This year’s Blue Drop Audit report of water quality in South Africa has found that 46% of water supply systems are contaminated and over two thirds of wastewater treatment plants are close to failure.
Researchers are finding alarming concentrations of persistent pollutants such as PFAS in Australian dolphins. These record-breaking levels are cause for concern.

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.

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.
PFAS can be found in hundreds of water systems in the U.S.

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?
