Area of Science:

  • Environmental Science
  • Chemical Engineering
  • Military Engineering

Background:

  • High explosive mass residue from military munitions poses an environmental risk.
  • Contamination of soil, surface water, and groundwater is a significant concern.
  • Previous sampling methods have had limited success due to complex residue dispersion patterns.

Purpose of the Study:

  • To quantify, understand, and remediate explosive residue on active firing ranges.
  • To simulate particle dispersal patterns for high- and low-order explosions.
  • To provide detailed data for soil and water transport models and optimize sampling techniques.

Main Methods:

  • Utilized experimental particle data from 155-mm howitzer munition detonations.
  • Simulated particle dispersal for hypothetical firing ranges.
