Health workers are piecing together a complicated puzzle in El Paso County, Colo. In January, three cities — Security, Fountain and Widefield — noticed synthetic chemicals known as PFCs in the drinking water.

A 5.8-magnitude earthquake rocked Oklahoma on Saturday, prompting Gov. Mary Fallin to declare a state of emergency. On Wednesday, officials said it was the strongest quake in the state’s history.

The quake followed a string of thousands of smaller tremors that have raised questions about the impact of drilling for oil and gas, and the controversial technique of hydraulic fracturing, also known as fracking.

Customers of the state’s largest electric utility will pick up the tab for environmental compliance projects and plant upgrades over the next few years, The Oklahoman’s Paul Monies reports.

Environmental groups have challenged a decades-old exemption for oil and gas drillers from federal law and the energy industry and state regulators are worried a court ruling against the EPA and “the possibility of new regulations,” The Oklahoman’s Paul Monies reports.

Oklahoma Forestry Services says it's closing four offices and reducing services as part of a restructuring program forced by budget reductions.

Forestry Services Director George Geissler says the agency plans to reallocate resources to maximize its remaining services. While some services will no longer be available to landowners in western Oklahoma, all 77 Oklahoma counties will continue to receive wildfire suppression support.

The Mendenhall Glacier is visible from the visitor center parking lot. But it's still pretty far and if you traveled all the way to Juneau, Alaska, you probably want to get up close to the blue tinted ice.

Touching the face of the glacier can be tricky. You're separated by cold, silty water, and a hike over the ridge could take hours.

Visitor center staff know that. And inside, they use it to prove a point.

There was a time when Sandra Gologergen's freezer never ran out. Packed with traditional Inuit foods like whale, walrus, seal and fish, her freezer has been an essential lifeline, ensuring her husband, three kids and grandson make it through the long harsh winters of Savoonga, Alaska.

"Then that changed," she says.

The water supply for communities in the Canadian province of Saskatchewan is threatened by an oil spill that dumped an estimated 66,000 gallons of heavy oil, along with natural gas used to dilute it, into a major river.

The pipeline that broke is owned by Husky Energy Inc. The site of last Thursday's leak is within 1,000 feet of the North Saskatchewan River.
