Iona Island Waste Water Treatment Plant – Metro Vancouver’s largest wastewater plant – currently operates at a primary level, filtering out only large debris and dissolving some organic matter before entering the Salish Sea, therefore contaminating the environment and allowing for the introduction of microplastics to the environment. Discussions are underway regarding an upgrade to a tertiary level, the appropriate treatment level for the 207 billion litres of wastewater that enters the Salish Sea.
