Degradation of Phytoplankton and Zooplankton BUI Redesignation

We want to know what you think about the recommendation by the Detroit River Canadian Cleanup to change the status of the Degradation of Phytoplankton and Zooplankton populations beneficial use impairment (BUI) from ‘requires further assessment’ to ‘not impaired’. Your input is valuable to us and is much appreciated.

The technical report on which this recommendation is based and the fact sheet associated with this report can be found below. This report will provide you with all information required to provide comments on the proposed re-designation.

Degradation of Phytoplankton and Zooplankton Populations

Phytoplankton and zooplankton populations make up the base of the aquatic food web and are an important food source for fish. Insufficient data on the phytoplankton and zooplankton populations in the Detroit River led to additional studies including a comprehensive study in 2019 by the Department of Fisheries and Oceans. Study results indicate that phytoplankton and zooplankton populations are naturally low in the river due to expected river conditions, not human activities. Based on the research findings of all studies, there is no evidence of impairment to the plankton populations in the Detroit River and a “not impaired” status is being recommended by the Detroit River Canadian Cleanup.

What are plankton?

Submit your comments in the form below. All comments received will be reviewed and addressed by the Detroit River Area of Concern Remedial Action Plan members. All comments will be included in a summary report (which will be created after the deadline passes) to inform stakeholders about the public’s opinions towards the proposed status change of the BUIs. The deadline to submit comments is December 31, 2020.

We expect the comment form to take no longer than 5 minutes to complete. If you have any questions or concerns please contact Jacqueline Serran at postmaster@detroitriver.ca or at 519-776-5209 ext. 356.
