Exceeding the <br />holding time will not invalidate characterization if the waste exceeds the <br />regulatory level. <br />9.0 METHOD PERFORMANCE <br />9.1 Precision resu'.ts for Seri-voiatiles and metals: An eastern soil <br />wicti high organic content and a western soil with low organic content ware used <br />for the semi-volatile and metal leaching experiments. Both types of soil were <br />analyzed prior to contaminant sp?king. The results are shown in Table 6. The <br />concentrations of contaminants leached from the soils were consistently <br />reproducible, as shown by the low relative standard deviations (RSDs) of the <br />recoveries (ganerally less than 10 Y. far mast of the compounds). <br />9.2 Precision results for voiatiles: Four different soils were spiked <br />and tested for the extraction of voiatiles. Soils One and Two were from western <br />and eastern Superfund sites. Soils Three and Four were mixtures of a western <br />soil with low organic content and two different municipal sludges. The results <br />are shown in Table 7. Extract concentrations of volatile organics from the <br />eastern soil were lower than from the western soil. Replicate teachings of Soils <br />Three and Four showed lower precision than the leachates from the Superfund <br />soils. <br />1312 - 20 Revision 0 1 <br />November 1992 <br />
