Since 1917 until base closure in 1994, portions of the Fort Ord property were used by infantry units for maneuvers, target ranges, and other purposes. Military munitions such as artillery and mortar projectiles, rockets, and guided missiles; rifle and hand grenades; land mines; pyrotechnics; bombs; and demolition materials, were fired into, fired upon, or used on the facility. As part of the comprehensive environmental investigation of the former Fort Ord under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), several literature reviews and associated field investigations were conducted. During this process, the Army has responded to documentation or site-specific discoveries related to the potential presence of chemical warfare material (CWM). The purpose of this technical memorandum is to describe the circumstances surrounding each of these events and subsequent actions taken to resolve them. The comprehensive environmental investigations have not found any evidence of presence or use of chemical weapons at Fort Ord. Information from various document reviews and literature searches indicate no ordnance-related CWM were stored or used at Fort Ord. Chemical agents were used at Fort Ord in the form of Chemical Agent Identification Sets (CAISs) (Army, 1993), which were used to train soldiers to recognize and protect themselves from chemical agents. These CAISs contained dilute solutions of chemical agents in small (one-ounce), hermetically sealed glass containers. Information regarding discovery and disposition of CAISs at Fort Ord are presented in Sections 2.1 and 2.6. The investigations documented in this report show that, other than the CAISs mentioned above, no CWM or non-stockpile chemical material (NSCM), have been found on the Fort Ord. Non-Stockpile
