An NSF EAR Postdoctoral fellowship was awarded to Dr. Ranalda Tsosie to carry out a research, teaching and professional development experience at Montana State University under the mentorship of Dr. Ellen Lauchnor and Dr. Mari Eggers. The PI will engage with three communities to address arsenic contamination issues. Two of these communities are located on Indigenous lands, the Navajo and Crow reservations, and the third community is in a rural community in the state of Montana. The proposed research will focus on the ongoing private well arsenic contamination issues in households in Montana and the contamination issues of unregulated water sources located on the Navajo reservation. Specifically, the proposed use-inspired research will determine the species of arsenic and test cost effective and commercially available arsenic removal filters. A second objective is to optimize the design of a current prototype of silica polyamine composite based point of use filter (SPC-POU) developed by Dr. Tsosie during her dissertation research at the University of Montana. This research will advance the knowledge of arsenic remediation and develop an innovative method of addressing arsenic contamination. Arsenic has been studied extensively and much effort has gone into developing more cost-effective methods of remediation. Despite all these efforts, many households throughout the U.S. continue to face issues with arsenic exceedance in their drinking water. This research aims to tackle these issues by working with these households in Montana that do not have access to a publicly monitored water supply. In addition, on the Navajo reservation there are some households that do not have running water in their homes and must rely on unregulated water sources for their household water needs. It is communities/households like these, that this research will be the most impactful.This project is jointly funded by the Division of Earth Sciences and the Established Program to Stimulate Competitive Research (EPSCoR).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.

在埃伦·劳克诺（Ellen Lauchnor）博士和玛丽·艾格斯（Mari Eggers）博士的指导下，授予了Ranalda Tsosie博士的NSF耳朵博士后奖学金，在蒙大拿州立大学（Montana State University）进行研究，教学和专业发展经验。 PI将与三个社区互动以解决砷污染问题。其中两个社区位于土著土地，纳瓦霍和乌鸦保留地，第三个社区位于蒙大拿州的一个农村社区。拟议的研究将重点介绍蒙大拿州家庭正在进行的私人井砷污染问题以及纳瓦霍保留地上不受管制的水源的污染问题。具体而言，拟议的使用启发的研究将确定砷和测试成本效益和市售的砷清除过滤器的物种。第二个目标是优化由Tsosie博士在蒙大拿大学的论文研究期间开发的基于二氧化硅复合点的使用点（SPC-POU）的当前原型。这项研究将促进有关砷修复的知识，并开发一种解决砷污染的创新方法。已经对砷进行了广泛的研究，并为开发更具成本效益的补救方法而努力。尽管做了所有这些努力，但美国各地的许多家庭仍在饮用水中面临超出砷的问题。这项研究旨在通过与蒙大拿州的这些家庭合作解决这些问题，而这些家庭无法获得公开监控的供水。此外，在纳瓦霍预订上，有些家庭在家中没有自来水，必须依靠不受管制的水源来满足其家庭用水需求。这项研究将是最具影响力的社区/家庭。该项目由地球科学部共同资助和刺激竞争性研究的既定计划（EPSCOR）。该奖项反映了NSF的法定任务，并被认为是通过该基金会的知识分子功能和广泛的影响来评估CRITERIA CRITERIA的评估。
