The USDA Agricultural Research Services and the University of Maryland, College Park, collaborated to design a biowall to remediate TCE-contaminated groundwater at the Beaverdam Road Landfill OU of the Beltsville Agricultural Research Center Superfund site in Beltsville, MD. A hybrid adaptive management strategy incorporated up-to-date information into the remediation plan throughout the process. Lab experiments and a historic data assessment were conducted with a monitoring plan to modify the monitoring and biowall construction plans during the design process. The project's scope grew to include investigations of the soil microbial community for future structural biostimulation and bioaugmentation activities. While the biowall has reduced the concentration of TCE to levels at or below the maximum contaminant level, work is ongoing to improve the functionality of the biowall and address emerging challenges. https://iopscience.iop.org/article/10.1088/2515-7620/ab2de4/pdf Locate the 2018 Five Year Review and monitoring reports by selecting BARC 27 (Beaverdam Road Landfill) at https://cercla.ba.ars.usda.gov/advancedsearch.
