TL;DR: It is found that OM extracted from the clayey silt aquitard resembles young, not fully degraded plant-related material, while OM from the sandy sediments is more bioavailable and related to microbial biomass, while in situ OM supported growth and activity of a more diverse microbial community.

TL;DR: A detailed characterisation of the Van Phuc aquifer in the Red River Delta region, Vietnam, where high-As groundwater from a Holocene aquifer is being drawn into a low-As Pleistocene aquifers is reported, finds the largest temporal hydrochemical changes were found in the Pleistsian aquifer caused by groundwater advection from the Holocene Aquifer.

TL;DR: In this paper, a numerical model was developed that allows the prediction of the surface temperature distribution that is attained with an arbitrarily shaped intensity profile, as well as material properties and the absorption of laser energy at the surface.

TL;DR: In this paper, using microcosms experiments and hydrogeochemical and microbial community analyses, they demonstrate that methane functions as electron donor for methanotrophs, triggering the reductive dissolution of arsenic-bearing iron(III) minerals, increasing the abundance of genes related to methane oxidation, and ultimately mobilizing arsenic into the water.

TL;DR: In this article, the authors analyzed the geochemistry and mineralogy of a 46m-long sediment core drilled into the redox transition zone where a high As Holocene aquifer is juxtaposed to a low As Pleistocene Aquifer in the Red River delta, Vietnam.
