Capping is a commonly selected approach for the remediation of subaqueous contaminated sediments. This guidance provides a framework for the design, construction, and long-term monitoring approach for the chemical isolation function of sediment caps. It is intended for regulators, stakeholders, consultants, responsible parties, and owners of contaminated sediment sites where sediment capping has been selected as a remedy.
As a supplement to the ITRC’s 2014 Contaminated Sediments Remediation guidance document, SD-1 provides more details regarding the design, construction, modeling, and long-term monitoring and maintenance of the chemical isolation.
