In the opening talk of this winter quarter's California Water Policy Seminar, UC Davis hydrology professor Graham Fogg debunked several common myths about groundwater:

• Pumping of ancient water in unsustainable
• Groundwater storage depletion always takes a long time to recover
• Groundwater levels tell us how much groundwater storage is changing 
• The quality of most groundwater is degraded
• Good quality groundwater today will likely stay that way
• Climate change will decrease groundwater recharge
