Pollution Prevention

Welcome to the City of Superior Pollution Prevention Site

The City of Superior is the largest contributor of wastewater to Lake Superior in the state of Wisconsin. We are committed to protecting and preserving the greatest of the Great Lakes in part through our educational outreach programs. These programs are part of a broader program carried out by the Lake Superior Binational Program to restore and protect the Lake Superior Basin.

Mercury

What is mercury?

Where is it found?

What does it looks like?

Why do we use it?

Why do we have fish advisories?

What symptoms do you get if you have too much mercury exposure?

These questions and more are covered when we visit schools to teach students and teachers about mercury.

Northwest Regional Clean Sweep conducted Mercury collections in ten northern Wisconsin counties.

Hundreds of pounds of mercury and mercury containing products have been collected

Dental amalgam, the material in "silver" tooth fillings, contains approximately 50 percent of the metal mercury. Working with local dentists helps keep mercury out of our wastewater and Lake Superior.

Drs. Alan and Mark Callaway received a new amalgam separator as part of our Dental Program

Jane Schlichting presents the Rebec Separator to Dr’s. Mark and Allen Callaway.

Many groups can hold Thermometer Exchanges. 

These students from Pattison School gave digital thermometers to everyone who brought in a mercury thermometer.

Contact us if you would like to hold a thermometer exchange.

Educational displays inform the public about mercury, burn barrels and dioxin, stormwater runoff, energy conservation, watershed information, etc.

Have an event you'd like us to attend? Have an idea for an environmental message? Want to develop your own display? Contact us for information.

Stormwater run off is captivating the attention of these fifth-graders.

Using a watershed model, students can see the effects of erosion, excessive pesticide use and pollutants. This model helps visualize how pollution far away from the water can make its way to Lake Superior.

A rain garden demonstration project has recently been started at the Wastewater Treatment Plant.

Rain gardens are a great way to slow down stormwater runoff, help prevent pollution, and stop erosion.

If you are interested in a tour of the rain gardens or a presentation on "How to make a rain garden", please contact us to schedule one!
