The Detroit River has been a dumping ground. Now, its health is improving

The Detroit River has served as an economically significant waterway connecting Windsor and Detroit. But, it has also suffered pollution for decades as a result of its importance. The Detroit River Canadian Cleanup is now sharing good news for the health of the river.

Since 1987, the Detroit River has been designated as an Area of Concern

The Detroit River's reputation has become notoriousover the decades due to pollution, but local scientists say restoration efforts are working, and they want to see those improvements reflected in theriver's environmental status.

The Detroit River has served as one of the vital economic links between Detroit and Windsor. In 1987, it was identified as an area of concern under the Great Lakes Water Quality Agreement between Canadian and American federal governments.

Windsor's harbour master previously told CBC that Detroit River has historically been a dumping ground.

Cannons dating back to the first French settlers have been discovered there, he said. There arealso many bottles dating back toprohibition.Firearms have also turned up.

Matt Zuidema discusses his passion for scuba diving and some of things he's found, including two cars in the Detroit River.
The Detroit River Canadian Cleanup (DRCC) was established in 1998 to restore the river. As an Area of Concern, 14 beneficial use impairments (BUIs) were identified to measure the impacts of pollution.

The term "BUI"is used by scientists to measureimpairments in human health, economics, ecology and environment due to poor water quality in the river.

ActingDetroit River Remedial Action PlancoordinatorSarah Lanoueexplained these units of measurement further to CBC News.

"If you break it down and look at the term, 'beneficial use' would be something that you enjoy getting out of the river,like fishing or going to the beach," Lanoue said. "So when they're impaired, it's when you can't do those things."

Since the action plan was established, 10 of the river'sBUIshave been redesignated from "impaired"to "not impaired"according to a press release from theDetroit River Remedial Action Plan.

They are now recommending that a further two BUIs be redesignated: the fish portion of theDegraded Fish and Wildlifecategory andthe entirety ofBird or Animal Deformities or Reproductive Problems.

A national problem

The Detroit River is designated an Area of Concern,but this designation also applies to multiple waterways across the nation.

"There's the St.Lawrence River [and]there's different areas within the Great Lakes that are considered to be impaired," Lanoue explained. "We're trying to delist the Detroit River as an area of concern."

Part of this ambition is to study a river's health over time and conclude whether it has surpassed the threshold for its BUI designations. In terms of theDegraded Fish and WildlifeBUI, Lanoue said that there's not enough evidence to suggest that the wildlife category can be redesignated.

"In this instance, we are just looking at the fish populations because we don't have enough scientific information yet to determine whether the wildlife populations are not impaired anymore," she said.

But, in terms of the other categories, "We actually have enough scientific evidence to determine that they're not impaired," Lanoue said.

The DRCChosteda public consultation open house on Oct. 5 atthe Ojibway Nature Centre to share information on environmental improvements to the Detroit River.

At the open house, ecotoxicologistat Environment and Climate Change Canada Shane DeSollasaid that several sentinel species were assessed in terms of theDegraded Fish BUI, including northern leopard frogs, snapping turtles and treeswallows.

Involving community

The DRCC works locally with stakeholders and volunteer organizations to improve the Detroit River's health.

She hopes that the potential lifting of BUIscould reflect the work that the DRCC has done over the years.

"We do a lot of large-scale habitat projects," she said. "[During] the Peche Island project we added a bunch ofshoreline improvements and barriers to protect the fish that are in the water, and to improve fish spawning."
