1.0 Introduction

The U.S. Environmental Protection Agency (USEPA) is currently conductingremedial design (RD) activities at the Mid-America Tanning (MAT) Site nearSergeant Bluff, Iowa. Black & Veatch Special Projects Corp. (BVSPC) has beensubcontracted by the USEPA under the Remedial Action Contracts (RACs) programto provide RD services. As part of the work efforts, BVSPC conducted asupplemental investigation (SI) for the site. The Supplemental Investigation wasfollowed by Verification Sampling to confirm the results from the SupplementalInvestigation. The Verification Sampling was done in support of the SupplementalInvestigation performed in December 1997.

1.1 ObjectivesThis Verification Sampling Addendum provides data collected during verification

sampling efforts. Verification sampling efforts included the collection of surfacewater samples necessary to fill data gaps for the remedial design. Data Validationand PARCC Reports for the data were prepared by Heartland EnvironmentalServices, Inc., St. Charles, Missouri and are included as part of this addendum asAppendix ADD-A and Appendix ADD-B, respectively. Verification samplingactivities were performed on March 23, 1998 through March 25, 1998.

1.2 Site ActivitiesVerification sampling efforts included the collection of surface water samples to

fill data gaps for the remedial design. Sampling and analysis was performed asdescribed in the Quality Assurance Project Plan, Mid-America Tanning Site, RevisedNovember 7, 1997. Details for the sampling efforts are provided in the field logbookswhich are included for reference (Appendix ADD-C). Modifications to the samplingefforts included the deletion of Cr (VI), TSS, and ammonia/nitrogen analyses fromall surface impoundments and the deletion of total Cr from all impoundments exceptthe East and West Aeration Lagoons. Other revisions included the addition offiltered analyses for BOD, COD, and total Cr.

The following samples were collected from the East Lagoon:• EL-SW-1-P.• EL-SW-2-P.

1.3 Validation and Evaluation of DataAs part of the work efforts, a validation and evaluation of the data were

performed by Heartland Environmental Services, Inc., St. Charles, Missouri undersubcontract to Black & Veatch Special Projects Corp. (BVSPC). The reportsevaluated 23 samples including quality assurance and quality control samples as partof the validation and evaluation process. Prior to data evaluation, the raw laboratorydata were validated using the Laboratory Data Validation Functional Guidelines forEvaluating Inorganic Analyses (EPA 1994). The validation procedure and results arepresented in the Data Validation Report, Mid-America Tanning Site, June 15, 1998(Appendix ADD-A). The data were then evaluated for the following criteria:precision, accuracy, representativeness, comparability, and completeness (PARCC)in reference to the Data Quality Objectives (DQOs) of the site specific quality


assurance project plan (BVSPC November 7, 1997). The evaluation procedure andresults are presented in the PARCC report for the verification sampling data June1998 (Appendix ADD-B).

Results of the data validation and PARCC review process have determined thedata are defensible, were collected in accordance with the site specific QAPP andFSP, and are useable for the intended purposes.

1.4 Data ResultsResults of the verification sampling are presented in Table ADD-1. Verification

sampling confirmed that chromium levels were less than sampling events prior toBVSPC's testing, which supports redesign efforts to eliminate chromium treatment.Verification sampling verified that BOD levels in the first sampling event were notrepresentative of the site. The sampling results now indicate BOD/COD ratios thatare consistent with normally occurring ratios. The BOD levels justify retainage of theoriginal design.

Prior to evaluating the data for precision, accuracy, representativeness, comparability, and completeness (PARCC)criteria the laboratory reviewed the data package. Before the laboratory released the chemical analytical results, boththe sample and laboratory QC data were carefully reviewed in order to verify sample identity, instrument calibration,detection limits, dilution factors, numerical computations, accuracy of transcriptions, and chemical interpretations.The data were compiled into Black & Veatch Level IV data packages and any nonconfonning data were discussed inthe data package cover letter and case narrative.

The Level IV data packages were dien reviewed and validated by Heartland Environmental Services, Inc., Missouri(Heartland). Data validation is the technical review of a data package using criteria established in the data qualityobjectives, the site specific quality assurance project plan (QAPP)(BVSPC 1997), and guidance documents preparedby the United States Environmental Protection Agency (USEPA) for the validation of organic and inorganic analyticaldata (USEPA 1994a and 1994).

Samples that did not meet the acceptance limit criteria were qualified with a Sag; single letter abbreviations chatindicate a problem with the data. Data qualifiers used by the validators when amending the data include the following.

