The environmental cleanup industry continues to move towards implementation of in situ remediation technologies to take advantage of cost-savings over soil excavation and to overcome limitations inherent to pump-and-treat operations. However, in situ technologies present their own associated risks, including uncertainties in performance and potential release of secondary contaminants. Consequently, site-specific evaluations of in situ remediation technologies, a.k.a. treatability studies, are customary before full-scale implementation of a remediation strategy can occur.
In this webinar, we will introduce a new technology, the in situ Microcosm Array (ISMA), for conducting multiple treatability studies in saturated subsurface environments (in situ) at the same time, in the same well. The ISMA is a self-contained device that pumps groundwater directly from the formation to conduct multiple column studies in situ; all groundwater entering the device is stored and retrieved with the device at the end of the subsurface deployment, thereby eliminating the chance of adversely impacting the groundwater well and surrounding aquifer during small-scale in situ feasibility tests.
This webinar will provide the following information:
- Why do we need another tool for treatability studies?
- Design and functionality of the in situ Microcosm Array (ISMA)
- Treatments that can be tested using the ISMA
- Results generated and strategies for data analysis
- Case studies highlighting capabilities of the ISMA.
Participants will come away with an understanding of the needs and challenges of treatability studies for
remediation, of how the ISMA works, how it can address pertinent needs, and what kind of data are generated using this innovative diagnostic downhole device for remedial design.
