If not properly managed, heavy metals such as arsenic can accumulate in landfills and leach into soils and groundwater.

Rapid and accelerating groundwater level declines are widespread in dry climates where groundwater is used for irrigation. But some communities have found ways to turn things around.
What happens underground doesn’t stay underground. If we overexploit groundwater and kill off its species, we put surface species – including us – at risk.
As the war between Hamas and Israel grinds forward, two experts explain how Israelis and Palestinians have cooperated to tackle their region’s water challenges.
Saltwater intrusion is bad for human health, ecosystems, crops and infrastructure. Here’s how seawater can move inland, and why climate change is making this phenomenon more frequent and severe.
Better monitoring of groundwater is important for sustainable management.
South-west Australia relies on groundwater for three-quarters of its water use. But a new study of the region’s caves has found a drying climate is having a dramatic impact on this precious resource.
We’ve blown past the safe and just limit for vital Earth systems, from climate change to the biosphere and the use of fertilisers and freshwater. For humans to thrive means living in safe limits
Aquifers are highly prevalent across Africa – but they’re not always going to be usable.
The slow release of information about the chemical spill and results of air and water tests have left many questions about the risks and long-term impact.
Urban infrastructure was designed to take stormwater out to the ocean quickly. Now, California needs that precious water.
There are fears the Northern Territory government will allow gas and other industries to extract substantially more water from the environment than is currently allowed.
While we know how global changes in freshwater pose risks to humans and ecosystems, we know less about how people and ecosystems will respond to these global freshwater challenges.
High intensity rain has actually increased, which is topping up underground water stores.
New regulations for protecting water resources during oil exploration are inadequate and should be reviewed.
The UK is no stranger to drought – especially southern England.
Accra has become susceptible to floods due to encroachment on wetlands.
We need a radical rethink of water resource planning. Strategies should include reusing water and moving water physically to water-scarce areas.
Millets have been around for thousands of years – and are back in fashion.
When groundwater comes to the surface, sunlight and air convert organic molecules to greenhouse gases. That’s going to be a problem as we will need this water more as the world warms.
