NARRATIVE

One hundred three (103) soil samples from the US Smelter and Lead Refinery, Inc. site were collectedbetween April 26 and May 1, 2006 and were received properly preserved at CRL on April 28 and May 2,2006. The samples were submitted to ESAT for analysis of total metals including cadmium and lead by ICP.The sample point identifications are listed on the first page of the LIMS report following this narrative. Rawdata and QC forms are filed in the folder for E604004.

The soil samples were dried and ground between May 1 and 4,2006 prior to being digested followingstandard CRL 200.2 hot block digestion protocols (CRL SOP METALS025). They were batched in 5 LIMSbatches (LIMS digestion batch EE60204 thru EE60208). All batches were digested on May 4,2006. Theywere analyzed between May 8 and 17,2006 according to CRL SOP METALS004 using the Optima 4300.One batch (EE60205) was reanalyzed due to instrument QC problems in the run. Recently completed (notlisted in METALS004) U.S. EPA MDL/RL values were used for evaluation of the data per Dr. J. V. Morris.ESAT has not had an opportunity to perform MDL/RL evaluations.

The following analytes will be addressed in this case narrative:

Al, Ba, Be, Ca, Cd, Cr, Co, Cu, Fe, Mg, Mn, Ni, Pb, K, Ag, Na, V, Zn

Qualifications of results will be limited to samples within each individual digestion batch. Each was analyzedas a separate analytical run. The following lists the case pertinent out-of-control QC audit check results:

Batches: EE60204 contains samples E604004-03 thru -22 (run May 8,2006)EE60205 contains samples E604004-23 thru -42 (run May 17,2006)EE60206 contains samples E604004-43 thru -62 (run May 11, 2006)EE60207 contains samples E604004-63 thru -68 and E605001-04 thru -17 (run May 12,2006)EE60208 contains samples E605001-18 thru -40 (run May 15,2006)

RL Check Soln: Presently no "control" actions are associated with the observed RL analyte valuesactually determined during the analysis run. RL check solution values currently arebeing analyzed for purposes of generating a benchmark set of values which can be usedto monitor the appropriateness of any given RL level of analyte concentration. Valuesare subject to change pending further repairs on the instrument. Since no soil RLsolution has been prepared, CRL and ESAT water (METALS003) RL solutions wereanalyzed in the analytical run.

Sample element qualifications:

Control limits are normally set according to ESAT control charts. However, not enough data points forinstrument checks have been analyzed to determine ESAT control limits. Those control limits are setaccording to EPA limits. ESAT control limits are used for matrix QC. A linearity check sample wasperformed for Ba, Cr, Cu, Mn, Ni, Pb and Zn to extend the usable range of the instrument.

For Ag, negative Ag values whose absolute values were greater than the MDL were present for the digestionblank EE60205-BLK1 indicating a possible low bias. Samples E604004-25 thru -27, -29 thru -31 and -35 areflagged "L" in LIMS indicating the possible low bias. The instrument value for non-detect samples E604004-24 and -28 were sufficiently high to be affected by the possible low bias; those samples are also flagged "L"in LIMS. In the same analytical run, Ag results for the control samples EE60205-SRM1 and EE60208-SRM1were less than the lower ESAT limit indicating a possible low bias; Ag results for samples E604004-23 thru -42, E605001-18 thru -40 and control samples EE60205-SRM1 and EE60208-SRM1 are flagged "L" in LIMSdue to possible low bias.

Other commentsSamples E604004-30/-31, -44/-4S, -52/-S3, E605001-09/-10 and -39/-40 were identified as field duplicates.E604004-30/-31 showed good correlation for all elements except Pb, E604004-44/-45 showed goodcorrelation for all elements except Ag, E604004-52/-53 showed good correlation for all elements except Ni,E605001-09/-10 showed good correlation for all elements except Ca and Mg and E605001-39/40 showedgood correlation for all elements except Cu, Na and Ni. Determinations of correlation were made accordingto laboratory duplicate criteria; however, no sample results are qualified for field duplicates.

