  1. VSP*at the River Corridor Closure Project at the Hanford Site ASP 2011 Workshop Pleasanton, California Jim Davidson Senior Scientist Sample Design and Cleanup Verification Washington Closure Hanford, LLC. Richland, Washington * Visual Sample Plan

  2. Summary • Introduce WCH at the Hanford Site • VSP for Focused Sampling • VSP for Statistical Sampling • VSP for Focused and Statistical Sampling • VSP for Confirmatory Sampling • Challenges and Suggestions for the Future • Questions

  3. WCH Washington Closure Hanford manages the $2.4 billion River Corridor Closure Project for the U.S. Department of Energy’s Richland Operations Office. The company is responsible for protecting the Columbia River by cleaning up an estimated 560 waste sites, demolishing 328 buildings, placing two plutonium production reactors and one nuclear facility in interim safe storage, and operating the Environmental Restoration Disposal Facility.

  32. Challenges and Suggestions for the Future • VSP GUI Improvements • Adjustable font size for sample location labels • Copy and paste text labels • Undo and redo of more GUI objects • Visible grid lines • One-click snap-to-connect for X and Y axes • MARSSIM Sign Test as Surrogate for WAC Three-Part Test • ESL simulation and statistics language • E = Easy, Environmental, Extensible • S = Sampling, Simulation, Statistics • L = Language, Library, Laboratory • ESL uses Data Matrix Algebra (DMA) • DMA has simplicity of scalar algebra, power of matrix algebra • ESL-2 with data handling language that works with Excel • VSP menu options are finite; a simple ESL language is unlimited
