ODMDS Search

This data table provides a summary of disposal history at open, closed, and inactive ODMDSs. The data are grouped by U.S. Army Corps of Engineers (USACE) Districts. The total disposal for all sites within each USACE District is displayed at the end of each group. Total disposal will dynamically change based on how the data are filtered. To view disposal history for a specific ODMDS click on the disposal event count. Disposal has not occurred at all ODMDS. Select a USACE District or U.S. Environmental Protection Agency (USEPA) Region to view all ODMDSs and their disposal history for the selection. Disposal history for all years will be returned. Use the search box above the table for more specific searches.
