The Department of Defense, specifically the U.S. Army Combat Capabilities Development Command - Soldier Center (DEVCOM-SC), is seeking innovative solutions for the rapid biological decontamination of water to ensure safe drinking for military personnel. The objective is to identify technologies that can provide portable, effective methods for producing potable water in austere environments, thereby enhancing soldier survivability and hydration during combat operations. This initiative addresses the limitations of current water purification methods and aims to develop systems that meet EPA performance standards while being lightweight, low-power, and capable of operating in extreme temperatures. Interested parties are invited to submit Broad Agency Announcement (BAA) preproposals by February 28, 2025, at 5:00 PM EST, to the designated contacts, Dr. Shannon McGraw and Patrick Marek, via email.
