A quarter of all freshwater animals, including crustaceans, fish and insects, face a high risk of extinction from threats like pollution, farming and dams, a new study has found. Rivers, lakes, wetlands and other bodies of freshwater cover a relatively small amount of Earth’s surface — less than one percent — but are home to […]

Just a little more than one-third of Europe’s surface water is in “good” health or better, a new report from the European Environment Agency (EEA) has found.

More than half of the large lakes and reservoirs on the planet have diminished since the early 1990s due to climate change and human diversion and consumption, an international team of researchers has found. The findings have implications for people who rely on their supply of freshwater for drinking, hydropower and agriculture. The researchers looked […]

Plunging into the ocean or a lake is one of the great joys of summer. But arriving at the beach to find water that’s green, red or brown, and possibly foul-smelling, can instantly spoil the party.

As a toxicologist, I study health risks from both synthetic and natural substances. I’ve conducted research into early detection of harmful algal blooms, or HABs, which are an increasing threat to humans, animals and the environment.

Lake Tahoe – the iconic lake shared by California and Nevada – is the clearest it’s been in 40 years.
