APPLICATION OF SPECTRAL INDUCED POLARIZATION FOR CHARACTERIZING SURFACTANT-ENHANCED DNAPL REMEDIATION IN LABORATORY COLUMN EXPERIMENTS
Deng, Y., X. Shi, Z. Zhang, Y. Sun, J. Wu, and J. Qian.
Journal of Contaminant Hydrology 230:103603(2020)
Spectral induced polarization (SIP) measurements were conducted on DNAPL contaminated soil in columns to quantitatively assess the ability of SIP to monitor surfactant-enhanced DNAPL remediation process. Chemical data was simultaneously collected during the remediation process to verify the results obtained by SIP. A series of column flushing experiments were conducted under different flow rates, surfactant concentrations, and fluid salinities to measure variations of the subsurface environment.
