项目摘要
Stormwater runoff is a national challenge that increases in scope as population and urbanization increases. When rain falls on streets, rooftops, and other hard surfaces, contaminants can be washed into rivers and lakes, impacting aquatic life and drinking water sources. Green stormwater treatment was developed to remove stormwater contaminants as a solution to this problem. Although this technology has potential to transform stormwater from a waste to a valuable resource, the treatment mechanisms in most systems is poorly understood. This knowledge gap prevents the wider adoption of this technology. To address this gap, the research team will use cutting-edge chemical and biological analytical tools to understand how bacteria, fungi, and plants combine with engineered stormwater filter media for enhanced treatment efficiency. The broader impacts to society include wider adoption of inexpensive, low-maintenance stormwater treatment systems to improve water quality and protect the Nation's drinking water sources. The investigator will engage college and middle school students in the teaching-learning continuum to increase scientific literacy. An added benefit is the enhancement of the 'pipeline' of students from diverse backgrounds into the field of water supply science and engineering.The research goal of this CAREER project is to provide fundamental insights into the coupled biological and abiotic processes in stormwater green infrastructure systems to sustain contaminant removal. Specific objectives of the research plan are to: 1) discover novel approaches to bioaugment stormwater infiltration media; 2) determine uptake and transformation of stormwater contaminants in plants; and 3) characterize coupled biological-abiotic redox transformations. Advanced high-resolution mass spectrometry coupled with semi-targeted metabolomics will be used to elucidate novel contaminant transformation products and pathways. New biological enrichment approaches will be applied to create stormwater filtration media with redox-active sorptive surfaces. Electron shuttling for stormwater contaminant transformation will be characterized using x-ray photoelectron spectroscopy and electrochemistry. The research plan will be fully integrated into a formally-assessed education plan to engage the public on water quality and inspire and train the next generation of scientists and engineers. Educational objectives will: 1) create 8th grade water science and engineering content modules to meet teacher needs for next generation science standards by engaging university students; 2) host STEM education teachers for hands-on research experiences; 3) engage members of the public on stormwater quality topics at STEM festivals; and 4) disseminate research to current practitioners and decision makers. The integrated research and education plan will help move society toward low-energy water quality solutions in the face of increasing impacts from non-point pollutants and shift stormwater from a waste to a resource.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.
雨水径流是一个全国性的挑战,随着人口和城市化的增加,范围也在扩大。当雨水福尔斯落在街道、屋顶和其他坚硬的表面时,污染物会被冲入河流和湖泊,影响水生生物和饮用水源。绿色雨水处理是为了解决这一问题而开发的。虽然这项技术有可能将雨水从废物转化为宝贵的资源,但大多数系统的处理机制仍知之甚少。这种知识差距阻碍了这项技术的广泛采用。为了解决这一差距,研究团队将使用先进的化学和生物分析工具来了解细菌,真菌和植物如何与工程雨水过滤介质结合联合收割机,以提高处理效率。对社会的更广泛影响包括更广泛地采用廉价、低维护的雨水处理系统,以改善水质并保护国家的饮用水源。调查员将使大学和中学生参与教学,以提高科学素养。一个额外的好处是“管道”的学生从不同的背景到供水科学和工程领域的增强。这个CAREER项目的研究目标是提供基本的见解,在雨水绿色基础设施系统的耦合生物和非生物过程,以维持污染物的去除。研究计划的具体目标是:1)发现生物增强雨水渗透介质的新方法; 2)确定植物对雨水污染物的吸收和转化; 3)表征耦合的生物-非生物氧化还原转化。先进的高分辨率质谱加上半靶向代谢组学将用于阐明新的污染物转化产物和途径。新的生物富集方法将被应用于创造具有氧化还原活性吸附表面的雨水过滤介质。电子穿梭雨水污染物转化的特点是使用x射线光电子能谱和电化学。该研究计划将完全纳入正式评估的教育计划,以吸引公众关注水质,并激励和培训下一代科学家和工程师。教育目标将:1)创建八年级水科学和工程内容模块,通过吸引大学生来满足教师对下一代科学标准的需求; 2)主持STEM教育教师进行实践研究经验; 3)在STEM节日上让公众参与雨水质量主题;以及4)向当前的从业者和决策者传播研究。综合研究和教育计划将有助于推动社会向低能耗的水质解决方案,面对日益增加的非点源污染物的影响,并将雨水从废物转变为资源。该奖项反映了NSF的法定使命,并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
