Phase 1 Characterization Sampling and Analysis Plan West Valley Demonstration Project


Book Description

The Phase 1 Characterization Sampling and Analysis Plan (CSAP) provides details about environmental data collection that will be taking place to support Phase 1 decommissioning activities described in the Phase 1 Decommissioning Plan for the West Valley Demonstration Project, Revision 2 (Phase I DP; DOE 2009). The four primary purposes of CSAP data collection are: (1) pre-design data collection, (2) remedial support, (3) post-remediation status documentation, and (4) Phase 2 decision-making support. Data collection to support these four main objectives is organized into two distinct data collection efforts. The first is data collection that will take place prior to the initiation of significant Phase 1 decommissioning activities (e.g., the Waste Management Area [WMA] 1 and WMA 2 excavations). The second is data collection that will occur during and immediately after environmental remediation in support of remediation activities. Both data collection efforts have a set of well-defined objectives that encompass the data needs of the four main CSAP data collection purposes detailed in the CSAP. The main body of the CSAP describes the overall data collection strategies that will be used to satisfy data collection objectives. The details of pre-remediation data collection are organized by WMA. The CSAP contains an appendix for each WMA that describes the details of WMA-specific pre-remediation data collection activities. The CSAP is intended to expand upon the data collection requirements identified in the Phase 1 Decommissioning Plan. The CSAP is intended to tightly integrate with the Phase 1 Final Status Survey Plan (FSSP). Data collection described by the CSAP is consistent with the FSSP where appropriate and to the extent possible.




Phase 1 Final Status Survey Plan for the West Valley Demonstration Project


Book Description

This plan provides the technical basis and associated protocols to support Phase 1 final status survey (FSS) data collection and interpretation as part of the West Valley Demonstration Project Phase 1 Decommissioning Plan process. This plan is consistent with the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM). The Phase 1 Decommissioning Plan provides the relevant derived concentration guideline levels (DCGLs) for the Phase 1 radionuclides of interest. This plan includes protocols that will be applied to the deep excavations planned for Waste Management Area (WMA) 1 and WMA 2, for surface soils outside the WMA 1 and WMA 2 excavations that do not have contamination impacts at depths greater than one meter, and for areas that are used for Phase 1 contaminated soil lay-down purposes. All excavated and lay-down areas will be classified as MARSSIM Class 1 areas. Surface soils that have not been excavated, are not expected to exceed DCGLs, and do not have contamination impacts at depths greater than one meter will be divided into either Class 1 or Class 2 areas depending on the expected potential for surface soil contamination in those areas. The plan uses gamma scans combined with biased soil samples to address DCGLemc concerns. The plan uses systematic soil sampling combined with area factors to address DCGLw and DCGLemc concerns. The Sign test will be used to statistically evaluate DCGLw compliance. If the results from the characterization sampling and analysis plan (CSAP) data collection indicate that background may be a significant issue for Sign test implementation, the Wilcoxon rank sum (WRS) test will be used instead to demonstrate DCGLw compliance. A reference area will be selected on the basis of CSAP data results if the WRS test becomes a necessity. The WMA 1 excavation footprint includes approximately 476 foundation pilings that will be trimmed and left in place. Piling-specific systematic and biased sampling will be conducted to address concerns that these pilings may have served as preferential flow pathways into the underlying Lavery till. Phase 1 FSS data collection results will be summarized, presented, and interpreted in one or more FSS reports.






















Site Characterization


Book Description

Site Characterization Sampling and Analysis HMTRI Site Characterization: Sampling and Analysis is an introductory environmental sampling textbook intended for use in community/technical college environmental technology curricula or in industrial training programs. Comprehension of the subject matter is enhanced by associated coursework in chemistry, biology, environmental regulations, and college-level mathematics. The goal of the present textbook is to provide the environmental technician with the knowledge and skills necessary to assist a site characterization project planner in the sampling and monitoring process. Among the tasks the students will learn how to perform are: * assisting the research of a site's background for data that a project manager will use in the development of a site sampling plan * meeting representative sampling objectives and quality control/quality assurance objectives * preparing to go onsite for a sampling event * monitoring a site for potentially hazardous atmospheres * following the sampling plan in collecting samples from various media (e.g., soil, surface water, ground water, and containers) * troubleshooting under unforeseen circumstances * preparing samples for transport to the laboratory * documenting field activities * communicating with laboratory personnel * interpreting lab reports, including the validation of quality control data The text contains photographs and line drawings to help students visualize equipment and processes. Included are instructional aids such as chapter objectives, concept statements before major sections, review questions (as well as application and critical thinking activities) after each section, and a glossary of the terminology.
