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.
