10th International Conference on the Remediation and Management of Contaminated Sediments, 11-14 February, New Orleans, Louisiana, 25 slides, 2019

Sediments in Kendall Bay were contaminated with PAHs and total recoverable hydrocarbons from the former Mortlake operations on the bay's shore. In situ stabilization/ solidification (ISS) was selected as the remediation technology, which reduced the need to move contaminated material for off-site treatment and disposal and the potential for odor emissions associated with traditional dredging approaches. A Phase 1 lab treatability study identified the optimal additive mix design required to meet the project performance criteria, including unconfined compressive strength, contaminant leachability, and hydraulic conductivity. A Phase 2 pilot study took place at a location in Kendall Bay, selected based on similar physical sediment properties and contamination as the remediation areas. The Phase 3 work involved the construction of a 1.5 m-thick ISS raft to remediate contaminated sediments and 8 deeper ISS columns for structural support and constructability of the raft within one of the remediation areas. Using multiple lines of evidence, the trials demonstrated the successful application of ISS for the remediation of contaminated sediments in Kendall Bay. The project will now progress to full-scale remediation of contaminated sediments. https://www.battelle.org/docs/default-source/conference-proceedings/2019-sediments-conference-proceedings/b11.-in-situ-stabilization/b11_1300_-77_clutterham.pdf?sfvrsn=e5079f2e_2 [Note: It might be necessary to copy/paste the URL into your browser.] More information: http://jemena.com.au/documents/remediation-projects/kendall-bay/planning-approval-documents/3-ssd-6701-assessment-report-signed.aspx.
