A study found that if wastewater were injected into a deep portion of the Madison Aquifer, it could potentially contaminate drinking water supplies in other areas.
Encana Oil and Gas has asked for permission to dispose of brine and drilling waste in the aquifer. The company says it would inject the waste into an area where water quality is already poor and which is so deep that it would be an impractical source for drinking water, regardless.
A new study suggests that flaws in how the government measures Yellowstone's grizzly bear population raise questions about whether the animals have recovered sufficiently to merit lifting federal protections.
Lead author Daniel Doak of the University of Colorado says a major reason more bears have been counted in recent years is that more time is now spent counting bears. He says the population could be in decline even as officials consider revoking its threatened species status.
A consortium of environmental groups are suing the U.S. Fish and Wildlife Service for removing Wyoming wolves from the Endangered Species List.
Now that federal protections have ended, Wyoming controls wolf management. The state’s plan allows the animals to be shot on sight throughout most of the state. In northwest Wyoming, there’s a limited hunting season, and the animals are protected for the rest of the year.
But Andrew Wetzler with the Natural Resources Defense Council says those protections won’t maintain a viable wolf population.
