Fundamental Study of the Delivery of Nanoiron to DNAPL Source Zones in Naturally Heterogeneous Field Systems

Abstract

Chlorinated solvent DNAPLs can be consistent long-term sources of groundwater contamination. Remediation is costly and poses significant technical challenges. Nanoiron (NZVI) is a proposed in situ remediation agent for DNAPL source zones, but the effectiveness of NZVI treatment relies on the ability to emplace and retain the NZVI near or within the DNAPL source area. The dominant physical and chemical processes controlling the reactivity and migration and distribution of NZVI in the subsurface are poorly understood, however, making it difficult to ensure that NZVI will be delivered where it is needed and whether or not it can be an effective treatment alternative for DNAPL source zones.
