Arsenic in wells in Vietnam suggests dig-deeper approach has issues

For years, scientists and public health officials have known that arsenic threatens the water supplies of millions of people in the heavily populated floodplains of Southeast Asia. A recent study centers on Vietnam’s Mekong Delta, but has profound implications for the people of the entire region. In Vietnam, arsenic is naturally hosted in sediments drained off the Himalayas, which wash into the Mekong.

Arsenic levels in China may be predicted by modeling

In China, arsenic poisoning from groundwater has been a known chronic health issue since at least the 1970s. From 2001 to 2005, the Chinese Ministry of Health tested 450,000 wells, 13 percent of which exceeded World Health Organization (WHO) arsenic standards. However, numbers could be far worse, as only about 12 percent of Chinese counties were screened.

Dangerous dust: Erionite - an asbestos-like mineral causing a cancer epidemic in Turkey - is found in at least 13 states

As North Dakota’s state geologist, Ed Murphy has spent a fair amount of time mapping the geology of the Killdeer Mountains in the western part of the state, hiking up and down buttes of the White River Group and the Arikaree Formation. In the 1980s, he and colleagues mapped large deposits of rocks bearing erionite — a zeolite mineral formed when volcanic ash is altered by water — that may have had some commercial use.

Crystal Ball EARTH: Agriculture: The future will have a different face than the past

Tomorrow’s agriculture is facing an immense challenge. By 2050, the world’s population will reach somewhere between 9 billion and 10 billion people, and a greater proportion of those people will be enjoying a richer diet than today’s population. That means farmers will have to grow twice as much food. The world has already witnessed a preview of what might happen if large populations don’t receive an adequate supply of food: They do not accept their fates passively.

Crystal Ball EARTH: Natural Hazards: Reducing society's risks

The global financial disaster of 2009 has many parallels with catastrophic natural hazards. It struck pretty much without warning, its impact was greatly exacerbated by an incredibly complex system of cascading consequences, and finally, mechanisms supposedly in place to mitigate the worse impacts (regulations, in the case of the financial system) failed. There was awareness that such a meltdown could theoretically occur, but it was considered such a low-probability event that it was evidently not worth planning for.

West Virginia Coal: Dirty water, dirtier politics - but will there be a cleaner future?

Coal has always been king in West Virginia. For more than 250 years, the mining industry has ruled the Mountain State, sometimes running roughshod over worker’s rights, public safety and West Virginia’s mountain ecosystems in the push for higher yields. Coal mining is not without its benefits: West Virginia’s mines produce 15 percent of our country’s coal and half of our coal exports. And the industry provides 40,000 jobs and contributes $3.5 billion to the Mountain State’s economy. Now with U.S.

'The Big Necessity' Reclaiming feces

In her new book, "The Big Necessity: The Unmentionable World of Human Waste and Why It Matters," freelance journalist Rose George argues that experts and citizens alike must overcome their aversion to all things fecal — or else face one of the most serious public health risks on the planet. If handled properly, George says, waste water can even be reclaimed as potable water. Recently, EARTH contributor Brian Fisher Johnson talked with George about her book, which was released on Oct. 14.

Air pollutants from "megacities" a growing problem

Megacities — cities with populations equaling or greater than 10 million people — are producing an unprecedented amount of air pollution, according to scientists at the American Chemical Society's annual meeting in Washington, D.C., on Tuesday.
