Water webinars

Join OCWD for its monthly webinar series on emerging and newsworthy topics. Hear from OCWD experts and District partners as they discuss important OCWD programs and projects that impact your water supply. Whether you are an elected official, water industry professional, researcher, consultant, student, or community member, there is something for everyone. Webinars last approximately one hour and are free to attend. 

December 14 at 10am - Seawater Intrusion Control in Orange County – Do We Need Another Barrier?

Orange County Water District has been investigating the nature and extent of seawater intrusion in the Sunset Gap area beneath the Naval Weapons Station Seal Beach. Southern California has four seawater intrusion barriers (two in Orange County) where water is injected via wells to create a high-pressure ridge underground that prevents seawater from moving inland and contaminating valuable groundwater. This webinar will highlight how OCWD has combated seawater intrusion in the Orange County Groundwater Basin for decades and take a deep dive into how it was discovered in Sunset Gap, what our investigation has shown, and potential barrier concepts based on groundwater modeling.
Featured speakers:
  • Roy Herndon, Chief of Hydrogeology, Orange County Water District
  • Chris Cassotta, Water Production Supervisor, City of Huntington Beach
