Lawrence Livermore National Laboratory’s (LLNL’s) Annual Site Environmental Report provides the results of environmental monitoring, a summary of the effects of LLNL operations on the environment, a record of LLNL’s compliance with environmental standards and requirements, and a description of LLNL’s environmental protection and remediation programs. The report is prepared for the U.S. Department of Energy by the LLNL Environmental Functional Area. The report is commonly referred to as the ASER (Annual Site Environmental Report).
