An expert in water science explains the mysterious chemistry behind water treatment.
Water quality is one of the biggest threats facing the Great Barrier Reef.
Australia will almost certainly miss its water quality targets for the Great Barrier Reef.

We're going to miss the Great Barrier Reef's water quality targets unless we help farmers better
The idea that we make rational choices is the basis for how businesses and governments make their plans. But psychologists have been asking some awkward questions.
Protecting the Great Barrier Reef’s water quality finally has a hard dollar price on it.
A groundbreaking new economic study has found that investing A$8.2 billion would get us very close to hitting targets to cut water pollution into the Great Barrier Reef by 2025.
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.
Toxic algae blooms like the intense one now fouling Florida’s waterways harm wildlife and people in various ways. They're also on the rise.
Malcolm Turnbull and his colleagues have pointed $1 billion of the government’s existing green energy funding towards the Great Barrier Reef.
The Coalition has ramped up the race to fund the Great Barrier Reef's protection. All three major parties have promised hundreds of millions of dollars, but where from, and what will they be spent on?
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.
Fixing water pollution on the Great Barrier Reef will take a huge effort.

Efforts to combat water pollution on the Great Barrier Reef aren't working, according to a new government report.
The Great Barrier Reef’s health has declined in recent years.

The Great Barrier Reef is in trouble, and the upcoming election is our last chance to lock in plans to save it.

Banning fishing helps fish, but it also helps reef recover from cyclones, disease, and coral bleaching.
There are still concerns over the impact of upstream coalmines on water in the Warragamba Dam, a key part of Sydney’s water network.

The cutting of senior staff from WaterNSW, the body that oversees the safety of Sydney's water supply, poses serious risks to Australia's most complex water network.
Lead can linger in bones.

Lead might not be in paint or gasoline anymore, but since it doesn't break down in the home or the environment it remains a problem throughout the U.S.
Millions of people in Africa don’t have access to adequate sanitation.
Despite improvements, there are still millions of people without adequate sanitation in Africa. Sustainable solutions that can be replicated elsewhere are being developed in South Africa.
Algae overload: Lake Erie algal bloom 2011.
The same conditions – ultimately tied to nutrient runoff – that created the damaging toxic blooms and dead zones in US waterways of recent years are forecast to return this year.
Unless water is governed properly, the African continent will face massive problems in the coming years.
Managing Africa's water sources is a matter of vital importance for people to have any hope of surviving on the continent
Texas: leading the ‘Shale Revolution.’
The US Geological Survey recently confirmed what many people have already felt: that the rapid spread of fracking has led to more earthquakes.
The ultimate problem: intensive corn production.

A law signed into effect last week seeks to reduce fertilizer runoff that causes toxic algae blooms. But to really address the problem requires taking a hard look at how America farms.
The World Heritage Committee has called for a comprehensive assessment not just of the threats to the Great Barrier Reef, but of their cumulative effect.

The government says it has met all of the recommendations for safeguarding the Great Barrier Reef. But a close reading of the dozens of UN recommendations shows that many have been only partly fulfilled.
The Bellinger Snapping Turtle is under threat, and that bodes ill for the entire ecosystem.

The Bellinger River Snapping Turtle is under threat of extinction, and it suggests something very wrong with the whole ecosystem.
