This shipping canal in Illinois had accumulated contaminated oil sediments from a decommissioned refining facility. A pilot study was initiated to evaluate performance of hydraulic dredging and subsequent Geotube® dewatering of the sediment. Over an 8 day period 400 linear feet of Geotube® was pulse filled to capacity. WaterSolve, LLC provided the tubes, polymer, make-down equipment, and technical service to perform this study.
