High quality geochemical analyses of waters, minerals, and rocks using state-of-the-art analytical equipment are important to advance our knowledge of important societally relevant environmental questions and to train the next-generation workforce of geochemists and analytical chemists. This award will purchase a plasma-source, triple, quadrupole mass spectrometer for a four-year college that has a outstanding reputation for graduating undergraduates who are able to transition directly into high profile graduate schools and technical jobs that require experience in using state-of-the-art analytical instrumentation. The instrument supports research, much of it societally relevant, and trains undergraduate students in the use of state-pf-the-art geochemical techniques. The instrument is the primary driver of a new institutional initiative to address water quality and contamination: The Union College Water Initiative. Its goals include examining drinking water contamination across the region, assessing potentially polluted areas (including fracking fluids and heavy metal contamination in lakes and radionuclides in shale- and granite- hosted groundwaters), and monitoring water chemistry in active volcanic regions in the Caribbean. In addition to this societal impact, the new institute will give Union College greater exposure to the community as a resource. The drinking water project will educate student participants about the potential sources of heavy metals in drinking water, providing them with the opportunity to create a public brochure and website explaining the sources of the metals and contaminants, EPA limits, and strategies for dealing with contaminated water. Within the community, students will act as liaisons and ambassadors, collecting the water samples or instructing others in collection methods, and then explaining results. Other water projects will target specific locations and sources of pollutants and provide critical information for communities that have suffered adverse environmental impacts. Union College has partnered with the University of West Indies to analyze water samples near volcanoes to establish a chemical baseline for use in future volcano monitoring efforts. It has also initiated outreach efforts to inform the public about potential hazards. All of the projects involve undergraduate students, providing important analytical training and research skills, which are critical in preparing the science and engineering workforce. The mass spectrometer will also be used in class projects and in course exercises, exposing more students to state-of-the-art analytical instrumentation. Societally relevant environmental and pollution-related water quality studies will be carried out with the new Union College inductively coupled plasma mass spectrometer. The new instrument has higher detection limits than Union College's present aging instrument that is near the end of its useful lifetime. In addition the new instrument has increased analytical speed and dynamic mass range. This allows for greatly enhanced interference rejection enabled by the new mass filter configuration, which will enable the development of a new analytical repertoire of geochemical species of interest to the research specialties of faculty and students at Union College. Projects include: (1) the study of volatile concentrations in magmatic apatite to better understand the state of volatile saturation prior to eruptions and to correlate widely dispersed volcanic deposits; (2) advance studies of trace element zoning in speleothems, which may be useful in both paleoclimate reconstruction and to track modern and archeological pollution events; (3) U-Pb dating of zircons with a quadrupole ICP-MS; (4) measuring biogenic silica in terrestrial lake core samples with increased throughput and decreased amount of sample destroyed; and (5) measuring element diffusion profiles in experimental iron-nickel alloys and sulfides to constrain the formation of planetary cores. All of these projects, and more, will benefit from the instrument's high sensitivity, rapid sample throughput, and ability to resolve interferences. The resulting data will establish important datasets that will improve our scientific understanding of various hydrologic systems that impact our present society.

使用最先进的分析设备对沃茨、矿物和岩石进行高质量的地球化学分析，对于提高我们对重要的社会相关环境问题的认识，以及培养下一代地球化学家和分析化学家队伍都很重要。该奖项将为一所四年制大学购买一台等离子源、三重、四极质谱仪，该大学在毕业本科生中享有盛誉，他们能够直接过渡到高知名度的研究生院和需要使用最先进的分析仪器的经验的技术工作。该仪器支持研究，其中大部分与社会相关，并培训本科生使用最先进的地球化学技术。该文书是一个新的机构倡议，以解决水质和污染的主要驱动力：联合大学水倡议。其目标包括检查整个地区的饮用水污染情况，评估潜在污染地区（包括湖泊中的水力压裂液和重金属污染以及页岩和花岗岩地下水中的放射性核素），并监测加勒比地区活火山地区的水化学。 除了这种社会影响外，新学院还将使联合学院更多地接触社区作为资源。饮用水项目将教育学生参与者关于饮用水中重金属的潜在来源，为他们提供机会创建一个公共小册子和网站，解释金属和污染物的来源，EPA限制和处理污染水的策略。在社区内，学生将担任联络员和大使，收集水样或指导他人收集方法，然后解释结果。其他水项目将针对具体地点和污染物来源，并为遭受不利环境影响的社区提供重要信息。联合学院与西印度群岛大学合作，分析火山附近的水样，以建立一个化学基线，用于未来的火山监测工作。它还开展了外联工作，向公众宣传潜在的危害。所有项目都涉及本科生，提供重要的分析培训和研究技能，这对培养科学和工程人才至关重要。质谱仪还将用于课堂项目和课程练习，使更多的学生接触到最先进的分析仪器。将使用联合学院新的电感耦合等离子体质谱仪进行与社会有关的环境和污染相关的水质研究。新仪器的检测限比联合学院目前的老化仪器更高，老化仪器的使用寿命即将结束。此外，新仪器提高了分析速度和动态质量范围。这使得大大增强了干扰抑制启用新的质量过滤器配置，这将使感兴趣的地球化学物种的研究专业的教师和学生在联合学院的一个新的分析剧目的发展。项目包括：（1）研究岩浆磷灰石中的挥发分浓度，以更好地了解火山爆发前的挥发分饱和状态，并与广泛分布的火山沉积物相关联：（2）进一步研究洞穴沉积物中的微量元素分带，这可能有助于古气候重建和现代及考古学污染事件的追踪：（3）用四极ICP-MS进行锆石U-Pb定年;（4）测量陆地湖泊岩心样品中的生物硅，增加处理量，减少样品破坏量;（5）测量实验性铁镍合金和硫化物中的元素扩散分布，以限制行星核心的形成。所有这些项目以及更多项目都将受益于该仪器的高灵敏度、快速样品通量和解决干扰的能力。由此产生的数据将建立重要的数据集，这将提高我们对影响我们当今社会的各种水文系统的科学理解。
