A new study reveals wide disparities among state-issued Clean Water Act fines, and even among federal fines from regions to region. A law professor explains why it may be illegal.

The Biden administration is finalizing the first federal limits on two compounds, PFOA and PFOS, in drinking water. These so-called ‘forever chemicals’ have been linked to numerous health effects.
Wetlands like this one in California’s Morro Bay Estuary shelter fish, animals and plants and help control flooding.

Farmers are stuck in a chemical war against weeds, which have developed resistance to many widely used herbicides. Seed companies’ answer – using more varied herbicides – is causing new problems.
Chlorpyrifos is widely used on crops, including fruits, vegetables, nuts, corn and soybeans.

What kind of evidence does it require to get a widely used chemical banned? A professor of medicine and former state regulator explains how the case for chlorpyrifos as a threat to public health developed.
‘Cancer Alley’ is an 80-mile stretch of chemical plants along the Mississippi River in Louisiana alongside many Black and poor communities.

The US environmental justice movement dates back to the early 1980s, but federal support for it has been weak and inconsistent. Here are four things Biden’s EPA can do to improve that record.
President-elect Joe Biden opposes proposals to allow uranium mining around the Grand Canyon, which the Trump administration supports.

The Trump administration has used executive orders, deregulation and delays to reduce environmental regulation. Biden administration officials will use many of the same tools to undo their work.
Firefighting foam left after a fire in Pennsylvania. These foams often contain PFAS chemicals that can contaminate water supplies.

PFAS chemicals are toxic, widespread and persistent in the environment, and the federal government has been slow to regulate them. A scientist explains why evaluating them one by one isn’t working.
Fresno, California and the surrounding San Joaquin Valley have some of the nation’s highest levels of fine particle air pollution.

A new study shows that while fine particle air pollution has declined nationwide over the past 40 years, the health and environmental benefits haven’t been shared evenly.
Diesel emissions are a major source of fine particle pollution.

After a 5-year review, the EPA is leaving US standards for fine particle air pollution unchanged, even though recent studies suggest that tightening them could save thousands of lives yearly.

Starting Feb. 6, 2020, California farmers will be barred from using chlorpyrifos on their crops. The Trump administration says more study is needed, but other states are also moving ahead.
Blood samples from pediatric health screenings can provide valuable data for public health research.

The EPA has just adopted a rule that limits what kinds of science regulators can use in setting rules. A scholar explains how this shift could impede his work mapping child lead poisoning.
Vehicles are a major source of particulate air pollution.

Scientists who were appointed to advise the EPA on air pollution kept meeting independently after the agency dissolved their panel. They say current regulations aren’t strict enough.
Many migratory birds, like these sandhill cranes, rely on wetlands for feeding, resting and shelter.

A 2006 Supreme Court ruling created widespread confusion about which wetlands and other waters are federally protected. The Trump administration’s latest action isn’t likely to clear things up.
