TL;DR: In this article, the degradation process appeared to be pseudo first-order with respect to the organic compound, with the rate constant appearing to be directly proportional to the surface area to volume ratio and increasing with increasing degree of chlorination.

TL;DR: In this paper, the relative importance of these factors is scale-dependent and their relative impact on contaminant transport is evaluated for hydrophobic organic compounds, physical nonequilibrium (i.e., rate-limited mass transfer in aggregated or layered systems) and intraorganic matter diffusion (rate-limited diffusion within the sorbent organic matter matrix) are probably the predominant factors causing nonideality.

TL;DR: In this paper, a flow-through column test was conducted to investigate the products of degradation of trichloroethene (TCE) in contact with granular iron metal, and results indicated the degradation process to be pseudo-first-order and the rate constant to be relatively insensitive to the initial concentration of TCE over the range from about 1.3 to 61 mg/L.

TL;DR: The use of granular iron for in situ degradation of dissolved chlorinated organic compounds is rapidly gaining acceptance as a cost-effective technology for ground water remediation as discussed by the authors, and the first field demonstration of the technology is of particular importance since it provides the longest available record of performance (five years).

TL;DR: In this article, the authors show that if the zone of tension saturation extends to ground surface, then the addition of a very small amount of water can result in an immediate and large rise in the water table.
