The federal government is now taking comments on alternatives to a project in western Colorado notorious for causing earthquakes. 

The Bureau of Reclamation is looking for replacements for the Paradox Valley Unit, located in a remote part of western Colorado’s Montrose County. The agency released a draft environmental impact statement for those replacements Friday.

It’s well-established that injecting wastewater from oil and gas operations deep into the ground can cause earthquakes. New research shows that in some cases those earthquakes can keep happening long after an injection. 

Nara Bopp was working at a thrift store in Moab, Utah the morning of March 4 when her desk started moving. 

“I immediately assumed that it was a garbage truck,” Bopp said.

  • According to a new state study, Colorado has a significant shortage of hospital beds for people suffering from mental illness and has increased needs for people behind bars.
     
  • A 3.9 magnitude earthquake shook Las Animas County last night, with an epicenter about 24 miles west of Trinidad.

Land near the Colorado-New Mexico border has recently been caving inwards in an area where a 5.3 magnitude earthquake took place in 2011. As KRCC’s Dana Cronin reports, scientists at the United States Geological Survey are pointing to wastewater disposal as a potential trigger.
 

Higher magnitude earthquakes are a rarity in Colorado, making the 2011 quake of special interest to scientists. Research showed a possible cause as wastewater injection which involves the pumping of large volumes of fluid into the Earth, creating high-pressure conditions.

Scientists Study Trinidad-Area Earthquakes

Jan 28, 2014

Scientists with the US Geologic Survey are studying the relationship between earthquakes, gas drilling and the practice of re-injecting waste-water into the ground. They're looking at area around Trinidad in Southern Colorado, where the number of earthquakes has been growing.  Trinidad currently averages about eight magnitude-3 earthquakes a year.

Geophysicist Justin Rubinstein with the USGS, says there appears to be a correlation to the waste water injection process, but  adds it happens at only a handful of the 35,000 injection wells across the country.
