The pilot study results are compelling, the regulators are enthusiastic, and the potential to limit environmental damage and remediation costs is real. In-situ remediation is increasingly used as part of an overall remedy, especially for sites in areas where regulators, site managers, and scientists understand the benefits of the technology, and where responsible parties seek viable cost-effective alternatives to excavation and dredging. So why isn’t it used at every site contaminated with PCBs, Dioxins, PAHs, and pesticides? As with many questions, the answer is “it depends.” In this webinar, we’ll share our insights and experience regarding this question. Specific topics will include:
- An overview of the history of in-situ sediment remediation technology with an emphasis on the use of activated carbon for organic chemicals such as PCBs.
- Demonstration of how in-situ sediment remediation technology fits into various regulatory frameworks.
- Exploration of the factors that guide decisions related to the use of in-situ remediation by itself or as one part of a remediation strategy.
- Case studies to illustrate the efficacy of in-situ sediment remediation technology.
- Description of the methods used to monitor success, including passive samplers, which differ from typical post-remediation monitoring methods.
- Discussion of what success means and what to expect in the long-term for remediated sites.
The webinar will enable executives, managers, and legal teams to be better prepared to discuss and critically evaluate remedies that include in-situ remediation. The slide package will be made available to those that attend and will include links to key resource documents.
