The methodology utilized in the LAFB records search began in September 1984 with a review of past and current industrial operations conducted at the base. Information was obtained from available records, such as shop files and real property files, as well as interviews with past and current base employees from the various operating areas. The next step in the activity review was to determine the past management practices regarding the use, storage, treatment, and disposal of hazardous materials from the various operations on the base. A ground tour of the identified sites were then made by the ESE Project Team to gather site-specific information. A decision was then made, based on all of the above information, regarding the potential for hazardous materials contamination at any of the identified sites.
