2. Executive Agent – DASAI&E[ESOH] 2 National Defense Center for Environmental Excellence The NDCEE is operated for the DoD by Concurrent Technologies Corporation Executive Agent – DASAI&E[ESOH] 02/04 The Problem: Under Optimal Soil and Climatic Conditions n Frost heave (i.e., frost jacking) causes upward migration of UXO (cold regions) n Salt/Chemical heave may cause upward migration of UXO (hot, arid regions) n UXO is cleared to standard depths based on end-use n If UXO migrates to shallower depths, it will become a serious safety issue

Executive Agent – DASAI&E[ESOH] 4 National Defense Center for Environmental Excellence The NDCEE is operated for the DoD by Concurrent Technologies Corporation Executive Agent – DASAI&E[ESOH] 02/04 NDCEE Specific Tasks  Assess existing data and previous studies concerning UXO frost and salt heaving.  Identify existing models.  Conduct field and environmental chamber tests to determine potential UXO migration in soil using inert UXO targets (shapes) of different sizes, placed in different orientations. These targets will be monitored continuously for movement.  Document study by collecting all UXO movement, ambient air temperature, soil moisture content, temperature, and soil water potential. All aspects will be pictorially captured.
