Sorption of Fe(II) and As(III) on goethite in single- and dual-sorbate systems

Experiments were conducted to quantify Fe(II) sorption onto goethite in the absence and presence of As(III). The experimental data obtained in single-sorbate experiments were modeled using a diffuse double layer surface complexation model and used to predi ...

Solar oxidation and removal of arsenic at circumneutral pH in iron containing waters

Urs von Gunten

An estimated 30-50 million people in Bangladesh consume groundwater with arsenic contents far above accepted limits. A better understanding of arsenic redox kinetics and simple water treatment procedures are urgently needed. We have studied thermal and pho ...

Behavior of arsenic and other redox-sensitive elements in Crowley Lake, CA: A reservoir in the Los Angeles Aqueduct System

Janet Gordon Hering

Elevated arsenic concentrations in Crowley Lake derive from upstream geothermal inputs. We examined the water column of Crowley Lake under stratified and unstratified conditions, seeking evidence for algal uptake and transformation of arsenic and its depos ...

Arsenic occurrence and speciation in municipal ground-water-based supply system

Janet Gordon Hering

The city of Hanford, California, relies on ground water for its municipal water supply. Arsenic concentrations in local wells frequently exceed the current drinking water standard (50 μg/L), although some dilution is achieved within the distribution system ...

Rapid oxidation of geothermal arsenic(III) in streamwaters of the eastern Sierra Nevada

Janet Gordon Hering

Arsenic redox cycling was examined in source waters of the Los Angeles Aqueduct, specifically at Hot Creek, a tributary of the Owens River. Elevated arsenic concentrations in Hot Creek result from geothermal inputs. Total arsenic and As(III) concentrations ...
