This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This award will fund the acquisition of an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) in the HDR Environmental Engineering Laboratory located at South Dakota State University (SDSU), which will be used to support research, teaching and outreach activities within the Water and Environmental Engineering Research Center (WEERC). Analysts have been using radially viewed ICP-OES and atomic absorption instruments for over 20 years. The improvement in sensitivity with an axially viewed plasma typically yields a 5- to 10-fold improvement in detection limits while providing near simultaneous identification of multiple ions at ug/L concentrations. A host of emerging issues are planned to be researched using the ICP-OES including the following studies: impact of corrosion on existing and new water storage and delivery systems; identifying low levels of lead and copper in drinking water due to changes in disinfection chemicals; quantification of the low level concentrations anticipated for various metal contaminants which occur naturally as well as anthropogenically from industrial and mining operations; expansion of research in the characterization of the airborne deposition of heavy metals, surface water transport of heavy metals, and analysis of bio-indicators of heavy metal contamination. This research support will enable South Dakota to attract and support qualified graduate students and to provide training and research experience to undergraduate students as well as increased outreach to rural water systems and to the environmental science program at Oglala Lakota College (OLC). The mission of the WEERC is to enhance the habitability and economic development of the Northern Great Plains through multidisciplinary research of the region's water and related land resources. The center supports this mission through the conduct of engineering and related research on significant issues affecting water resources by working to foster interdisciplinary work on the conservation, development, management and use of water and related land resources. Finally, the equipment will be used in direct collaborative research activities between SDSU and OLC researchers involving project-based service learning in support of land grant missions of both institutions serving under-represented students in the sciences and engineering.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该奖项将资助位于南达科他州州立大学（SDSU）的HDR环境工程实验室购买电感耦合等离子体光发射光谱仪（ICP-OES），该仪器将用于支持水与环境工程研究中心（WEERC）的研究、教学和推广活动。 分析师使用放射状观察的ICP-OES和原子吸收仪器已有20多年。 轴向观察等离子体的灵敏度的提高通常会使检测限提高5至10倍，同时几乎同时识别微克/升浓度的多种离子。 计划使用ICP-OES研究一系列新出现的问题，包括以下研究：腐蚀对现有和新的水储存和输送系统的影响;确定由于消毒化学品的变化而导致的饮用水中铅和铜的低水平;量化自然产生的各种金属污染物以及工业和采矿作业的有害物质的预期低水平浓度;扩大对空气中重金属沉积特性、重金属的地表水迁移以及重金属污染生物指标分析的研究。 这项研究支持将使南达科他州吸引和支持合格的研究生，并提供培训和研究经验，本科生以及增加推广到农村供水系统和环境科学计划在奥格拉拉拉科塔学院（OLC）。 WEERC的使命是通过对该地区水资源和相关土地资源的多学科研究，提高北方大平原的宜居性和经济发展。该中心支持这一使命，通过对影响水资源的重大问题进行工程和相关研究，努力促进水资源和相关土地资源的保护，开发，管理和使用的跨学科工作。 最后，这些设备将用于SDSU和OLC研究人员之间的直接合作研究活动，涉及基于项目的服务学习，以支持这两个机构为科学和工程领域代表性不足的学生提供土地赠款任务。
