This report presents the results from the analysis performed on one sample submitted by a representative of Energy Northwest. The sample was analyzed for the presence or absence of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) using USEPA Method 1613B. The estimated detection limits (EDLs) were based on signal-to-noise measurements.

The isotopically-labeled TCDD internal standard in the sample extract was recovered at 27%. Except for one low value, which was flagged "R" on the results table, the labeled standard recoveries obtained for this project were within the target ranges specified in Method 1613B. Also, since the quantification of the native TCDD was based on isotope dilution, the data were automatically corrected for recovery and accurate values were obtained.

A laboratory method blank was prepared and analyzed with the sample batch as part of our routine quality control procedures. The results show the blank to be free of 2,3,7,8-TCDD at the reporting limit.

Laboratory spike samples were also prepared using clean reference matrix that had been fortified with native standard material. The results show that the spiked native TCDD was recovered at 105-114% with a relative percent difference of 8.2%. These results were within the target ranges for the method. Matrix spikes were not prepared with the sample batch.