H Undetected. The analyte was not detected above the contract required quantitation limit (CRQL)or the contract required detection limit (CRDL). The "U" designator also is used to qualifycommon laboratory contaminants. The "U" designator is applied to an environmental sample whenthe laboratory contaminant is detected in an environmental sample at a concentration less than 5times (10 times for common laboratory contaminants) the value of the concentration detected in anycorresponding field QC blank, method blank or preparation blanks.

i Estimated. The analyte was present, but the reported value may not be accurate or precise. The"J" designator is used to qualify an analyte that was present at a concentration between theCRQL/CRDL and method detection limit (MDL) or die data "failed" some of the analyticalvalidation criteria but not sufficient to reject the data and when combined with the U designator thequantitation limit is estimated.

£ Rejected. Data was rejected by die data validator during comparison of die DQO Level III datapackage with the analytical functional guideline criteria. The "R" designator indicates a significantvariance in acceptable laboratory performance. Either re-analysis or re-sampling and analysis wouldbe necessary to determine the presence or absence of the target compound(s)/analyte(s).

Once the data were reviewed and validated, die data were evaluated by Heartland using die PARCCs criteria includedin the Quality Assurance Project Plan for die Mid America Tannery Site, Sioux City, Iowa. The following sectionspresent a brief description of PARCCs criteria.

Precision. Precision is a measure of die agreement or repeatability of a set of replicate results obtained from duplicatelaboratory analyses of samples collected from die same location/depth interval. Precision was calculated fromlaboratory analytical data and cannot be measured directly. Precision is expressed as die Relative Percent Difference(RPD) between analytical values for two samples divided by die average of their analytical values. Precision iscalculated using die expression:

RPD - (D1-D2) / (K(D1+D2)) x 100

D 1 and D2 are die reported values for die duplicate sample pair. Precision was evaluated using field duplicate samplesand laboratory split samples (for example, MS/MSD samples).

1-1

Precision for environmental samples and their duplicates was assessed using a maximum RPD of 20 percent for thewater matrix. Precision for MS/MSD/MD samples was assessed by using the target compound/analyte specific RPDcriteria for die spiked compounds/analytes and the sample duplicates.

Accuracy. Accuracy is a measure of the agreement between an experimental determination and the true value of theparameter being measured. Accuracy can be calculated from the analytical data and was not measured directly.Accuracy is used to identify the bias in a given measurement system (i.e. laboratory conditions, sample matrix, andsampling conditions). Accuracy is assessed by reviewing the Percent Recovery (%R) between the true value of thespike compound/analyte and the actual analytical value. Accuracy is calculated using the equation:

%R = ((A-B)/C) x 100A = Measured concentration of the spiked analyte.B = Measured concentration of the spiked compound in the unspiked sample.C - True concentration of the spiked analyte.

For the inorganic analyses, each chosen matrix spike and matrix spike duplicate pair was spiked with a knownreference material before digestion. This approach provides a measure of the matrix effects on die analytical accuracy.

Representativeness. Representativeness is a qualitative measure of the degree to which sample data accurately andprecisely represent a characteristic environmental condition. Representativeness is a subjective parameter and is usedto evaluate the efficacy of the sampling plan design. Representativeness was evaluated using the field and laboratoryQC blank sample results. QC blank samples are equipment rinseate blanks, field blanks, trip blanks, laboratorymethod blanks for organic analysis and laboratory preparation blanks for inorganic analysis. Positive detection oftarget compounds/analytes in die QC blank samples identify contaminants dm possibly were introduced to theassociated environmental sample during sample collection, transport or laboratory analysis. Representativeness wasalso evaluated using die defined extraction and analytical holding time requirements set forth in die Quality AssuranceProject Plan for die Mid America Tannery Site, Sioux City, Iowa and/or die analytical mernodology.

Comparability. Comparability is qualitative measure designed to express die confidence witii which one data set maybe compared to anodier. Factors that affect comparability are: sample collection and handling techniques, samplematrix type, and analytical mernod. Comparability is limited by die odier PARCC parameters because only whenprecision and accuracy are known can data sets be compared wirn confidence.

Completeness. Completeness is defined as die percentage of measurements diat are judged to be valid compared todie total number of measurements made. Valid usable data are values that were not qualified as rejected (R) qualifierduring data validation. A goal of 90 percent usable data was established in die Quality Assurance Project Plan fordie Mid America Tannery Site. Sioux City, Iowa. Completeness equals die total number of analytes for each matrixminus die total number of rejected analytes divided by die total number of analytes multiplied by 100.

