An investigation of the chemical composition of mining and smelter wastes and the composition's effect on the bioavailability of lead, as predicted by geochemical modeling, will be presented. Chemical sequential extraction was used to quantify the different types of chemical bonding in the samples. X-ray analysis of the samples and their sand, silt and clay fractions was also performed. The results from these laboratory investigations were compared with geochemical modeling. Modeling predictions and laboratory results were similar.
