Dogus Meric Presented on Sediment Stabilization during GeoPro Talk Webinar

Dogus Meric, Ph.D., P.E. (Illinois) presented "First-to-Field Mass Mixing In Situ Stabilization/Solidification Remediation in Uncharted Waters of Kendall Bay" during GeoEnviroPro's weekly Wednesday Tech Talk webinar, GeoPro Talks.

Dogus Meric is a Senior Environmental Engineer based in Illinois with more than 12 years of experience in the management and remediation of contaminated sediment sites. Dogus is a pioneer in sediment remediation technologies, including in situ stabilization/solidification (ISS) of subaqueous sediments and thin-layer sediment capping. In addition, he coauthored the ASTM International standard guidance document on corrective action objectives on sediment sites. In 2021, the Kendall Bay sediment remediation and Wollongong Gasworks remediation projects earned six awards, including the Edison Award for "Sustainable Change for the Good," Australasian Land and Groundwater Association Industry Excellence Awards for "Best Remediation Project," "Innovation that Advanced the Practice of Contaminated Site Remediation," and "Best Regional Remediation Project."

GeoPro Talks are a series of short weekly webinars that present specific topics related to environmental sciences. Each GeoProTalk is led by a senior specialist who has spent years in the field gathering experience and knowledge. GeoEnviroPro serves environmental scientists, engineers, experts, executives, and practicing professionals, keeping them current on best practices and innovations by offering webinars, workshops, and on-demand courses led by experienced environmental professional leaders in their fields.

Abstract

Once home to the largest manufactured gas plant (MGP) in the southern hemisphere, the former MGP site at Kendal Bay, Australia was remediated and developed for medium density residential use almost two decades ago. The New South Wales Environmental Protection Agency declared the area a remediation site, and the owner subsequently prepared a Voluntary Management Proposal for remediation of sediments within the adjacent Kendall Bay. These sediments are impacted with hydrocarbons (polycyclic aromatic hydrocarbons, total recoverable hydrocarbons, and BTEX) as a result of former manufactured gas plant operations. Residential land use surrounding the bay presented challenges to development of a remedial approach, since the approach needed to address the impacted sediments while minimizing impacts to the residents. To minimize odour and truck traffic, in situ stabilization/solidification (ISS) of impacted sediments followed by capping was selected as the preferred remedial approach, rather than a traditional dredging approach. This presentation will describe technical and design approaches that quickly moved this project from laboratory bench-scale treatability study to full-scale field application; it presents invaluable lessons learned in overcoming many unexpected technical challenges.