It has been observed that, due to differences in the significant figures used for calculation, RPD values andsome matrix spike recoveries calculated by LIMS are not correct. Some of these values are reported by LIMSas being outside QC requirements when they are not. The correct values are included as Excel spreadsheets inthe Analytical/Matrix QC Summary Report provided in the data package.

NARRATIVE

Five (5) water samples from the US Smelter and Lead Refinery, Inc. site were collected between April 26 andMay 1,2006 and were received properly preserved at CRL on April 28 and May 2,2006. The samples weresubmitted to ESAT for analysis of total metals by ICP. The sample point identifications are listed on the firstpage of the LIMS report following this narrative.

The water samples were digested following standard CRL 200.2 hot block digestion protocols (CRL SOPMETALS025) on May 3, 2006 (LIMS digestion batch EE60203). The samples were analyzed on May 5, 2006according to CRL SOP METALS003 using the Optima 4300. Recently reevaluated (not listed inMETALS003) U.S. EPA MDL/RL values were used for evaluation of the data per Dr. J. V. Morris becausechanges were made to the instrument and ESAT has not had an opportunity to perform new MDL/RLevaluations.

The following analytes will be addressed in this case narrative:

Sb, Al, As, Ba, Be, Ca, Cd, Cr, Co, Cu, Fe, Pb, Mg, Mn, Ni, K, Se, Ag, Na, Tl, V, Zn

The following lists the case pertinent out-of-control QC audit check results based on ESAT QA/QC limits:

RL Check Soln: Presently no "control" actions are associated with the observed RL analyte valuesactually determined during the analysis run. RL check solution values currently arebeing analyzed for purposes of generating a benchmark set of values which can be usedto monitor the appropriateness of any given RL level of analyte concentration. Valuesare subject to change pending further repairs on the instrument. U.S. EPA and ESATRL solutions were analyzed in the April 25, 2006 analytical run.

<5X: Sample and/or duplicate <5X MDL; duplicate difference acceptable (<MDL).*: Indicates out of control result (ESAT limits)

2 of 3Note: Although the duplicate difference is greater than the MDL for Be313, Cd226, Cu327 and Sb206, bothsample and duplicate values are less than the MDL and the difference is considered acceptable.

Sample element qualifications:

Control limits are normally set according to ESAT control charts. However, not enough data points forinstrument checks have been analyzed to determine ESAT control limits. Those control limits are setaccording to EPA limits. ESAT control limits are used for matrix QC.

For Ba, the sample and laboratory duplicate were less than 5X the MDL; duplicate difference is used for thecontrol criteria. The matrix duplicate difference is greater than the MDL indicating possible poor precision; allBa sample results and EE60203-DUP1 are flagged "*" in LIMS due to possible poor precision. Also, thesample results for E604004-01 and E605001-01 are greater than the MDL but less than the RL; Ba for thosesamples are flagged "J" in LIMS.

For Ca, the sample results for E604004-02, E605001-02 and -03 are greater than the MDL but less than theRL; Ca for those samples are flagged "J" in LIMS.

For Co, one of the instrument blanks had a value greater than the MDL indicating possible contamination.Sample results for E604004-02 and E605001-01 are flagged "K" in LIMS due to the possible contamination.Additionally, sample results for E604004-02 and E605001-01 are greater than the MDL but less than the RL;Co for those samples are also flagged "J" in LIMS.

For Cr, the sample result for E605001-02 is greater than the MDL but less than the RL; Cr for that sample isflagged "J" in LIMS.

For Cu, the sample results for E605001-01 thru -03 are greater than the MDL but less than the RL; Cu forthose samples are flagged "J" in LIMS.

For Fe, all Fe results were reported from the Fe 259 line. The sample results for E604004-02 and E605001-01are greater than the MDL but less than the RL; Fe for those samples are flagged "J" in LIMS.

For Mg, all results are reported from the Mg 280 line.

For Mn, the sample results for E604004-01 and E605001-02 are greater than the MDL but less than the RL;Mn for those samples are flagged "J" in LIMS.

