This week crews focused on loading previously excavated soil into drums. Composite samples of the soil were taken for further analysis. Crews also performed some hand excavations and found small amounts of American University Experiment Station-related debris.
We continue to see low level readings for possible lewisite on the MINICAMS (near real time continuous air monitoring system) at the pre-filter (inlet to the Chemical Agent Filtration System, or CAFS). However, the DAAMS (Depot Area Air Monitoring System) tube continue to be non-detect for lewisite. There continues to be no risk to the public due to these readings. All of our engineering controls are working as designed, with multiple layers of protection. We are continuing to monitor this situation.
Next week crews will continue excavation in the area adjacent to the former front porch.
Safety continues to be our number one priority at the site. Throughout every phase of the project, all necessary precautions are taken to ensure the safety of the site workers, the residents of the community, and those driving by. We will continue to keep you updated.
