A long-awaited NZ$700 million package to clean up New Zealand's rivers and lakes has disappointed some of the government's expert advisers – especially a delay on setting clear pollution limits.
A new report on New Zealand's lakes and rivers confirms that many freshwater ecosystems are in decline and warns that climate change will exacerbate existing threats.
Floods will undoubtably wash pollutants into water reservoirs. Are we prepared enough to protect our drinking water?
If you want to swim in the Yarra River, you can check the water quality to see if it's safe. If you want to swim in the Nepean River, you can't – and that's a problem.
Warnings about poor drinking water quality are in place in some areas affected by the bushfires.
Damage to water supply infrastructure and catchments during and after bushfires inhibits the treatment processes that normally make our water safe to drink.
The New Zealand government has announced a partnership with the farming sector to develop voluntary measures to reduce farm emissions.
The New Zealand government's decision to partner the farming sector to encourage voluntary reductions in farm emissions failed to acknowledge that agricultural emissions also affect water quality.

Few feel the pain of the Great Barrier Reef's decline more acutely than the scientists trying to save it. Ahead of a UN climate summit, two researchers write of their grief, and hope.

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.
Celebrations for Kumbh Mela, 2019.
Kumbh Mela is the world's largest congregation of people – so large, it's visible from space. However, river pollution is a major issue here and new solutions are needed.

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.

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?
