This paper presents a case study of the first commercial use of cone penetrometer testing (CPT)/deployed laser induced fluorescence (LIF) to address the following objectives at a creosote DNAPL site. The objectives of the investigation using CPT/LIF were to: quickly and cost effectively delineate the horizontal and vertical extent of creosote DNAPL in soil/groundwater; delineate/differentiate creosote DNAPL constituents within the extent of DNAPL; delineate dissolved-phase versus free phase DNAPL compounds in the subsurface. The complexity of investigating the extent of creosote DNAPL magnifies the time and cost of the application of conventional investigative techniques. The application of CPT/LIF at the subject site allowed a comparison between CPT/LIF and more conventional investigative techniques. If the objectives were achieved in a shorter time-frame, and at a lesser cost than traditional methods, then the CPT/LIF method would be confirmed as a viable, field-scale technology for investigating appropriate wood-treating sites.
