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 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 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
