CreekSpeak Discusses the Invisible: Groundwater


Support Local Journalism


CreekSpeak, Putah Creek Council’s six-month series of community talks about the nature, culture, and history of our region, concludes on Thursday, Oct. 18, with a presentation on the groundwater resources that affect our daily lives. Dr. Thomas Harter will present a talk entitled “Groundwater and Life” as the sixth and final speaker in the CreekSpeak series. When you think of fresh water, you likely think of the water that you can easily see – water that is on the surface of the earth and flows downhill in streams such as Putah Creek. This surface water accounts for about 2/3 of the fresh water on earth. Join us as we learn from Dr. Harter about the remaining  1/3 of the earth’s fresh water – groundwater. Groundwater is hard to see and measure, but it’s a critical water source, especially in the Central Valley. In towns like Winters and Davis, much of our water drinking and agricultural water supply relies heavily on groundwater. Dr. Harter is nationally renowned for his expertise in groundwater quality protection and management. His talk will cover topics such as the connection between surface and groundwater, nitrates in groundwater and how they get there, disadvantaged communities, agriculture, individual food choices, and how ground water pollution impacts residents of Yolo County.  The presentation begins at 7pm at the Mary L. Stephens Davis Branch Library, Children’s Activity Room (315 E. 14th Street, Davis). CreekSpeak talks are free to Putah Creek Council members and open to the public. A $5 donation is requested from those who have not yet joined the Council.
