“Keeping Our Wells From Running Dry”

 The Central Valley of California produces about 250 different crops with an annual net worth of about $17 billion. Clearly, agriculture is the economic backbone of our region. However, this agricultural production is heavily dependent on the pumping of massive amounts of groundwater from the Central Valley aquifer system, especially during dry years. Recently, two years of drought and an increase in the amount of irrigated acreage (mostly on the east side) have led to a proliferation of newer, deeper wells.  As competition for groundwater increases, our water table is dropping. Some wells are running dry. This brings up an important question: Will the Central Valley aquifer system still be there for the agricultural community of tomorrow? In other words, is our current usage of the Central Valley aquifer sustainable?

        Chris Petersen has an MS in Hydrology from the University of Arizona and is a professional geologist and certified hydrogeologist in California. He has 26 years of experience in the planning and implementation of groundwater projects throughout California, many of which involve artificial recharge and conjunctive use facilities.  He is a principal hydrogeologist and project manager for West Yost Associates, in Davis, California. He will discuss how groundwater recharge in wet periods using recharge basins and wells could help to ensure the sustainable management of our groundwater resources. In his talk, he will show how this problem has been handled in other parts of the state and provide some thoughts on what the folks in Modesto can to do advance groundwater storage.  Hopefully it will spark some good discussion.
