This slide presentation outlines a study on Pb release from end-use plumbing components in Seattle Public Schools. The presentation begins with background information on the Seattle Public School District and its issues with water quality. The objectives of this study were: to determine Pb release levels from end-use plumbing components and fittings in Seattle Public Schools. The approach included: field sampling - "sequential" sampling indicated that new end-use plumbing contributed elevated Pb levels; and, laboratory testing - conducted to asses the relative contribution of individual components. Results of both tests are provided and Discussion Topics include: Estimated Range of Pb Contributions from End-Use Plumbing Components; and, "Pre-Conditioning" of New Bubbler Heads. Conclusions and recommendations are given. Includes 3 references, tables, figures.
