摘要

针对地下水、地表水和其他环境介质中存在的各种全氟和多氟烷基物质 (PFAS),已经投入了大量资金来开发处理技术,特别是破坏性方法。为了帮助监管机构、资助机构和从业人员评估 PFAS 处理技术的性能,我们开发了一种多证据方法。本文介绍了证明某项技术有效的三个证据:(1)观察到目标 PFAS 浓度下降;(2)确定并量化了 PFAS 处理转化产物;以及(3)提出了与先前研究一致并有数据支持的处理机制。此外,还介绍了其他考虑因素,以便就知识差距和未来测试的优先事项得出结论。总之,这些证据和其他考虑因素有助于说明全氟辛烷磺酸处理的复杂性,加强研究计划,规范技术评估人员的审查,并告知人们对全氟辛烷磺酸处理技术的现实期望。

A Multiple Lines of Evidence Approach to Demonstrate Effectiveness of PFAS Remediation Technologies

A Multiple Lines of Evidence Approach to Demonstrate Effectiveness of PFAS Remediation Technologies

Significant investments have been made to develop treatment technologies, particularly destructive approaches, for a variety of per- and polyfluoroalkyl substances (PFAS) that are present in groundwater, surface water, and other environmental media. A multiple lines of evidence approach were developed to assist regulators, funding agencies, and practitioners in evaluating PFAS treatment technology performance. This article describes each of three lines of evidence that a technology is effective: (1) decrease in target PFAS concentrations is observed; (2) PFAS treatment transformation products are identified and quantified; and (3) a treatment mechanism is proposed that is consistent with previous studies and supported by data. Other considerations are also described to inform conclusions about knowledge gaps and priorities for future testing. Collectively, these lines of evidence and other considerations help communicate the complexities of PFAS treatment, strengthen research plans, standardize technology evaluator reviews, and inform realistic expectations of PFAS treatment technologies.
