Education: 

1991 - Illinois State University, B.S. in Geology with honors 1993 - Iowa State University, Field Methods in Hydrogeology 1994 - University of Iowa, M.S. in Geology • Illinois Licensed Professional Geologist #196-000933 • Certified General Site Worker for Hazardous Waste Operations and Emergency Response (HAZWOPER) pursuant to 29 CFR 1910.120 since 1997

Major Responsibilities: 

Randy Locke is the Coordinator of the Monitoring, Verification, and Accounting Program for the Midwest Geological Sequestration Consortium, one of seven regional partnerships selected by the U.S. Department of Energy to determine the best approaches for capturing and storing carbon dioxide that might otherwise contribute to global climate change. He is an Illinois Licensed Professional Geologist, a member of the National Ground Water Association since 2003 and a member of the Illinois Groundwater Association since 1995. He served the Illinois Groundwater Association for over 10 years in multiple capacities and was its Executive Committee Chair in 2004.

Since 1998, Randy and colleague Jim Miner have led a field-intensive research program funded by the Illinois Department of Natural Resources to compile and interpret hydrogeological and geochemical information from sites with high-quality natural communities (e.g., Illinois nature preserves). His research has included extensive hydrogeological and geochemical investigations, land use impact assessments, regional water resources assessments, and the application of field-based monitoring and measurement techniques.
