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

Introduces a six-step remedy selection framework to assist decision-makers in identifying which contaminated sediment remedial technology is most favorable for a site.

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.

Provides the technical and related regulatory considerations for in situ bioremediation of chlorinated ethene dense, nonaqueous-phase liquids source zones.

Six critically reviewed case studies of recent or ongoing applications of in situ bioremediation at sites with dense, nonaqueous-phase liquid source zones.

Overview of in situ bioremediation and some of the issues to consider when selecting and designing an ISB system for remediation of chlorinated ethene DNAPLs source zones.

Provides guidance for the systematic characterization, evaluation, and appropriate design and testing of ISB for any biotreatable contaminant.

Presents and discusses regulatory processes appropriate to a variety of active bioremediation techniques for chlorinated solvents in ground water.
