Description:
Since the implementation of the United States Environmental Protection Agency’s Lead and Copper Rule (LCR) in 1991, a great deal of research has been conducted on copper corrosion and the leaching of copper from materials in drinking water distribution systems. While important progress has been made, a number of gaps still exist, especially in the area of Cu(II) solubility (cuprosolvency) research. The objective of this study was to further examine the effects of water chemistry on the solubility and properties of newly precipitated Cu(II) solids. Specifically, the effects of pH, inorganic carbon (DIC), sulfate, silicate, orthophosphate, and polyphosphate were investigated.
