Publisher Summary This chapter illustrates the future work that is necessary in AUES sites and the role of the states in environmental remediation of military sites. The AUES was a very complex site and the primary focus of the investigation under the District of Columbia's direction was to find the burial sites containing CWM and explosive or chemical ordnance. As a direct and proximate result of the District's work, 655 shells and 220 bottles containing Lewisite, mustard, bromine compounds, and other chemical warfare agents and precursors have been found. A secondary objective was to find areas of contamination. Approximately 10 percent of the properties have been found to contain elevated levels of arsenic, and about 15 required time-critical removal actions. Most of the 660 acres already identified are probably free of contamination or buried ordnance. Needless to say that this is only a step towards the decontamination of sites. However, additional work still remains to be done at these sites, such as conducting geophysical surveys on at least the first three priority tiers of properties and intrusive investigation of all unexplained anomalies. This is necessary because there are still 4301 shells missing from the AUES inventory.
