This powerpoint presentation begins by listing the general characteristics of metallic pipe
surfaces, followed by general information on iron corrosion, oxidant research, practical issues of contaminant
accumulation, particle mobilization, desorption, nitrification issues, aluminum interactions, and a table of LSL Examples. The presentation has a second section called Domestic/Commercial Plumbing that presents major issues that include:
prevalence and stability of PbO<sub>2</sub> deposits;
serious gaps in knowledge of phosphate solids;
gaps remain for Pb hydroxycarbonate solubility;
long-term leaching
factors responsible for copper pinhole leaks; role of Mn, Fe, Al, Ca and other deposits on surface;
what is the kinetic or solubility role of non-carbonate
anions, such as chloride and sulfate; solubility and kinetics of Fe, Mn, Cu, Al, Pb silicates; and,
the relationship of pipe age and standing time on copper
levels.
