Oil and gas wastewater radioactivity persists in Pennsylvania stream sediments
Photo: Treated oil and gas wastewater flows into a stream in western Pennsylvania. A new Duke study finds stream sediments at disposal sites such as this one have levels of radioactivity that are 650 times higher than at unaffected upstream sites.

Radium contamination in water most widespread in Texas, environmental group says
More than half of Americans could be drinking tap water tainted with a radioactive element. A new report from the nonprofit Environmental Working Group (EWG) finds more than 170 million people are exposed to radium in their drinking water. That could increase the risk of cancer. When Dennis Taylor moved with his wife and two…

170 Million Americans Drink Radioactive Tap Water
Drinking water for more than 170 million Americans in all 50 states contains radioactive elements that may increase the risk of cancer, according to an Environmental Working Group (EWG) investigation released Thursday. Radiation in tap water is a serious health threat, especially during pregnancy, and the U.S. Environmental Protection Agency’s legal limits for the most…

26,000 tons of radioactive waste under Lake Powell
The West’s uranium boom brought dozens of mills to the banks of the Colorado River — where toxic waste was dumped irresponsibly. This article was originally published on The River of Lost Souls and is reproduced by High Country News with permission. Beneath the murky green waters on the north end of Lake Powell, entombed…

Scientists on Causes of High Radium Levels in Key Midwestern Aquifer
Oxygen levels, dissolved minerals among factors responsible for high concentrations of radium in untreated water from aquifer that underlies six states U.S. Geological Survey scientists have shed new light on processes that happen deep underground. These processes — which cause radium to leach from aquifer rocks into groundwater — are responsible for high concentrations of…
