One technology field tested under the SITE research program was the HAZCON stabilization process. This process treats the waste by mixing it with portland cement, water (if needed) and chloranan, a proprietary chemical. By comparing the chemical and physical properties of the waste before and after treatment, this field demonstration developed data on the strength and leaching potential expected after treatment from a range of waste characteristics. Six wastes at the Douglassville, PA Superfund Site, containing up to 25% organics and 2% lead, were treated and evaluated. The physical strength (200 to 1500 psi) and durability, i.e., long-term stability, of the stabilized wastes were good. Even in wastes with high levels of organics (25%), stabilization of lead was very successful. Leaching results determined that lead concentrations dropped by factors between 100 and 1000 after treatment. Stabilization of organics, however, achieved mixed results. Leachate concentrations generally did not change between treated and untreated samples. It could not be determined if this was a failure of the treatment process or an anomaly of the test procedure.
