Idaho Falls, Idaho
During the Sr-90 breakout group discussion of the Environmental Remediation Science Program Workshop held June 12-14, 2006 at INL, copies of the “Operable Unit 3-14 Tank Farm Soil and Groundwater Remedial Investigation/Baseline Risk Assessment” document were requested. This document has been approved for external release as: DOE/NE-ID-11227, REV 0, with Lorie Cahn, Michael L. Abbott, John F Keck, Peter Martian, Annette L. Schafer, and Michael C. Swenson as authors.
The complete document is very long as indicated by the multiple “PDF files” required to present it.
