AUTHORS

Kharaka has been a research hydrogeochemist with the U.S. Geological Survey since 1975. His investigations have emphasized water-rock interactions in petroliferous sedimentary basins. Current research covers the fields of water-rock-gas interactions, CO₂ sequestration in saline aquifers, contamination from agricultural drainage and petroleum-produced water, and fluid-fault interactions. Kharaka has authored more than 100 scientific papers and book chapters and has delivered about 200 scientific presentations. He received his Ph.D. from the University of California, Berkeley in 1971.

Nancy spent over 20 years as a reservoir geologist in the oil industry before moving to the environmental field 5 years ago. At the Environmental Protection Agency, she is the Oklahoma Corporation Commission Underground Injection Control Program Manager and a member of the Ground Water Center. She received her M.S. degree in environmental engineering from Southern Methodist University in 2004.
