It summarizes <br /> LLNL regulatory compliance activities and reports results of z <br /> environmental monitoring. This Environmental Community Letter <br /> offers a summary overview of the report. rt <br /> The 2003 Environmental Report represents the collection and analysis <br /> of several thousand environmental monitoring samples. These <br /> samples are taken from the air, water, and wastewater discharges <br /> from two sites. The main site is located in Livermore, California. <br /> The other is Site 300, an experimental test facility, located near <br /> Tracy, California. Samples are also taken from vegetation, wine, and Environmental monitoring <br /> soil on site and in surrounding communities. of LLNL operations in 2003 <br /> Many different assessments are made from these samples. indicates no adverse impact <br /> For example, some groundwater samples may be assessed for 50 to public health or the <br /> different chemicals or characteristics. environment. <br /> Specific Monitoring the highest concentration of released daily from all stationary <br /> Activities plutonium for all ambient sources in the Bay Area. <br /> air sampling locations at the <br /> Livermore site, Site 300, and Approximately 101 kilograms <br /> AIR MONITORING surrounding areas was 0.009% per day of regulated air <br /> Air is monitored for of the federal standard. pollutants (including nitrogen <br /> radionuclides at various oxides, volatile organics, sulfur <br /> locations on the Livermore site Emissions of nonradioactive oxides, particulate matter, <br /> and Site 300, throughout the air pollutants from LLNL carbon monoxide, and lead) are <br /> Livermore Valley, and in the operations in 2003 were also emitted from the Livermore site. <br /> Tracy area.