2.0 PRECISION

The following section describes die evaluation of precision for die analytical methods submitted in diis sampling eventfor which precision data was available. Duplicate samples are evaluated for precision only when contaminants aredetected in both die environmental sample and the sample's duplicate. A ND in die RPD column of die spreadsheetindicates that a RPD calculation was not required because one result was a non-detect and die odier result was lessthan die compound/analyte CRQL/CRDL. Environmental samples and their respective duplicates may not exhibitpositive results for all compounds found at or near the CRQL or CRDL. Duplicates witii Relative Percent Differences(RPDs) within control limits indicate adequate sampling practices and/or good analytical precision. Duplicates withRPDs outside die control limits may result from inappropriate sampling procedures, matrix interferences, or non-homogeneity of die sample matrix. In addition, poor precision can be attributed to deviation(s) from die analyticalmediodology or to poor reproducibility of target analyte concentrations at or near die required CRQLs or CRDLs.The acceptance criteria for evaluating precision of field duplicate analytical results is a RPD of 20 for die watermatrix.

Field duplicates were submitted for validation for all analytical fractions. The percentage of duplicate samplescollected for this project was greater than five percent for all fractions. Based on die document Guidance for DataUsability in Risk Assessment, EPA 540 G-90 008, October 1990, a minimum of 5 % field duplicates is recommendedto examine die measurement error due to sampling.

The following Sections summarize die evaluation of analytical precision for die soil & water field samples for diefollowing analytical groups:

• Metals Analytes (Chromium)• Wet Chemistry Parameters (BOD, COD, Oil & Grease, & TSS

Duplicate precision was assessed using both environmental sample and associated duplicates and matrix spike/matrixspike duplicates/matrix duplicates (MS/MSD/MDs).

Tabulation of die results of assessing duplicate precision and duplicate frequency are presented in Tables 2-1 through2-5 for die water matrix. Tabulation of die results ?s$es$i"g precision based on die reproducibility between spikesample/duplicate sample pairs are presented in Table 2-6 for die water matrix.

To assess die potential for non-compliance in die chromium analytical data, caused by physical and/or chemicalinterferences and infftpatpH by non-compliant serial dilution results, tables would be prepared of serial dilution results.These would be included in Appendix B. Serial dilution results were not submitted for chromium. Therefore, therewere no tables required for Appendix B.

2.1 Water Matrix

The assessment of water matrix environmental samples and associated duplicates for precision are provided in Tables2-1 dirough 2-5.

The field duplicate pair of sample EL-SW-6-P analyzed for die chromium fraction exhibited non-compliant RPDs forboth die unfiltered and filtered analyses (Table 2-1, page 2-2). In die unfiltered chromium analysis the analyte wasreported in the field sample at a higher concentration dian in die field duplicate. The non-compliance may beattributed field and/or laboratory inconsistencies. The non-compliance was slight (23 %) for die filtered chromiumanalysis of die field duplicate pair. The non-compliance may be attributed to laboratory inconsistencies.

All RPD criteria was met for die filtered BOD analysis of die field duplicate pair of sample EL-SW-6-P (Table 2-2,page 2-3). The unfiltered analysis for BOD of die field duplicate pair of sample EL-SW-6-P exhibited a non-

The field duplicate pair of sample EL-SW-6-P analyzed for die COD fraction exhibited a non-compliant RPD for theunfiltered analysis of dbe sample (Table 2-3, page 2-4). The non-compliance was slight (21 %) and may be attributedto laboratory inconsistencies. All RPD criteria was met for die filtered COD analysis of die field duplicate pair ofsample EL-SW-6-P (Table 2-3, page 2-4).

The field duplicate pair of sample EL-SW-6-P analyzed for Oil and Grease exhibited a non-compliant RPD (Table2-4, page 2-5). The non-compliance was slight (25%) and may be attributed to laboratory and/or field inconsistencies.

The field duplicate pair of sample EL-SW-6-P analyzed for TSS (Total Suspended Solids) exhibited a non-compliantRPD (Table 2-5, page 2-6). The non-compliance may be attributed to laboratory and/or field inconsistencies.

The assessment of precision based on die reproducibility of results between matrix spike and matrix spike duplicate(metals fraction) pairs is provided in Table 2-6.

The MS/MSD sample pair analyzed for die chromium and filtered chromium fractions for die water matrix were "incompliance" wirn RPD precision requirements (Table 2-6). The matrix duplicate pair analyzed for die chromiumfraction exhibited a non-compliant RPD of 23.5% (Table 2-6). Therefore, me positive chromium results, reportedin all of die samples were appropriately qualified as estimated, J.