For Na, the duplicate RPD was greater than the ESAT limit indicating possible poor precision; all Na sampleresults and EE60203-DUP1 are flagged "*" in LIMS due to possible poor precision.

For Se, the sample result for E604004-02 is greater than the MDL but less than the RL; Se for that sample isflagged "J" in LIMS.

For V, both of the instrument blanks had values greater than the MDL indicating possible contamination. Thesample results for E604004-02, E605001-01, and -02 are flagged "K" in LIMS due to the possiblecontamination. Also, the sample was less than the MDL and laboratory duplicate were less than 5X the MDL;duplicate difference is used for the control criteria.

Finally, the sample results for E604004-02, E605001-01, and -02 are greater thanthe MDL but less than the RL; V for those samples are also flagged "J" in LIMS.

For Zn, the laboratory duplicate was less than 5X the MDL; duplicate difference is used for the controlcriteria. The matrix duplicate difference is greater than the MDL indicating possible poor precision; all Znsample results and EE60203-DUP1 are flagged "*" in LIMS due to possible poor precision. Also, all sampleresults are greater than the MDL but less than the RL; all Zn sample results are flagged "J" in LIMS.

All flagged results except those flagged "<5X" are considered estimated.

Other comments

No samples were identified as field duplicates or field blanks.

It has been observed that, due to differences in the significant figures used for calculation, RPD values andsome matrix spike recoveries calculated by LIMS are not correct. The correct values are included as Excelspreadsheets in the Analytical/Matrix QC Summary Report provided in the data package.

NARRATIVE

One hundred three (103) soil samples from the US Smelter and Lead Refinery, Inc. site were collectedbetween April 26 and May 1, 2006 and were received properly preserved at CRL on April 28 and May 2,2006. The samples were submitted to ESAT for analysis of antimony, arsenic, selenium, and thallium byGFAA. The sample point identifications are on the first pages of the LIMS report following this narrative.Raw data and QC forms are filed in the folder for E604004.

The soil samples were dried and ground between May 1 and 4, 2006 prior to being digested followingstandard CRL 200.2 hot block digestion protocols (CRL SOP METALS025). They were batched in 5LIMS batches (LIMS digestion batches EE60204 containing samples E604004-03 thru -22, EE60205containing samples E604004-23 thru -42, EE60206 containing samples E604004-43 thru -62, EE60207containing samples E604004-63 thru -68 and E605001-04 thru -17 and EE60208 containing samplesE605001-18 thru -40). All batches were digested on May 4,2006. They were analyzed between May 5 and22, 2006 using 200.9 methods (CRL SOP's MET ALSO 17/019). Antimony and thallium were analyzed onthe SimAA 6000 using the single element programs (CRL SOP MET ALSO 17). Arsenic and selenium wereanalyzed on the AAnalyst 800 (CRL SOP METALS019). QC limits are based on ESAT control limits; CRLdefault limits are used if ESAT limits are greater than CRL limits.

Because reported QC values are less than 5 times the MDL for all selenium and thallium samples, duplicatedifference criteria are used for control purposes for all selenium and thallium QC samples; all selenium andthallium matrix duplicates (EE60204-DUP1, -DUP2, EE60205-DUP1, -DUP2, EE60206-DUP1, -DUP2,EE60207-DUP1, -DUP2, EE60208-DUP1, -DUP2, -DUP3) are flagged "<5X" in LIMS. Duplicate RPDwas used for control purposes for antimony and arsenic. Antimony duplicates EE60207-DUP2 andEE60208-DUP1 and arsenic duplicate EE60206-DUP2 did not meet QC requirements indicating possiblepoor precision. No redigestion/reanalysis were performed due to time constraints. Antimony for samplesE604004-63 thru -68 and E605001-04 thru -40 and duplicates EE60207-DUP2 and EE60208-DUP1 andarsenic for samples E604004-43 thru -62 and duplicate EE60206-DUP2 are flagged "*" in LIMS andconsidered estimated. All other QC values were within limits. All samples were analyzed within theholding time limit.

