The ITRC Integrated DNAPL Site Strategy (IDSS) Team intends this guidance document to assist site managers in developing an integrated DNAPL site management strategy containing five key features:
- a conceptual site model (CSM) based on reliable characterization methods and an understanding of the subsurface conditions that control contaminant transport, reactivity, and distribution
- remedial objectives and performance metrics that are clear, concise, and measureable
- treatment technologies applied in sequence or in parallel designed to optimize performance and take advantage of potential synergistic effects
- monitoring strategies based on interim and final cleanup objectives, the selected treatment technology and approach, and remedial performance goals
- reevaluating the strategy repeatedly and even modifying the approach when objectives are not being met or when alternative methods offer similar or better outcomes at lower cost
