− | + | 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. | |

ARTICLE SUMMARY | 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. | |
