Journal of Contaminant Hydrology 

TL;DR: In this article, an overview of various aspects of mathematical modeling focused upon solute transport models, an introduction to statistical criteria and graphical displays that can be useful for model evaluation, and an example of model evaluation for a mathematical model of pesticide leaching.

TL;DR: In the past few years, as hazardous waste sites have been studied more often and in more detail, immiscible fluids have been encountered in the subsurface with greater frequency as discussed by the authors.

TL;DR: An intensive literature search on the distribution and concentration of the surface-dependent runoff water has been compiled and a representative concentration matrix consisting of medians and extreme values can be applied to long-term valuations and numerical modelling of storm water treatment facilities.

TL;DR: Permeable reactive barriers are an emerging alternative to traditional pump and treat systems for groundwater remediation as discussed by the authors, which has progressed rapidly from laboratory bench-scale studies to full-scale implementation.

TL;DR: A review of the principles behind the different approaches, summarizes methods used and evaluates the approaches based on the experience from the reported applications can be found in this paper, with a few exceptions, direct electrochemical measurement and rigorous interpretation of redox potentials dubious, if not erroneous.