The following results between the method detection limit (MDL) and the RL are reported as the instrumentvalue with a "J" flag and are considered estimated: E604004-03, -05, -07, -08, -10, -12 thru -17, -21 thru -23,-26, -30, -32, -33, -36 thru -39, -41, -42, -44 thru -48, -50 thru -53, -64, -67, E605001-06, -09, -11, -14, -15, -17thru -25, -27, -29, -31 thru -33, -37, -39 and -40 for selenium; E604004-03 thru -05, -30, -31, -39, -44, -53,E605001-29, -34, -38 and -40 for thallium. The following reported values are adjusted for dilution: allantimony results except digestion blanks and E604004-59 and E605001-19 thru -24; all arsenic results exceptdigestion blanks; all control samples, blank spikes and matrix spikes plus samples E604004-06, -08, -13, -15,-53, E605001-25, -33 and -37 for selenium; all thallium samples except digestion blanks. All other sampleresults are acceptable. Where appropriate, reported values are dilution corrected.

Samples E604004-30/-31, -44/-4S, -527-53, E605001-09/-10 and -39/-40 were identified as field duplicates.All show good correlation for all elements except E604004-52/-53 arsenic and selenium. Determinations ./.

"- s~*

of correlation were made using laboratory duplicate criteria. No sample results are qualified for fieldduplicates. No samples were identified as field blanks.

QC reports which include analytical QC are provided as Excel spreadsheets. Logbook entries for thismetals analysis can be found in an ESAT Laboratory Notebook. It has been observed that, due todifferences in the significant figures used for calculation and rounding of reported values, RPD values andsome matrix spike recoveries calculated by LIMS are not correct. The correct values are included in theExcel spreadsheets in the Analytical/Matrix QC Summary Report provided in the data package.

NARRATIVE

Five (5) water samples from the US Smelter and Lead Refinery, Inc. site were collected between April 26 andMay 1,2006 and were received properly preserved at CRL on April 28 and May 2,2006. The samples weresubmitted to ESAT for analysis of total metals by ICP. The sample point identifications are listed on the firstpage of the LIMS report following this narrative.

The water samples were digested following standard CRL 200.2 hot block digestion protocols (CRL SOPMETALS025) on May 3,2006 (LIMS digestion batch EE60203). The samples were analyzed on May 5,2006according to CRL SOP METALS003 using the Optima 4300. Recently Devaluated (not listed inMETALS003) U.S. EPA MDL/RL values were used for evaluation of the data per Dr. J. V. Morris becausechanges were made to the instrument and ESAT has not had an opportunity to perform new MDL/RLevaluations.

The following analytes will be addressed in this case narrative:

Sb, Al, As, Ba, Be, Ca, Cd, Cr, Co, Cu, Fe, Pb, Mg, Mn, Ni, K, Se, Ag, Na, Tl, V, Zn

The following lists the case pertinent out-of-control QC audit check results based on ESAT QA/QC limits:

Blanks: Instr. Blank 1 Co 228 0.36 ug/LNi231 0.71 ug/LV 292 0.60 ug/L

Instr. Blank 2 Ni 231 0.54 ug/LV 292 0.69 ug/L

RL Check Soln: Presently no "control" actions are associated with the observed RL analyte valuesactually determined during the analysis run. RL check solution values currently arebeing analyzed for purposes of generating a benchmark set of values which can be usedto monitor the appropriateness of any given RL level of analyte concentration. Valuesare subject to change pending further repairs on the instrument. U.S. EPA and ESATRL solutions were analyzed in the April 25,2006 analytical run.

<5X: Sample and/or duplicate <5X MDL; duplicate difference acceptable (<MDL).*: Indicates out of control result (ESAT limits)

2 of 3Note: Although the duplicate difference is greater than the MDL for Be313, Cd226, Cu327 and Sb206, bothsample and duplicate values are less than the MDL and the difference is considered acceptable.

