• A qua Ii ty con tro 1 analyte rec ove iy is outside of specified ac ce ptanc e criteria

• • Analyte is a Tracer compound

• • Analyte is a surrogate compound B The target anal yte was detected in the associated blank.

H Analytical holding time was exceeded J See case narrative for an explanation Value is estimated U Analyte was analyzed for, but not detected above the MDL, MDA, MDC or LOO .

Where the analytical method has be en performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the Certificate of Analysis.

The designation ND, if present, appears in the result column when the analyte concentration is not detected above the limit as de fined in the 'U' qualifier above.

This data report has been pre pi.red and reviewed in accordance with GEL Laboratories LLC standard operating procedures. Please direct any questions to yDur Project Manager, Hope Taylor.

Continuing Calibration Blanks (CCB) Requ irements Al l continuing calibration blanks(CCB) bracketing the sam ple in this SDG did not meet the acceptance criteria.

The samples bracketed by this CCB, however, containe d U 235 w ith a concentration at least ten tim es greater than the concentration in the B. This indicates that any contributi on to the concentration of U 235 in the samples from potential laboratory contarn ination would be minimal.

The MS&1SD (See Below) did not meet the recommended quality control acceptance criteria for percent recoveries for the follow ing applicable analytes.

The post spike recoveries were within lhe required control lim its. Th is verifies the absence or a matrix interforence in the post-spike digested sam ple. The recoveri es may be attributed to possible sample matrix interforcnce and/or non-homogeneity.

Ierboital In(ornrntjon Preparation/Analytica l 1ethod Verilication Method SW-846 30 OB is not a total diges tion technique for most samples. It is a very strong acid digestion that wi ll dissolve alm ost a ll elemenL5 that could become environmentally available. By design, elements bound in sili cate structures are not normally dissolved by this procedure as they are not usually mobile in the environment Sample Dilutions Dilutions may be required for many reasons, including to minim ize matrix interferences or to bring over range target analyte concentrations into the linear calibration range Samples were diluted to ensure that the analyte concentrations were within the linear calibration range of the instrument The ICPMS solid samples in this SDG were diluted the sumdard two tim es.

Technical Information Holding Time Specifications GEL assigns holding times based on the associated methodology. Holding time is measured by comparison of the date and time of sample collection to the date and tim e of sample preparation and ana lysis. Those holding limes expressed in hours are ca lculated in the AlphaLIMS system. Those holding Limes expressed as days expi re at mi dnight on the day of expiration. Samples (See Below) were not prepared and/or run within their required holding times due to laboratory error and/or instn.uuent fai lure.

The MS/MSD (See Below) did not meet the recommended quality control acceptance criteria for percent recoveries for the foll ow ing applicable analyte. The post spike recovery was within the required control lin1 its. This verifies the absence of a matrix interference in the post-spike digested sample. The recovery may be attributed to possible sample matrix interference and/or non-homogeneity.

Q One or more quality control criteria have not been met. Refer to the applicable narrative or DER.

R Per section 9.3.4.1 of Method 1664 Revision B, due to matrix spike recovery issues, this result may not be reported or used for regulatory compliance purposes.

" The Relative Percent Difference (RPD) obtained from Ute sample duplicate (DUP) is evaluated against Uie acceptance criteria when the sample is greater than five times (5 X) the contract required detection limit (RL). In cases where ei.Uter the sample or duplicate value is le Utan 5X the RL, a control Jim.it of +/- Ute RL is used to evaluate the DUP resttl t.

For PS, PSD, and SDT LT results, the va lues li sted are the measured amounts, not final concentration .

Where the analyti cal method has been performed under NELAP certification, th e ana lysis has met all of the requirements of the NELAC standard unless qualified on the QC Swn mary.

The samples bracketed by this CCB, however, contained U 235 with a concentration at least ten tim es greater than the concentration in the CB. This indicates that any contribution to the concentration of U 235 in the samples from potential laboratory contamination wo uld be min im al.

The MS/MSD (See Below) did not meet the recommended quality control acceptance criteria for percent recoveries for the follow ing applicable analytes.

The post spike recoveries were within the required control lim its. This verifies the absence of a matrix interference in the post-spike digested sample. The recoveries may be attributed to possible sample matrix interference and/or non-homogeneity.

Matrix Spike (MS)/Post Spike (PS) Recovery Statement The percent recoveries (%R) o btained from the spike analyses are evaluated when the sample concentration is less than four tim es ( 4)Q the spike concentration added . The matrix spike recovered outs ide of the established acceptance lin,iLs due to matrix interference and/or non-homogeneity.

( 1009 19-09) and 4926610 10 (100919-1 0) were diluted because target analyte concentrations exceeded the calibration mnge. Dilutions may be required for many reasons, including to minimize matrix interferences or to bring over range target analyte concentrations into the linear calibration range.
