项目摘要
On February 3rd, 2023, a freight train derailment occurred in East Palestine in the State of Ohio. Following the train derailment, various hazardous chemicals, including volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) such as vinyl chloride (VC) and butyl acrylate (BA), and combustion by-products (e.g., polycyclic aromatic hydrocarbons) from a ‘controlled burn’ of the remaining VC and BA in the train cars, were released into nearby soils, sediments, groundwater aquifer, and waterways including the Ohio River which serves as a source of drinking water for more than 5 million people. Preliminary onsite chemical analyses by the investigators of this project (Purdue Team) showed that a variety of chemicals not tested for potential contamination by the responders were also found in heavily contaminated creeks, which are bordered by about 100 private drinking water wells located within a 2-mile radius of the East Palestine train derailment site. During their onsite inspection of selected East Palestine private wells and household drinking water systems, the Purdue Team also documented the use of well casings and building plumbing systems consisting of high-density polyethylene (HDPE) and crosslinked polyethylene (PEX), which are known to permeate and/or accumulate VOCs and/or SVOCs. This RAPID project will collect and analyze ephemeral water samples from surface water, groundwater, and household drinking water systems with the goal of characterizing and understanding the fate of the released VOCs/SVOCs within the plumbing systems and biofilms that form at the surfaces of HDPE/PEX pipes of household water systems in the East Palestine train derailment site and nearby communities. The successful completion of this project has the potential for transformative impact through the generation of new data and fundamental knowledge to guide and inform the design and implementation of effective remediation solutions for household water systems in the East Palestine train derailment site and nearby communities. Additional benefits to society will be achieved through student education and training including the mentoring of two graduate students at Purdue University. The formation and growth of biofilms on the surfaces of plastic plumbing materials have a major impact on water quality and safety in drinking water distribution systems. The release of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) during the East Palestine train derailment in Ohio provides a unique and time-sensitive opportunity to carry out fundamental investigations of the fate of these contaminants in plastic plumbing materials and the biofilms that form at their surfaces. This RAPID project will test the hypotheses that 1) that biofilms formed at the surfaces of polyethylene (PE) plumbing pipes in household water systems will sorb (accumulate) SVOCs in contaminated well water while the VOCs will permeate (diffuse) through the biofilms into the underlying PE polymer substrates, 2) contaminant desorption (release) from these biofilms will be slower than that from pristine PE surfaces, and 3) biofilm sloughing could cause acute incidences of high contaminant exposure. The specific objectives of the research are to 1) characterize heavily contaminated samples of creek water at the East Palestine chemical accident site using gas chromatography (GC)-mass spectrometry (MS) and proton transfer resonance (PTR)-time of flight (TOF)-MS to identify and select target VOCs/SVOCs for subsequent testing, 2) measure the diffusion (D) and solubility (K) coefficients of the selected VOCs/SVOCs in new/pristine high-density polyethylene (HDPE) resin pellets and pipes, and 3) measure the diffusion (D) and solubility (K) coefficients of the selected VOCs/SVOCs in biofilm-coated HDPE resin pellets and pipes using water from different impacted wells. The successful completion of this research has the potential for transformative impact through the generation of new data and fundamental knowledge on the fate of VOCs/SVOCs that accumulate in the HDPE plumbing systems and biofilms of household water systems that have been impacted by the East Palestine chemical spill accident. The new data and knowledge generated from this RAPID project could enable affected households to understand the extent of contamination of their water systems and design/implement effective remediation solutions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
2023年2月3日,俄亥俄州东巴勒斯坦发生货运列车脱轨事故。列车脱轨后,各种有害化学物质,包括挥发性有机化合物(VOCs)和半挥发性有机化合物(SVOCs),如氯乙烯(VC)和丙烯酸丁酯(BA),以及车厢内剩余VC和BA“受控燃烧”产生的燃烧副产物(如多环芳烃),被释放到附近的土壤、沉积物、地下水含水层、以及俄亥俄河等水道,这条河是500多万人的饮用水源。该项目的调查人员(普渡大学小组)进行的初步现场化学分析表明,在严重污染的小溪中也发现了各种化学物质,这些化学物质没有经过应急人员的潜在污染测试,这些小溪的边界是位于东巴勒斯坦火车脱轨地点2英里半径内的大约100个私人饮用水井。在对选定的东巴勒斯坦私人水井和家庭饮用水系统进行现场检查期间,Purdue团队还记录了由高密度聚乙烯(HDPE)和交联聚乙烯(PEX)组成的井套管和建筑管道系统的使用情况,这些材料会渗透和/或积累voc和/或SVOCs。该RAPID项目将收集和分析来自地表水、地下水和家庭饮用水系统的短暂水样,目的是表征和了解东巴勒斯坦火车脱轨现场和附近社区家庭供水系统HDPE/PEX管道表面形成的管道系统和生物膜中释放的挥发性有机化合物/ svoc的命运。该项目的成功完成有可能产生变革性影响,产生新的数据和基础知识,为设计和实施针对东巴勒斯坦火车脱轨现场和附近社区家庭供水系统的有效补救解决方案提供指导和信息。通过学生教育和培训,包括普渡大学两名研究生的指导,将为社会带来额外的好处。塑料管道材料表面生物膜的形成和生长对饮用水分配系统的水质和安全具有重要影响。俄亥俄州东巴勒斯坦火车脱轨期间挥发性有机化合物(VOCs)和半挥发性有机化合物(SVOCs)的释放提供了一个独特的和时间敏感的机会,可以对塑料管道材料中这些污染物的命运及其表面形成的生物膜进行基本调查。RAPID项目将测试以下假设:1)在家庭供水系统中聚乙烯(PE)管道表面形成的生物膜将吸收(积累)受污染井水中的SVOCs,同时voc将通过生物膜渗透(扩散)到下面的PE聚合物基质中;2)污染物从这些生物膜上的解吸(释放)将比从原始PE表面的解吸(释放)慢。3)生物膜脱落可引起急性高污染暴露。研究的具体目标是:1)利用气相色谱(GC)-质谱(MS)和质子转移共振(PTR)-飞行时间(TOF)-MS对东巴勒斯坦化学事故现场严重污染的水样进行表征,以识别和选择目标VOCs/SVOCs进行后续测试;2)测量所选VOCs/SVOCs在新型/原始高密度聚乙烯(HDPE)树脂颗粒和管道中的扩散(D)和溶解度(K)系数;3)采用不同受影响井的水,测量所选VOCs/SVOCs在生物膜包覆HDPE树脂颗粒和管道中的扩散(D)和溶解度(K)系数。这项研究的成功完成有可能产生变革性的影响,通过产生新的数据和关于VOCs/SVOCs命运的基本知识,这些VOCs/SVOCs积聚在受东巴勒斯坦化学泄漏事故影响的HDPE管道系统和家庭供水系统的生物膜中。该RAPID项目产生的新数据和知识可以使受影响的家庭了解其供水系统的污染程度,并设计/实施有效的补救方案。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
