Integrating DNAPL Site Solutions Web-Document: NOW AVAILABLE!
The widely popular ITRC document, published in 2011, is now available as an interactive Web document! Originally a downloadable PDF, the Integrated DNAPL Site Strategy (IDSS) guidance document describes key concepts and recent developments to help remediation managers develop successful integrated strategies for chlorinated-solvent sites. 

The IDSS is a very important document because the more recent DNAPL documents (Integrated Site Characterization, Characterization and Remediation of Fractured Rock, and Optimizing Injection Strategies and In situ Remedial Performance) cite it in their linkages and serve as their foundation. Now the reader will be able to click on a link in any of the three documents above and be transported to the appropriate sections within the IDSS document and navigate freely. All links in this updated document are fully interactive, linking to additional resources and references, as ITRC strives to make their documents more user-friendly.
About this Document

The ITRC Integrated DNAPL Site Strategy 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 based on absolute and functional objectives. The functional objectives conform to SMART attributes (i.e., specific, measurable, obtainable, relevant, and time-bound).
  • 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 - even modifying the approach when objectives are not being met or when alternative methods offer similar or better outcomes at lower cost.
ITRC is a program of the Environmental Research Institute of the States (ERIS). ERIS is a 501(c)(3) organization incorporated in the District of Columbia and managed by the Environmental Council of the States (ECOS).
