Ingredients from shampoo, sunscreens and other personal care products are turning up in water supplies. Some are toxic or cause hormonal damage to aquatic life, and could threaten human health.
Prairie potholes in South Dakota are important breeding and feeding areas for many types of birds. Under the Clean Water Rule, farmers cannot fill them in or discharge pollutants into them without a permit.

President Trump signed an executive order to roll back the 2015 Clean Water Rule. Two water experts explain why the rule alarms farmers and ranchers concerned about over-regulation.
The bad old days: Public and political support for the EPA was highest when environmental problems like air and water pollution were more obvious than current problems like climate change or endocrine disruptors.

Low-income residents in Puerto Rico are fighting disposal of toxic coal ash in their communities. They’re also campaigning to shift from coal energy – the source of the problem – to solar power.
Wastewater treatment systems around the world are hamstrung by outdated tests that don’t identify a growing array of pathogens or identify the sources of pollutants.
Detail from a satellite photo of Lake Okeechobee’s algae bloom and the St. Lucie canal into which water was released. Rising water levels from heavy winter rains had water managers worried that water would breach the dike.

Excess nutrients from farm fields cause widespread water pollution across the U.S. Bioreactors – essentially, ditches filled with wood chips – are emerging as a way to reduce nutrient pollution.
Mineral processing tailings are pumped into a storage facility. Are there still valuable commodities in this waste?
Identifying mine waste materials as economic resources will help support global demand for critical metals, boosting the mining industry during the downturn. All with environmental benefits.
Microbes living on corals are instrumental in keeping coral reefs healthy.

A new study provides insight into coral-dwelling microbial communities and how they react to pollution, overfishing, and climate change. What does it mean for the Great Barrier Reef?
A market that lets sugar cane farmers trade ‘nitrogen permits’ could help keep a cap on fertiliser use.

You’ve heard of cap-and-trade schemes for greenhouse gases. Perhaps we also need one to limit the amount of fertiliser runoff onto the Great Barrier Reef.
Climate change is warming Lake Tahoe and could alter its chemistry in harmful ways.

Lakes contain most of the fresh water on Earth’s surface. Recent research at Lake Tahoe in the Sierra Nevada mountains shows that climate change could alter lake chemistry, threatening these sources.
Fixing water pollution on the Great Barrier Reef will take a huge effort.

Parents in three Australian states are being given misleading advice about the dangers of lead to babies and small children – including failing to warn pregnant women about miscarriage risks.
Nutrient runoff is one of the major contributors to crown-of-thorns outbreaks.
