Statistical Analysis of F001-F005 Spent Solvent Concentrations in Tank Wastes

[摘要] A large quantity of mixed waste is generated at the Hanford Site from maintenance, sampling, analysis and research performed on tank waste. The majority of this waste contains only trace residues of actual tank waste and would be expected to contain a low concentration of spent solvent constituents. This paper gives a statistical methodology to find estimates of the mean concentration, as well as the 90th and 95th percentile of the concentration distribution, along with their respective upper 95th percent confidence limits, for each of the seven constituents of concern. This method is suitable when a large percentage of concentrations are reported as non-detects.
