项目摘要
The acquisition of a Geoprobe 7822DT system with direct-push (DP) soil, sediment, and groundwater sampling tools and logging and imaging capabilities will serve the research and educational needs of TAMU-CC and South Texas. The tightly coupled local and regional economic interplay of the Gulf Coast's natural resources (i.e., regional oil/gas and commercial and recreational fishing industries) has increased prosperity and resulted in industry and population growth in South Texas. This comes with concerns over contamination of the already limited groundwater resources and questions about ecosystem and environmental health. The geoprobe is the industry benchmark equipment that improves the investigator's capacity to adapt to changing research problems, whether they are focused on environmental, geotechnical, or exploration work. The new mobile, small footprint geoprobe systems, accommodating a variety of tooling and imaging capabilities, offer capabilities for obtaining high-resolution geologic, hydrogeologic and geochemical information of the shallow subsurface soils and rocks. An understanding of vertical changes in sediment types, water content, and conductivity, and the high-resolution chemical makeup of water stored in the ground, helps determine prominent water and pollutant migration pathways and locate areas that need attention for remediation purposes, for instance. The geoprobe system will provide students in the region, with a large majority from underrepresented minority groups in STEM fields, with hands-on experience and practical training necessary to make them competitive in the job market. This leading-edge geoprobe system includes DP drilling capabilities for well/piezometer installation and coring, discrete aseptic water and sediment sampling, and DP mapping instrumentation for formation permeability, lithology, and water content. This geoprobe system will complement the efforts by researchers (faculty and students) at TAMUCC, and other South Texas academic institutions, using ultrahigh performance chemical and biological analytical instrumentation, by increasing their capability to obtain discrete and aseptic samples in a variety of environments. There are many benefits to obtaining high-quality and high-resolution field data using the Geoprobe 7822DT with auxiliary coring, aseptic sampling, probing and logging tools, including among others: an understanding of the detailed microstratigraphy that controls flow and solute migration; the provision of samples from which accurate physical, microbial and chemical properties can be determined; an in situ determination of contaminant mass distributions and partitioning, particularly within highly heterogeneous substrates and enabling unambiguous and precise characterization of the water storage and pore structure characteristics of any earth formations. These high-resolution depth profile physical characterizations will lead to advances in the scientific understanding of mobilization and transport of contaminants from soils to groundwater to surface water and the long-term chemical cycling within the groundwater-surface water/seawater transition zone. In TAMUCC's region, there has been sparse research on the presence, fate and impacts of anthropogenic chemicals in the soil and groundwater from domestic, agricultural, and industrial uses. An in-house Geoprobe will drastically enhance the capabilities of both researchers at TAMU-CC and those within the region leading to integrated holistic approaches to environmental research. Data obtained from these capabilities is foundational for scientific research in different STEM fields such as geology, biogeochemistry, and engineering. By supplementing the existing chemical characterization capabilities with the proposed Geoprobe System, the scope of research that can be conducted at this Hispanic Serving Institution (HSI) will be expanded.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.
Geoprobe 7822 DT系统具有直接推动(DP)土壤,沉积物和地下水采样工具以及测井和成像功能,将满足TAMU-CC和南德克萨斯州的研究和教育需求。墨西哥湾沿岸自然资源的紧密耦合的地方和区域经济相互作用(即,区域石油/天然气以及商业和休闲渔业)增加了繁荣,并导致南德克萨斯州的工业和人口增长。随之而来的是对已经有限的地下水资源的污染以及生态系统和环境健康问题的担忧。geoprobe是行业的基准设备,提高了调查人员的能力,以适应不断变化的研究问题,无论他们是专注于环境,岩土工程,或勘探工作。新的移动的、占地面积小的地质探测器系统具有各种工具和成像能力,能够获得浅层地下土壤和岩石的高分辨率地质、水文地质和地球化学信息。例如,了解沉积物类型、含水量和电导率的垂直变化,以及地下储存水的高分辨率化学组成,有助于确定水和污染物的主要迁移途径,并确定需要注意的补救区域。geoprobe系统将为该地区的学生提供实践经验和必要的实践培训,使他们在就业市场上具有竞争力。这种先进的地质探测器系统包括用于井/压力计安装和取芯的DP钻井能力、离散无菌水和沉积物取样以及用于地层渗透率、岩性和含水量的DP绘图仪器。该geoprobe系统将补充TAMUCC和其他南德克萨斯学术机构的研究人员(教师和学生)的努力,使用高性能化学和生物分析仪器,提高他们在各种环境中获得离散和无菌样品的能力。使用Geoprobe 7822 DT和辅助取芯、无菌取样、探测和测井工具获得高质量和高分辨率的野外数据有许多好处,其中包括:了解控制流动和溶质迁移的详细微观地层;提供样品,从中可以确定准确的物理、微生物和化学特性;污染物质量分布和分配的现场测定,特别是在高度不均匀的基质中,并能够明确和精确地表征任何地层的水储存和孔隙结构特征。这些高分辨率的深度剖面物理特征将有助于提高对污染物从土壤到地下水再到地表水的移动和迁移以及地下水-地表水/海水过渡区内的长期化学循环的科学认识。在TAMUCC地区,对家庭、农业和工业使用的土壤和地下水中人为化学品的存在、归宿和影响的研究很少。一个内部的地球探测器将大大提高TAMU-CC的研究人员和该区域内的研究人员的能力,从而对环境研究采取综合全面的方法。从这些能力中获得的数据是地质学、地球化学和工程等不同STEM领域科学研究的基础。通过补充现有的化学表征能力与拟议的地球探测系统,可以在这个西班牙裔服务机构(HSI)进行的研究范围将扩大。这个奖项反映了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。
