The Recharge Initiative has been established as a comprehensive research, service, and teaching program at UCSC, to help improve the quantity and quality of groundwater resources!

Learn more about The Recharge Initiative, including how you can participate, collaborate, and/or contribute...

HotI do not plan to admit graduate students to join the UCSC Hydrogeology Group during the 2024-25 cycle.

I do not plan to add postdocs to the UCSC Hydrogeology Group.

This site needs to be updated! This is a project for Summer 2024, along with migration to a more stable server...
