PbO, PbCO3, and Pb-3(OH)(2)(CO3)(2) were identified as primary corrosion products on lead coupons following three months of exposure to finished RO, surface and ground water by XRD and XPS. Based on these results, a Pb-3(OH)(2)(CO3)(2) Solid phase equilibrium model was used as a function of water quality, was modified using diffusion theory and accurately predicted lead release for a majority of field observations. SEM photographs revealed sulfate and chloride affected the surface structure of corrosion scales and lead release. (c) 2006 Elsevier Ltd. All rights reserved.
