饮用水中多氟烷基物质和全氟烷基物质(PFAS)的污染对消费者的发育、免疫、代谢和内分泌健康构成风险。我们根据美国环境保护局(US EPA)的第三项非管制污染物监测规则(UCMR3)计划，对2013-2015年的全国饮用水PFAS浓度进行了空间分析。生产或使用这些化合物的工业场所的数量、军事火力训练区的数量以及废水处理厂的数量都是公共供水中全氟辛烷磺酸检测频率和浓度的重要预测因素。在可检测到全氟辛烷磺酸水平的样本中，分水岭八位数水文单位内每增加一个军事站点，全氟辛烷磺酸增加20%，全氟辛烷磺酸和全氟辛烷磺酸均增加10%，全氟辛烷磺酸增加35%。有接受过使用含水成膜泡沫塑料培训的人员的民用机场的数量与超过最低报告水平的全氟辛烷磺酸的检测密切相关。我们发现，600万美国居民的饮用水供应量超过了美国环保局对全氟辛烷磺酸和全氟辛烷磺酸的终身健康建议(70毫微克/L)。较低的分析报告限制和对服务于10000人和私人水井的较小公用事业公司的额外采样将极大地有助于进一步查明全氟辛烷磺酸污染源。
Drinking water contamination with poly- and perfluoroalkyl substances (PFASs) poses risks to the developmental, immune, metabolic, and endocrine health of consumers. We present a spatial analysis of 2013–2015 national drinking water PFAS concentrations from the U.S. Environmental Protection Agency’s (US EPA) third Unregulated Contaminant Monitoring Rule (UCMR3) program. The number of industrial sites that manufacture or use these compounds, the number of military fire training areas, and the number of wastewater treatment plants are all significant predictors of PFAS detection frequencies and concentrations in public water supplies. Among samples with detectable PFAS levels, each additional military site within a watershed’s eight-digit hydrologic unit is associated with a 20% increase in PFHxS, a 10% increase in both PFHpA and PFOA, and a 35% increase in PFOS. The number of civilian airports with personnel trained in the use of aqueous film-forming foams is significantly associated with the detection of PFASs above the minimal reporting level. We find drinking water supplies for 6 million U.S. residents exceed US EPA’s lifetime health advisory (70 ng/L) for PFOS and PFOA. Lower analytical reporting limits and additional sampling of smaller utilities serving <10000 individuals and private wells would greatly assist in further identifying PFAS contamination sources.
