Description
We are conducting a study examining arsenic fate and transport near an abandoned arsenopyrite mine in Floyd County, Virginia. The mine was operable in the late 1800s and early 1900s and produced arsenic trioxide, which was shipped to pesticide manufacturing plants. Although the mine shafts are closed, there are several waste piles at the site which contain arsenopyrite, scorodite (a weathering product of arsenopyrite) and iron oxides. These waste piles provide a continual source of arsenic to a local stream. One of our objectives is to examine the attenuation of arsenic in the unsaturated, saturated, and hyporheic zones, as well as the stream. Collaborators include Maury Valett and Jake Chaffin of the Biology Department at Virginia Tech.
