‘Living materials’ made with genetically engineered bacteria and Jell-O-like gel could make pollutants in water bodies nontoxic.
Most of the world washes their clothing by hand.
Simply trying to avoid synthetic clothing won’t fix our microfibre pollution problem

A pipeline that has carried Canadian oil and gas across Wisconsin and Michigan for 70 years has become a symbol of fossil fuel politics and a test of local regulatory power.
New restrictions on PFAS and other potentially hazardous chemicals in Australia present an opportunity for industry to develop alternatives for new, safe and clean products.

Millions of people worldwide are exposed via soil and water to arsenic, whether naturally occurring or related to pollution. Chronic exposure is linked to the formation of cancer stem cells.
Many ecologically important wetlands, like these in Kulm, N.D., lack surface connections to navigable waterways.
In Sackett v. EPA, a suit filed by two homeowners who filled in wetlands on their property, the Supreme Court has drastically narrowed the definition of which wetlands qualify for federal protection.

The tiny organisms that cause harmful blooms of algae can have a big impact on your trip to the shore. A toxicologist explains what causes these events and how to keep people and pets safe.
Many of our rivers are overloaded with nutrients from fertiliser run off and wastewater. Algal blooms, fish kills and poor water follow. One solution? Nutrient offsetting.

The drinking water systems serving over 70 million people may not meet newly proposed water quality standards. It could cost hundreds of billions of dollars to fix that.
The Clean Water Act was meant to keep pollution out of U.S. waters.

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.
Every household is more likely than not to have dusts containing PFAS chemicals at low concentrations. But how worried should we be about the risks to our personal health?
