Global persistent chemical contamination and water security risks

Global ecosystems face ongoing contamination from persistent chemical pollutants, including per- and polyfluoroalkyl substances (PFAS) and banned flame-retardant compounds like polybrominated diphenyl ethers (PBDEs). PFAS, frequently referred to as ‘forever chemicals’, are increasingly detected in soil, groundwater, and drinking water, leading to new enforceable drinking water limits by the EPA. In Europe, legacy pollutants such as PBDEs continue to circulate through recycling streams and contaminate environments ranging from Spanish offices to alpine snow in Slovakia. In Italy, the organization Legambiente has highlighted the presence of emerging contaminants—including microplastics, pesticides, and pharmaceutical residues—in rivers, lakes, and aquifers. Research indicates that conventional purification systems often fail to remove these substances. Data shows that between 2007 and 2023, reporting facilities released over 7,500 tons of substances, such as metals and chlorinated solvents, into Italian waters. Legambiente has proposed a ‘One Health’ approach to the Italian government to mitigate the significant economic risks associated with water treatment and contamination costs. Recent developments in Italy include legal proceedings against two former directors of a Syensqo chemical plant in the Piedmont region. They face trial region for an involuntary environmental disaster following PFAS contamination contamination. By the summer of 2026, Europe faced compounding water management challenges driven by extreme weather and chemical risks. Copernicus reported that 52 percent of Europe experienced intense heat stress, with major rivers reaching their lowest summer discharge levels since 1992. While parts of Northwest Europe remained moist, France, Spain, Italy, and Germany suffered severe shortages. In Germany’s Rheinland-Pfalz region, extreme drought has potentially affected 90,000 people and is linked 70 percent of the area, threatening groundwater regeneration. In Italy, while Puglia’s Capitanata reservoirs show higher availability than in 2025, levels remain insufficient to elevated cancer rates. Legambiente has warned meet demand. Experts continue to warn that addressing PFAS pollution alone could prevent costs of up emerging pollutants like PFAS, microplastics, and pharmaceuticals pose long-term risks to 440 billion euros in Europe by 2050. human health and ecosystems.
