Arsenic Research

USGS Workshop on Arsenic in the Environment, February 21-22, 2001, Denver, CO. Extended Abstracts.

Our project investigates the occurrence, distribution, mobility, and fate of arsenic in geothermal systems, mine sites, and surface and ground waters to improve our understanding of processes affecting arsenic in the environment. Our investigations include the evaluation and application of hydride-generation atomic spectroscopy for As(III/V) determinations in acid, metal-rich waters and the stability of As redox states in the presence of inorganic and microbial redox-active agents. An extensive bibliography on arsenic for the website is maintained by our project.
