US environmental programs (e.g. the Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP) fund cutting-edge environmental projects. Here, articles are written by invited experts (see Contributors), edited by leaders in this field (see Editors), and aim to introduce and summarize current knowledge to environmental project professionals on topics using cross-linked references to reports and technical literature. The library archives summarize and make accessible additional resources relevant to all environmental professionals. FEATURED ARTICLES (Updated Regularly) In Situ Chemical Reduction - ISCR CONTRIBUTORS: Dr. Paul Tratnyek ARTICLE SUMMARY In situ chemical reduction (ISCR) refers to the in situ groundwater remediation approaches that principally involve contaminant treatment by chemical reduction. ISCR can occur via natural bigeochemical processes, catalyzed by in situ microbial activity, or by adding chemical reductants. In this article, we introduce the basic principals and comment on the use of ISCR in remediation activities including outlining the common ISCR technologies available with links to more information. pH Buffering in Aquifers CONTRIBUTORS: Dr. Miles Denham ARTICLE SUMMARY Buffering of pH – the resistance to pH change – in groundwater systems can be an important control on contaminant attenuation or degradation processes. All aquifers have some natural buffering capacity, but in many cases the pH buffering capacity must be augmented to achieve optimum remediation performance. This is particularly true for remedial processes that generate acid such as microbial degradation of chlorinated solvents. Considerations in choosing amendments for enhancing aquifer-buffering capacity are achieving the correct dose, the longevity of it in the aquifer, and any collateral effects. LIBRARY (Documents/Reports/References) Helpful documents and reports have been collected and summarized in the ER Library for easy access. Documents are pulled from some of the leading organizations in environmental restoration reseach and applications and include content covering a wide variety of topics.