Sample element qualifications:

Control limits are normally set according to ESAT control charts. However, not enough data points forinstrument checks have been analyzed to determine ESAT control limits. Those control limits are setaccording to EPA limits. ESAT control limits are used for matrix QC.

For Ba, the sample and laboratory duplicate were less than 5X the MDL; duplicate difference is used for thecontrol criteria. The matrix duplicate difference is greater than the MDL indicating possible poor precision; allBa sample results and EE60203-DUP1 are flagged "*" in LIMS due to possible poor precision. Also, thesample results for E604004-01 and E605001-01 are greater than the MDL but less than the RL; Ba for thosesamples are flagged "J" in LIMS.

For Ca, the sample results for E604004-02, E605001-02 and -03 are greater than the MDL but less than theRL; Ca for those samples are flagged "J" in LIMS.

For Co, one of the instrument blanks had a value greater than the MDL indicating possible contamination.Sample results for E604004-02 and E605001-01 are flagged "K" in LIMS due to the possible contamination.Additionally, sample results for E604004-02 and E605001-01 are greater than the MDL but less than the RL;Co for those samples are also flagged "J" in LIMS.

For Cr, the sample result for E605001-02 is greater than the MDL but less than the RL; Cr for that sample isflagged "J" in LIMS.

For Cu, the sample results for E605001-01 thru -03 are greater than the MDL but less than the RL; Cu forthose samples are flagged "J" in LIMS.

For Fe, all Fe results were reported from the Fe 259 line. The sample results for E604004-02 and E605001-01are greater than the MDL but less than the RL; Fe for those samples are flagged "J" in LIMS.

For Mg, all results are reported from the Mg 280 line.

For Mn, the sample results for E604004-01 and E605001-02 are greater than the MDL but less than the RL;Mn for those samples are flagged "J" in LIMS.

For Na, the duplicate RPD was greater than the ESAT limit indicating possible poor precision; all Na sampleresults and EE60203-DUP1 are flagged "*" in LIMS due to possible poor precision.

For Se, the sample result for E604004-02 is greater than the MDL but less than the RL; Se for that sample isflagged "J" in LIMS.

For V, both of the instrument blanks had values greater than the MDL indicating possible contamination. Thesample results for E604004-02, E605001-01, and -02 are flagged "K" in LIMS due to the possiblecontamination. Also, the sample was less than the MDL and laboratory duplicate were less than 5X the MDL;duplicate difference is used for the control criteria. The matrix duplicate difference is greater than the MDL

3 of 3indicating possible poor precision; all V sample results and EB60101-DUP1 are also flagged "*" in LIMS dueto possible poor precision. Finally, the sample results for E604004-02, E605001-01, and -02 are greater thanthe MDL but less than the RL; V for those samples are also flagged "J" in LIMS.

For Zn, the laboratory duplicate was less than 5X the MDL; duplicate difference is used for the controlcriteria. The matrix duplicate difference is greater than the MDL indicating possible poor precision; all Znsample results and EE60203-DUP1 are flagged "*" in LIMS due to possible poor precision. Also, all sampleresults are greater than the MDL but less than the RL; all Zn sample results are flagged "J" in LIMS.

All flagged results except those flagged "<5X" are considered estimated.

Other comments

No samples were identified as field duplicates or field blanks.

It has been observed that, due to differences in the significant figures used for calculation, RPD values andsome matrix spike recoveries calculated by LIMS are not correct. The correct values are included as Excelspreadsheets in the Analytical/Matrix QC Summary Report provided in the data package.

TDF: R5-01-004,5TechLaw Job #: 03037.1.01.02.01.053J.000.004,5Task Order #: R5-0-01Data Sets: E604004, E605001

NARRATIVE

One hundred three (103) soil samples from the US Smelter and Lead Refinery, Inc. site were collectedbetween April 26 and May 1, 2006 and were received properly preserved at CRL on April 28 and May 2,2006. The samples were submitted to ESAT for analysis of total metals including cadmium and lead by ICP.The sample point identifications are listed on the first page of the LIMS report following this narrative. Rawdata and QC forms are filed in the folder for E604004.

