ABSTRACT:
A method is disclosed for reducing the leaching of lead from a lead bearing material or waste. The method includes contacting the material or waste with a water soluble phosphate and a complexing agent, wherein the complexing agent is at least slightly water soluble, whereby a lead product is formed which is less soluble than the lead originally in the material or waste, thereby reducing the leaching of lead from the material or waste as determined by a leach test performed on the material or waste.
