Alberta cattle rancher Howard Hawkwood has a beef with the local fracking industry. He’s convinced the controversial technique for gas extraction is responsible for killing off 18 of his cows and large swaths of his property near Airdrie, Alberta.
“These are the dead spots in the field, where my cows have urinated. This all showed up last spring…We’ve actually taken soil samples of the dead spot and a sample from a foot and a half away and we’ve got high levels of radon, barium, uranium, strontium, and magnesium is extremely high.”
Millions of barrels of wastewater trucked into Ohio from shale-gas wells in Pennsylvania might be highly radioactive, according to a government study.
Radium in one sample of Marcellus shale wastewater, also called brine, that Pennsylvania officials collected in 2009 was 3,609 times more radioactive than a federal safety limit for drinking water. It was 300 times higher than a Nuclear Regulatory Commission limit for industrial discharges to water.
The December 2011 study, compiled by the U.S. Geological Survey, also found that the median levels of radium in brine from Marcellus shale wells was more than three times higher than brine collected from conventional oil and gas wells.
“These are very, very high concentrations of radium compared to other oil and gas brines,” said Mark Engle, a U.S. Geological Survey research geologist and co-author of the report.
It will take years for the full health impact of natural gas development to be known. Authors of a new peer-reviewed study urge that steps be taken now to protect the health of humans and the planet. Modern Natural Gas Development and Harm to Health: The Need for Proactive Public Health Policies argues that the natural gas industry must make changes now to protect the health of people and animals.
The paper provides a literature review of unconventional natural gas development and its effects on human health. It focuses on impacts on children’s health, general harm to health, water contamination and air and soil contamination.