The soil samples were dried and ground between May 1 and 4,2006 prior to being digested followingstandard CRL 200.2 hot block digestion protocols (CRL SOP METALS025). They were batched in 5 LIMSbatches (LIMS digestion batch EE60204 thru EE60208). All batches were digested on May 4,2006. Theywere analyzed between May 8 and 17, 2006 according to CRL SOP METALS004 using the Optima 4300.One batch (EE60205) was reanalyzed due to instrument QC problems in the run. Recently completed (notlisted in METALS004) U.S. EPA MDL/RL values were used for evaluation of the data per Dr. J. V. Morris.ESAT has not had an opportunity to perform MDL/RL evaluations.

The following analytes will be addressed in this case narrative:

Al, Ba, Be, Ca, Cd, Cr, Co, Cu, Fe, Mg, Mn, Ni, Pb, K, Ag, Na, V, Zn

Qualifications of results will be limited to samples within each individual digestion batch. Each was analyzedas a separate analytical run. The following lists the case pertinent out-of-control QC audit check results:

Batches: EE60204 contains samples E604004-03 thru -22 (run May 8, 2006)EE60205 contains samples E604004-23 thru -42 (run May 17, 2006)EE60206 contains samples E604004-43 thru -62 (run May 11, 2006)EE60207 contains samples E604004-63 thru -68 and E605001-04 thru -17 (run May 12, 2006)EE60208 contains samples E605001-18 thru -40 (run May 15, 2006)

RL Check Soln: Presently no "control" actions are associated with the observed RL analyte valuesactually determined during the analysis run. RL check solution values currently arebeing analyzed for purposes of generating a benchmark set of values which can be usedto monitor the appropriateness of any given RL level of analyte concentration. Valuesare subject to change pending further repairs on the instrument. Since no soil RLsolution has been prepared, CRL and ESAT water (METALS003) RL solutions wereanalyzed in the analytical run.

Control limits are normally set according to ESAT control charts. However, not enough data points forinstrument checks have been analyzed to determine ESAT control limits. Those control limits are setaccording to EPA limits. ESAT control limits are used for matrix QC. A linearity check sample wasperformed for Ba, Cr, Cu, Mn, Ni, Pb and Zn to extend the usable range of the instrument.

For Ag, negative Ag values whose absolute values were greater than the MDL were present for the digestionblank EE60205-BLK1 indicating a possible low bias. Samples E604004-25 thru -27, -29 thru -31 and -35 areflagged "L" in LIMS indicating the possible low bias. The instrument value for non-detect samples E604004-24 and -28 were sufficiently high to be affected by the possible low bias; those samples are also flagged "L"in LIMS. In the same analytical run, Ag results for the control samples EE60205-SRM1 and EE60208-SRM1were less than the lower ESAT limit indicating a possible low bias; Ag results for samples E604004-23 thru -42, E605001-18 thru -40 and control samples EE60205-SRM1 and EE60208-SRM1 are flagged "L" in LIMSdue to possible low bias.

Other commentsSamples E604004-30/-31, -44/-4S, -527-53, E605001-09/-10 and -39/-40 were identified as field duplicates.E604004-30/-31 showed good correlation for all elements except Pb, E604004-44/-45 showed goodcorrelation for all elements except Ag, E604004-52/-53 showed good correlation for all elements except Ni,E605001-09/-10 showed good correlation for all elements except Ca and Mg and E605001-39/40 showedgood correlation for all elements except Cu, Na and Ni. Determinations of correlation were made accordingto laboratory duplicate criteria; however, no sample results are qualified for field duplicates.

It has been observed that, due to differences in the significant figures used for calculation, RPD values andsome matrix spike recoveries calculated by LIMS are not correct. Some of these values are reported by LIMSas being outside QC requirements when they are not. The correct values are included as Excel spreadsheets inthe Analytical/Matrix QC Summary Report provided in the data package.
