A treatability test using the In Situ Vitrification (ISV) process was successfully completed on explosives-contaminated soils from the former Nebraska Ordinance Plant (NOP). Contaminated soil from various regions of the plant were gathered, homogenized, and then submitted to Geosafe for testing. ISV is a thermal treatment process in which contaminated soils are heated to melting by the use of electrical current. Upon cooling, the melted soil forms a glass and crystalline (vitrified) product. Organic compounds present in the soil predominantly pyrolyze (thermally decompose into elemental hydrogen and carbon); the pyrolysis products are eventually oxidized when they reach the oxygen-rich hood plenum area at the soil surface. Non-volatile compounds are permanently immobilized within the vitrified product, and volatile heavy metals are removed from the off-gas stream by a gas treatment system. The treatability test had the primary objective of determining the effectiveness and feasibility of treating the explosives-contaminated soil using the ISV technology.
