USA performs MEC services, both inside and outside the continental United States (CONUS/OCONUS) to identify potential risks and develop appropriate response alternatives to reduce human risks associated with MEC and munitions constituents (MC). By working within an accepted, consistent framework, we are able to streamline project activities, make more consistent decisions, and have the necessary documentation to support those decisions. USA focuses on hazard management choices made during site evaluation and cleanup of MEC under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). In addition, our MEC characterization responses fulfill the National Contingency Plan requirement for site-specific risk assessments under CERCLA.

Examples of our MEC and MC core capabilities include:

  • Preliminary Assessments
  • Site Inspections
  • Remedial Investigation/Feasibility Study (RI/FS)
  • Record of Decision
  • Remedial Design/Remedial Action
  • Remediation and Disposal
  • Operational Range Clearance/Maintenance
  • Construction Support
  • Geophysical Services
  • Underwater UXO Services
  • Community Education

Field Demolition Video

In this video, USA's UXO Technicians successfully perform a consolidated, continuous demolition shot.  The demo event used a flex linear shaped charge, combined with 350-millisecond delay detonators, to treat sixty 20-mm HEI projectiles.
