Implanted Membranes for Characterization and Monitoring

描述(申请人提供)：美国许多地方依靠地下水作为饮用水的来源。在我们的工业化社会中，污染威胁着地下水的供应，因此对人们的健康构成了重大威胁。这项第一阶段SBIR研究建议为解决目前地下水监测方面的不足提供了一种创新的解决方案。有了拟议的取样膜，就有可能在修复开始之前，通过提供更具成本效益和更及时的数据，更好地描述受污染场地的特征。修复开始后，可以使用相同的工具来主动监控修复的状态，并允许站点管理员就修复策略做出更好的决策。此外，这两种选择的使用成本都比目前的技术低得多。建议的采样器是无源设备，可以使用最先进的直接推进技术或传统钻探轻松地部署在地下。此外，采样器还可以改装到现有的监测井中，从而可以将过时的井转换为最先进的技术。

DESCRIPTION (provided by applicant): Many localities across the Unites States rely upon groundwater as the source of drinking water. In our industrialized society, pollution threatens the groundwater supply and, therefore, poses a significant health risk to the population. This Phase I SBIR research proposal offers an innovative solution to current inadequacies in groundwater monitoring. With the proposed sampling membranes, it will be possible to better characterize a contaminated site before remediation begins by providing more cost-effective and timely data. Once remediation begins, the same tools can be used to actively monitor the status of the remediation and allow site managers to make better decisions about remediation strategies. In addition, both of these options can be employed at a significantly lower cost than current technologies. The proposed samplers are passive devices that can be easily deployed in the subsurface using either state-of-the-art direct push technology or conventional drilling. Also, the samplers can be retrofit into existing monitoring wells, making it possible to convert antiquated wells to state-of-the-art technology.
