1.1 This guide pertains to corrective action monitoring before (baseline monitoring), during (remedy implementation monitoring) and after (post-remedy monitoring) sediment remedial activities. It does not address monitoring performed during remedial investigations, pre-remedial risk assessments, and pre-design investigations.

1.2 Sediment monitoring programs (baseline, remedy implementation and post-remedy) are typically used in contaminated sediment corrective actions performed under various regulatory programs, including the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Although many of the references cited in this guide are CERCLA-oriented, the guide is applicable to corrective actions performed under local, state, tribal, federal, and international corrective action programs. However, this guide does not provide a detailed description of the monitoring program requirements or existing guidance for each jurisdiction. This guide is intended to inform, complement, and support but not supersede the guidelines established by local, state, tribal, federal, or international agencies.

1.3 This guide provides a framework, which includes widely accepted considerations and best practices for monitoring sediment remedy efficacy.

1.4 This guide is related to several other guides. Guide E3240 provides an overview of the sediment risk-based corrective action (RBCA) process, including the role of risk assessment and representative background. Guide E3163 discusses appropriate laboratory methodologies to use for the chemical analysis of potential contaminants of concern (PCOCs) in various media (such as, sediment, porewater, surface water and biota tissue) taken during sediment monitoring programs; it also discusses biological testing and community assessment. Guide E3382 describes the overall framework to determine representative background concentrations (including Conceptual Site Model [CSM] considerations) for a contaminated sediment site; Guides E3344 (methodologies for selecting representative background reference areas) and E3242 (statistical and chemical methodologies used in developing representative background concentrations for a sediment site) complement Guide E3382.

1.5 Units—The values stated in SI or CGS units are to be regarded as the standard. No other units of measurement are included in this standard.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
