TABLE 3 <br /> ESTIMATED QUANTITATION LIMITS FOR VOLATILE ANALYTESa <br /> Estimated Quantitation Limits <br /> 5-mL Ground Water 25-mL Ground water Low Soil/Sediment° <br /> Purge (pg/L) Purge (Ng/L) pg/kg <br /> 5 1 5 <br /> a Estimated Quantitation Limit (EQL) - The lowest concentration that can be reliably achieved <br /> within specified limits of precision and accuracy during routine laboratory operating conditions. <br /> The EQL is generally 5 to 10 times the MDL. However, it may be nominally chosen within <br /> these guidelines to simplify data reporting. For many analytes the EQL analyte concentration <br /> is selected for the lowest non-zero standard in the calibration curve. Sample EQLs are highly <br /> matrix-dependent. The EQLs listed herein are provided for guidance and may not always be <br /> achievable. See the following footnote for further guidance on matrix-dependent EQLs. <br /> EQLs listed for soil/sediment are based on wet weight. Normally data are reported on a dry <br /> weight basis, therefore, EQLs will be higher, based on the percent dry weight in each sample. <br /> Other Matrices Facto <br /> 1 <br /> Water miscible liquid waste 50 <br /> High concentration soil and sludge 125 <br /> Non-water miscible waste 500 <br /> EQL = [EQL for low soil sediment (Table 3)] x [Factor]. <br /> For non-aqueous samples, the factor is on a wet-weight basis. <br /> 8260B - 35 Revision 2 <br /> December 1996 <br />
