Managed Aquifer Recharge in California

Timothy Parker and Graham Fogg discuss the benefits and the challenges of Managed Aquifer Recharge, and how MAR can be key to water security in a changing climate

From Maven’s Notebook:

Groundwater is an essential water source, providing 35% of the fresh water used in California, and significantly more in drought years.  However, when groundwater is used more rapidly than it is naturally replenished, actions must be taken to correct the imbalance, and one of the tools used by groundwater managers is managed aquifer recharge (or MAR).

Managed Aquifer Recharge (MAR) enhances the recharge rate by creating artificial streams and ponds where water trickles into the ground, or by using wells to directly inject water underground. MAR can also be used to improve groundwater quality and prevent some of the negative consequences of groundwater depletion, like ground sinking (subsidence) or the intrusion of salty groundwater from the oceans into coastal freshwater aquifers.

In an American Geosciences Institute webinar, Timothy Parker, principal hydrogeologist at Parker Groundwater, discusses managing groundwater storage and managed aquifer recharge in California.  Next, Graham Fogg, from UC Davis discusses recharge and reservoir management and keys to water security.
