A Comprehensive Computer Application for Managing Sample Planning, Electronic Data Manipulation and Data Validation and Verification in Support of the MARLAP Principles 2008 RETS REMP Conference Charlotte, NC June 23 – 25, 2008 Eric Darois, CHP Radiation Safety and Control Services, Inc. Stratham, NH

The Problem Your project starts off slow and grows exponentially Sample results are flying in Data kept in 5 different spreadsheets by 5 different people Everybody is hand typing in results The Chaos Grows…

Where’s my Data I think it’s here somewhere …

MARLAP Iterative Data Life Cycle Integration Impacts Cost and Success

MARLAP Principles Directed Planning –Analytical Protocol Specifications (APS) Data Quality Objectives, DQOs –Measurement Quality Objectives, MQOs Implementation –Sampling & Analysis Data Quality Assessment, DQA –Verification –Validation

Analytical Protocol Specifications, APS Developed for each analysis type as a “short” document Contents of Document –Required Analytes –Applicable Matrix (water, soil, vegetation, etc) –QC Frequency –COC Requirements –Applicable MQOs Allows for effective V&V and DQAs

Measurement Quality Objectives, MQOs Considered the analytical portion of the DQOs –Project Specific (i.e. REMP may be different than GW Investigations) Examples –Required Uncertainty at a defined Action level (i.e. at 200 pCi/L, 1 sigma uncertainty must be <20%) –MDA at Background –Detectability in the presence of interfering nuclides –Range of measurement –Report All Results (+ or -) with Uncertainty May be Quantitative and Qualitative Statements

MARLAP Roadmap

MARLAP Implementation May Be Challenging To Implement For Large Continuous Projects RSCS Analytical Data Management System Designed to Manage MARLAP Principles

Software/Database Environment SQL Database Coded in Visual Basic.net 2.0 framework User-Friendly Screens Adaptable to any sampling and analysis regimen RETS, REMP, NPDES, Chemistry, CERCLA, FSS, etc. Manages data from multiple sites and multiple projects Reports generated by Crystal Reports Hierarchy of user access privileges protection on a site level Tracks all changes made to old and new data Stand-alone or fully networked computer installation Automatic updates

ADMS and MARLAP Specify Quantitative DQOs and MQOs –Analytes/Labs/MDAs/DL -APS –Action Levels and Notifications –Alpha and beta error rates by project –Multiple Labs with different capabilities Directed Sample Planning –Project Specific or Recurrent Scheduling (date or frequency weekly, monthly, quarterly, etc.) –Assigns Unique Sample ID –Collection Information (Who, What, When, Where) by Media Class –Chain of Custody Records (Fully Electronic) –Store ANY file into DB (pdf, html, doc, etc)

ADMS and MARLAP Data Quality Assessment, DQA –EDD Import (any CSV format!) No more data input, No more typos –Data Verification on Import Missing Analytes & Samples –Data Validation Reports Sample Schedule Adherence Analyte Trend Reports RMU Reports –Individual & Group Statistical Reports

ADMS Standard Reports Admin Reports –Action Level and Discrimination –Analysis Codes Summary Report –Lab Summary Report –Location Summary Report Sample Reports –Sample Results –Chain of Custody –Assigned Sample Plan –Generate Barcodes Report –Histogram Report –Sample Plan (Uncollected Samples) Missed Frequency Report –Sample Status Report –Trend Report –Regression Analysis Report

Histogram Reports 6 Bins 21 Bins, Same Data

ADMS Barcode Report

ADMS Key Additional Features GPS Coordinates Optional – Each Sample Location >800 Nuclides and Chemicals Pre- Loaded Unit Conversions – Import and Unit and Convert to Desired Base Duplicate Results Utility Unlimited Action Level Types by Media Fully Supports Sample Barcode Labels Custom Import Format Outputs suitable for export into reports or Spreadsheets

Future Changes Develop Separate Software for Field Collection –Current Version allows for Planned Samples to be “Assigned” for Collection –“Paperless” Environment

Life with ADMS
