Guidance to develop a structured approach for managing sites contaminated with chlorinated solvents and dense nonaqueous-phase liquids.

Practical recommendations for effectively characterizing, designing, implementing, and evaluating in situ remediation projects.

An overview of how to characterize, remediate, and monitor contaminated fractured rock sites, including developing conceptual site models, selecting tools, designing monitoring programs, and evaluating remediation strategies.

Provides tools for selecting and applying appropriate approaches for integrated site characterization and remediation at sites contaminated with dense nonaqueous phase liquids (DNAPLs).

Assists users without statistical expertise to understand groundwater statistical methods and apply statistical tools throughout each stage of a groundwater project. Includes common statistical methods, relevant study questions, and software tools.

Explains how remediation risk management can be used to identify and address technical challenges associated with groundwater cleanup at complex sites while maintaining long-term protection of human health and the environment.

Guidance to help site managers develop and adapt integrated strategies for understanding, treating, monitoring, and evaluating complex DNAPL-contaminated sites.

Explains how to develop and use performance specifications to evaluate the effectiveness of solidification/stabilization remedies, from treatability testing and implementation through long-term monitoring.

Guidance to evaluate, design, construct, monitor, and maintain permeable reactive barriers (PRBs) used as treatment zones to clean up contaminated groundwater.

Provides updated information on new developments and innovative approaches in applying PRBs to treat a variety of groundwater contaminants.
