Thirty-three inactive waste storage tanks, currently managed by the ORNL Remedial Action Program (RAP), are to be characterized in preparation for final closure/decommissioning to meet environmental, safety, and long-term surveillance objectives. To date, 30 of these tanks have been characterized. Aqueous liquid and sludge samples from the waste storage tanks were subjected to modified U.S. Environmental Protection Agency SW-846 and Contract Laboratory Program methodology to determine Target Compound List and other Appendix VIII organic compounds. With few exceptions, low microgram-per-liter (liquids) and milligram-per-kilogram (sludges) concentrations of regulatory organic compounds were found, and the major species were alcohols, ketones, chlorinated hydrocarbons, and tributylphosphate. The goal of the inorganic analytical support for the inactive tank-sampling and characterization task is to provide the data necessary to meet both regulatory and engineering treatability requirements. To date, the inorganic tank content measurements have included metals, radionuclides, anions, and several physical measurements. Determination of the RCRA status of the tank contents depends upon the hazardous characteristics of the waste and upon a comparison of the waste constituents to the list of RCRA hazardous wastes contained in the Code of Federal Regulations. Tanks that contained no RCRA characteristically hazardous or RCRA listed organic constituents were W1, W2, and T30. At this stage of analysis, the remaining tanks should be considered as containing RCRA waste. Figures and tables are included in this report.
