WLSSD celebrates 50 years of Clean Water Act

“As a nation, especially of the time, it was an impressive accomplishment,” Marianne Bohren, executive director of the Western Lake Superior Sanitary District, said during a public tour Tuesday.

DULUTH — Community members joined the Western Lake Superior Sanitary District on its 50th anniversary Tuesday to celebrate northern Minnesota’s prospering lakes and rivers under the Clean Water Act .

Festivities included informational, water-themed games for all ages, guided tours of the facility, and an opportunity to learn from Duluth’s local water-waste experts — all over food and beverages provided at no cost (and of course, clean water).

The Clean Water Act was established in 1972 with the purpose of regulating industrial pollution entering bodies of water.

“As a nation, especially of the time, it was an impressive accomplishment,” WLSSD Executive Director Marianne Bohren said.

A lifelong area resident, Bohren described her experience growing up near the St. Louis River prior to the regulation of industrial wastewater.

“Do you see this sludge? That is the St. Louis River prior to the act, we could not enter the water” she said. Bohren was pointing to a decades-old black-and-white photograph of a man shoveling the river's top layer. The water’s surface had a dark, dense layer of sludge that was inches thick.

Such sludge began as industrial wastewater that was dumped into free-flowing sources. As a result, its toxic compounds leached oxygen from the water and depleted its quality. Species die-off, waterborne illnesses and the deterioration of the surrounding environment are some hits the St. Louis River valley took as a result of such pollution.

However, due to governmental prioritization of water infrastructure catalyzed by the Clean Water Act, the area’s first solid-waste treatment facility, which was planned and built in six years, began operations in 1978. “So much was accomplished in such little time, it’s truly impressive,” Bohren said.

Bohren recalls that only two years after industrial wastewater was both treated and regulated, the St. Louis River and its tributaries had undergone natural restoration.

Today, the district serves clean water to 17 townships and cities, including Duluth, Carlton and Cloquet. That’s over 144,000 residents, 530 square miles and approximately 40 million gallons of wastewater being treated every day.

For first grader Anton Alfonsi, the sour smells were worth seeing where his water comes and goes. “That would be a lot of work,” he said. After touring the facility, he applauded the 100-plus workers that contribute to the facility's operations.

“It could absolutely be considered a public service,” said Nathan Parr, WLSSD tour guide and community program coordinator.

Put simply, Anton only needed one word to describe how clean water makes him feel: “Happy.”

Since Mars’ surface is especially iron-rich, scientists looked for comparable iron-rich rocks on Earth. And they can be found around Duluth.
From the column: "A consumer substituting a cotton bag for plastic would need 136 years of weekly grocery store trips to be as environmentally friendly as single-use plastic is."
From the column: "Instead of testing the proposed mine against environmental laws and standards, the government succumbed to political pressure, ignored the established process, ... and issued a blanket, decades-long ban based on ... hypothetical scenarios."
From the column: "It is ... limited by law to a 20-year term. The Minnesota Legislature and U.S. Congress could ... permanently protect the Boundary Waters watershed from copper mining."
From the editorial: "Thursday’s federal order kneecapped our corner of the state, ... ignoring the thorough, years-long environmental-review and permitting processes ... that have led to countless safe projects."
From the column: "A dedicated group of scientists, attorneys, and front-line community members have pushed hard to get an unreasonable, unreliable, and dangerous mine plan rejected."
The editorial was illustrated with a photograph of Second Creek, which has been degraded by the mining industry — without suffering stiff-enough penalties or clean-up requirements.
