Description:
The major objective of the HAZCON Solidification SITE Program Demonstration Test was to develop reliable performance and cost information. The demonstration occurred at a 50-acre site of a former oil reprocessing plant at Douglassville, PA containing a wide range of organic and heavy metal contaminants. The HAZCON process mixes the hazardous waste material with cement, a proprietary additive called Chloranan, and water. The Chloranan is claimed to neutralize the inhibiting effect that organics normally have on the hydration of cement The technical criteria used to develop the effectiveness of the HAZCON process were contaminant mobility, based on leaching and permeability tests; and potential integrity of solidified soils, based on measurements of physical and microstructural properties. Extensive sampling and analyses were performed showing (1) the concentration of the organics were the same in the TCLP leachates of the untreated and treated soils, (2) heavy metals reduction was achieved, and (3) structural properties of the solidified cores were found to indicate good longterm stability. This Summary was developed by EPA's Risk Reduction Engineering Laboratory, Cincinnati, OH, to announce key findings of the SITE Program demonstration that is fully documented in two separate reports.
