Confined Aquatic Disposal (CAD)

Confined Aquatic Disposal (CAD) is an environmental management method used to safely dispose of contaminated sediments from waterways. In CAD, the contaminated material is placed within a specially designed area, often using a containment structure. This area is usually situated in deeper water where the sediment can be isolated from the ecosystem, reducing the risk of contamination spreading. Over time, natural processes help to encapsulate and stabilize the materials, minimizing environmental impact. CAD is a controlled approach, balancing the need for sediment removal with the protection of aquatic habitats.
