The SERDP and ESTCP Weapons Systems and Platforms Program Area initiated an effort to develop a strategy to eliminate >90% of hexavalent chromium (Cr⁶⁺) and cadmium (Cd) in use at Department of Defense (DoD) maintenance depots over the next five years. To that end, the research team visited Oklahoma City Air Logistics Complex (OC-ALC) on 5-6 May 2015, as a first step in the preparation of this OC-ALC Implementation Plan.
