This project aims to develop two methods for the in situ remediation of per- and poly-fluroalkyl substances (PFAS) contamination, downhole foam fractionation for in situ groundwater treatment, and in situ fluidisation for soil treatment, both separately and in combination. Using these methods, PFASs will be removed in the form of a foam, which will be extracted as a liquid concentrate. These techniques could enable PFAS removal efficiencies of greater than 90%, providing entirely new methods for the aggressive removal of PFAS from contaminated source zones. This project will enable the rapid removal of the bulk of the PFAS present in soils and groundwater and reduce the potential for further spreading.

该项目旨在开发两种原位修复全氟烷基物质和多氟烷基物质（PFAS）污染的方法，即用于原位地下水处理的井下泡沫分馏，以及用于土壤处理的原位流化，可单独使用或组合使用。使用这些方法，PFAS 将以泡沫的形式被去除，然后以液体浓缩物的形式被提取。这些技术可以使 PFAS 去除效率超过 90%，为从污染源区域积极去除 PFAS 提供全新的方法。该项目将能够快速去除土壤和地下水中存在的大部分 PFAS，并减少进一步扩散的可能性。
