The sustainability of the DoD’s operational ranges is crucial to maintaining the readiness of the military forces and developing and testing improved weapon systems. SERDP and ESTCP convened a technical exchange meeting to (1) inform representatives from the range management and assessment communities of applicable technologies developed by SERDP, ESTCP, and the Army Environmental Quality Technology Program and (2) identify technology needs of the range management and assessment community that could be addressed through additional research and development efforts.  Two breakout sessions facilitated discussions of the current state of the science and identification of data gaps that could be addressed through additional RDT&E activities.
