Remediation of PFAS contaminated soil using soil washing and immobilisation

该项目旨在评估土壤洗涤和固定作为具有成本效益的技术的适用性，用于修复受全氟烷基和多氟烷基物质（PFAS）污染的澳大利亚土壤。该项目预计将确定一系列全氟辛烷磺酸的补救效果，包括令人关切的全氟化学持久性遗留污染物的许多多氟前体。该项目将为理解与土壤清洗和固定技术相关的益处和局限性提供科学依据，并更全面地理解与残留在修复土壤中的前体形成全氟辛烷磺酸相关的未来责任。与利益相关者的合作将确保从商业和环境两方面获得利益，并消除对暴露于这些污染物的社区的潜在和持续的健康威胁。

This project aims to assess the applicability of soil washing and immobilisation as cost-effective techniques for the remediation of per- and poly-fluroalkyl substance (PFAS) contaminated Australian soils. The project expects to establish the efficacy of the remediation of a range of PFASs, including many polyfluorinated precursors of perfluorinated, chemically-persistent legacy pollutants which are of concern. The project will provide a scientific basis for understanding the benefits and limitations associated with soil washing and immobilisation techniques and a more comprehensive understanding of future liabilities associated with formation of PFASs from precursors remaining in remediated soils. Collaboration with stakeholders will ensure benefits are captured both commercially and environmentally, as well as removing a potential and on-going health threat to communities exposed to these contaminants.
