A rotating cylindrical containment tool that removes contaminated sediment and prevents the dispersion of contaminated sediments during excavation. The tool casing is rotated and is forced down into the sediment whereby the sediment rises up into the interior of the casing. Water flows into and out of the casing based on external and internal pressures. After the sediment rises into the cylindrical casing a feed auger assembly extending therefrom is utilized to deliver materials and/or cap the excavated void space in the sediment. Alternatively, the rotating containment tool prevents the dispersion of contaminated sediments and treats contaminated sediment in situ with treatment reagents, in the sub-aqueous environment.
