ABSTRACT: Volume estimation and three-dimensional mapping of salt-impacted soils is an integral part of both remediation and risk
management activities in order to create accurate project budgets, alternative remedial options, and to properly
characterize the site for risk management. This extended abstract reviews a case study documenting the process and
final results after the combined acquisition and interpretation of novel geophysical survey data using innovative
techniques for mapping chloride contaminated soils in the vicinity of a historical pipeline release. The integration of
geophysical data from the OhmMapper and EM31 systems with borehole measured concentrations and conductivities
enables quantifiable constraints for the geophysical data to be used. For this case study, a start to finish methodology
can be recognized, highlighting impacted soil volume estimates compared to actual impacted soil volumes removed from
site during a remedial excavation to achieve site closure.
