Assessing the sustainability of treatment technologies for PFAS removal from water sources require a multifaceted approach. In this study, we reviewed existing literature to examine how treatment technologies for PFAS are evaluated in terms of sustainability. We focused on three key indicators commonly used in these studies: environmental sustainability, social impacts, and financial viability. The reviewed studies employed various methodologies, including LCA, LCCA, and TEA to quantify these indicators. Different impact assessment methods were integrated into these evaluations to provide a comprehensive analysis of the sustainability of PFAS treatment technologies. The assessment tools included TRACI, ReCipe, environmental footprint, Impact 2002+, social sustainability evaluation matrix, and net present value . These tools have been utilized to assess any treatment technologies environmental sustainability, social impacts, and financial viability values. The selection of impact assessment methodology varies depending on the type of infrastructure and the research objectives. This choice can significantly influence the results due to key differences in how the environmental relevance of indicators is considered. In sustainability studies, particularly in LCA, impact assessment methodologies are generally classified into two main types: midpoint models and endpoint models. These models are used to evaluate the environmental impacts of a system, product, or process at different stages and levels of detail.
