We all know that climate change is hurting the Great Barrier Reef. But scores of other less-publicised threats also threaten the future of the natural wonder.
After years of delay, the New Zealand government is pushing ahead on a national plan to clean up the nation’s lakes, rivers and wetlands.
A proposed plan to clean up New Zealand's waterways draws clear limits on the expansion of dairy farming and irrigation, as well as on the use of nitrogen fertiliser in some key areas.
Bores with high iron content can be a haven for disease-causing bacteria.
Many remote communities in Australia's north rely on bore water. But a new microbiology analysis suggests that the chemistry of untreated water can allow disease-causing bacteria to grow unchecked.
Fast tests can help keep people out of the water when it’s unsafe, and let them back in sooner once the coast is clear.
Traditional water quality test results tell you what was happening at the beach yesterday. More real-time answers can be a boon for public health.
How long has that water already been in the system?
In many municipalities, aging water infrastructure is serving fewer people than it was built to accommodate. Out of sight has meant out of mind – but resulting changes in water quality may affect safety.
Regional councils monitor water quality in streams and rivers.
Freshwater data in the latest report on the state of New Zealand's environment suggest improvements in water quality are possible but many gaps in understanding remain.

Premier Doug Ford’s proposal to downgrade Ontario’s environmental watchdog is bad news for the environment, public health and safety, and evidence-based decision-making.
Black water cascaded down Cameron Falls in Waterton Lakes National Park in Alberta after a 2018 wildfire denuded the landscape.
Much of the country depends on water stored and filtered in forests. Fire-scarred watersheds highlight our need for a national wildfire strategy.

Red tide and a blue-green algae outbreak are fouling hundreds of miles of coast, killing fish and driving tourists away from beaches. Some of the causes are natural, but human actions play a big role.
Elon Musk may be on the hot seat for political donations and slurs against a British cave rescuer in Thailand, but his offer to pay for water filters in Flint, Mich., is laudable.

If Elon Musk can help achieve safe drinking water more quickly for every home in Flint, Mich., then he should be lauded. Water is life.
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.
Water quality is one of the major issues that threatens the Great Barrier Reef’s health.

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…
