgium joins France, which faced a similar complaint in May 2026, as European countries increasingly face legal accountability for their handling of forever chemicals. The ECSR’s eventual decision could set a significant precedent for how European states address the growing PFAS crisis.
