Sub-aquatic sediment is covered with capping material by a capping system comprising a template barge and a spreader barge. While the spreader barge is distributing capping material, the template barge guides the spreader barge as it systematically moves over a pre-defined sediment capping region. The spreader barge comprises a spreader pool in which a broadcast spreader accurately and evenly distributes capping material within the pool, which then sinks to the sediment. The capping material is distributed with minimal disturbance to the sediment.

Contaminated fine sediment is removed from surfaces beneath a body of water by a shrouded, self-cleaning, wheel-guided, open suction attachment for a swinging ladder suction dredge with articulating capabilities. The attachment comprises a wheel-guided, suction assembly in which the slurry is contained in a shroud. The shroud is attached to a head plate, and is designed to both enclose the solid particles suspended as a result of the removal operation, and to direct the suspended material to the mouth of the suction pipe. Inside the area surrounded by the shroud is a gatling plate rotated by a hydraulic motor mounted just above the shroud and head plate.
