Vapor space characterization of waste Tank 241-C-111 (in situ): Results from samples collected on 6/20/94
This report describes inorganic and organic analyses results from in situ samples obtained from the headspace of the Hanford waste storage Tank 241-C-111 (referred to as Tank C-111). The results described here were obtained to support safety and toxicological evaluations. A summary of the results for inorganic and organic analytes is listed in Summary Table 1. Detailed descriptions of the results appear in the text. Quantitative results were obtained for the inorganic compounds ammonia (NH{sub 3}), nitrogen dioxide (NO{sub 2}), nitric oxide (NO), hydrogen cyanide (HCN), and water vapor (H{sub 2}O). Sampling for sulfur oxides was not requested. Organic compounds were quantitatively determined. Five organic tentatively identified compounds (TICs) were observed above the detection limit of (ca.) 10 ppbv, but standards for most of these were not available at the time of analysis, and the reported concentrations are semiquantitative estimates. In addition, the authors looked for the 40 standard TO-14 analytes and observed 39. None of these compounds were above the 2-ppbv calibrated instrumental detection limit. However, it is believed that the detection of dichlorodifluoromethane and methyl benzene are real at these low concentrations. The five organic analytes with the highest estimated concentrations are listed in Summary Table 1. The five analytes account for approximately 100% of the total organic components in Tank C-111.
