JoeOrange County Sanitation District operates a state-of-the-art Environmental Sciences Laboratory. The Lab provides services for the Sanitation District’s operations, compliance, and source control activities.

It is staffed by some of the most qualified and experienced individuals in the laboratory testing industry. The lab is accredited by the California Department of Health Services-Environmental Laboratory Accreditation Program.

  • Various stages of wastewater treatment processes
  • Industrial wastewater discharge sites
  • Water from the Pacific Ocean near the ocean release pipeline
  • Water and sediments from the surf-zone, the Santa Ana River and storm drains
  •  Air samples from Digesters and Central Generation Power engines
  •  Sediment samples within OCSD discharge point

The lab work is regulated by the Environmental Protection Agency (EPA), the Regional Water Quality Control Board (RWQCB), and the California Department of Health Services (DHS). You can find the lab reports in our document central.
