The Sample Conceptual Site Model Guidance Sample Clauses

The Sample Conceptual Site Model Guidance. For all sites, the Contractor shall prepare or update site CSMs following DQOs and UFP-QAPP worksheet #10. The CSM is a comprehensive written and graphical description of all available information about site conditions that could influence remedy design, selection, or performance. Thus, the CSM forms the basis of the understanding of the site and is the foundation for defining Remedial Action Objectives (RAOs) and for developing and implementing a remediation strategy. A CSM incorporates several elements, including the following: • Three-dimensional representation of: o Nature and extent of contaminant (including source types and affected media); o Site geology; o Site hydrogeology; o Biological and geochemical conditions; o Monitoring points; • Contaminant fate and transport in the environment; • Risks, receptors and potential receptors (under current and reasonably expected future exposure scenarios); • Past remedial actions and locations of remedial components and monitoring points; • Historical, current, and expected future land uses; and • Other factors relevant to the understanding of contamination at the site.1 The Contractor shall develop initial or updated CSMs for all sites listed in Table 1 of this PWS. An appropriately detailed CSM is required beginning with the remedial investigation phase for all restoration program sites and must be maintained until the end of the project life. A CSM must be updated as new data and site knowledge are acquired. This is crucial for assessing and optimizing remedy performance, and monitoring programs.2 Additional detail is included in but not limited to the following references: USEPA Groundwater Road Map (OSWER Directive No. 9283.1-34, 2011) and Environmental Cleanup Best Management Practices: Effective Use of the Project Life Cycle Conceptual Site Model (EPA 542-F-11-011, 2011), ITRC guidance (ITRC, 2004 and 2006) and ASTM International (formerly known as American Society for Testing and Materials) standard designations E1689 (2014) and D5979 (2014).
