This report is intended to aid the Weldon Spring Project Management Contractor in screening two vitrification technologies developed by Pacific Northwest Laboratory (PNL) for the remediation of raffinate sludges and contaminated soils at the Weldon Spring site in St. Charles County, Missouri. A previous report (Koegler, Oma, and Perez 1988) described the joule-heated ceramic melter (JHCM) and in situ vitrification (ISV) processes and their applicability to remediation of the Weldon Spring site based on existing information and previous PNL experience with similar wastes. Subsequent treatability tests and product analysis were conducted by PNL to further evaluate the JHCM and ISV processes. The treatability tests involved laboratory and bench-scale tests with actual raffinate sludge and uncontaminated soil from the Weldon Spring site. The vitrified product from the JHCM and ISV treatability tests was analyzed for a wide range of characteristics, including durability (leach resistance), strength, and toxicity. Both the process performance test and product quality were used to assess the two PNL vitrification technologies to determine their effectiveness, implementability, and cost. 11 refs., 16 figs., 23 tabs.
