unweathered fly ash utilization for agriculture. Trace and heavy metals in fly ash may also percolate into the soil and pollute ground water. The solubility of these elements is less than ten percent. It has been observed in laboratory experiments on leaching potential that 5-30% of toxic elements, especially Cadmium, Copper and Lead, are leachable.
