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. 



On September 29 at 10am, our webinar will focus on OCWD's groundwater cleanup efforts, particularly in the North Basin where industrial chemicals have impacted an area of the Orange County Groundwater Basin. 

Plumes created by past manufacturing are spreading and threaten to impact the basin. The District is proactively seeking ways to clean up the pollution in a united effort with local and national regulatory agencies. The initial cleanup efforts are focused on cutting off and preventing the spread of contamination before it travels further into the main aquifer supplying hundreds of potable supply wells.

Featured Speakers: 

  • Dave Mark, Principal Hydrogeologist, Orange County Water District
  • Maile Gee, Engineering Geologist, Santa Ana Regional Water Quality Control Board
