Environmental Geochemistry

The Environmental Geochemistry pursue experimental approaches that combine field and laboratory investigations with state-of-the-art spectroscopic and microscopic imaging techniques (principally using the Advanced Light Source at Berkeley Lab, and the Stanford Synchrotron Radiation Light Source at SLAC). They work with the Geochemistry Department’s Reactive Transport group to develop an integrated understanding of complex environmental and geochemical systems..

Currently the research focus for this group is on:

  • Contaminant transport and speciation, especially in biostimulated systems
  • Chemical weathering, including the kinetics of mineral precipitation and dissolution

Researchers include: Peter Nico, Carl Steefel, Mark Conrad, John Christensen, Pat Dobson, Ben Gilbert, Nigel Quinn, Eric Sonnenthal, Nicolas Spycher, Jim Davis, Will Stringfellow, Jill Banfield, *Kristie Boering, *Laura Lammers, *Gary Sposito, Markus Bill, Shaun Brown, Xin Ding, Patricia Fox.  *LBNL faculty scientists also associated with UC Berkeley.

In addition to their access to the synchrotron-based beamlines at the National Laboratories, the Environmental Geochemistry group maintains a state-of-the-art ICPMS facility consisting of a Perkin-Elmer Elan DRC-II with a dedicated HPLC system for speciation studies. In addition, they have added capabilities for surface area measurement, along with measurement of both total inorganic and organic carbon.
