TL;DR: A small-scale field test was initiated in September 1994 to evaluate the in situ remediation of groundwater contaminated with chromate using a permeable reactive barrier composed of a mixture of zero-valent Fe, sand and aquifer sediment as discussed by the authors.

TL;DR: Evidence is provided that secondary iron-bearing mineral products may enhance the capacity of zerovalent iron systems to remediate Cr in groundwater, either through redox reactions at the mineral-water interface or by the release of Fe(II) to solution via mineral dissolution and/or metal corrosion.

TL;DR: A detailed characterization of the underlying and adjacent soils of a chrome plating shop was performed to provide information on the extent of soil and aquifer contamination at the site and on the potential for offsite migration and environmental impact as mentioned in this paper.

TL;DR: In this article, the authors compare the performance of four different sampling approaches and devices, including electric submersible pumps and bailers, with conventional monitoring well data and a passive multi-layer sampling system (DMLS).

TL;DR: In this article, the authors evaluated sampling procedures for determination of aqueous inorganic geochemistry and assessment of contaminant transport by colloidal mobility, and found that those sampling devices which caused the least disturbance (i.e. turbidity) also produced the most reproducible samples irrespective of filtration.
