Phosphate was applied at a molar ratio of P/Pb 4:1 with two-thirds of the P supplied by PR and one-third by PA. Four shooting range soils were incubated for 18h overnight in soil columns. Leaching/percolation was done in two stages with TCLP and SPLP fluids respectively. Even though there was a >90% decrease in Pb leached from all phosphate treated soils, the treatment effectively reduced TCLP Pb to below 5 mg/L in rifle 1 and rifle 3.    Soil properties such as clay, total Fe and total P contributed significantly to the reduction in TCLP-Pb leached after 18h of incubation even  though clay content was the only significant predictor at α= 0.05.  There was initially a fast release of Pb with TCLP fluid followed by a slow release in untreated shooting range soils. The metal release was positively correlated to the pH of the leachates suggesting a proton-induced mineral desorption and dissolution. Addition of phosphate sources changed the pattern of release probably due to immobilization of lead in the soil.
