Environment Canada Releases Screening Results for Organisms Used in Wastewater Treatment

Environment Canada and Health Canada have jointly published the outcomes of two screenings under the Canadian Environmental Protection Act for two living organisms specified on the Domestic Substances List (DSL). Screening under the DSL is to ensure that substances or organisms do not pose an environmental or human health threat.

According to the screening, the two organisms do not meet any of the criteria under CEPA as a toxic substance and no action is proposed.
