Hydrogeology Program

We try to understand the role of groundwater in the hydrologic cycle by integrating measurement and simulation. This work is carried out in the field, the laboratory, and on computers. The Hydrogeology Program at CSULB is supported by the Bert and Ethel Conrey Endowment.

Announcements and News Items:

February 2021 - The CSULB Hydrogeology group is collaborating with Arcadis and Clemson University to conduct a pilot study of thermal in-situ remediation of solvent plumes in groundwater. The technology increases the rate of biodegradation through heating of the subsurface by about 20 degrees celcius. Heating is accomplished through circulation of fluid between boreholes in the ground and solar collectors at the surface. The system will be tested at Vandenberg AFB in Central California. This work is being funded through the Department of Defense Environmental Security Technology Certification Program (ESTCP).

January 2020 - The Hydrogeology group at CSULB has received its second Editorís Choice award for a publication. Six months ago, a paper by former MS student Adam Hawkins one the award in Water Resources Research. This paper was led by Tanya Brosnan, a former MS student and know an Engineering Geologist with the California Department of Toxics Substances Control. This project showed that the ancient inhabitants of Rapa Nui (Easter Island) probably relied upon coastal groundwater seeps for drinking water during long dry periods. The Hydrogeology Journal Editorís choice award is given to the top 5 papers out of the more than 200 published in a given year. The article is being provided as open access in recognition of the award. Thank you Hydrogeology Journal and Congratulations Tanya! (Brosnan, T., M. W. Becker, and C. P.

December 2019 - CSULB has been funded by the NSF in collabration with CSU Northridge to study Hydrology on the Island of   Moorea (next to Tahiti) in French Polynesia. The objective is to understand how groundwater moves to and throught fringing reefs of high tropical islands and atolls.
