How We Do It and What We Are Finding

Marine Environment Monitoring and Assessment Quicklinks

Interactive Map

Click to launch our Interactive Map to find out where our treatment plants are, what they look like, and how we monitor the marine environment near each outfall.

The Marine Programs monitoring and assessment efforts meet the specific needs of each of the CRD's eight outfalls.

While wastewater treatment is designed to reduce suspended solids and biochemical oxygen demand, it is not as effective in removing chemicals, metals or other substances. Many of the substances monitored by Marine Programs are generally found in wastewater from any treatment plant, including those with secondary or tertiary treatment.
