Short description: To help managers develop successful integrated strategies for chlorinated solvent sites, this document describes key concepts and recent developments in each of five areas: (1) a conceptual site model based on reliable characterization methods and an understanding of the subsurface conditions that control contaminant transport, reactivity, and distribution; (2) remedial objectives and performance metrics that are clear, concise, and measurable; (3) treatment technologies applied in sequence or in parallel designed to optimize performance and take advantage of potential synergistic effects; (4) monitoring strategies based on interim and final cleanup objectives, the selected treatment technology and approach, and remedial performance goals; and (5) re-evaluating the strategy repeatedly and modifying the approach when objectives are not being met or when alternative methods offer similar or better outcomes at lower cost
