Presentation Summary

The California State Water Resources Control Board was required to create a statewide comprehensive groundwater quality monitoring program in 2001 as a result of Assembly Bill 599 (Liu, 2001). This legislation also required all information to be publicly available. In addition to the online GAMA Groundwater Information System to query and download groundwater quality data, the GAMA Program’s Online Tools webpage provides an ever-increasing list of spatially interactive web applications to address many groundwater issues including groundwater quality trends, groundwater age, well construction, contamination to small system and domestic wells, and risk to contaminated groundwater. The GAMA Program is implemented in cooperation with the U.S. Geological Survey, LLNL, and CA State University East Bay.


Dori Bellan is an engineering geologist for the State Water Board’s GAMA Program. Dori attended Eastern Kentucky University for her undergraduate studies in Geology. Her graduate studies at the Center for Earthquake Research and Information at the University of Memphis were in geophysics and paleoseismology, in cooperation with the USGS. She has worked in the GAMA Program since 2005 and enjoys performing spatial analyses, employing new data technologies to better understand groundwater conditions, and communicating groundwater issues to the public with outreach and visual tools.
