Tetra Tech, Inc. DATA VALIDATION REPORT

LEVEL IV

Site: West Lake Landfill Site, Bridgeton, Missouri

Laboratory: TestAmerica Laboratories, Inc. (Earth City, Missouri)

Data Reviewer: Harry Ellis, Tetra Tech, Inc. (Tetra Tech)

Review Date May 15, 2018

Sample Delivery Group (SDG): J27436

Sample Numbers: AC-SED-11-EPA DUP

Matrix / Number of Samples: One Sediment Sample

The data were qualified according to the U.S. Environmental Protection Agency (EPA) Region 7

documents entitled "Contract Laboratory Program National Functional Guidelines for Inorganic

Superfund Methods Data Review" (9355.0-131), August 2014. In addition, the Tetra Tech document

“Review of Data Packages from Subcontracted Laboratories” (February 2002) and the EPA and others

document “Multi-Agency Radiological Laboratory Analytical Protocols Manual” (July 2004) were used

along with other criteria specified in the applicable methods.

The review was intended to identify problems and quality control (QC) deficiencies that were readily apparent from the summary data package. The following sections discuss any problems or deficiencies that were found, and data qualifications applied because of non-compliant QC. The data review was limited to the available field and laboratory QC information submitted with the project-specific data package.

I, Harry Ellis, certify that all data validation criteria outlined in the above-referenced documents were assessed, and any qualifications made to the data accorded with those documents.

DATA VALIDATION QUALIFIERS

U — The analyte was not detected above the reported sample quantitation limit.

J — The analyte was positively identified; the associated numerical value is the approximate concentration of the analyte in the sample.

UJ — The analyte was not detected above the reported sample quantitation limit, which is estimated.

R — The sample results are rejected due to serious deficiencies in the ability to analyze the sample and meet QC criteria. Presence or absence of the analyte cannot be verified.

DATA ASSESSMENT

Sample delivery group (SDG) J27436 included one (1) environmental sediment sample and no QC samples. The sample was analyzed for thorium and uranium isotopes by alpha spectroscopy, using DOE Method A-01-R, and for radium-226 and other isotopes by gamma spectroscopy, using EPA Method GA-01-R. The following summarizes the data validation that was performed.

ALPHA SPECTROSCOPY ANALYSES

I. Holding Time and Chain of Custody (COC) Requirements

The sample was received by the laboratory and analyzed within the established holding time of 6 months from sample collection to analysis. No data were qualified.

II. Matrix Spike/Matrix Spike Duplicate (MS/MSD)

MS/MSD analyses were not performed in these analyses. No qualifications were applied for this data gap. LCS and duplicate analyses provided adequate confirmation of accuracy and precision.

The laboratory duplicate analysis yielded a relatively low concentration of uranium-233/234, resulting in an excessive relative error ratio (RER) of 1.06 (versus the laboratory limit of 1.00). This was attributed to difficulty in homogenizing the sample due to the presence of stones and to the very low activity of the isotope, which leads to very few alpha particles counted by the instrument in the standard scan time. Due to this uncertainty in the true activity of those confounded isotopes, the sample result for uranium-233/234 was qualified as estimated and flagged “J”.

III. Blanks

The laboratory (method) blanks yielded no detectable activities, so no qualifications were applied.

IV. Laboratory Control Sample (LCS)

All percent recoveries from the LCS analyses were within established control limits. No qualifications were applied.

V. Tracers

The tracers (thorium-229 and uranium-232) yielded fully satisfactory recoveries from all samples. No qualifications were applied.

VI. Calibrations and other Quality Control Measures

All calibrations (including initial, annual verification, monthly, and daily) were within their QC limits. Monthly background checks were also within limits.

VI. Comments

The uranium-235/236 concentration was greater than the critical value, but less than the minimum detectable concentration; therefore, the result was considered non-detect and flagged “U”.

103I9025140007 4 SDG J27436

VII. Overall Assessment of Data

Overall data quality is acceptable, with no major qualifications applied. All data are usable as qualified for their intended purposes.

GAMMA SPECTROSCOPY ANALYSES

I. Holding Time and Chain of Custody (COC) Requirements

The sample was received by the laboratory and analyzed within the established holding time of 6 months from sample collection to analysis. The preferred 21-day ingrowth period was performed before determination of the radium and other isotopes. No data were qualified.

II. Matrix Spike/Matrix Spike Duplicate (MS/MSD)

MS/MSD analyses were not performed in these analyses. No qualifications were applied for this data gap. LCS and duplicate analyses provided adequate confirmation of accuracy and precision.

III. Blanks

The laboratory (method) blank yielded a low activity for lead-212. The detected activity of that isotope was more than 10 times the blank activity so no qualifications were applied.

IV. Laboratory Control Sample (LCS)

All percent recoveries from the LCS analyses were within established control limits. No qualifications were applied.

V. Tracers

Tracers are not used in this radioanalytical method.

VI. Calibrations and other Quality Control Measures

All calibrations (including initial, annual verification, and daily) were within their QC limits. Monthly background checks were also within limits.

VI. Comments

None.

VII. Overall Assessment of Data

Overall data quality is acceptable, with no qualifications applied. All data are usable as reported for their intended purposes.

CASE NARRATIVE

Client: Tetra Tech EM Inc.

Project: West Lake Landfill

Report Number: 160-27436-1

With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required.

TestAmerica St. Louis attests to the validity of the laboratory data generated by TestAmerica facilities reported herein. All analyses performed by TestAmerica facilities were done using established laboratory SOPs that incorporate QA/QC procedures described in the application methods. TestAmerica’s operations groups have reviewed the data for compliance with the laboratory QA/QC plan, and data have been found to be compliant with laboratory protocols unless otherwise noted below.

The test results in this report meet all NELAP requirements for parameters for which accreditation is required or available. Any exceptions to NELAP requirements are noted in this report. Pursuant to NELAP, this report may not be reproduced, except in full, without the written approval of the laboratory.

Calculations are performed before rounding to avoid round-off errors in calculated results.

All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below.

All solid sample results for Chemistry analyses are reported on an ""as received"" basis unless otherwise indicated by the presence of a % solids value in the method header. All soil/sediment sample results for radiochemistry analyses are based upon sample as dried and disaggregated with the exception of tritium, carbon-14, and iodine-129 by gamma spectroscopy unless requested as wet weight by the client.

Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative.

Reference the chain of custody and condition upon receipt report for any variations on receipt conditions and temperature of samples on receipt.

Manual Integrations were performed only when necessary and are in compliance with the laboratory’s standard operating procedure. Detailed information can be found in the raw data section of the level IV report.
