This paper is focused on the development and field deployment of a multi-parameter and distributed fiber optic sensor 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 is leveraged through the development of transducers for distributed sensing of temperature and pressure which are critical performance parameters for assessing the efficiency of any ISTR process.
