Role of in Situ Natural Organic Matter in Mobilizing As during Microbial Reduction of FeIII-Mineral-Bearing Aquifer Sediments from Hanoi (Vietnam)
Martyna Glodowska,Emiliano Stopelli,Magnus Schneider,Alexandra Lightfoot,Bhasker Rathi,Daniel Straub,Monique Sézanne Patzner,Vu T. Duyen,Michael Berg,Sara Kleindienst,Andreas Kappler +10 more
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.
Journal ArticleDOI
Spatial and temporal evolution of groundwater arsenic contamination in the Red River delta, Vietnam: Interplay of mobilisation and retardation processes.

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.
Journal ArticleDOI
Processes governing arsenic retardation on Pleistocene sediments: Adsorption experiments and model-based analysis
TL;DR: In this article, the results of anoxic batch experiments investigating arsenite adsorption onto Pleistocene sediments under a range of field-relevant conditions were reported, which indicated that the formation of solution complexes between organic buffers and Mn(II) ions promoted the oxidation of arsenite involving naturally-occurring Mn-oxides.
Journal ArticleDOI
Arsenic mobilization by anaerobic iron-dependent methane oxidation
Martyna Glodowska,Emiliano Stopelli,Magnus Schneider,Bhasker Rathi,Bhasker Rathi,Daniel Straub,Alexandra Lightfoot,Rolf Kipfer,Rolf Kipfer,M. van den Berg,Mike S. M. Jetten,Sara Kleindienst,Andreas Kappler +12 more
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.
Journal ArticleDOI
Deoxygenation prevents arsenic mobilization during deepwell injection into sulfide-bearing aquifers.
Henning Prommer,Henning Prommer,Jing Sun,Jing Sun,Lauren Helm,Bhasker Rathi,Bhasker Rathi,Adam J. Siade,Adam J. Siade,Ryan Morris +9 more
TL;DR: A sequence of three push-pull tests where the injectant was pretreated using acid amendment and/or deoxygenation was conducted to identify the processes controlling the fate of metal(loid)s and to understand the treatment requirements for large-scale CSG water injection.
