Documentation of EMSL-LV (Environmental Monitoring Systems Laboratory-Las Vegas) Contribution to Dallas Lead Study

摘要

During the summer of 1982 the U.S. Environmental Protection Agency (EPA), conducted a comprehensive multimedia environmental monitoring program in the vicinity of two secondary lead smelters located in Dallas, Texas. This monitoring program, which was conducted within a 1 mile radius of the two smelters, included a major soils investigation and the collection and analysis of approximately 3,000 soil, 1,000 blood, and 750 dust samples. Approximately 250 vegetation samples were also collected. For this study EMSL-LV was requested to provide documentation and guidance for the quality assurance/quality control (QA/QC) program, and to provide the analytical methods and soil sampling procedures protocols. The results of this soil monitoring strategy plus the protocols, reports and pertinent documentation provided by EMSL-LV for the Dallas Lead Study are presented.
