Environmental report for 1991

As part of its commitment to environmental compliance and accountability, LLNL prepares this report each year to communicate the results of monitoring and compliance activities. Analytical data are produced from sampling of air, sewage effluent, groundwater, surface water, soil, vegetation and foodstuff, and through measurement of environmental radiation. The Environmental Protection Department performed more than 150,000 analyses of environmental samples during 1991. This Executive Summary provides a comprehensive synopsis, organized along the general outline of the report, and furnishes an overview of the supporting methodologies, data, and findings that are presented in the chapters that follow.
