Michael Regan, the head of the Environmental Protection Agency, said his agency is taking a series of actions to limit pollution from a cluster of long-lasting chemicals known as PFAS that are increasingly turning up in public drinking water systems, private wells and even food.

The Environmental Protection Agency confirmed the “reddish-orange discharge” that poured into Lake Michigan on Sunday from a steel plant in Portage, Indiana, was caused by high levels of iron, and says there’s no indication of health risks for people who may come into direct contact with the water.

U.S. Steel is reporting that a “rusty colored” discharge that poured into Lake Michigan on Sunday from its plant in Portage, Indiana, was due to elevated iron levels.

Four years after the rusty patched bumble bee was placed on the endangered species list, the U.S. Fish and Wildlife Service has released its final recovery plan for the insect, a plan critics say manages to go too far and yet not far enough at the same time.

Each year, 22 million pounds of plastic finds its way into the Great Lakes – the source of potable water for more than 30 million Americans. We take a look at what can be done to limit plastic pollution.

With possibly just a few weeks left before Exelon shutters a nuclear reactor in Byron, feuding and politically powerful interests have failed to reach a deal that would keep the plant open and otherwise move Illinois toward its renewable energy goals.

Black and Latino neighborhoods in Chicago are more likely to be burdened by industries that pollute the air, ground and water, making environmental justice an important part of the equation as the country moves forward.

Project developers plan to build carbon capture pipelines connecting dozens of Midwestern ethanol refineries, such as this one in Chancellor, South Dakota, shown on Thursday, July 22, 2021. Corn absorbs the greenhouse gas carbon dioxide, but the process of fermenting it into ethanol releases carbon dioxide emissions. (AP Photo / Stephen Groves)

Two companies seeking to build thousands of miles of pipeline across the Midwest are promising the effort will aid rather than hinder the fight against climate change, though some environmental groups remain skeptical.

Monitoring stations have been set up at various parks and preserves in the Chicago region for visitors to snap photos, which are then stitched together in a time-lapse series to document environmental changes.

Some of the Games’ most high-profile moments will incorporate clever examples of “reduce, reuse, recycle,” like medalists standing on 3-D printed podiums made from recycled plastic collected by the Japanese people.

Strides being made against the use of plastic products were derailed by the coronavirus pandemic. Now, a global campaign is encouraging people to choose reusable materials over single-use plastic and get the reduction back on track.
