Millions of acres of Department of Defense (DoD) closed, transferred and transferring ranges may contain munitions and explosives of concern (MEC) (General Accounting Office, 2001). It is usually necessary to conduct geophysical surveys to search for MEC at these ranges before they can be released from DoD control for other uses. The process of searching for and removing MEC should be carefully planned to follow a quality control process to achieve cleanup goals. After detected MEC have been removed, a confirmation survey of the cleaned areas may be conducted to increase confidence in the cleanup process. These confirmation surveys are the focus of this paper. One possible statistically-based approach for conducting a confirmation survey is to use “accept-on-zero” attribute compliance sampling (AOZ ACS) (Schilling 1978, 1982; Squeglia, 1994). This approach involves conducting an inspection or sampling of a random selection of n “units” from among the total number of units (N) for a site. For example, the site may be divided into N non-overlapping 200ft x 200ft land areas (grids), n of which are randomly selected and inspected for MEC (n
