This powerpoint presentation begins by providing a brief overview of water chemistry impacting lead mineralogy, solubility, and particle properties. Study objectives were to: describe lead synthesis experiments conducted to model the impact of water quality on lead particles and solubility; develop a model system that can be used for lead solubility studies; and, understand how phosphates impact the morphology and solubility transformations with time. Synthesis and analysis of methods are presented, along with particle synthesis results for chlorine and age, orthophosphates, and polyphosphates. Presentation conclusions indicate the following: precipitation experiments provide a simple means of understanding fundamental interactions of lead mineralogy; morphological and surface analysis can help explain the results of studies that observed decreased lead solubility after disinfectant change (ORP) and the formation of Pb(IV) compounds in the absence of phosphates; addition of other types of phosphates impacted the mineralogy and transformation compared to the phosphate-free samples; chemical analysis associated with transformation and surface morphology will provide useful insight into dissolution of lead in water; and, lead pyrophosphates and other metal pyrophosphates could conceivably form in real DWDS and more work is needed to determine the kinetic and synthetic boundaries.
