Brazil holds 12% of the world’s freshwater reserves and yet growing water insecurity reveals some of the country’s deepest sanitation inequalities, which are particularly relevant to Marajó, its largest coastal island.
An organism can appear compliant under single chemical regulation while still carrying a potentially concerning mixture burden.
Critics warn Ontario’s new water laws could shift control of public water systems to arms-length corporations, paving the way for private profit at public expense.
Yes, astronauts have to drink water that used to be pee – but their urine is treated extensively, until it is safer to drink than some tap water on Earth.
Current science communications in Cape Town are not serving the public well.
San Francisco argued that Clean Water Act permits should function like recipes that restrict specific ingredients in a dish, rather than telling cooks not to make the dish too salty.
Raw water may not be as safe as it looks. Like raw milk, untreated water comes with dubious health claims and high risks.
There is renewed concern about PFAS or ‘forever’ chemicals in drinking water. Here’s how we keep track of more than 250 potential contaminants to ensure our water is safe to drink.
One of the most liberal US cities is offering the Supreme Court a chance to further restrict federal regulatory power.
A specially coated foil removed more than 99% of E. coli bacteria from water in laboratory tests.
Hard water might dry out your hair and skin − but having hard water isn’t necessarily a bad thing.
Water is everywhere, but freshwater supplies are limited on many Caribbean islands. Rising demand and climate change are worsening water shortages for the people who live here.
There are a lot of myths and strongly held beliefs around one of life’s simplest activities – drinking water.

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.
Nearly 97% of the world’s water is in the oceans, but desalination is no magic bullet for water-stressed coastal cities.
