PFAS in Water, Soil, and Sediment of the Fountain Creek Watershed, Colorado Springs, CO, USA

Ten perfluorinated alkyl substances (PFAS), including linear and branched isomers, were surveyed in samples collected from the Fountain Creek Watershed. Water, soil, and sediment samples were collected monthly from eight locations in the Fountain Creek Watershed for a full year (May 2018 through May 2019). Environmental samples were prepared via solid phase extraction (SPE) prior to high-performance liquid chromatography tandem mass spectrometry (LC/MS/MS) analysis on a Shimadzu LCMS-8030 system with coupled LC fitted with a Waters XBridge C18 column (50 mm x 4.6 mm x 3 micron particle). These data are useful for investigators interested in the long-term environmental presence and impact of PFAS released into the environment. We hypothesized that PFAS concentrations in water, soil, and sediment samples would be statistically significantly higher (P < 0.05) in environmental samples south of Peterson Air Force Base (PAFB). These data are of interest to investigators and entities seeking to understand the longer term impact of PFAS release into surface and groundwater resources.

本研究对芳泉溪流域（Fountain Creek Watershed）采集的样本中的十种全氟烷基物质（Perfluorinated Alkyl Substances, PFAS）开展检测分析，涵盖其直链与支链异构体。研究团队于2018年5月至2019年5月的完整一年周期内，每月从该流域的8个采样点位采集水体、土壤与沉积物样本。环境样本先通过固相萃取（Solid Phase Extraction, SPE）完成前处理，随后在搭载沃特世（Waters）XBridge C18色谱柱（50 mm × 4.6 mm × 3 μm粒径）的岛津LCMS-8030系统中，进行高效液相色谱-串联质谱（High-performance Liquid Chromatography Tandem Mass Spectrometry, LC/MS/MS）分析。本数据集可供关注环境中排放的PFAS长期存留状况与环境影响的科研人员参考使用。本研究提出假设：彼得森空军基地（Peterson Air Force Base, PAFB）以南区域的水体、土壤与沉积物样本中，PFAS浓度将呈现统计学意义上的显著升高（P < 0.05）。本数据集同样适用于旨在探究PFAS进入地表水与地下水资源后长期影响的科研人员及相关机构。
