ABSTRACT:
A method is disclosed for reducing the leaching of lead from a lead bearing waste, The method includes contacting the 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 waste, thereby reducing the leaching of lead from the waste as determined by a leach test performed on the waste.
