Our
project integrates field work, analytical work, laboratory
studies, thermodynamic property evaluation, and modeling
applications into the interpretation of water-rock interactions in
surface and ground waters with an emphasis on trace elements. A
major objective of the project is to develop, test, evaluate, and
apply analytical and modeling techniques to the interpretation of
trace element and redox geochemistry in natural waters. We have a
fully equipped analytical laboratory for determining major ions,
trace elements, and redox species in water. Our field studies
emphasize mined and unmined environments where oxidative
weathering of sulfide minerals forms acid waters, deep
crystalline-rock environments that might host radioactive waste,
and geothermal environments. Field sites have included the
Leviathan mine, CA, Iron Mountain mines, CA, the Summitville mine,
CO, the Upper Animas Basin, CO, the Crystal mine, MT, the Boulder
Creek watershed, CO, Fairbanks, AK, the Mojave Desert, CA, the
Questa mine, NM, the Stripa mine, Sweden, the Osamu Utsumi mine,
Brazil, the Morro do Ferro site, Brazil, and Yellowstone National
Park.
