||The goal of the current investigation was to survey and sample the full extent and magnitude of sediment contamination of the Minnesota Slip. Survey locations were accessed through the ice with a Laser Induced Fluorescence (LIF) tool, targeting 29 points spatially distributed throughout the Slip. Continuous LIF records were produced from depths ranging from 0 to 20 feet beneath the water-sediment interface. The results of this survey were then used to locate sites for eight sediment cores, from which 18 sediment samples were collected for laboratory analysis. These borings were extruded, sampled and submitted to chemical analysis for metals, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and various physical parameters.
