• Over view of SEDD

• Overview of ADR

• The Pilot Study�Design

� Results

• Evaluation of ADR and SEDD


INTRODUCTION


SEDD = Staged Electronic DataDeliverable


SEDD File(Stage 2a, 2b, 3, or 4)

• Stage 2a

• Method Quality Control Data

• Stage 2b

• Instrument Quality Control Data

• Stage 3• Allows for independent calculation of results

• Stage 4

• Captures raw instrument data files

SEDD = Staged Electronic DataDeliverable


ADR = Automated Data Review

• Developed by Laboratory Data Consultants(LDC) for the USACE

• Laboratory Tool - Allows laboratories toverify EDD completeness and contractcompliance.

• Data Review Tool - Allows data users toperform an automated data review againstproject-specific library measurementquality objectives.



ADR performs automated review of analyticaldata relative to project requirements.

SEDD/ADR PILOT TEST

Soil Removal Action at Arctic Surplus Salvage Yard ASSY• Phase 1

• Lead and PCBs in soil contaminants of concern

• Data review and validation completed

• Compare results of manual data review to automated data review

• Phase 2

• Semiannual groundwater monitoring

• Pesticides, PCBs, VOCs, and metals contaminants of concern

• Use SEDD/ADR as a tool for data review

• Compare 10% of ADR to manual reviews

PILOT TEST RESULTS – SEDDPARSING

• Logic was required in Parser Tool to limit parsing toa single pass-through.

• DTD validation was required in the Parser Tool toensure the file structure was correct beforeattempting to parse.

• XML technology was/is still evolving. Parser Toolwas designed to take advantage of changingtechnology.


PILOT TEST RESULTS – SEDDPARSING

�Translator was required in ADR to convertSEDD data content to ADR valid values.

�Project specific requirements must be relayedto the lab before SEDD files are created. ADRproject-specific library is used to relay projectrequirements.

�Working on XML output of reviewed files andADR Library.


PILOT TEST RESULTS – ADR

Elements Captured in the ADR Review

QAPP Compliance• Reporting Limits• Reporting Units• Target Analytes• Hold Times• Sample Receipt Temperature

Laboratory Batch QC• Assignment of Batches• Surrogates• Method Blanks• Laboratory Control Samples• Duplicates

Field QC Samples• Matrix Spike/Matrix Spike Duplicates• Equipment Blanks• Field Duplicates



Elements Not Captured in the ADR Review

• Calibrations

• Instrument Checks

• Raw Data

• Verification against COCs

• Recalculation of Results

• Completeness of Hard Copy



ADR results compared well to manual reviewresults

– ADR did not miss observations made in manual review– ADR resulted in more flags than manual review– ADR allows for adjustment of flags based on professional

judgment



The automated review flagged the PCB resultswhen the sample receiving temperature was 1.1and 6.2 degrees Celsius. Based on professionaljudgment, the manual reviewer did not flag theresults.



The automated review flagged the PCB results becauseof a matrix spike failure. The manual reviewer did notflag the results because the sample concentration wasgreater than 4x the spiking concentration.


SEDD/ADR PILOT TESTASSESSMENT

Review and validation time reduced byapproximately 30% assuming:

•10% of the data requires a level III or IV typevalidation

•A complete ADR project library is established bythe project chemist and distributed to thelaboratory prior to sample analyses

•A project chemist oversees the review andvalidation.


Greater time reductions may be realized:

• If analytical laboratories can capturecalibration data in the SEDD file

• Where level III or IV type validation is notrequired.

• On long-term monitoring and remediationprojects with reduced data validationrequirements and well established qualitycontrol requirements.

SEDD/ADR PILOT TESTASSESSMENT


SEDD/ADR PILOT TESTCHALLENGES

•Valid values between SEDD and ADR

•LIMS Systems

•Field Sizes


• SEDD data is easily parsed into existing data reviewsoftware.

• SEDD DTD and ADR CCS ensure quality laboratoryEDDs.

• ADR is a tool for the project chemist to perform 100%review of sample data according to pre-establishedproject library.

• Reduces time and effort to review project data andproduce quality assessment and completenessreports by approximately 30%.
