The objective of this presentation is to discuss and demonstrate the applicability of beneficial use technologies for the management of contaminated materials at in-water remediation sites. Beneficial use can provide site improvements and cost savings to clean-up projects while also achieving remediation objectives and should be evaluated for applicability as a remediation technology during site planning and design.
