Fiber Optic Sensors for Distributed Monitoring of Soil and Groundwater during In-Situ Thermal Remediation

摘要

This paper is focused on the development and field deployment of multi-parameter and distributed fiber optic sensors for monitoring of soil and groundwater during in-situ thermal remediation of contaminated brownfields. In-Situ Thermal Remediation (ISTR) is a process in which the soil and groundwater are heated using localized heat sources to evaporate and extract hazardous substances and pollutants from brownfields. In this research, the unique advantages of fiber optic sensors are leveraged through the development of transducers for distributed sensing of soil temperature and level of groundwater which are critical performance parameters for assessing the efficiency of any ISTR process.
