Recharge…What is it good for? Everything! (Salon 1)
Moderator: Adam Hutchinson, Orange County Water District

Join us as we explore the wide-ranging benefits of managed aquifer recharge (MAR). MAR goes beyond just aquifer replenishment and raising groundwater levels. MAR projects, when well-planned and coordinated, can support flood risk reduction, ecosystem enhancement, subsidence mitigation, agricultural land preservation, a flexible water supply for multiple purposes, improved water quality, and drought resiliency. This two-part session hopes to inspire MAR practitioners to look beyond sustainable groundwater management and look instead to sustainable water resources management.

Oil, Gas and Groundwater (Salon 4)
Moderator: Ted Johnson, Water Replenishment District of Southern California

Protection of groundwater from oil and gas activities such as well stimulation, produced water, and underground fluid injection remain an area of critical concern in California and beyond. Questions include 1) Where are protected groundwater resources? 2) How close are oil and gas operations to protected groundwater and what is the geology between the two? 3) Is there evidence of oil and gas fluids mixing with protected groundwater and if so, how did they get there? and 4) Have oil and gas operations impacted and changed water quality in groundwater basins? The USGS, in partnership with state and federal agencies, is working to help answer these questions through a detailed framework of cutting-edge scientific research and mapping studies in numerous California oil and gas fields that overlie or are near protected groundwater. Results are starting to be released and will be shared with the audience at this informative conference session.
