POTENTIAL EFFECTS OF PHOSPHATE PRODUCTS ON LEAD SOLUBILITY IN PLUMBING SYSTEMS
Holm, T. R. AND M R. Schock*. POTENTIAL EFFECTS OF PHOSPHATE PRODUCTS ON LEAD SOLUBILITY IN PLUMBING SYSTEMS. JOURNAL OF THE AMERICAN WATER WORKS ASSOCIATION. American Water Works Association, Denver, CO, 83(7):76-82, (1991).
Lead concentrations in drinking water can be minimized by adjusting the pH and alkalinity. Such lead solubility controls, however, may be offset by other water treatment measures that inadvertently increase lead solubility, e.g., the adding of polyphosphate-containing products. Through the use of solubility computations, the authors of this article conclude that, at best, the application of polyphosphates for the specific purpose of leaad corrsion control entails considerable uncertainty and risk.
