Cost to date
The cost data presented are essentially planning data that can change significantly as additional information is gathered or work is performed on a property or project. Historical data have been included for older properties and projects from a previous Corps FUDS database. For these properties and projects, costs have not always been updated or even entered. In other cases, average costs, such as costs for the preliminary investigation phase, have been used by Corps districts as representative of all properties and projects in that district.
If no cost to date is shown or the amount shown is zero, then there have not been any cleanup activities. Because this category can include costs necessary to study and assess the property or project, incurring costs does not necessarily mean that cleanup itself has begun or that cleanup is even necessary.
