特朗普政府搁置全国污水中PFAS调查

特朗普政府已将美国环保署（EPA）的一项全国污水PFAS（永久性化学物质）调查搁置近两年，该调查原定于2024年10月提交白宫管理与预算办公室审批1。根据典型的审批周期约60天计算，这份报告应已完成审批程序，但目前仍未推进1。

这项调查旨在识别工业污染源，为制定限制PFAS排放的国家性法规提供科学依据1。EPA工程与分析部主任罗伯特·伍德（已于2024年退休）曾表示，确定排放PFAS的主要产业"将使我们能够进行详细研究并开发全国限制措施"1。然而，这一搁置举措引发环保界质疑。EPA前水质办公室负责人贝琪·瑟瑟兰德指出，"这让人怀疑他们是否真的想阻止PFAS，或者对化工行业来说，发现谁在排放PFAS造成了太大的干扰"1。非营利组织环保工作组的首席科学官戴维·安德鲁斯补充说，缺乏这项全国性调查使得生物固体风险评估遭受批评1。

The Trump administration has halted a comprehensive Environmental Protection Agency survey examining PFAS contamination in wastewater, according to former EPA officials.1 The survey was originally scheduled to be submitted to the White House Office of Management and Budget in October 2024 for approval, but has remained stalled for nearly two years despite a typical review period of approximately 60 days.1 The investigation was designed to identify industrial sources of per- and polyfluoroalkyl substances emissions, information that would form the basis for developing national regulations to restrict PFAS discharge.1

The delay has drawn criticism from environmental advocates and public health experts who argue the government is obstructing crucial efforts to understand pollution sources. Robert Wood, former director of the EPA's Engineering and Analysis Division who retired in 2024, stated that "if we could identify the first, second or third industries emitting PFAS, then we start doing detailed studies and developing national limits."1 Betsy Southerland, former head of the EPA's water quality office, expressed skepticism about the administration's intentions, suggesting "this raises the question of whether they really want to stop PFAS, or whether finding out who is emitting PFAS is too much of a disruption to the chemical industry."1 David Andrews, chief scientist at the nonprofit Environmental Working Group, noted that biosolids risk assessments have faced criticism due to the absence of a nationwide survey, which "has been stalled at OMB for nearly two years."1
