Abstract: Shallow Geophysics for Investigation of a Creosote Contaminated Site in Central Ohio

Electromagnetic (EM) and Ground penetrating radar (GPR) surveys were conducted at an industrial site that formerly operated as a creosote wood treating facility in order to accomplish two objectives: 1) to delineate the extent of creosote contamination at the site, and 2) to locate buried pipes, tanks or other subsurface features that could lead to further contamination if ruptured during remediation. Data interpretations were confirmed by exploratory trenching and soil sampling subsequent to the completion of this study. EM data were useful for mapping the extent of creosote within surficial soils. The GPR data proved successful in locating back-filled trenches and pipes at the site, as well as vaults and a pit filled with pure creosote product. Both parallel dipole (co-pole) and crossed dipole (cross-pole) data were collected during the GPR survey. Cross-pole data were more useful for site characterization at this location, as images produced using co-pole data had a poor signal to noise ratio due to site conditions.
