PFAS – die “ewigen Chemikalien“

Per- and polyfluorinated alkyl substances, PFAS for short, are not naturally occurring substances and are known as "eternal chemicals".

They are found in products such as Teflon pans, shampoos, pizza boxes, carpets and clothing. A very large source of PFAS is firefighting foam, which is often used at sites with fire incidents, on firefighting grounds, military properties and airports.

They have therefore become a major environmental concern since the 1960s. PFAS are toxic to humans and animals and are suspected of being carcinogenic, affecting hormone balance, increasing the risk of heart attacks or the likelihood of developing neuronal diseases such as Alzheimer's disease.

Due to their extreme longevity, PFASs accumulate in high concentrations, especially near factories, landfills and military installations. PFASs spread further in nature via the water cycle and transport of substances and eventually enter the food chain via water and soil.

There is currently growing concern in Europe about the impact of PFAS on the environment and human health. In recent years, more and more cases of PFAS contamination have been reported in Europe.

Despite the complex structures of these toxic chemicals, safe and inexpensive remediation of PFAS is possible.

Authorities often demand remediation targets that are in the order of detection limits. However, these can hardly be achieved by proportionate means in remediation. A more sensible approach is to consider each PFAS contaminated site individually and focus on hazard preventation by concentrating on hazard assessment and the derivation of site-specific action values.
However, there are opportunities to reduce costs through targeted quantification of toxicological exposure risk and to formulate pragmatic site-specific remediation targets.

Durch die Einbindung der Unternehmen HPC international SAS und Sensatec GmbH in ihre “Initiative Brownfield Solutions” kann die Geobality Europe nun eine kostengünstige Sanierung von PFAS anbieten. Unternehmen und Kommunen erhalten Unterstützung bei der Erarbeitung von Lösungen für dieses Problem, was dazu beitragen kann, die Belastung von Böden und Grundwässern mit PFAS zu reduzieren und somit die Umwelt zu schützen.
