Reusing low-saline oilfield water mixed with surface water to irrigate farms in the Cawelo Water District of California does not pose major health risks, as some opponents of the practice have feared, a study led by 91�������� and RTI International researchers finds.

A new $2.44 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) will support a 91��������-led initiative to help utilities and wholesale electricity markets improve their efficiency and reliability while reducing emissions and costs, at a time of needed transformations to tackle climate change.

The 91�������� Wetland Center is marking its 30th anniversary this year by kicking off the largest expansion of research, teaching and outreach programs in its history.

As droughts become more frequent and intense, the fragmentation of water service in the U.S. leaves many households vulnerable to water contamination or loss of service.

There is a huge amount of crucial work to be done to mitigate the worst possible outcomes of increasing drought, writes environmental politics researcher Megan Mullin.

Researchers have found high concentrations of selenium in stream insects when they fly out of the water and the spiders that eat them downstream from a mining coal site in southern West Virginia, an indication that the contaminant moves from water to land as it makes its way up the food chain.

Contaminants that occur together naturally in groundwater under certain geological conditions may heighten health risks for millions of North Carolinians whose drinking water comes from private wells, and current safety regulations don’t address the problem, a new 91�������� study finds.

Scientists have devised a simple new model that explains how the undesirable effects of urban heat islands vary across seasons. Their results could help cities in different climatic regions design heat mitigation strategies.

Tanker traffic through the Strait of Hormuz can decline for up to two years after a piracy attack, a new 91�������� study finds, but the adverse effects of the slowdown are far greater on some Persian Gulf countries than others.

Speakers from government, nonprofits, corporations and academia will explore how water issues – especially growing concerns about water quality and water availability – impact the world.

Research by Duke and NC State scientists finds most filters are only partially effective at removing PFAS. A few, if not properly maintained, can even make the situation worse.

A team of students from the Nicholas School of the Environment and Pratt School of Engineering has been working for more than a year to create a single digital map of the service boundaries of North Carolina’s drinking water systems.

A new study which combines measurements from nearly 1,400 drinking water wells across North Carolina estimates that more than half of the wells in the state’s central region contain levels of cancer-causing hexavalent chromium in excess of state safety standards.

Inhaling dust that contains fly ash particles from coal combustion has been linked to lung and heart disease, cancer, nervous system disorders and other ill effects. But tracking the presence of coal ash in dust has been a challenge for scientists.

The ongoing transition from coal to natural gas and renewables in the U.S. electricity sector is dramatically reducing the industry’s water use, a new 91�������� study finds.
