An Investigation of Plume Response to Soil Vapor Extraction and Hypothetical Drum Failure

Soil vapor extraction operation in 2015 and rebound testing through 2017 were successful in reducing the plume's mass and mitigating VOC migration toward the water table. However, the possibility that waste drums could fail and release VOCs could pose a challenge in the future. To explore the i...

Rappe, B. Three‐dimensional Dichloroethane Interim measure Tetrachloroethylene Soil vapor extraction operation in 2015 and rebound testing through 2017 were successful in reducing the plume's mass and mitigating VOC migration toward the water table. However, the possibility that waste drums could fail and release VOCs could pose a challenge in the future. To explore the impacts of drum failure, as well as the capabilities of SVE remediation, we simulated hypothetical contaminant release scenarios and subsequent SVE remediation. Three‐dimensional subsurface VOC behavior, including advection, diffusion, and plume interactions with topography, were simulated using the porous flow simulator Finite Element Heat and Mass Transfer. Simulations of future site conditions have allowed identification of “sentry” boreholes that can be monitored for early detection in case of drum failure. Sentry boreholes can also be used to set concentration thresholds above which SVE should be initiated. For the LANL site, simulations show that SVE can be started 3 yr following drum failure and remain a viable remediation tool. More broadly, the principles outlined in this work can be used to support remediation planning at other subsurface waste sites. Predictive models of future releases can be analyzed to set concentration threshold values, guide selection of sentry boreholes, and increase operational efficiency. https://acsess.onlinelibrary.wiley.com/doi/10.2136/vzj2018.04.0080 2020-11-08T03:11:20Z 2020-11-08T03:11:20Z 2019 BB 1539-1663 http://tailieuso.tlu.edu.vn/handle/DHTL/9704 en Vadose Zone Journal, Vol 18, Issue 1 (2019), pp.1-21
