[AGE04-P11] A Case Study of Combining Geophysical Prospecting Techniques at a DNAPLs Contaminated Site
Keywords:Dnapls, electrical resistivity tomography (ERT), ground-penetrating radar (GPR)
In this study, we presented the investigation outcomes of electrical resistivity tomography (ERT) and ground-penetrating radar (GPR) at the DNAPLs-impacted site. Evaluation of RIP technique deployment in detecting buried DNAPLs and assessment of remediation efforts are also discussed. Results indicated zones with anomalously high resistivity to be associated with contaminated DNAPLs presence. Resistivity maps clearly outlined the subsurface distribution and the possible migration path of DNAPLs.
