Journal ArticleDOI
Arsenic mobility and groundwater extraction in Bangladesh.
Charles F. Harvey,Christopher H. Swartz,A. B. M. Badruzzaman,Nicole Keon-Blute,Winston Yu,M. Ashraf Ali,Jenny Jay,Roger Beckie,Volker Niedan,Daniel J. Brabander,Peter M. Oates,Khandaker N. Ashfaque,Shafiqul Islam,Harold F. Hemond,M. Feroze Ahmed +14 more
TL;DR: The results of field injection of molasses, nitrate, and low-arsenic water show that organic carbon or its degradation products may quickly mobilize arsenic, oxidants may lower arsenic concentrations, and sorption of arsenic is limited by saturation of aquifer materials.
Journal ArticleDOI
Validation of an Arsenic Sequential Extraction Method for Evaluating Mobility in Sediments
TL;DR: The proportional distribution of As among extractant pools was consistent for subs samples of the wetland and for subsamples of the riverbed sediments, and intermethod variability between the sequential extraction procedure and a single-step hot concentrated HNO3/H2O2 acid digestion was investigated.
Journal ArticleDOI
Performance and design optimization of a low-cost solar organic Rankine cycle for remote power generation
TL;DR: In this article, the authors describe the design of a solar organic Rankine cycle being installed in Lesotho for rural electrification purpose, which consists of parabolic trough solar thermal collectors, a storages tank, and a small-scale ORC engine using scroll expanders.
Journal ArticleDOI
Mobility of arsenic in a Bangladesh aquifer: Inferences from geochemical profiles, leaching data, and mineralogical characterization
Christopher H. Swartz,Nicole Blute,B Badruzzman,A Ali,Daniel J. Brabander,Jenny Jay,James Besancon,Shafiqul Islam,Harold F. Hemond,Charles F. Harvey +9 more
TL;DR: Aquifer geochemical profiles of aqueous and solid phase parameters were measured in a field site in the Munshiganj district of Bangladesh where the groundwater is severely contaminated by As as discussed by the authors.
Journal ArticleDOI
Microbial Mobilization of Arsenic from Sediments of the Aberjona Watershed
TL;DR: In this article, the authors investigated the role of solid-phase arsenic mobilization in aquatic sediment microcosms and found that the dissolution of arsenate to arsenite accompanied iron arsenate dis solution, suggesting that reduction was driving dissolution.
