The purpose of this manual is to provide Program policy and oversight for the maintenance of Quality Assurance (QA) and Quality Control (QC) within the Environmental Survey and Site Assessment Program (ESSAP) of Oak Ridge Institute for Science and Education. This manual describes administrative systems, as well as specific quality control procedures, which apply to all functional groups in ESSAP. The sites surveyed under this program are primarily those where residual contamination from previous operations may pose a potential risk to the environment or to the health and safety of those in the immediate vicinity. Other major activities include environmental assessments, training related to decommissioning survey activities, effluent sampling and monitoring, special laboratory analyses, program appraisals and document reviews, consulting on environment-related topics, and technical assistance for guideline development. The methodology for performance of particular field and laboratory activities is presented in the ESSAP Survey Procedures Manual and the Laboratory Procedures Manual.
