Treated wastewater is released into the Fraser River or the ocean. To protect the environment and public health, Metro Vancouver regularly tests and monitors:
- Treated wastewater, to test for substances that could be harmful to aquatic life and to confirm that treatment plant processes are working effectively and meeting regulations
- Areas where treated wastewater is released into the environment
- Recreational waters and beaches (May to September)
- The overall health of the aquatic environment
Results are available in Environmental Management and Quality Control Annual Reports and in monthly operational certificates for wastewater treatment plants.
