After reports of a dangerous gas being emitted from several suburban industrial sites, U.S. Sen. Tammy Duckworth and other lawmakers have introduced a bill that would force the EPA to more quickly disclose similar public health risks. 

A new analysis shows that closing Chicago's final two vehicle emissions testing facilities came at a cost to hundreds of thousands of city drivers, with the biggest impact on low-income and minority drivers. 

The ongoing probe into harmful levels of brain-damaging manganese on Chicago’s Southeast Side has turned up another, more familiar neurotoxin: lead.

A Bensenville-based home renovation company has agreed to pay nearly $53,000 for alleged violations of federal laws designed to protect against exposure to lead-based paint. 

Soil samples have been collected from more than 100 properties as the U.S. Environmental Protection Agency continues to assess the threat posed by brain-damaging manganese emitted from nearby industrial sites.

Local public health experts are set to testify at a Chicago hearing next week on the Trump administration’s proposal to repeal the Clean Power Plan, which established limits on pollution from power plants. 

A new federal grant aims to help educators use the Chicago River as a “living classroom” to teach students about water quality issues. 

Former EPA chief Scott Pruitt said his proposal would increase transparency, but opponents say it will keep certain scientific studies out of the hands of EPA decision-makers and addresses “a ‘problem’ that does not exist.”

After touring Chicago’s industry-dominated Southeast Side on Thursday, U.S. Sen. Dick Durbin pressed the Environmental Protection Agency to increase monitoring of brain-damaging manganese dust. 

In a joint statement released Thursday, attorneys general from nearly 20 states, including Illinois, said weakening the so-called clean car rules would cause Americans to breathe dirtier air and pay higher gas prices.

General Iron announced plans earlier this month to move its scrap metal yard from Lincoln Park to the Southeast Side, where residents are concerned about the company’s environmental track record.

Illinois Attorney General Lisa Madigan has joined her counterparts in 14 states in suing the EPA over its suspension of a rule that limits the number of highly polluting trucks on the nation's roads. 

Hours before the resignation Thursday of EPA head Scott Pruitt, a federal judge ruled that Pruitt had violated the Clean Air Act by allowing Illinois and two other states to avoid conflict-of-interest rules. 

The scandal-ridden EPA chief resigned Thursday amid a number of ethical and legal violations over his travel spending, security costs and ties to industry lobbyists. 

Water testing at a Chicago day care center showed at least one sample 16 times higher than the lead level allowed in bottled water, according to a new report from an environmental watchdog group. 

As part of its investigation into high levels of manganese on the Southeast Side, the EPA will hold an open house this week to talk about soil sampling and sign residents up for testing.