Based on assessment of duplicate precision evaluation criteria, die water sample matrix analytical data was acceptablefor precision for die SDG for all fractions with die exception of die unfiltered chromium fraction. Eleven (11)positive chromium results were qualified as estimated. J. All results qualified as estimated, J, are considered usable.

2-8

3.0 ACCURACY

The assessment of accuracy is evaluated by comparison of the percent recoveries (%R) computed from the knownconcentration of analyte spikes and their recovered concentration versus the analytical method acceptance criteria.Spike recoveries provide an indication of bias, where the reported data may either overestimate or underestimate dieactual concentration of detected compounds and/or the detection limits. Recoveries outside acceptable criteria maybe caused by factors such as matrix interference, poor analytical precision, or instrument calibration.

The following Sections summarize die evaluation of analytical accuracy for the field soil and water samples for thefollowing analytical groups:

• Metals Analyte (Chromium)

Accuracy was assessed using MS and MSD samples for die chromium analyses. There were no MS/MSD pairsanalyzed for the wet chemistry fractions. The results of the evaluation of accuracy for die MS/MSD samples isprovided in Table 2-6 for die water matrix.

3.1 Water Matrix

The results of die evaluation of accuracy for die MS/MSD samples are provided in Tables 2-6 for die water matrix.

The MS/MSD pair analyzed for die chromium and filtered chromium fraction exhibited "in-control" recovery results(Table 2-6).

Based on an overall assessment of MS/MSD and surrogate sample accuracy evaluation criteria, die water matrixanalytical data was acceptable for die SDG.

3-1

4.0 REPRESENTATIVENESS

Representativeness of the environmental sample analytical data was assessed using rm$*a*e blanks and laboratorymethod blanks and determining if holding time requirements were met. The environmental samples and associatedblanks were analyzed for the following target compound/analyte groups:

• Metals Anaiytes (Chromium)• Wet Chemistry Parameters (BOD, COD, Oil & Grease, & TSS

There were no rinseate or field blanks submitted for analysis with the samples. Laboratory method blanks wereanalyzed for target analytes in each listed category. Tables were prepared for the blanks only where reportedcontamination affected the analytical data. There were no tables required for this section because there was nocontamination noted in the associated method blanks.

If contaminants were detected in a blank, correcdve actions were made for the chemical analytical data during datavalidation by Heartland. The corrective action consisted of amending the laboratory reported results for organic andinorganic target analytes by the criteria. The following describes the Validation Qualifier code in the blank summarytables.

If VaJidannn Oj"l'*"fl' If a sample result for the blank contaminant was less than the sample CRDLwhen the absolute value of the negative blank value was greater than the CRDL, the sample resultfor the blank contaminant was amended as estimated non-detected.

• T Validj}""", QiffMfKr If a sample result for the blank contaminant was greater than die CRDL andless than 10 times the blank value, when the absolute of the negative blank value is greater than dieCRDL die result was amended as estimated at die laboratory value.

4.1 Method Blanks

The method blanks were a sample of deionized water that is prepared by the laboratory at die time of analysis.Method blanks undergo die same analytical process as die corresponding environmental samples and associated fieldblanks. The purpose of the method blank is to assess the potential for target analytes to "contaminate" the sampleduring analysis.

There were no target analytes reported in the associated mediod blanks which impacted sample data. Therefore, basedon assessment of mediod blanks for representativeness die analytical data was acceptable for die SDG.

4.2 Holding Time*

Holding times requirements are utilized in an effort to minimize die degradation or concentration of constituents ina particular matrix over time. The stability of the constituents is determined to the best extent by die regulatoryagencies. A reasonable time limit is imposed under which the samples must be extracted or prepared and dienanalyzed. The holding times regulations assume that die samples have been properly preserved according to dieguidelines, either at die laboratory or in die Meld. Analytical results from samples with holding time violations arequalified as estimated, J/UJ, because of die potential of compromising the sample. If die holding time is grosslyviolated (> 15 days) the results are qualified/rejected, J/R.

4-1

All holding time requirements, both preparadon and analydcal, were met by the laboratory for all fractions.

S.Q COMPARABILITY

Comparability is a qualitative measure designed to express the confidence with which one data set may be comparedto another. The analytical samples were collected and transported to the chemical analytical laboratory in accordancewith standard procedures and were analyzed in conformance with acceptable USEPA procedures (Refer to Table 5-1below). The analytical data are reported in standard units (micrograms per liter, micrograms per kilogram, etc.).

The methods used to collect the environmental samples and the methods used to analyze the samples should assurecomparability of the analytical data.
