IN SITU SOLIDIFICATION (ISS) OF RIVER SEDIMENTS: PILOT DEMONSTRATION AND DISCUSSION OF ISS AS A REMEDIAL ALTERNATIVE TO DREDGING AND CAPPING
Jansen, P., M. Sabulis, and J. Clock.
Remediation Journal, Vol 26 No 2, 25-49, 2016
In the first successful use of ISS techniques to solidify underwater sediments containing coal-tar NAPL from a former manufactured gas plant, cementitious grout was mixed with the sediments in situ to create a monolith that immobilized the contaminants, significantly decreased the hydraulic conductivity, and vastly decreased contaminant leaching potential of the sediments. The project utilized a customized marine platform (modular floats, tug boats) and full-scale ISS equipment (auger rig, silos). Operational parameters were varied to provide a range of data for use in planning future ISS projects on the water.
