The rapid and under-regulated development of industries in the past has left major contamination problems in several coastal and estuarine areas. Such contamination from historical chemical releases (industrial discharges, storm sewers, wastewater, landfill runoff, and leachate) severely impairs the ecological and recreational functions of the estuary/ocean. The discharged contaminants typically adhere to the fine sediments and settle in low-energy zones, which are conducive to deposition. Once settled, such sediments can exert significant oxygen demand, reduce benthic diversity, and result in poor water quality.

Contaminated sediment removal can be expensive because a high degree of efficiency and reliability is required in such operations. Capping is an attractive, nonintrusive and cost-effective method of remediating contaminated sediments in rivers and harbors, where draft restriction is not a major concern. The same physicochemical properties and hydraulic conditions that favored...
