Inland Empire Branch Meeting

The Inland Empire Branch is pleased to present:

Dr. John A. Izbicki, PhD

"Hexavalent Chromium: Tracing Sources and Impacts in the Mojave Desert and Elsewhere"



Decision making at groundwater contamination sites is often controversial, with stakeholders commonly having different views on the source and extent of contamination. Dr. John A. Izbicki will discuss the extent of hexavalent chromium released from a natural-gas compressor station at the Hinkley Site in the Mojave Desert, and from naturally occurring sources. He will discuss a scaling system under development that provides a framework for visualization, discussion, and achieving stakeholder consensus in evaluating the extent of these impacts.


John A. Izbicki has worked for the U.S. Geological Survey for almost 40 years in Maryland, Massachusetts, and California. John obtained his Bachelor’s and Master’s Degrees from Pennsylvania State University. In 2000 while working for the USGS, John obtained his Ph.D. in Soil Physics from University of California, Riverside. Within California his studies have focused on understanding the physical hydrology of coastal and desert aquifer systems primarily through the application of chemical and isotopic tracers. Recent work includes studies of trace-element occurrence and management in aquifers, managed aquifer recharge, submarine groundwater discharge, and bacterial source identification in urban streams and near-shore ocean water. Dr. Izbicki has several patents, published more than 100 U.S. Geological Survey reports and journal articles, and worked internationally with the International Atomic Energy Agency, and the Indian and Chinese Governments. Dr. Izbicki was the California Groundwater Resources Association David Keith Todd Lecturer (southern section) for 2015, and received the California GRA Lifetime Achievement Award in 2015.
