In-Situ Quantification of Chlorinated Hydrocarbon Mass Flux and Intrinsic Remediation Using Fiber Optic Biosensors

0119972Jawitz该探索性项目将研究光纤传感器的发展，以测量地下水污染物质量通量和累积污染物特定的微生物活性原位和真实的时间。 一种新的，综合的质量流量为基础的评估方法，提出了优先于传统的浓度为基础的方法。 质量通量量化是必要的，以评估补救的有效性，通过内在的（即，自然衰减）或有源（例如，泵和原位冲洗处理）装置。 所关注的污染物是氯化碳氢化合物，特别是三氯乙烯和四氯乙烯及其降解产物。 对污染物质量通量进行量化将特别有助于确定地下水污染对人类和环境的风险。

0119972JawitzThis exploratory project will investigate the development of fiber optic sensors to measure groundwater contaminant mass fluxes and cumulative contaminant-specific microbial activity in-situ and real time. A novel, integrative mass-flux based assessment approach is proposed in preference to traditional concentration-based approaches. Mass flux quantification is necessary to evaluate the effectiveness of remediation, through either intrinsic (i.e., natural attenuation) or active (e.g., pump and treat of in situ flushing) means. The contaminants of interest are chlorinated hydrocarbons, specifically TCE and PCE and their degradation products. Quantification of contaminant mass flux will be especially useful in characterizing risks to humans and the environment from groundwater contamination.
