The purpose of this study was to determine the optimum phosphate treatment method to stabilize lead contaminated soil from a firing range. Seven different phosphate sources at five different concentrations were added to soil collected from a firing range on a military base. A series of tests were performed to determine a generic phosphate treatment method. The selected generic phosphate treatment was compared to an untreated control soil sample and to four commercially available treatments provided by invited vendors selected from industry. The four vendors processes, control, and generic treatments were subjected to a series of physical and chemical tests at 0, 14, and 28 days of curing time to determine the effectiveness of each treatment. The generic treatment using Hydroxyapatite developed in the MSU laboratory was competitive with three vendors? treatments. The fourth vendor?s treatment was more effective at reducing the lead leachability of the contaminated soil.
