Fort McCoy Contracts for UXO Wide Area Assessment

Fort McCoy, Wisconsin  The installation recently awarded a contract to Battelle for a wide area assessment of the Badger Drop Zone to search for UXO. According to the Army, a review of historical records associated with the site indicate that the drop zone area was used as an impact area from approximately 1905-1972. The survey will cover approximately 800 acres including Range 53, a former mortar impact range used during the 1950s. Reportedly the area has been surface cleared of UXO in the past but concerns over the potential for UXO to migrate during the freeze / thaw cycles necessitated the need for the survey. The contractor will use a helicopter mounted system to survey the area.

The exact dates of the survey are not known. If you have information on the survey including the specific technologies used, survey dates, or results please submit them as a comment for others to view.

Jerry L. Hodgson, P.E.'s Gravatar This effort should not be called Wide Area Assessment (WAA). A helimag survey on 800 acres of a
known impact area is either characterization and/or detection. WAA is utilized to assess 10's to 100's
of thousands of acres with the major objectives of identifying unknown areas of past military munitions
use and defining presumptively clean areas. The Omaha District and their contractor Sky Reseach, has
performed WAA on over 750,000 acres, and to my knowledge the only ones to ever utilize WAA in a
production, real world application. If you would like additional details on WAA please feel free to contact
me.
