YELLOWSTONE'S NATURAL CONTAMINANTS: SOURCE, FATE AND TRANSPORT OF AS, F, AND HG, FROM THERMAL WATERS
Abstract
Dr. Nordstrom and his colleagues have been sampling thermal waters for 28 years in Yellowstone National Park. Results from their work have shown that high concentrations of arsenic, fluoride, and mercury occur naturally in these thermal waters and the chemistry is quite complex with speciation being an important key to understanding element mobility.
