ICP NARRATIVE PART 1

This part of the narrative covers the analysis of 18 soil samples from the named site sampled for ICPanalysis of total metals in soil.

For a listing of sample ID's, laboratory ID's, and sampling dates refer to the initial RLIMS reportpages where such a listing can be found.

The soil samples were received in good condition. The soils were dried at 105 °C overnight. The drysoils were ground using a laboratory ball mixer / grinder. Routine CRL hot block digestion procedures

WCRL SOP Metals 004 and Metals 025) were used to prepare the soil samples for GFAA and ICP^knalysis. The digested soil samples ( RLIMS Batch EK20404 ) were analyzed using the Optima

3300 DV ICP unit using analysis run method 'Sed 11132001 ESAT for the total metals analysis. Thesame digests were used for GFAA analyses, the results of which are reported separately.

ICP RUN RESULTS

Analyte mdl's determined during late summer of 2001 and rl values calculated from that informationfor ESAT analysis work for the Optima 3300 DV were used. The calculated rl values were used inreporting sample analysis results for this data case.

Because many samples contained high levels of zinc, a second analysis run was conducted wherediluted samples were run to determine and report Zn. All Zn sample results were reported from thisrun.

Presently no "contror actions are being implemented with the observed RL anatyte values actuallydetermined during the analysis run. RL check solution values currently are being analyzed forpurposes of generating a benchmark set of values which can be used to monitor the appropriatenessof any given RL level of analyte concentration.

Sample anaMe qualifications:

To date, compilation of control chart information is still on-going for some of the check audits fromOptima analysis runs for soils. Too little reliable data is currently available for some QA audits. Untilsuch time when compilation and evaluation of QA data is more complete, the default limits will beused.

Sample results for As, Sb, Se, and Tl were not reported by ICP; see GFAA results for these analyte

OOOOJ.O

Analysis RUN E2J2801 - Optima 3300 DV (continued) '

For Ba, all sample results are useable. The first Ba matrix spike audit concentration was at acomparable level as the samples and met QA audit control limits. This audit then is therefore anappropriate measure of matrix effects. Since the second Ba matrix spike audit concentration was at ahigher level than that for the samples it is a less appropriate measure of matrix effects on Ba, its lowrecovery should not significantly affect the Ba values for this data set.

For Fe, the ICP analyst contends that all Fe results are usable. The originally compiled control limitsfor the SRM were used rather than the later compilation which was used by the LIMS. The Fe SRMvalue met the original limits.

For Ag, the result for E2J2801-18 was flagged "L" and is estimated due to low bias indicated by theraw result being more negative than the negative value of the reporting limit for Ag. The Ag result forE2J2801-19 was flagged "J " since it had a result between the MDL and the rl value and is estimatedbecause of this.

Other comments

-afield QC samples included two pairs of field duplicates being designated: E2J2801-05 and -06, and%||2J2801-15 and -16. For the first pair Mn results did not exhibit good correlation. For the second

pair, results for Ba, Ca, Cu, Fe, Mg, Mn, Pb, and Zn did not exhibit good correlation.

* ICP NARRATIVE PART 2

This second part of the narrative covers the analysis of 7 soil sample TCLP extracts from the namedsite sampled for ICP analysis of selected analytes.

For a listing of sample ID's, laboratory ID's, and sampling dates refer to the initial RLIMS reportpages where such a listing can be found.

The samples were extracted using TCLP Method 1311 on 10-30-2002. An extraction blank wasincluded. Extraction fluid #1 was used for all seven samples and the blank. The extracts werepreserved for metals analysis by using nitric acid and lowering the pH to less than 2. The preservedextracts were prepared for ICP analysis on 11-4-2002 by using routine CRL hot block (water)digestion procedures. A tenfold dilution of the preserved extract solution was digested for theanalysis of each extract sample. The digested samples ( Prep batch EK20403 ) were analyzed on11-15-2002 using the Optima 3300 DV ICP unit using analysis run method water_080300_m_ESAT.Analyte holding times were met.

ICP RUN RESULTS

Analyte mdl's determined during late summer of 2001 and rl values calculated from that informationfor ESAT analysis work for the Optima 3300 DV were used. The calculated rl values were used inreporting sample analysis results for this data case.

3300 DV

The digested TCLP extracts (Prep Batch EK20403) were analyzed along with other sets of TCLPextracts. Copies of the raw analysis run printouts are included with this deliverable. A number of rawprintout pages did not print out well due to the printer ink supply running out during the middle of theanalysis run. Using the "Reprocessing" feature of the WinLab software the affected data were laterreprinted and are included with TCLP run pages of this deliverable at the end of the raw run dataprintouts.

Routine ESAT ICP reporting limits for the anatytes were used for reporting the extract analyte valuesfound rather than site specific action tevefe-as-limrts The extract analyte values reported reflect thetenfold dilution used to digest the extracts.

Sample analvte qualifications:

QA / QC summary reports are the traditional set based on "default" QA/ QC limits.

For As, the sample result for E2J2801-13 is flagged "J" since it had a result between the MDL andthe rl value and is estimated because of this.

Pb, the sample result for E2J2801-11 is flagged "J" since it had a result between the MDL andrl value and is estimated because of this.

For Se, the sample result for E2J2801-04 is flagged "J" since it had a result between the MDL andthe rl value and is estimated because of this. It is also flagged "K" due to possible high bias asindicated from the matrix spike audit result.
