An audit of Sydney's drinking water has found worryingly high salinity. If the biggest water catchment in the country has problems, what about regional and rural Australia?
South-East Queensland residents need to prepare for more regular floods, according to new data.

We rely on climate data to help us make important decisions for our future, such as building infrastructure. But what if a region's climate has long been more volatile than we realised?
The new funding is focused on measures that are already in the foreground.

The federal government's new $500 million funding package for the Great Barrier Reef seems predominantly focused on the tactics that are already being tried, without much success.
What if air quality standards were decided not by governments but by a dedicated federal body?

Environmental and health groups have called for the creation of a non-political federal agency with the power to rule on pollution levels - much like the Reserve Bank does for interest rates.
Community-led research in the Inuit community of Rigolet, Labrador, helped identify dirty water containers as a source of drinking water contamination.
Can community-led research help address Canada's Indigenous water security issues? One project from the Inuit community of Rigolet in Labrador suggests it can.

The updated plan for improving water quality on the Great Barrier Reef still doesn't address the need to curb intensively farmed crops such as sugar cane, and to enforce existing environmental laws.
If you have bought an Aldi “The Spiral Spring Mixer Tap” you should not use water from it for drinking or cooking until investigations of reported lead contamination is complete. What we know The media…
Turtle hatchlings could be released into the Murray River to manage the sudden influx of dead carp.

Millions of dead carp will fill the Murray-Darling Basin after the government releases a targeted virus. Scavengers like turtles and crayfish might help – as long as we protect them.
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.

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.
