TL;DR: The rheological properties of xanthan gum solutions were obtained under various chemical and environmental conditions relevant to delivery of remedial amendments to groundwater and it was shown that the consistency index is a linear function of the xantha concentration.

TL;DR: The rate of U(VI) reduction by BrY is comparable or better than rates reported for other metal reducing species, and the reaction kinetics necessary to apply this for remediation processes have not been adequately defined.

TL;DR: In this article, the authors derived equations for the steady-state oxygen concentration profiles which are expected to develop as a result of simultaneous oxygen diffusion and consumption in hydrocarbon contaminated soils, and used these equations to estimate the maximum oxygen penetration distance and the total cleanup time for several environmental scenarios such as surface and subsurface soil contamination as well as contaminated soil piles.

TL;DR: Foam delivery was shown to mitigate the mobilization of highly mobile contaminant from sediments, and achieved more uniform amendment distribution in a heterogeneous unsaturated system, and demonstrated remarkable increasing in lateral distribution of the injected liquid compared to direct liquid injection.

TL;DR: The major processes for deep vadose zone metal and radionuclide remediation are reviewed, finding efforts to remove contaminants have generally been unsuccessful although partial removal may reduce downward flux.
