Capping is a technology that covers contaminated sediment with material to isolate the contaminants from the surrounding environment. Cleanup teams can use capping alone or combine it with other cleanup methods. The covering material isolates contaminants from the surrounding water, which helps reduce their movement, availability, and potential harm to aquatic life.
The Sediment Cap Chemical Isolation Guidance (SD-1, 2023) provides a framework for the design, construction, modeling, and long-term monitoring of sediment caps, with a focus on their chemical isolation function. Intended for regulators, stakeholders, consultants, responsible parties, and site owners, it serves as a supplement to the Contaminated Sediments Remediation (CS-2, 2014) guidance and expands on considerations for implementing and maintaining effective sediment cap remedies.
