TL;DR: In this paper, the authors reviewed the aqueous geochemistry of chromium, especially with reference to the recent work of Rai et al. (report EPRI EA-4544, 1986, Report EPRi EA-5741, 1988), and showed that the chromium content of natural waters is generally low whereas rocks exhibit a wide range of Cr concentrations.

TL;DR: The iron mineralogy of aquifer sediments was described by chemical extraction techniques and a rapid indication of the redox status of a sediment sample can be achieved by a 0.5 M HCl extraction.

TL;DR: In this article, the chemical changes in the infiltration flow path from the Lot River to an adjacent aquifer were followed using chloride as an indicator of physical mixing of the river water with groundwater.

TL;DR: This study finds that montmorillonite edge surface chemistry models that account for the "spillover" of electrostatic potential from basal onto edge surfaces and for the stabilization of deprotonated Al-Si bridging sites through bond-length relaxation at the edge surface can reproduce key features of the best available experimental titration data.

TL;DR: In this article, the pore space of water-saturated bentonite is divided into macropore and interlayer nanopore compartments, and the relative contributions of pore-network geometry and diffusive behavior of water molecules near montmorillonite basal surfaces are determined quantitatively.
